Alerts

An alert watches a counter for you. When its rule is met, it tells the people and addresses on its notify list.

#What an alert can watch for

• A line crossed - "tell me when any table passes 80% used".
• Silence - "tell me when nothing has arrived for a day". Useful for spotting a job that's stopped, or a tap link nobody's using.
• Whatever the rule says - "tell me when more than 5 incidents are open".

#Set one up

1. Open the counter and start a new alert.
2. Say when. Describe it in a sentence, starting "Tell me when...".
3. Check it against real rows. Before it's saved, the rule is tried on the counter's actual data - so you see whether it would fire now, and why.
4. Add the notify list. The people and addresses to tell.
5. Save.
