Nagios Support Forum

nagiosgraph was last updated 2015-08-31 and PHP 7 came out 3 December 2015, so I think there are likely to be some compatibility issues there. Likewise, the last update to pnp4nagios was 2015-01-03.

Unfortunately, upgrading nagiosgraph and pnp4nagios is outside the scope of support, but of course a community member could step in and help out.

Are you trying to graph performance data? If so, I would take a look at https://assets.nagios.com/downloads/nag ... fdata.html

I successfully installed MRTG. I found a bug in cron.
But the graph does not correspond with my idea.
I will go through cron + php + mysql + js
Thans for all advice

You're welcome, we'll leave this thread open awhile longer in case you have any other graphing questions.
