Earlier the Nagios alert monitor was percent based as in when the percent of OSD
down is greater than 80, it will send alert.
>check_prom_alert!ceph_osd_down_pct_high!CRITICAL- CEPH OSDs down is
more than 80 percent!OK- CEPH OSDs down is less than 80 percent
Updated the code in nagios values.yaml to send alert when even 1 OSD is
down:
>check_prom_alert!ceph_osd_down!CRITICAL- One or more CEPH OSDs are down
>for more than 5 minutes!OK- All the CEPH OSDs are up
