We've come to the end of our tour of the Grafana alerting system. Using Logstash, we imported real-time hardware data via the powermetrics command. We took a closer look at thresholds and time regions in order to get familiar with Grafana alerts. We learned about the Grafana alerting state machine and set up threshold alerts for excessive fan speed and CPU temperature. We also configured an email notification channel for sending an alert message and triggered an alert. Finally, we explored some troubleshooting options for when things don't work the way we expect.
While it may not contain all the bells and whistles of its competitors, Grafana offers a solid system for generating notifications from data-driven alerts. Although it is configured from the Graph panel, the alerting rules are monitored by the Grafana server's backend. It can monitor multiple queries and logically combine a number of threshold conditions, and gracefully handles edge cases...
