Re: [opsview-users] MRTG High Server Load

[Jacob d'Andrade]

Hello

 

I’m seeing a similar problem with my Opsview installation, after upgrading to 
3.7.0… MRTG hogs a lot of cpu time, and I’m unable to view the graphs…

I just rebooted the server yesterday after the upgrade, at the moment I have 
six processes named mrtg-rrd.cgi running, taking up all available cpu time… How 
can this be?

 

Kind regards Jacob

Hi @ all!

 

 

 

I´ve got the problem that our Monitoring-Server have a high load caused by 
MRTG.

Any ideas what i can do?

 

Another problem is that Opsview start a new process of “mrtgconfgen”, already 
if the old one is active. If I don´t kill the process manually our monitoring 
server will have a load from 20 after 2 days.

 

 

 

 

 

Best Regards,
