Custom monitors
You can use the CLI to create custom monitors to collect and display selected statistics for selected targets.
See Monitor performance using the CLI.
Perpetual monitors
GeoSynchrony includes perpetual monitors that gather a standard set of performance statistics every 30 seconds. Perpetual
monitors collect the statistics related to the performance of metro node directors and virtual volumes.
Perpetual monitor files are collected as part of collect-diagnostics. Collect-diagnostics is per cluster, so in Metro
configurations, run the command from both metro node management servers.
Output of perpetual monitors is captured in the file smsDump_date.zip inside the base collect-diagnostics zip file.
Within smsDump_date.zip file, monitor files are in clilogs/.
You can also copy the perpetual files from the management server. They are located in /var/log/VPlex/cli/. There is one
perpetual monitor file per director, identifiable by the keyword “PERPETUAL” .
The following is an example for the statistics that perpetual monitors collect on virtual volumes:
