While accessing (Database monitoring) collector data (or other tabs, such as Queries or Sessions) you may encounter one of the following errors:
Case 1
Error
We aren't able to load data from the event service. If this is a SaaS controller, please open a support ticket. If this is on-premise installation, please make sure that the event service is running. See the documentation for instructions on starting the event service. For more details on this error, please see the controller server log.
Error
Error occurred while getting wait state information
Case 2
Error
The server encountered an internal error () that prevented it from fulfilling this request
Error
Error occurred while getting wait state information
Case 1 |
Root cause: "request timeout"
|
Case 2 |
Root cause:
|
NOTE | It may also be that the Events Service in use is configured on another dedicated host machine. Just make sure the Events Service is running and that it can be connected from the Controller. The easy test would be $> curl http://<events-service-host>:port/healthcheck?pretty=true
$> cd Controller/bin
$> ./controller.sh start-events-service
This issue usually arises because either of these Controller properties (through which database monitoring is configured) have the following issues:
appdynamics.analytics.local.store.controller.key
appdynamics.analytics.local.store.url
