Activate AFM performance monitoring sensors
The activated AFM performance monitoring sensor's DMP assists to activate the inactive AFM sensors.
The following are the corresponding event details and the proposed solution:
- Event ID: afm_sensors_inactive
- Problem: The AFM performance cannot be monitored because one or more of the performance
sensors like
GPFSAFMFS,GPFSAFMFSET, andGPFSAFMare offline. - Solution: Activate the AFM sensors.
The DMP provides the option to activate the AFM monitoring sensor and select a data collection interval that defines how frequently the sensors must collect data. It is recommended to select a value that is greater than or equal to 10 as the data collection frequency to reduce the impact on the system performance.
The system issues the mmperfmon command to activate AFM sensors as given in
the following format:
/usr/lpp/mmfs/bin/mmperfmon config update <<sensor_name>>.restrict=<<afm_gateway_nodes>>
/usr/lpp/mmfs/bin/mmperfmon config update <<sensor_name>>.period=<<seconds>>For example,
/usr/lpp/mmfs/bin/mmperfmon config update GPFSAFM.restrict=gss-41
/usr/lpp/mmfs/bin/mmperfmon config update GPFSAFM.period=30
