By skyforbes Greetings,
Over 20 years ago (man I feel old), I had set up SNMP on Linux with Nagios and RRDTool.
While SNMP is hardly used anymore on Linux it had a lot of metrics that it collected, which was super useful for sending stats to either Nagios or RRDTool at the time.
Is there anything else out of the box that has a large set of monitors on Linux?
What are your favourite out-of-the-box Linux metrics collection tools?
