Enabling in-depth monitoring from the command line for DB2

You can dynamically configure in-depth monitoring. Arctera recommends that you successfully run DB2 with the agent's default (shallow) monitoring before you start the in-depth monitoring. In the MPP configuration, make sure the database can be accessed locally by the database partition.

Copy the required custom monitoring scripts from /etc/VRTSagents/ha/conf/Db2udb/sample_db2udb to /opt/VRTSagents/ha/bin/Db2udb.

In case of a single-node cluster configuration, make sure to copy the monitor_custom_db2inst1_0 script and set its file permissions to 755 by using the following command:

# chmod 755 /opt/VRTSagents/ha/bin/Db2udb/monitor_custom_db2inst1_0

See About the Db2udb resource types and attribute definitions.

To start the in-depth monitor for a given instance

  1. Make the VCS configuration writable:
    # haconf -makerw
  2. Freeze the service group so VCS does not perform actions automatically based on an incomplete reconfiguration:
    # hagrp -freeze db2udb_group
  3. Enable in-depth monitoring using the command:
    # hares -modify resource DatabaseName name

    # hares -modify resource IndepthMonitor 1

    For example:

    # hares -modify db2udb DatabaseName SAMPLE
# hares -modify db2udb IndepthMonitor 1
# haconf -dump -makero
# hagrp -unfreeze db2udb_group
