Instance Overview
An area that displays the status of DB instances included in the monitored group and the current status of alerts for each instance.
Each instance is assigned a color and, in the case of TAC/TSC clusters, is grouped together and deployed.
In Instance Overview, the users can see the status of each instance at a glance. \ If an Alert item appears in the right-hand Alert section, it indicates Normal status. If Agent Disconnected or DB Down occurs, the corresponding status is displayed on the right.
The users can hide or expand the Instance Overview menu by clicking the arrow button on the right.
Instance Status Description
The status of the monitored DB includes Normal, Agent Disconnected, and Down.
Normal: The DB is running, connected to the TPM Agent, and collecting metrics.
Agent Disconnected: The DB is running but is not connected to the Agent, so metrics are not being collected.
Down: Indicates that the DB instance is down or unable to establish a connection.
Caution
If TPM Agent data collection and transmission are paused due to firewall settings changes or other reasons, no indicators may be visible in the Normal state. Therefore, if real-time indicators are not visible in the Normal state, it is necessary to check the monitoring DB machine and TPM Agent logs.
Import Instance
Super Admins can register monitoring targets by clicking the 'Import button'.
Alert Events
The users can view the status of alerts generated for each instance on the right side of the instance item. Clicking the corresponding button allows the users to check the status of Error/Warning alerts.
Instance Selection Feature
The users can select a specific instance from the Instance Overview to display only data for that instance in the Card View and Custom Area.
When an instance is selected, Auto Refresh stops in all areas of the Dashboard, and all data in all areas is frozen to the point in time when the instance was selected.
