Configure Veritas File System KM

Monitoring Mode

By default, Veritas File System KM is configured to operate in Single-node Mode. In a cluster environment, i.e. active on one cluster node and passive on others, false alarms and duplicate alerts may occur. To avoid such a situation, you need to switch to Multi-node Mode, if you monitor Veritas File System KM from cluster nodes.

1. Click the Single-node Mode button to switch to Multi-node Mode
2. Select the appropriate Cluster Application and provide the Failover Group Name which is online on one cluster node and offline on the others. Leave this field blank if you previously selected Veritas Cluster File System. The Veritas File System KM will then monitor the entire cluster from the active system, which is identified by the vxdctl -c mode command. This method requires vxconfigd in enable mode with its clustered state active
3. Click the ADD NODE button to individually add the nodes you wish to monitor. Provide the following information:
   • PATROL Agent Hostname: the host from where this node is monitored
   • Node ID: the internal ID specified for the VxFS node
   • Cluster Node Name: the hostname defined in the selected Cluster Application.

Click the Multi-node Mode button to switch back to Single-node Mode.

VxFS Discovery

Veritas File System KM automatically discovers the application paths and the node type and the default values are set to comply with most of VxFS systems. However, you can customize these settings to better suit your requirements. Note that modifying discovery configurations should be used with caution as it affects the monitoring functionality.

To configure the VxFS Discovery settings, click the Automatic button to turn on the Custom mode and provide the following information:

• VxFS Installation Path: Provide the path to the directory where the VxFS software is installed. By default, Veritas File System KM automatically locates the VxFS software installation directory if you have installed the solution with the default recommended settings. If you have chosen to install the solution in a custom directory, you are required to provide its location.

Click the CUSTOM button to switch back to AUTOMATIC mode and discard all custom settings.

Remote Connection settings

When you configure the monitoring of a remote host, you may want to specify the time after which the connection to the remote node will time out or the maximum number of simultaneous connections allowed to the remote node:

• In the Connection Timeout field, enter the number of seconds after which the connection to the remote node will time out
• In the Maximum Connections field, enter the maximum number of simultaneous connections allowed to the remote node.

Important: Changing the values for these properties may impact the performance of your monitoring environment.

VxFS KM Temp Paths

The default VxFS KM temporary directory paths can be manually specified to better suit your requirements.

Click the DEFAULT button to switch to the CUSTOM mode and provide the following information:

• Remote Temp Directory Path: Provide the path to the directory where the temporary files are saved on remote nodes. Default is /var/tmp (on UNIX/Linux) or C:\Windows\Temp (on Windows).
• Local Temp Directory Path: Provide the path to the directory where the temporary files are saved on the PATROL Agent node (Default is <PATROL_HOME>/lib/VFS/tmp where <PATROL_HOME> is the PATROL Agent installation path)

Click the CUSTOM button to switch back to the DEFAULT mode and reset all paths to their default settings.
