Notice alarms did not disappear until the restart

Min Thant Aung [SLC] [DevOps Advocate]685 25th January 2024 0 Comments

Hello all,

I have a customer with failover setups where active and offline agents are in different geo location.
Each agent is setup with its local Cassandra node.
When the network interruption occurs, we saw the below pop up notice alarms in the alarm console as shown below, which is expected. (from online agents)

However, after the customer resolved the network connection issue, by right it should disappear but in this case, the notice alarms are still being there.
I tried to check the logs and I did not see any issue with failing heartbeat and sync issue as well.
When we check the failover status on the DMAs in the cluster, we see that on every offline agents, it was showing the status “No responders are available for the request” => which I believe, pointing to issue with connectivity or availability of the Cassandra node.

When I was checking the failover node tool status, everything is up and running and there is no errors happening on the DMAs as well.
To remove the status, on offline agent, I had to stop the Cassandra service, stop the offline DMA, restart the Cassandra service and restart the DMA again to resolve the issue.
Strangely after that, the notice alarms that were not cleared before are gone as well.

Can someone please help me why the notice alarms were only being cleared after the Cassandra service and DMA restart?
Thank you for the help.

Hi Min,

Our DEV team confirmed that the notices should clear automatically. So, as this is not the case for your customer, I would suggest we take a closer look at their setup via a collaboration ticket.

Hi Min,

I believe notice alarms need to be manually cleared by selecting them and from the right-click menu clear them.
I’m not sure why it’s a manual process though.
But no need to restart the DMA to clear them.

Hello Jeroen,
Thank you for the info.
Indeed, only need to restart of the offline Cassandra nodes to clear the notice alarms.
However, before clearing them manually, just want to know the reason why the notice alarms are still existed.
