The Advanced Monitoring(OpenMetrics) service is an extension monitoring tool that allows users to monitor various platforms and applications running on their instances. Other than basic system metrics, there are also other ways to collect different metrics for users' varied situation.
By installing and running the Exporter of the target system to be monitored by the server instance created in Compute > Instance, the metrics information of the system can be collected. Once the Exporter is ready, through the System Monitoring service, the monitoring function can be enabled and the collected metrics can be viewed. Just like system metrics, you can generate a chart and use a layout you want as well as generating and managing multiple layouts as intended. Also, similar to the default monitoring of the server, by specifying observation target metrics and thresholds, you can detect abnormal signs of the service. In the case of a situation where the set monitoring condition has been met, you can deliver a message to users via email or SMS.
Metrics are collected every minute and retained for up to 5 years. Aggregate metrics data is calculated in unit of 5 minutes, 30 minutes, 2 hours, or 1 day. The guaranteed retention period per aggregate unit is as follows:
|Aggregate Unit||Retention Period|
|1 min||1 yr|
The max retention period is subject to change depending on the situation, and if it is changed, members will be notified separately.
