Имя (Name)
pmdazfs - ZFS filesystem performance metrics domain agent (PMDA)
for Linux
Синопсис (Synopsis)
$PCP_PMDAS_DIR/linux_zfs/pmdazfs [-d domain] [-l logfile]
Описание (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.
Установка (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
