Issue/Introduction

After Logging into DX NetOps Spectrum OneClick, Events and Alarms are not displaying in the console.

Configuration

Resolution

When running the below command:

 

sudo netstat -anop | grep -i 1400*

We see the OneClick Server listening on port 14001 but it's not connected to any SpectroSERVER's on that port. For example:

tcp6 0 0 :::14001 :::* LISTEN 55394/java off (0.00/0/0)

tcp6 0 0 OneClick_HOST:40020 MLS_HOST:14002 ESTABLISHED 55394/java off (0.00/0/0)

Check and ensure that the vbroker.se.iiop_tp.proxyHost parameter in the <SPECROOT>/tomcat/webapps/spectrum/META-INF/context.xml file is the OneClick Servers hostname.

 

If any changes are made to this file, a tomcat restart must be completed for the changes to take effect.
