Geoevent Processor 10.4 Will Not Start

Question

I just installed a fresh instance of ArcGIS Server 10.4 and joined it to the cluster. After this, I installed Geoevent Processor 10.4 on the same instance and when I do to log in, I get a "No service was found" message on the manager login and REST pages. I checked the license and it's fine. I also checked the logs and here is what the errors are:

| ERROR | rint Extender: 1 | ConnectionState                  | 198 - curator-client - 2.8.0 | Connection timed out for connection string (GISVM01.MYCOMPANY.COM:2181) and timeout (10000) / elapsed (119714) org.apache.curator.CuratorConnectionLossException: KeeperErrorCode = ConnectionLoss

org.apache.zookeeper.KeeperException$ConnectionLossException: KeeperErrorCode = ConnectionLoss for /geoevent/config/keys/ageskey.jks

Any ideas? 10.3.1 worked fine until I tried to upgrade.

Thanks,

Igor

Irfan Tak‌ thanks for that above note about removing and readding the WebSocketContextURL, I had the same problem and this helped me!

Due to these same issues I had to opt from using a stream service with GeoEvents to having GeoEvents receive and add features to a feature service. Then, I used the ArcToolBox "Create SQL Query Layer" to do my select for max(DATE) by unique ID and publish that to a separate service. This workflow allowed me to keep my AGS machine from being resource depleted and also get the "live points" in a map service to be consumed online. This was not the ideal workflow I was hoping for but it allowed me to accomplish what was needed without standing up a seperate machine just for running GeoEvents that could handle a stream service.

Alex,

Thanks for the info. I am kind of relieved that clustering is not being recommended at this time--it's a bit complicated and not living up to the hopes--per that link you provided.

However, I still don't know why would restarting any of the machines in the cluster cause the '400 Bad Request' error. I kind of have an idea as to why--here is some info:

I have successfully created a three ArcGIS Server (10.3.1) cluster; all these run GEP (10.3.1 with a patch installed). The public facing machine is a separate machine running IIS with Application Routing (ARR) doing the role of not only the standard reverse proxy but also a reverse proxy for WebSocket--I don't think one has to have nGinx running in case of Windows. The ArcGIS has the WebSocketContextURL pointing to the Reverse Proxy.

All that works as expected, I think! But, upon any of these ArcGIS Server reboots, I see these these '400 Bad Request' in the GEP log files. The Clustering diagnostic utility for RabbitMQ doesn't find any problem even after reboots. @Here is the error:

com.esri.ges.datastore.agsconnection.AbstractStreamServiceClient During initialization, an unexpected error has occurred. Cannot communication with the Stream Service 'issmon1f'. Error: 'Bad response status 400 Bad Request'. Sep 8, 2016, 10:27:56 PM ERROR

Anyway, I am about giving up on GEP clustering but had spent so much time on that..I am curious to know as to what is happening? I feel like I was almost there: Failover, High Throughput in an ArcGIS Cluster running GEP.

Thanks.
