Why don’t the number of metrics match those displayed at the bottom of graphs in the host details?
Note that check monitoring is counted as one metric. Please check the number of registered check monitors.
It is possible that duplicates of the same metric were posted to the target host within 1 minute of each other and are being counted separately. Please check if the following has occurred.
If the mackerel-agent process has been launched more than once.
If when creating a new server by copying an OS image installed with mackerel-agent, the id file was not deleted and metrics were posted as the same host.
