Problem Grafana about grafana-pnp-datasource HOT 13 CLOSED

Have you installed the pnp api extension as mentioned here in the Readme? Afaik it is still not included in the latest pnp4nagios release.

from grafana-pnp-datasource.

I just make:

wget "https://github.com/lingej/pnp-metrics-api/raw/master/application/controller/api.php"
-O /usr/local/pnp4nagios/share/application/controllers/api.php

restart all and still have problem:

from grafana-pnp-datasource.

If there is an internal server error, there should be something logged anywhere. Most probably in the apache error log

Meaby something is wrong here?

from grafana-pnp-datasource.

not really helpful. You could have a look at the chrome dev tools or the firefox web developer toolbar while testing the datasource and see if there are any hints in the response.

I found someting here

from grafana-pnp-datasource.

good, thats something to fix. Just make sure the api.php has the same permissions and owner/group as the other controller php files in that folder.

Done this:

But sill have something like:

from grafana-pnp-datasource.

here are some curl commands to manually test the api: https://github.com/lingej/pnp-metrics-api
Make sure the api works. Thats nothing this datasource can do about it.

Meaby problem is here?

I will try the curls commands

Same issue here. I think related to SELinux. Check /var/log/audit/audit.log

type=AVC msg=audit(1596038131.954:1851): avc:  denied  { getattr } for  pid=29839 comm="httpd" path="/usr/local/monitoring/addons/pnp/share/application/controllers/api.php" dev="dm-0" ino=74720090 scontext=system_u:system_r:httpd_t:s0 tcontext=unconfined_u:object_r:admin_home_t:s0 tclass=file permissive=0

from grafana-pnp-datasource.

In my case there were two roots for that problem, try to set selinux permissive (temporal solution) with

sudo setenforce 0

Consider that i'm using centOS 7

Also, I added a Require policy in /etc/httpd/conf.d/pnp4nagios.conf "Require host localhost"
