Exception on DB Agent

[CommunityUser]

Dear,

Getting an error whiie displaying info about DB on the Database Live View...

"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 occurred while getting wait state information."

I'm using a MariaDB 10.0.26 as a cluster of 3 actives nodes on CentOS Linux release 7.2.1511

Agent Log is attached

Best regards

Alexandre

Hello
Is your controller on SaaS or OnPrem?
If the latter, you need to start the event-service:

https://docs.appdynamics.com/display/PRO42/Start+or+Stop+the+Controller#StartorStoptheController-Sta...

Otherwise, as stated, contact the support

Hope it helps and fix the problem

Dear,

On Premise, Yes.

I've restarted the event-service and it worked, thanks a lot.

One more question... Do you know how app dynamics handle DB Cluster (MariaDB) ? I mean that I want to get database statistics on all nodes ? (you can only add one database with the same name...)

Francophone? 😉

Normally, you monitor the physical nodes not the logical one. If you want
an aggregate perspective, you can look at the Database from an application
perspective, Have you deployed Java or .Net agents?

Are you already in touch with an AppDynamics sales or presales person?

A bientôt

Oui, Francais... mais basé au Maroc.

I'm using Java and deployed the agent on Tomcat 8.

It seems ok, but I've got a problem with the database link... as I'm using 3 databases in the cluster.

Not yet..., but I would appreciate some help and as well for the problem with the system agent (my previous post).
