Initial configuration of the db2 probe is done by defining connections and profiles for monitored instances, using the GUI. The probe may be running locally on the database server, or it may be configured to run as a remote client. Every profile will run in its own thread. Note: All windows containing lists are resizable. Click Apply to activate any configuration modifications done. This section contains the following topics: Probe Defaults (see page 12) Probe Configuration Interface Installation (see page 13) Probe Configuration (see page 13)

Probe Defaults At the time of deploying a probe for the first time on robot, some default configuration will get deployed automatically. These probe defaults could be Alarms, QoS, Profiles and so on which save time to configure the default settings. These probe defaults will be seen on a fresh install, that is no instance of that probe is already available on that robot in activated or deactivated state.

12 db2 Guide

Probe Configuration Interface Installation

Probe Configuration Interface Installation The probe configuration interface is automatically downloaded and installed by the Nimsoft Infrastructure Manager when the probe is deployed on a robot.

Probe Configuration This section contains specific configuration for the probe.

Setup Tab The Setup tab contains two sub tabs - General and Message pool. By default, the General sub tab is selected.

General Tab The General tab enables to set the general run-time parameters regarding the db2 probe.

This tab contains the following fields: Generate status only Instructs the probe to only generate status, not to issue an alarm when a threshold is breached. Select the Status tab to see the status for the different checkpoints.


Probe Configuration

Clear Alarm On Restart Allows you to clear alarms on restart. By default, this check box is selected. Alarm severity filter Sets a "filter" on which severity levels are considered as alarms. The db2 probe is capable of checking many areas of the databases. Some events that are generated are vital and key to the performance and availability of the database. As a database administrator, you may want to pass the important events on to the operations centre or helpdesk, so the event can trigger pagers, email etc. The Alarm severity filter will consider the events matching the selected severity level and higher as alarms, and pass these on whenever the Generate status only option is not selected. Example: If you set this to major, then only messages with severity major and upward are considered as alarms. Status Auto-Update Lets you activate/deactivate the Status Auto-Update functionality as described below: The Status Auto-Update parameter (number of seconds) specifies the automatic refresh interval of the Status Window on the Status tab. If you set this parameter to a value higher than 0 and then select a profile on the Status tab, the status will be automatically updated every x seconds. The checkpoints of the selected profile will be displayed until selecting another profile. Note: This parameter is a "dialog" value - it means it is not saved in the configuration file, but in the machine running the dialog (same as for example windows size). Log Size Sets the size of the probe’s log file to which probe-internal log messages are written. Default: 100 KB. When this size is reached, the contents of the file are cleared. Log Level Sets the level of details written to the log file. Log as little as possible during normal operation to minimize disk consumption. QoS V2 compatibility Provides backward-compatibility to V2 framework. All Database Status Provides the option to get the status of all database otherwise only for the default database.

14 db2 Guide

Probe Configuration

Connections Tab The Connections tab contains the list of various connections to instances that the db2 probe will monitor. You need to specify user name, password and service name you want to use to connect to the instance. The password information is encrypted and placed into the configuration file. A connection can be used by more than one profile.

The list contains one predefined connection that you may modify to your preferences. You may add, edit, delete and copy connections.

18 db2 Guide

Probe Configuration

Edit Connection Dialog Right-click a connection and select Edit. The Edit Connection dialog opens for editing.

This dialog contains the following fields: DSN Specifies the ODBC Data Source Name. For details, refer Define an ODBC Connection (see page 21). Description Provides short description of the connection. User ID Defines the user id with SYSADM, SYSCTRL or SYSMAINT authorization. Password Defines the valid password. Instance node Specifies the node name under which the instance you want to connect to is catalogued in the node directory. Default DB name Specifies the database name used for connection tests (for example in i_check_dbalive).


Probe Configuration

Retry attempts Indicates the number of attempts the probe should try to repeat connection in case of failure. "0" means only the initial connection will be done. Retry delay Specifies the time for which the probe will wait between two connection attempts. Timeout Specifies the time for which the probe will wait for answer before it aborts the connection process. Test button Enables to test if the connection can be made. If successful, it will return the instance name and its version number. If not, an error message will be returned.

20 db2 Guide

Probe Configuration

Define an ODBC Connection You must create an ODBC connection to specify a DSN while defining a new connection. Follow these steps: 1.

In the Control Panel, select Administrative Tools.

2.

5.

Follow the steps through the wizard to finish the definition.


Probe Configuration

Profiles Tab The Profiles tab contains the list of sample profile that you may modify to your preferences. Every profile will run as a separate thread and multiple profiles can be used to monitor one instance. This way the probe can be configured to deploy available resources the best way and allows independent monitoring of several instances simultaneously. Icons in the profile list ■

Green icon indicates that the profile is active and running.

■

Yellow icon indicates that the profile is active but suspended .The Suspended /Resumed button in the profile properties dialog allows stopping / starting profile monitoring dynamic, without deactivating /activating the probe.

■

Black icon indicates that the profile is inactive.

You may add, edit delete and copy profiles.

22 db2 Guide

Probe Configuration

Edit Profile Dialog Right-click the profile and select Edit. The Edit Profile dialog opens to edit the profile properties. The upper part of the dialog displays general profile properties and defaults whereas the lower part provides a list of available checkpoints. The Suspended / Resumed commands allows stopping / starting profile monitoring dynamic without deactivating /activating the probe.

This dialog contains the following fields: Description Provides short description of the profile. Heartbeat Defines the interval at which all profile checkpoints schedules will be tested and trigger eventual checkpoint execution. This number should be common denominator to all used check interval values. The higher the value the lower is the profile overhead.


Probe Configuration

Connection Specifies the connection used in this profile. It has to be defined in Connections dialog before creating a profile. Check Interval Indicates the default value for check interval in the profile. This will be used if nothing else is defined in the checkpoint and overwrites the default checkpoint list setting. Clear message Specifies the message name for clear alarm. SQL Timeout Every checkpoint query run asynchronously. In case the query reaches the SQL timeout, the checkpoint processing will be terminated and the next checkpoint will be started. Alarm is issued. Message Specifies the message name used for SQL timeout alarm. Profile Timeout Defines the maximum processing time for all checkpoints in the profile. If this timeout is reached, the interval processing is finished and the probe waits for next heartbeat to evaluate any checkpoint schedules. Alarm message is issued. Message Specifies the message name used for profile timeout alarm. Timeout severity Defines severity for timeout messages. Suspended/Resumed (indicator) Indicates whether the profile is activated or not. This indicator is green when the profile is activated. The indicator changes to yellow when the profile is suspended and to black when deactivated. Alarm source Lets you override the source name of the alarm. If not used, default is assumed (robot IP). Profile checkpoints Provides the list of available checkpoints. When defining a new profile, all the available checkpoints (listed under the Checkpoints tab) will be listed here. Select the checkpoints you want for your new profile. The global and default checkpoint settings will be used unless you modify the settings locally for your profile (see section Checkpoints in Profile).

24 db2 Guide

Probe Configuration

Checkpoints in Profile After defining a profile, you can use two different strategies for handling checkpoints in a profile. You can decide to use checkpoint templates dynamic, which means that the checkpoints are defined globally (under the Templates tab) and represent the default settings. Every time you change the template value, it will reflect on all profiles using dynamic templates strategy. If you want to have specific settings valid just for one profile, you should right-click the checkpoint in the list and select Change to static.


Probe Configuration

Now you can double-click the checkpoint to modify the properties and the settings will be valid for this profile only. Note: If you attempt to modify a template checkpoint in the Profile dialog without changing it to static as described above, you will receive the following warning:

There can be both template and static checkpoints mixed in one profile. If a checkpoint is managed as static, the checkpoint name will appear in the list with a blue color and it will be marked as static in the column Type. Type of Checkpoints ■

Static: Manages the properties for a checkpoint locally. Change the checkpoint to static in your profile before modifying it. When modified, the new settings will be valid for this profile only.

■

Template: Edits the properties for a checkpoint template. Double-click the checkpoint in the profile list or Templates tab. When modified, the new settings will be valid for all profiles, unless overruled by static settings in the profile.

Refer the section Edit a Checkpoint (see page 38) for a description of the checkpoint properties. When deciding which checkpoints to activate/deactivate for a profile, refer section Checkpoint Metrics (see page 46) for a description of the different checkpoints.

26 db2 Guide

Probe Configuration

Templates Tab The Templates tab contains the list of predefined set of checkpoints that you may use in your profiles. These checkpoints can be modified to your preferences.

By default, most checkpoints are active with a reasonable default threshold value. The checkpoint properties may be used in a profile either dynamic, using the template values, or they can be added to the profile and managed static in the profile. Static Edits the properties for a checkpoint locally for a profile. Right-click the profile in the checkpoints list in the Edit Profile dialog and change it to static. Double-click the checkpoint to modify it. When modified, the new settings will be valid for this profile only. Template Edits the properties for a checkpoint template. Double-click the checkpoint in the checkpoints list in the Edit Profile dialog or Templates tab. When modified, the new settings will be valid for all profiles, unless overruled by static settings in the profile.


Probe Configuration

Define a New Checkpoint This functionality allows you to create a custom checkpoint for the DB2 probe. Follow these steps: 1.

In the Templates tab, right-click and select Create new from the context menu.

The Add New User Template dialog appears. 2.

Probe Configuration

General Tab

This tab contains the following fields: Description Provides short description of the purpose of the checkpoint. Active Allows to activate the checkpoint. Condition Provides information describing how the threshold values are evaluated. Check Interval Specifies the interval value used for this checkpoint. Every checkpoint can have a different check interval value. Default is taken from the profile definition, if not defined than from the default checkpoint list.

34 db2 Guide

Probe Configuration

Send Quality of Service Activates QoS values being send into the QoS database. If not available in a checkpoint, checkbox is disabled. QoS List Opens the QoS list showing the current QoS definitions (default is one definition per checkpoint). Right-clicking in the list lets you add new QoS definitions and copy, edit or delete an existing QoS definition. The Edit QoS dialog offers available metrics (numerical variables which could be reported as QoS) and available object variables (if any - to be added to the QoS source). The name of the QoS has to start with the checkpoint name. QoS can be activated/deactivated as usual. Note: Some of the checkpoints have no QoS possibilities - from these checkpoints the QoS dialog cannot be activated. Samples Saves the number of samples specified here and calculate an average value. This average value will be compared to the alarm threshold specified. Setting "Samples = 1", no sampling is done. Setting "Samples = 3", the average of the 3 last samples will be used. Setting "Samples = 0" (in profile), number of samples will be taken from the template. If not set there, no sampling is done. Initially after start-up, the probe calculates the average value from the number of samples available. Example, Samples=3: In the first interval the first sample value is used In the second interval, the average of sample 1 and 2 will be used etc. Note: Many checkpoints calculate an "interval value", therefore in the first interval there is no value at all (no threshold checking). Use excludes Provides the option to add excludes to the Excludes list to some of the checkpoints (as it does not make sense for all checkpoints). Using excludes, you can define objects that you do NOT want to monitor on the checkpoint. The excludes patterns found if clicking the Excludes list button will be used for the checkpoint.


Probe Configuration

Excludes list Opens the list that shows if excludes are defined for the checkpoint. The excludes found in the list will be used for the checkpoint if the Use excludes option is checked. Right-clicking in the list lets you add new excludes or edit, copy or delete existing excludes. When adding (or editing) an exclude pattern, a Match expression dialog is opened, letting you edit or define the exclude pattern. Excludes are defined using regular expression patterns. A test button lets you test the exclude pattern defined. This test is possible only for running active profiles and checkpoints. The test uses the status list (on the status tab) as input: Note: If there already are active excludes, the excluded objects are excluded from the status list BEFORE the test. When clicking the Test button, an Exclude test list pops up, showing the result of the test. Red text lines show the objects which would be excluded using the tested pattern. The "object thresholds" are functioning as an "include list". This means if there are special thresholds defined for a special object, this object will always stay in, even if the exclude pattern would eliminate it normally. This is considered also in the test function. Scheduling This field lets you select how to use the schedules settings, if any (see description below the table). rules Selecting rules means to run according the rules described in the Schedules settings. exceptions Selecting exceptions means to run except the rules described in the Schedules settings. Clear message Specifies the message name used for clear alarm message. Clear severity Severity used for message issued in normal state. Thresholds/Schedules Refer Thresholds (see page 42) and Schedules (see page 43).

Probe Configuration

Edit a Checkpoint The checkpoint properties may be used in a profile either dynamic, using the template values, or they can be added to the profile and managed static in the profile. Static Edits the properties for a checkpoint locally for a profile. Right-click the profile in the list of checkpoints in the Edit Profile dialog and change it to static. Double-click the checkpoint to modify it. When modified, the new settings will be valid for this profile only. Template Edits the properties for a checkpoint template. Double-click the checkpoint in the Edit Profile dialog or Templates tab. When modified, the new settings will be valid for all profiles, unless overruled by static settings in the profile. The properties for checkpoints are described below:

38 db2 Guide

Clear message Specifies the message name used for clear alarm message. Clear severity Severity used for message issued in normal state. Thresholds/Schedules Refer Thresholds (see page 42) and Schedules (see page 43).


Probe Configuration

Thresholds The list contains the predefined set of monitoring profiles that you may use in your profiles and that you can modify to your preferences. By default, most profiles are active with a reasonable default threshold value. The threshold values may be defined by modifying checkpoints in the respective profile. Every checkpoint has to have at least one threshold, but there can be additional thresholds defined. The threshold identification consists of an object name (if applicable), like tablespace name, userid etc. and a threshold ID, numbered from 0. Threshold values have to be descending or ascending, depending on condition used in a checkpoint, starting with the highest severity threshold condition.

This section contains the following fields: Threshold object name Indicates the monitoring object name, if applicable or default. Some special checkpoints have a second threshold called ‘count" (e.g. "locked_users"). Threshold value Specifies the value used for threshold evaluation. Current value If invoked from the status report, it contains the last measured value. Severity Specifies the alarm severity.

42 db2 Guide

Probe Configuration

Message Defines the name of message used for threshold alarm. Message text Displays the text of the message, containing variables, which will be replaced in run time. If the message text is changed from a profile list, you will be forced to create new message. Variables Lists variables available in the checkpoint.

Schedules If the schedules list is empty, the checkpoint will be executed on interval, 24 hours a day. You can also define several schedules per checkpoint, each defining additional rules to the check interval or exceptions of it. The rules and exceptions cannot be mixed in one checkpoint.

In principle, a schedule is a definition of an execution period (or execution break if exceptions used) with specified days, including time from/to and date from/to values. If only Date from and Time from is defined, first execution can be defined. Run once will cause the checkpoint run only once a day in the defined period (unlike multiple times if Run interval is used).


Probe Configuration

Status Tab The Status tab displays contents in a hierarchal fashion with the profile name nodes and one or more checkpoint nodes (only active checkpoints are considered here). The highest status is propagated. Select the checkpoint in the navigation tree (to your left) to bring up the corresponding events.

The properties for an individual checkpoint object can also be modified here. Select a profile and a monitored checkpoint in the left pane. Then double-click an object in the right pane. If the object belongs to a template object, you will be warned that a modification will make the checkpoint static for the selected profile.

Group Tab This tab lets you create multiple groups which can be associated with profiles.

You can add, copy, modify, or delete a group.

Checkpoints Metrics There are five kind of metrics used: Count Absolute number of events in the interval. It is calculated as delta between count at the beginning of the interval and at the end. In the first interval, counts are not checked because their interval value cannot be calculated. If there is a "total" value in the message, it means "since the start of the instance". Gauge Absolute number describing the actual state of the system. Ratio Calculated percentage using interval counts. In the first interval, it is calculated from total counts (as the interval count cannot be calculated). Average Calculated using interval counts. In the starting interval, it is calculated from absolute counts. Status Absolute value like ‘ONLINE’ etc.

Single Counter Description Most of the checkpoints are measuring single DB2 snapshot counter values. Description of these counters can be found in the IBM DB2 "System Monitor Guide and Reference" manual or in DB2 Information Center under "Monitor elements": http://publib.boulder.ibm.com/infocenter/db2luw/v9r5/index.jsp http://publib.boulder.ibm.com/infocenter/db2luw/v9r5/index.jsp The IBM used counter names are hierarchically organized and therefore not unique. For this reason, the probe is adding to every name a prefix, depending on its source: ■

"i_" for instance snapshot

■

"db_" for database

■

"bp_" for bufferpool

■

"app_" for application

■

"ts_" for tablespace statistics counter.

So the description for the counter "i_comm_private_mem" can be found under "comm_private_mem" in the IBM sources.

Chapter 4: QoS Threshold Metrics Many Nimsoft Monitor probes ship with default QoS threshold values set. The default threshold values provide an idea of the type of values to be entered in the fields and are not necessarily recommended best practice values. To aid in tuning thresholds and reducing false-positive alarms, this section describes the QoS metrics and provides the default QoS thresholds.

This section contains the following topics: db2 QoS Metrics (see page 53) db2 Alert Metrics Default Settings (see page 58)
