Setting Alarm Trigger Conditions by Time Period
Last updated: 2024-01-20 17:28:40
Overview
For business nature reasons, different alarm trigger conditions need to be set for different time periods. For example, an alarm should be triggered when the number of logs containing errors exceeds 100 during work hours (9:00 AM to 6:00 PM) or when this number exceeds 10 during off hours (7:00 PM to 8:00 AM).
Configuration method
Query statement 1:
error | select count(*) as error_count
Count logs containing errors
Query statement 2:
* | select hour(now()) as hour limit 1
Trigger conditions:
($1.error_count>100 && $2.hour>=9 && $2.hour<=18 ) || ($1.error_count>10 && ($2.hour<9 || $2.hour>18))
Use the trigger condition expression to specify a trigger condition and threshold. Here,
$1.error_count>100 && $2.hour>=9 && $2.hour<=18 indicates to trigger an alarm when error_count exceeds 100 between 9:00 AM and 6:00 PM, while $1.error_count>10 && ($2.hour<9 || $2.hour>18) indicates to trigger an alarm when error_count exceeds 10 between 7:00 PM and 8:00 AM.
