Getting Started: Alerting
Open the Alerts > Rules page and click Create to configure an alert rule for the
temperature metric using the Rule Engine.
The following condition evaluates to
true and creates an alert if the average value for the last three samples exceeds
avg() > 50

0. Otherwise the rule engine ignores measurements timestamped earlier than
1 minute from current time.
Return to Data Entry and submit a few commands with values greater than
series e:br-1905 m:temperature=55
Open the Alerts > Open Alerts page in the main menu to view currently opened alerts.
Now, insert some commands with lower values to ensure that the average of the last three commands is less than
series e:br-1905 m:temperature=20
Refresh the Open Alerts page to verify that the alert for
temperature-too-high is closed.
