NAME
pmdagluster - Gluster Filesystem PMDA DESCRIPTION
pmdagluster is a Performance Metrics Domain Agent (PMDA) which exports metric values about mounted gluster filesystems using the gluster(8) command. This PMDA exports metrics about volumes and bricks both local and remote to the node where pmdagluster is running. The gluster filesystem supports fine-grained control over enabling statistics on individual volumes, so that the values are optionally enabled or disabled on systems where they are not desired to be monitored. The pmstore(1) command can be used to enable and disable profiling of volumes. Using the individual instances of the gluster.volume.pro- file metric, one can set their values (and associated profiling) either on (1) or off (0). Additionally, pminfo(1) can report on the cur- rent status of profiling of each volume. # pminfo -f gluster.volume.profile gluster.volume.profile inst [0 or "gv0"] value 0 inst [1 or "gv1"] value 1 # pmstore -i "gv0" gluster.volume.profile 1 gluster.volume.profile inst [0 or "gv0"] old value=0 new value=1 Further details on the gluster filesystem can be found at http://www.gluster.org INSTALLATION
Install the gluster PMDA by using the Install script as root: # cd $PCP_PMDAS_DIR/gluster # ./Install To uninstall, do the following as root: # cd $PCP_PMDAS_DIR/gluster # ./Remove pmdagluster is launched by pmcd(1) and should never be executed directly. The Install and Remove scripts notify pmcd(1) when the agent is installed or removed. FILES

Environment variables with the prefix PCP_ are used to parameterize the file and directory names used by PCP. On each installation, the file /etc/pcp.conf contains the local values for these variables. The $PCP_CONF variable may be used to specify an alternative configura- tion file, as described in pcp.conf(5). SEE ALSO

NAME
pmdalustrecomm - Lustre filesystem comms performance metrics domain agent (PMDA) SYNOPSIS
$PCP_PMDAS_DIR/lustrecomm/pmdalustrecomm [-d domain] [-l logfile] [-U username] DESCRIPTION
pmdalustrecomm is a Performance Metrics Domain Agent (PMDA) which extracts performance metrics from the Linux procfs filesystem about the state of various aspects of the Lustre filesystem. The lustrecomm PMDA exports metrics that focus on distributed communication in the filesystem, including metrics related to timeouts, net- work drops, send/recv information and route lengths. However, it also covers the memory use of some of the Lustre filesystem components. A brief description of the pmdalustrecomm command line options follows: -d It is absolutely crucial that the performance metrics domain number specified here is unique and consistent. That is, domain should be different for every PMDA on the one host, and the same domain number should be used for the same PMDA on all hosts. -l Location of the log file. By default, a log file named lustrecomm.log is written in the current directory of pmcd(1) when pmdalus- trecomm 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. -U User account under which to run the agent. The default is the unprivileged "pcp" account in current versions of PCP, but in older versions the superuser account ("root") was used by default. INSTALLATION
If you want access to the names, help text and values for the lustrecomm performance metrics, do the following as root: # cd $PCP_PMDAS_DIR/lustrecomm # ./Install If you want to undo the installation, do the following as root: # cd $PCP_PMDAS_DIR/lustrecomm # ./Remove pmdalustrecomm is launched by pmcd(1) and should never be executed directly. The Install and Remove scripts notify pmcd(1) when the agent is installed or removed. FILES

Environment variables with the prefix PCP_ are used to parameterize the file and directory names used by PCP.
