"Cannot connect to System Management Service" in Health and Wellness tab

[VinodhKumar1]

I am getting an error message "Cannot connect to System Management Service" while accessing SA->Administration->Health and Wellness.

However, I checked the status of all the services like tokumx, rabbitmq, rsa-sms, jetty.

No issues found in any of the services. All the services are running.

/var/lib/rabbitmq partition is also less than 75%.

Help me out to fix this issue.

There is a known issue with the SMS service that should be fixed in 10.6.3. The solution to this issues until fixed is to do the following process.

stop jettysrv

service rsa-sms stop

service rsa-sms start

start jettysrv

If issue is system is allowed to continue in the failed state for a longer period of time, it may cause a complete failure of the UI, which would require the following process.

stop jettysrv

service rsa-sms stop

service collectd stop

service rabbitmq-server stop

service rabbitmq-server start

service collectd start

service rsa-sms start

start jettysrv

Depending on how many and what type of endpoints you have will determine how long everything will run before the initial symptom of "Cannot connect to Systems Management Server" error occurs. If it is occurring at a regular interval, suggest setting up a cron job to run through the first process on a schedule that will keep things cleared up. 

The issue stems from the way the SMS process is handling internal communications, which currently all go over the rabbitmq bus, causing the service to eventually fail.

In newer versions the short step:

[root@NWHOST ~]# systemctl stop jetty.service
[root@NWHOST ~]# systemctl stop rsa-sms.service
[root@NWHOST ~]# systemctl start rsa-sms.service
[root@NWHOST ~]# systemctl start jetty.service

Where short is relative in terms of the time involved.
