Cacti Apache CPU load

Hello,

I’ve installed Percona monitoring plugins for Cacti/apache and all graphs are displaying graphs except for Apache CPU load. I have this for couple of servers and on all only this graph is not being populated, showing Cur: 0.0 Avg: 0.0 Max: 0.0. But on all servers there are active apache processes and usage.

Any idea what is wrong and how to fix it would be appreciated.

Regards,

Zeljko
