Monitoring supports two types of dashboards, enabling you to check various monitoring information for DB performance. Monitoring is a service included in NAVER Cloud Platform's Cloud DB for Cache, so it can be used without additional charges. The types of dashboards provided by Monitoring are as follows:
- DB dashboard: monitoring information related to DB Server in operation
- OS Dashboard: monitoring information related to the operating system of the DB Server in operation
Through these two types of dashboards, you can check the performance information of DB within the last year based on average values. Each dashboard is configured with various graphic charts. You can utilize these charts in your business by printing specific graphic charts or downloading them to your local PC as files using various extensions.
You can set the user to be notified when monitoring results show that a certain metric has exceeded its threshold or met specific conditions by having them recognized as events. For more information on the detailed usage for event and notification settings, see Event.
Because intuitive search and management for the DB performance information is available without additional charges, we recommend utilizing the monitoring metrics provided through the dashboard for stable server operations, particularly in environments without professional database managers.
