HCL Connections CP – Enabling Elasticsearch Metrics

Recently, when enabling Elasticsearch metrics, part of the HCL Connections Component Pack 7.0.0.2, I ran into an issue with the “config_blue_metrics.py” script. Which was failing every time I tried to run it (sadly, I’ve “lost” the output and the direct error message which was shown directly after running the python script). The details on how to run this script are described in the official documentation.

Nevertheless, after looking into the WebSphere Metrics Application logs, “AppsCluster” if your HCL Connections Blue Stack environment is installed as a “Medium deployment”, I’ve noticed the following error:

Thanks to my colleague, Herwig W. Schauer, we have found a quite simple solution for this issue. We have changed the default “Context Root For Web Modules” for “Metrics” and “MetricsUI” application. To do this, just open the WAS ISC and navigate to the following entry “Enterprise Applications –> MetricsUI –> Context Root For Web Modules”. We have changed the mentioned configuration in the following way.

We have set the “Metrics” application context root from “/metrics” and “/metrics/service to “/metricsOLD” and “/metricsOLD/service” respectively:

After making the changes mentioned above, we proceeded to make similar changes for the “MetricsUI” application, here we changed the Context Root from “/metricssc/service/rest” and “/metricssc” to “/metrics/service/rest” and “/metrics”:

After the needed configuration is in place, make sure that the WAS nodes are synchronized and restart the “Metrics” and “MetricsUI” applications. By doing so, the issue should be resolved and the “config_blue_metrics.py” script should be able to run without any errors.

Note: You still may get a warning message after running the script: “Warning elasticsearch not found in Kubnetes.”, but this is fine and does not lead to any further problems.
