Hello, Pierre. In last postgresql.eu conference https://prometheus.io/ was mentioned in several talks. https://www.postgresql.eu/events/pgconfeu2018/schedule/session/2190-using-prometheus-and-grafana-for-postgresql-monitoring-in-tomtom/ for example. That said I had a lot of time invested in munin (and to teach it to use auto-discovery of everything), so personally did not yet switch to use prometheus. I'm most interested in advanced alert criteria that one could setup in prometheus, and if you are looking for best alerting - it is worth investigating. Nagios may still be more popular choice, because it is older, and more widespread. Yet when I was picking monitoring - I needed easy setup and ability to write own plugins with little effort, so I picked munin over nagios several years ago. Also there is opinion worth getting your attention, if you do research on nagios - saying that nagios may be too old for competition - https://www.slideshare.net/superdupersheep/stop-using-nagios-so-it-can-die-peacefully Best, Ervin On Fri, 11 Jan 2019 at 20:35, Ibrahim Edib Kokdemir <kokdemir@xxxxxxxxx> wrote: > > What exactly is your expectation from a monitoring system? If it is just a postgres server that you want to monitor and and regular alerts, nagios is the shortest path. But if you want more, for example enterprise level monitoring system (graphs, history, maps, predictions) and if you have many other servers along with postgres server(s), I personally suggest you zabbix, but zabbix needs some additional helpers like mamonsu or libzbxpgsql for for postgres monitoring. > > Regards, > Ibrahim. > > On Fri, 11 Jan 2019, 18:56 Pierre Ochsenbein <pierreochsenbein@xxxxxxxxx wrote: >> >> Hey guys, >> >> What is for you the best Monitoring/altering for PostgreSQL?
