DB2 Monitoring Subagent

Summary
NetXMS subagent for DB2 monitoring is designed to provide a way to extract various parameters known as Data Collection Items (DCI) from an instance or several instances of DB2 database.
Configuration
DB2 subagent can be configured in two ways. The first one would be a simple INI file and the second one would be an XML configuration file. Please note that to use the XML configuration, you first need to declare the XML file in the DB2 section of the INI configuration file. The details are below.
INI configuration
The configuration section in INI file looks like the following:
SubAgent = db2.nsm
*DB2
DBName = dbname
DBAlias = dbalias
UserName = dbuser
Password = mypass123
QueryInterval = 60
ReconnectInterval = 30
| Parameter | Format | Description | Default Value |
|---|---|---|---|
| DBName | string | The name of the database to connect to | - |
| DBAlias | string | The alias of the database to connect to | - |
| UserName | string | The name of the user for the database to connect to | - |
| Password | string | The password for the database to connect to | - |
| EncryptedPassword | string | The encrypted password for the database to connect to (use nxencpasswd for encryption) | - |
| QueryInterval | milliseconds | The interval to perform queries with | 60 |
| ReconnectInterval | milliseconds | The interval to try to reconnect to the database if the connection was lost or could not be established | 30 |
XML configuration
XML configuration allows the monitoring of several database instances.
To be able to use the XML configuration file, you first need to specify the file to use in the DB2 section of the INI file. The syntax is as follows:
SubAgent = db2.nsm
*DB2
ConfigFile = /myhome/configs/db2.xml
Note that all other entries in the DB2 will be ignored.
| Parameter | Format | Description | Default Value |
|---|---|---|---|
| ConfigFile | string | The path to the XML configuration file | - |
The XML configuration file itself should look like this:
<config>
<db2sub>
<db2 id="1">
<dbname>dbname</dbname>
<dbalias>dbalias</dbalias>
<username>dbuser</username>
<password>mypass123</password>
<queryinterval>60</queryinterval>
<reconnectinterval>30</reconnectinterval>
</db2>
<db2 id="2">
<dbname>dbname1</dbname>
<dbalias>dbalias1</dbalias>
<username>dbuser1</username>
<password>mypass456</password>
<queryinterval>60</queryinterval>
<reconnectinterval>30</reconnectinterval>
</db2>
</db2sub>
</config>
As you can see, the parameters are the same as the ones from the INI configuration.
Each database declaration must be placed in the db2sub tag and enclosed in the db2 tag. The db2 tag must have a numerical id which has to be a positive integer greater than 0.
Provided parameters
To get a DCI from the subagent, you need to specify the id from the db2 entry in the XML configuration file (in case of INI configuration, the id will be 1). To specify the id, you need to add it enclosed in brackets to the name of the parameter that is being requested (e.g., db2.parameter.to.request(1)). In the example, the parameter db2.parameter.to.request from the database with the id 1 will be returned.
