pmdalustre — lustre filesystem statistics performance metrics domain agent (PMDA)

Description

pmdalustre is a Performance Metrics Domain Agent (PMDA) which exports metric values from the /proc/fs/lustre and /proc/sys/lnet trees to provide information on mounted lustre filesystems.

Installation

Install the lustre PMDA by using the Install script as root:

# cd $PCP_PMDAS_DIR/lustre
# ./Install

To uninstall, do the following as root:

# cd $PCP_PMDAS_DIR/lustre
# ./Remove

pmdalustre 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.

PCP Environment

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 configuration file, as described in pcp.conf(5).
