pmdaunbound - Man Page

pmdaunbound is a Performance Metrics Domain Agent (PMDA) which exports metric values about the Unbound DNS resolver using the unbound-control(8) stats_noreset command.

This gives lots of insight into query types, response time, cache hits/misses, etc. Please see the unbound-control(8) man page for explanation about each statistics counter.

Further details on the Unbound DNS resolver can be found at https://unbound.net/.

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

# cd $PCP_PMDAS_DIR/unbound
# ./Install

To uninstall, do the following as root:

# cd $PCP_PMDAS_DIR/unbound
# ./Remove

pmdaunbound 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.

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).
