Alert Manager Templates in 01Cloud consist of a set of predefined rules that users can conveniently install directly from the alert section. These templates simplify the process of setting up alerts by providing ready-made configurations that can be quickly applied to monitor various aspects of your systems and applications.
Example of a MySQL template:
- alert: MysqlDown
expr: 'mysql_up == 0'
for: 0m
labels:
severity: critical
annotations:
summary: MySQL down (instance {{ $labels.instance }})
description: "MySQL instance is down on {{ $labels.instance }}\n VALUE = {{ $value }}\n LABELS = {{ $labels }}"
- alert: MysqlTooManyConnections(>80%)
expr: 'max_over_time(mysql_global_status_threads_connected[1m]) / mysql_global_variables_max_connections * 100 > 80'
for: 2m
labels:
severity: warning
annotations:
summary: MySQL too many connections (> 80%) (instance {{ $labels.instance }})
description: "More than 80% of MySQL connections are in use on {{ $labels.instance }}\n VALUE = {{ $value }}\n LABELS = {{ $labels }}"
