No data received in ALE 2.0 feed-reader
Problem:

ALE version : 2.0.0.5

 

Issue : No data received in the ALE feed-reader using RTLS



Diagnostics:

Need to verify whether we receive the data in feed-reader,

[root@websocket-server ~]# /opt/ale/bin/feed-reader -e tcp://localhost:12001
Attempting to 'connect' to endpoint: tcp://localhost:12001
Connected to endpoint: tcp://localhost:12001

From the ale-jwebapp.log we will be seeing the following error,

2016-05-23 12:51:31.304 UTC [metrics-logger-reporter-1-thread-1] INFO  c.a.a.c.metrics.RegistryManager - type=COUNTER, name=com.aruba.ale.persistence.redis.PersistenceManager.DB-Total-IncomingMsgCount, count=0

From the ale-wstunnel.log we will be seeing the following error,

2016-05-23 12:51:31.304 UTC [main] INFO com.aruba.ale.wstunnel.TunnelClient - Connecting

Solution

In this scenario the communication issue happened because of the incorrect RTLS password in the controller.

Troubleshooting done:

1, Login to Aruba controller GUI and click on  Configuration-->Under WIRELESS-->AP Configuration.
2. Select the Aruba AP group and under profiles selected AP.
3. Select the ethernet interface which is in use and then select AP System Profile.

Update the correct RTLS username/RTLS password.
4. Save configuration .

 

Once after making the above changes we can verify that the data starts received in the ALE feed-reader by executing the following command,

[root@websocket-server ~]# /opt/ale/bin/feed-reader -e tcp://localhost:12001
Attempting to 'connect' to endpoint: tcp://localhost:12001
Connected to endpoint: tcp://localhost:12001
