Unpack downloaded archive.
Save ss_poller.php to the ./scripts directory of your cacti installation. Then import the Host Template; it includes only the graph templates described below.
In alphabetical order of appearance:
Memory Usage of the boost process. The statistics are updated after each boost run, depending on your local settings for BOOST.
Shows the total runtime of the boost process.
Shows the number of RRD Updates performed by Boost.
Number of Data Sources handled by the Cacti Poller Process. When not using BOOST, the number of RRDs will show up. When using BOOST, the number of RRDs will always be 0 because the poller itself does not perform the updates anymore. See Boost statistics above for the number of rrd updates, then.
The number of polled hosts, hosts per polling process (spine only), number of data sources (same as above) and number of rrd files updated (when not using boost).
Show the number of Scripts, Script Server Scripts and SNMP Items that are queried by the poller. This information is useful when searching for performance bottlenecks. SNMP items are fastest.
In case cacti discovers a recache event (e.g. number of interfaces changed), this graph will show the effect: Number of recaching events and recache runtime is shown here.
Perhaps the most wanted information: How long does the cacti poller run!
