Hello,
Per the official AppDynamics documentation, a single node Event Service cluster is not supported for production and should be used for PoV or testing purposes only. By default Event Service will be installed as "production" deployment, and expects such deployment to be on, hence it will fail/crash if it is run on single node.
To run a Single node, you will need to configure the events-service-api-store.yml accordingly:
-
Comment out the following line (by putting "#" in front of the below line):
cluster.initial_master_nodes: ${ad.es.cluster.initial_master_nodes}
|
-
Add the following line under the above:
discovery.type: single-node
|
- Comment out the following line (by putting "#" in front of the below line):
discovery.seed_hosts: ${ad.es.node.unicast.hosts}
|
- Restart Event Service to apply new configs.

If you encounter any issues when running the above configurations, please reach out to the AppDynamics support organization.
