What, exactly, is detected as a failed database connection?


Can somebody clarify what, exactly, the “failed database connects” metric referenced in the “Detect failed database connects” problem detection rule represents? In a problem card that was opened via this rule, the “Metric anomaly detected” lists “Service connection failures fraction”. I am not clear, what this metric represents… what exactly is the problem detection based on? I presume its a failure in the call to whatever framework is being used in the monitored code to establish a connection to a DB... but I want to make sure that this is a correct understanding... the reference to a "service connection failures fraction" makes me question whether I have the correct understanding.

You are right. Each time when framework responsible for connection acquisition is not able to establish connection before transaction, you have this metric violation.
