PNP Grafana Datasource - a Grafana backend datasource using PNP4Nagios to access RRD files
pnp in the Grafana plugins directory or simply use the grafana-cli command:
grafana-cli plugins install sni-pnp-datasource
Also OMD-Labs comes with this datasource included, so if you use OMD-Labs, everything is setup already.
Otherwise follow these steps:
%> cd var/grafana/plugins %> git clone https://github.com/sni/grafana-pnp-datasource.git %> restart grafana
In order to make this datasource work, you need the pnp api. This is a separate
project at the moment and will be part of the official pnp in the future. You
can fetch the
api.php from https://github.com/lingej/pnp-metrics-api and place
it in your controler folder.
In a standard PNP setup, you could basically just download the api directly into the controller folder with a simple wget:
wget "https://github.com/lingej/pnp-metrics-api/raw/master/application/controller/api.php" \ -O /usr/share/pnp4nagios/html/application/controllers/api.php
Adjust the output path to your installation.
Direct access and proxy datasources are possible. Add a new datasource and select:
Uses the Grafana proxy. Must have a local user which is used for all queries.
- Type 'PNP' - Url 'https://localhost/sitename/pnp4nagios' - Access 'proxy' - Basic Auth 'True' - User + Password for local pnp user
Uses direct access. PNP must be accessible from the public.
- Type 'PNP' - Url 'https://yourhost/sitename/pnp4nagios' (Note: this has to be the absolute url) - Access 'direct' - Http Auth 'With Credentials'
This datasource ships an example dashboard which gets you started and shows the internal PNP statistics.
Simply select host, service and label in the query editor. Regular expressions
are supported in the host and service field by adding slashes like
You may use the following variables in the alias field
- $tag_host: will be replaced with the hostname - $tag_service: will be replaced with the service name - $tag_label: will be replaced with the label
There is basic templating variable support. There are 3 different querys available:
- $host: hosts - $service: services where host = /^$host$/ - $label: labels where host = /^$host$/ and service = /^$service$/
The easiest way to setup a test environment is to install the latest omd-labs package and
clone this repository to to
~/var/grafana/plugins. Make sure there is only one pnp
datasource, so you might have to remove the shiped one.
grunt watch and eventually restart Grafana after doing changes.
