Chapter 46. Alerts
Table of Contents
PPEM supports sending alerts to users and user groups via email to monitor agents, hosts, and instances. To send alerts, you must configure an SMTP server.
For an alert to be sent, an alert trigger must fire. An alert trigger fires when the value of a metric is below, equal to, or higher than the specified threshold. Metrics are stored in data sources, for example, in the repository database.
To determine the alert trigger threshold, alert trigger rules are used. An alert trigger rule is a set of one or multiple conditions containing logical operators and values. For example, an alert trigger rule condition can include the > logical operator and the 0 value. With such a rule, the alert trigger fires if the value of the specified metric exceeds 0.
Relations between multiple alert trigger rule conditions are determined by the AND and OR logical connectives.
For alerts to work properly, you must first install and configure logging and monitoring tools.
Important
The alerts functionality is in the beta phase. Currently, only pgpro-otel-collector metrics can be used for alert triggers. Other existing limitations are specified in the corresponding instructions.
