On our linux servers we have this basic check:
check system localhost
every "* 08-18 * * 1-5"
if loadavg (1min) > 4 then alert
if loadavg (5min) > 2 then alert
if memory usage > 75% then alert
if swap usage > 25% then alert
if cpu usage (user) > 70% then alert
if cpu usage (system) > 30% then alert
if cpu usage (wait) > 20% then alert
On 3 servers we have postgresql. Is it possible to configure monit so:
- when the basic test alerts, execute a specific program ?
Example:
check process system_busy
depends on system
exec "/usr/bin/psql -U postgres -c \"SELECT * FROM pg_stat_activity;\" > /var/log/postgres_busy.log"
We want another check, to not modify the localhost one.
