DESCRIPTION

The glmstat command displays statistics about cluster-wide locks managed by the Group Lock Manager and GLM memory usage.

The statistics are based on counters kept in the kernel. These counters are not incremented until statistics gathering is explicitly enabled with the -e option.

NOTES

The glmstat command is intended primarily for troubleshooting and performance tuning by Veritas personnel. The glmstat command’s functionality and output are subject to change.

-d Disable the gathering of statistics. The value of the counters stops changing, but the counters are not cleared.
