Gray NWA Dashboard in JAVA Systems



When we login to Netweaver Administration (NWA) on any JAVA system, we get greeted with the Dashboard. This dashboard gives us overview of how system is behaving and overall health status. But sometimes the metrics shown in this dashboard are grayed out or visible as Gray traffic lights only. Thus no information is populated and key system indicators are missing. In this post, let’s check out how to address Gray NWA dashboard in JAVA Systems.

Cause of the issue

Monitor data of “System Overview” is retrieved by invoking methods of SAPCCMS WebService.
The reason for the problem is because the call to SAPCCMS.cgi is failing with 401 unauthorized error because the methods e.g. PerfRead, MtGetTidByName and/or other methods are protected with service/protectedwebmethods = SDEFAULT.


How to Address this Issue

In default trace, you can see the logs as mentioned in “Additional Checks and Useful Logs” section. In same logs, you can identify the method which is in issue, this is highlighted in RED in section “Additional Checks and Useful Logs” of this post. To correct the Gray dashboard issue, we need to exclude these methods. This is achived by updating the parameter “service/protectedwebmethods” in DEFAULT profile with those method names.

service/protectedwebmethods = SDEFAULT -PerfRead -MtGetTidByName ...-<Method>

Restart of SAPSTARTSRV service is required to get changes implemented. You can do same via below command.

sapcontrol -user <SIDADM user> <password for SIDADM> -nr <instance number> -function RestartService

In some cases, you may need to restart whole JAVA system along with SAPSTARTSRV service, i.e. full clean restart of SAP JAVA system. Once system is restarted, you should see dashboard populated with required data and Gray dashboard issue should be resolved.
