Configuring the sensor

Performance monitoring sensors can either be managed manually as individual files on each node or managed automatically by IBM Spectrum Scale. Starting with IBM Spectrum Scale version 5.0.0, only IBM Spectrum Scale-managed sensor configuration is actively supported.

Identifying the type of configuration in use
If the performance monitoring infrastructure was installed previously, you might need to identify the type of configuration the system is currently using.
Automated configuration
Starting with version 4.2 of the performance monitoring tool, sensors can be configured on nodes that are part of an IBM Spectrum Scale cluster through an IBM Spectrum Scale based configuration mechanism. However, this requires the installation of IBM Spectrum Scale 4.2 or later versions on all the nodes where a sensor is running and where the sensors are to be configured. It also requires the entire cluster to be at least running IBM Spectrum Scale 4.1.1 or later version, and the execution of the mmchconfig release=LATEST command.
Manual configuration
Performance monitoring tools can also be configured manually by the user.
Adding or removing a sensor from an existing automated configuration
The performance monitoring system can be configured manually or through an automated process. To add a set of sensors for an automatic configuration, generate a file containing the sensors and the configuration parameters to be used.
Automatic assignment of single node sensors
A single node is automatically selected by the system to run the GPFSFilesetQuota, GPFSFileset, GPFSPool, and GPFSDiskCap sensors. If the selected node becomes unresponsive, the system reconfigures a healthy node to act as the singleton sensor node.
