When a monitor remains in Trouble, Critical, or Down status beyond a specific duration, you can notify configured user alert groups with the
Escalation Settings. You can set multiple escalation times, trigger
IT automation, and choose how alerts are delivered.
Whenever the monitor’s status improves i.e., changes to Up, or worsens i.e., changes to a higher severity, an update alert is sent as per your escalation configuration. After each status change alert is sent, the escalation countdown resets automatically.
To setup contact for receiving mails or voice calls only if there is an escalation, you will have to create a specific user group with the contacts that can be contacted during escalation.
