Poller cache


The poller cache holds all the commands that Cacti will issue during the polling process in an internal format. To view this cache, open Cacti, and visit System Utilities.

Now, click on View Poller cache. From this page, you can also view the Cacti log, user log, SNMP cache, and rebuild the poller cache.

In this, you will get the list of poller cache. If you make any change to Cacti and the graphs stop updating, you need to rebuild the poller cache. To rebuild the poller cache, go to the previous page and click Rebuild Poller cache. If everything goes fine, you will get the same page shown in the above screenshot. Otherwise, it will show you an error.
