Installation of Performance Monitoring tool using the installation toolkit

By default, the Performance Monitoring tool gets installed when IBM Spectrum Scale™ is installed on the system using the ./spectrumscale install command.

For more information on the Performance Monitoring tool, see Performance Monitoring tool overview in IBM Spectrum Scale: Advanced Administration Guide.

The following configuration occurs on the system after the installation:

Sensors are installed and started on every node.
The collector is installed and configured on two nodes in all cases apart from the following:
- One node if there is a one-node cluster.
- Three nodes when there are three GUI servers specified in the cluster definition.
The proxies for the installed protocols are started. In the case of NFS and SMB, the proxy is installed with the code. In the case of object it is installed as a separate step as the final part of the installation.

During the install toolkit prechecks if is it found that the collector nodes require reconfiguring then the ./spectrumscale config perfmon -r on CLI will need to be run to enable the install toolkit to perform this reconfiguration.

Note: A reconfiguration will result in the removal of an existing collector. To disable reconfigure run the ./spectrumscale config perfmon -r off command:

usage: spectrumscale config perfmon [-h] [-l] [-r {on,off}]

Optional arguments:

-h: --help show this help message and exit
-l: --list List the current settings in the configuration
-r {on,off}: --enable-reconfig {on,off}

Specify if the install toolkit can reconfigure Performance Monitoring.

If reconfigure is disabled then the install toolkit will perform all installation tasks minus Performance Monitoring and the Graphical User Interface (GUI) if GUI servers are specified.
