Hi, Currently, the Icinga Web 2 Module for PNP seems to work only when having the PNP software on the same server. It would be nice to be able to have PNP running on a different server, for exemple in a clustered Icinga2/Icingaweb2 environment. Best regards, Yannick

Hello, you can change the base_url at /etc/icingaweb2/modules/pnp4nagios/config.ini:

[pnp4nagios]
config_dir = "/etc/pnp4nagios"
base_url = "https://monitoring.domain.tld/pnp4nagios"

and hack, if you like your apache config with a rewrite rule for the other server (here as https reverse proxy):

SSLProxyEngine On
ProxyPass /pnp4nagios https://pnpserver.domain2.tld/pnp4nagios
ProxyPassReverse /pnp4nagios https://pnpserver.domain2.tld/pnp4nagios

Now you can reach your pnp4nagios with https://monitoring.domain.tld/pnp4nagios (your default icingaweb2 server), but the source is https://pnpserver.domain2.tld/pnp4nagios (your pnp server)

This would need updated methods to check if there is actually performance data in PNP.

Currently the module accesses the XML files locally. Could we do this by HTTP?

Unfortunately there's no http api. There is a draft somewhere which exposes metrics for the Grafana data fetcher, but I doubt it has been released or merged yet. I don't think that it exposes everything you need from the XMLs too.
