NAME         top

       pmdaunbound - Unbound resolver PMDA

DESCRIPTION         top

       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 .

INSTALLATION         top

       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
