NAME

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

SYNOPSIS

       $PCP_PMDAS_DIR/linux_zfs/pmdazfs [-d domain] [-l logfile]

DESCRIPTION

       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.

INSTALLATION

       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
