You can configure alert rules, alert metrics , and threshold values for Retrieval Engine Edition instances in an easy and quick manner. The system can send alert notifications by phone calls or text messages.
Default alert rules provided by Retrieval Engine Edition
Retrieval Engine Edition provides default alert rules, including multiple common alert rules. This way, you can create alert rules in an easy and quick manner.
The alert rules are created for all clusters. The alert rules include the general query duration in Havenask, the memory usage of QRS workers, the CPU utilization of QRS workers, the memory usage of Searcher workers, the CPU utilization of Searcher workers, and the disk usage of Searcher workers. You only need to add alert contacts and alert notification methods and enable the default alert rules.
