Timeouts happen when operations against the database take longer than the server side timeout. High alert on larger amounts determine potentially as a percentage of read throughput.Īstra_db_read_requests_timeouts:rate1m and astra_db_read_requests_timeouts:rate5m - A calculated rate of change (over 1 minute and 5 minutes, respectively) for read timeouts. Using these rates, alert if the value is > 0. Cassandra drivers retry failed operations, but significant failures can be problematic. Using these rates, alert if the value is > 0.Īstra_db_read_requests_failures:rate1m and astra_db_read_requests_failures:rate5m - A calculated rate of change (over 1 minute and 5 minutes, respectively) for the number of failed reads. You can request that rate limits are increased for your Astra DB databases.
