pmdazfs - ZFS filesystem performance metrics domain agent (PMDA) for Linux

pmdazfs  is  a  Performance Metrics Domain Agent (PMDA) which extracts performance metrics describing the
       state of the ZFS filesystem from the stats files located in /proc.

       The zfs PMDA exports metrics that measure information about caching (ARC, L2ARC, ZIL,  VDEV),  buffering,
       RAIDZ, dnode operations and pools IO.

       A brief description of the pmdazfs command line options follows:

       -d   The performance metrics domain number must be set to a unique value.

       -l   Location  of the log file.  By default, a log file named zfs.log is written in the current directory
            of pmcd(1) when pmdazfs is started, i.e.  $PCP_LOG_DIR/pmcd.  If the log file cannot be  created  or
            is not writable, output is written to the standard error instead.

       OpenZFS  is  not  included  in  PCP, and has to be installed on the system from the available packages or
       source.  Once OpenZFS is installed and configured, the stats files should appear in /proc and PMDA can be
       added to PMCD using the Install script:

            # cd $PCP_PMDAS_DIR/zfs
            # ./Install

       To remove PMDA use the Remove script:

            # cd $PCP_PMDAS_DIR/zfs
            # ./Remove
