Configuring application monitoring on a single-node cluster

The ConfigAppMonHB utility lets you configure HA for applications in single-node cluster deployments, which includes the application service groups and the AppMonHB agent resources.

Prerequisites

At the vCenter level, make sure that:

  • The vSphere HA > VM Monitoring > VM and Application Monitoring options are enabled.

  • At least one heartbeat datastore is configured for vSphere HA.

To configure application monitoring on a single-node cluster

  1. Use either one of the following ways to invoke the ConfigAppMonHB.pl utility (default location: %vcs_home%\bin\AppMonHB\):

    • Navigate to the AppMonHB directory and run:

      C:\Program Files\Veritas\clusterserver\bin\AppMonHB>"C:\Program Files\Veritas\VRTSPerl\bin\perl.exe" ConfigAppMonHB.pl

    • Navigate to the VRTSPerl directory and run:

      C:\Program Files\Veritas\VRTSPerl\bin>perl.exe "C:\Program Files\Veritas\cluster server\bin\AppMonHB\ConfigAppMonHB.pl"

  2. When prompted, enter E as the option to enable application monitoring on the node.

To configure monitoring for all the service groups in the cluster

  • When prompted, enter A to enable application monitoring for all the service groups configured on the node.

    If any required groups or resources are not present in the local cluster, the utility prompts you for further action:

    • To append the missing entities to the existing service groups in the cluster, enter A.

    • To add the missing entities as per your preference and reset the cluster, enter R.

To configure monitoring only for specific service groups in the cluster

  1. When prompted, enter S to enable application monitoring for a selective set of service groups configured on the node.

    Note:

    You can also use this option to selectively discontinue monitoring the application service groups that you specify.

  2. When prompted, enter the names of only those service groups that you want to monitor, separated by spaces; for example, SG1 SG2 SG3.

    The utility repeats the names of the service groups that you specified and then displays the names of the service groups that may have already been configured for monitoring.

  3. When prompted, specify your preference:

    • To append to the list of existing service groups being monitored, enter A.

    • To reset the configuration and monitor only those service groups that you specified in the previous step, enter R.

To specify the duration after which corrective action is taken

  • When the utility prompts you to update the WaitBeforeCorrectiveAction duration:

    • To use the default value of 300 seconds, enter N.

    • To specify a custom value, enter Y.

      When prompted, enter the value in seconds, for example 30.

    Alternatively, you can change the duration by running the following sequence of commands on the node at any later time:

    # haconf -makerw

    # hares -modify VCSAppMonRes WaitBeforeCorrectiveAction <integer value in seconds>

    # haconf -dump -makero
