Hi, In case you mist my earlier reply (lost at the bottom of an old thread in your email client :-) ) I repost it like this.
Having thought about devops and monitoring I must admit that I am not happy about where it was heading. I love LPI's generic and practical approach so I spend some time about that regarding devops and monitoring Yes, a devops guy needs to know about monitoring. Yes, he should know that there are a few popular open source projects that do monitoring: Nagios, Icinga, Zabbix, Prometheus (if you must insist allthough I think it is not nearly mature enough). No, he should not become an expert in one of these packages. (well, I could say it must be Zabbix but 10 to 1 somebody will see that completely differently) But we can tell students about things like: -Be aware of sizing. The amount of monitorin information is the number of items times the number of servers. -Know the difference between storing in a rrd database or a sql database or elastic database and the difference in housekeeping. -The sort-of standard way how return/errorlevels are organised: Nagios/Icinga: Plugin Return Code Service State Host State 0 OK UP 1 WARNING UP or DOWN/UNREACHABLE* 2 CRITICAL DOWN/UNREACHABLE 3 UNKNOWN DOWN/UNREACHABLE Zabbix: Any exit code that is different from 0 is considered as execution failure. Prometheus:? (couldn't find it, pointers welcome) so, there you have it. I hope this is of use to people.
