NAME

6       pmdazfs  -  ZFS  filesystem performance metrics domain agent (PMDA) for
7       Linux
8

SYNOPSIS

10       $PCP_PMDAS_DIR/linux_zfs/pmdazfs [-d domain] [-l logfile]
11

DESCRIPTION

13       pmdazfs is a Performance Metrics Domain  Agent  (PMDA)  which  extracts
14       performance metrics describing the state of the ZFS filesystem from the
15       stats files located in /proc.
16
17       The zfs PMDA exports metrics that  measure  information  about  caching
18       (ARC,  L2ARC,  ZIL, VDEV), buffering, RAIDZ, dnode operations and pools
19       IO.
20
21       A brief description of the pmdazfs command line options follows:
22
23       -d   The performance metrics domain number must  be  set  to  a  unique
24            value.
25
26       -l   Location of the log file.  By default, a log file named zfs.log is
27            written in the  current  directory  of  pmcd(1)  when  pmdazfs  is
28            started,  i.e.  $PCP_LOG_DIR/pmcd.  If the log file cannot be cre‐
29            ated or is not writable, output is written to the  standard  error
30            instead.

INSTALLATION

33       OpenZFS  is  not included in PCP, and has to be installed on the system
34       from the available packages or source.  Once OpenZFS is  installed  and
35       configured,  the  stats  files  should  appear in /proc and PMDA can be
36       added to PMCD using the Install script:
37
38            # cd $PCP_PMDAS_DIR/zfs
39            # ./Install
40
41       To remove PMDA use the Remove script:
42
43            # cd $PCP_PMDAS_DIR/zfs
44            # ./Remove
45
