Application Monitor going into 'unknown' state a few times a day

I keep getting email alerts 3 or 4 times a day reporting services going down however these are services that are down already and their status hasn't changed, I am finding that the Application monitor is going into an 'Unknown' state and so when it recovers it then shows the service as 'down' initiating an email alert. This appears to be happening on all the Application monitors I have checked which is concerning.

Has anyone experienced this issue before, I have raised a ticket with Solarwinds but the process seems very slow I assume they are very busy.

I am running SAM 6.4.0 and NPM 12.1 on Windows 2008 Servers.

I currently can't update to a later version due to the OS I am running (don't ask!)

Any help in this matter would be appreciated, thanks.

John.

Whats your alert trigger condition and alert reset condition?

If you set to alert when the app is status Down and to reset when trigger condition is no longer true then that why you keep getting the alert.

As for why the applications that go in unknown status there can be multiple reasons :

-network communication: check with your network admins if they have QOS in place and if the WMI traffic coming from SW server is not drooped as the network gets busy.

-antivirus/IPS/Firewall on target servers

-low resources on target server

-low resources on the Solarwinds server or over polling. ( check Polling completion and polling rate : Orion/Admin/Details/Engines.aspx )

-over utilization of SAM licence

-slow Database that cant keep up with the writing of data.

Hi John.

You could have a go with this KB here: Incorrect status of services displayed in SAM - SolarWinds Worldwide, LLC. Help and Support / A SAM template status shows Initial Poll in Progress - SolarWinds Worldwide, LLC. Help and Support

I'm getting the alerts because the applications are going into an unknown state then returning to their original state which was down.

The alerts have been in place for many years but I have only been getting this issue for a couple of months. This is happening on numerous Servers I am monitoring, obviously its only noticeable on those that have a service that is in a down state.

I have checked resources and these aren't low, polling completions on both of my pollers are between 99.99 and 100% SAM polling rate is only 11%

My SAM license is an 'Unlimited' one

I will of course check with my DBA that the Database is performing normally.

Thanks for the response, I have looked at the links but these seem to refer to problems with Initial Polls which isn't what I am experiencing, thanks again,

You may want to take the component out then add it back in. I had this happen before in a big instance of SolarWinds, it was volume in that system. I also increased the polling time intervals, this helped especially in SAM.

I too am having this exact same issue right now. I have an open case on this. I am running SAM 2020.2 and this issue is happening particularly on 3 Linux servers.

Our application is for monitoring certain services (5 total) that run on all Linux servers. Two of those services are incorrectly reported down on these three servers, and since the application is continually going unknown and then to a down state, we get multiple email alert notifications on these servers throughout the day.
