What David said!

A couple of additional thoughts:

o Nagios (and derivatives like Icinga and check_mk) have been popular for years.  \
Note that they're monitoring solutions vs metrics solutions — it's good to have \
both.  One issue I've seen multiple times with Nagios-family monitoring is that over \
time as checks and the fleet grow, the server tends to bog down, and the litany of \
active checks starts taking longer to run than the check interval.  Prometheus \
alertmanager is more scalable, and with some thought most active checks can be recast \
in terms of metrics.

o Prometheus (forked node_exporter) was INVALUABLE to me when characterizing and \
engaging two seperate SSD firmware design flaw issues. It includes a data query \
interface for ad-hoc queries and expression development

o Grafana pairs well with Prometheus for dashboard-style visualization and trending \
across many clusters / nodes
