NAME

pmdaunbound - Unbound resolver PMDA

DESCRIPTION

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/

INSTALLATION

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.
