Nagios Support Forum

i'm running nagios 3.4.1 and get nice graphs when surfing to localhost/pnp4nagios.
on a different machine in a similar environment, i'm running 3.5.1. i copied the cfg files
which changes where appropriate. localhost/pnp4nagios gives a blank page.
any suggestions which specific cfg file to look at? npcd is running on both machines.
the pnp4nagios log file didn't give help me much.

tnx,
ams

Can you browse to one of those broken pages and then post a tail of the apache error log in code wraps:

the indicated files really don't exist. it's not a permission issue.
the forum didn't let me post what u requested.
complained "too many url's. max. of 10 permited".
here's the last few lines of the output:
/var/log/apache2 $ tail -f !$
tail -f error.log

Did you install PNP4Nagios on the 3.5.1 server? Or did you just copy the files there?

i just copied the files. figured that it'll save me the trouble of configuring again.
this is balanced against the risk that i miss a file here or there.

Provided you install to the same locations, you should be able to bring your config over. Based on your logs, it looks like either a few files or directories are either missing or have incorrect permissions. Try:

yes! a fresh (real) install of pnp4nagios solved the problem.
tnx guys,
