install-node-exporter

A task to add node exporter Param to DRP endpoint

This task installs the Node Exporter package on a given machine. It also will record the Node Exporter systems IP address in the param 'drp-prom-mon/node-exporter'. This value will subsequently be used by the Prometheus Stage to collect (scrape) metrics from this machine.

The Param 'drp-prom-mon/cluster-profile' MUST BE SET on the machine so that the Stage can record the Pram information correctly.

If the Param 'drp-prom-mon/cluster-profile' is set to the value

::

prom-mon-single-node

Then the Stage will assume this is an all-in-one DRP/Prometheus/ Node Exporter/Grafana platform - and you DO NOT have to set the cluster profile.
