Cacti: PowerDNS Recursor Templates Rumi, September 11, 2011 Here are a couple of graph templates for the PowerDNS recursor. They need a shell script to be installed on the DNS server, and an net-snmp config change. Add the following to the snmpd.conf extend pdns-rec /usr/local/bin/pdns_stats.sh Put pdns_stats in /usr/local/bin, so that snmpd can find it (rename from pdns_stats.txt). Make it executable. Then import the templates. You end up with two graphs – one showing queries/sec + cache efficiency, and another one showing "exceptions" – slow queries, resource limits hit, spoof detection, etc. Update You can use the existing templates with the new script, but the new version also allows you to use a couple more templates, which I've attached below. These are 'Performance' which shows the proportion of queries answered in particular time bands, and 'Concurrency' which shows the number of threads running.
