[Pdns-users] PowerDNS Monitoring and gathering Statistics

We use Zenoss open source version. Then on the server I created a snmpd.local.conf file that has the following:

exec all-outqueries      /opt/snmp-scripts/recursor_stats all-outqueries
exec cache-entries       /opt/snmp-scripts/recursor_stats cache-entries
exec cache-hits          /opt/snmp-scripts/recursor_stats cache-hits

etc, etc.

The recursor_stats script is used for older version that are not fully multithreaded. Here is what it looks like:

#Pull pdns_recursor stats for use via Zenoss
#On the servers running pdns_recursor, we have four processes running, two for each
if [ -e $PIDFILEONE ]; then
        for PID in `cat $PIDFILEONE`; do
                PDNSCOUNTONE=`/usr/bin/rec_control --socket-dir=/var/run/recursor1/ --socket-pid=$PID get $1`
if [ -e $PDFILETWO ]; then
        for PID in `cat $PIDFILETWO`; do
                PDNSCOUNTTWO=`/usr/bin/rec_control --socket-dir=/var/run/recursor2/ --socket-pid=$PID get $1`

We run 2 daemons each with set with --fork so we have to do a count of all the daemons.

Then in Zenoss we use the OID of,, to pull these.
