The update script needs to be run at exactly the same interval as defined in your database.I see it has a step value of 300 so the database should be updated every 5 minutes.
Hi Everyone, I am new to cacti and I have been trying to setup my first cacti for almost 2 days now and with no avail.
I tried several manuals which is available online but I always end up the same problem.
Until you have enough data to write a CDP, you have nothing to graph, and your graph will always have unknown data.
Alternatively, add a smaller resolution RRA (maybe Count 1) so that you do not need to collect data for so long before you have a full CDP.
The cronjob calls the cacti poller to start performing it's polling cycle.
