Nagios Support Forum

Hello,

I've installed Nagios Core 4.2.2 and Nagiosgraph 1.5.2 on CentOS 7.0 64bit. Both Nagios Core and Nagiosgraph was installed from source.

The check-host-alive graph isn't updating for any hosts. The RRD files gets created for every host and gets updated continually but nothing shows on the graph itself.
Any other service is updating in Nagiosgraph. It's just check-host-alive that is not working.

Please see attached config files and screenshots. If anyone can assist me with this please.

Do I need to use the latest version of nagiosgraph? Is this possibly why I'm having problems.

Could you also post the results of tail -f /var/log/httpd/error_log? Thanks!

If your httpd error logs are elsewhere, post those instead.

Hi,

Here is the http error_log

This is going to take us a little while to troubleshoot, since Nagiosgraph is not our product. Have you posted in the Nagiosgraph forums at https://sourceforge.net/p/nagiosgraph/d ... on/394748/ ? If so, could you like to that thread? Thanks!

Hi,

I couldn't find a support forum for nagiosgraph. I just posted a question there as well in connection with this problem.
I'll see if someone there can assist me.

Thank you,

Definitely let us know if you find a fix. Also, have you thought about other graphing frontends like PNP4Nagios?

Hi,

So far no-one has answered me on sourceforge. I haven't found the solution either.

I did however install and configure pnp4nagios and it's working perfect. Check-host-alive is updating on this frontend.

Thanks a bunch

Glad you have a solution that works for you! Is it okay if we lock this thread? We can let someone else open their own thread if they want to stick it out with nagiosgraph instead of using PNP4Nagios.

Thanks for choosing the Nagios forums!

I had the same issue, probably for as long as I can remember; but I never seemed to care/need that data till now. It turned out to be that I had decided (not sure how, been too long) not to originally include the "host_perfdata_file" settings in my nagios.cfg

After that, restart, and it started creating that file.

@AGray, for clarity you resolved this issue and are just trying to help out @Asjas, correct?

If so, thanks!

If not, could you rephrase your problem? Thanks!
