Solarwind dashboard nodes on maps show down when indeed they are up

I havent faced this sort of an issue, as far as I understand I dont think the data on dashboard has anything to do with your job engine V2, the data on the dashboard is pulled from the SolarWinds database directly. You should probably do a complete health check of your environment once. To the best of my knowledge when polling is initiated your job engine kicks in and talk to the end devices to get the stats, but it will not overwrite the information in your database that is already there (which is status of the device be it up/down - that should still be intact, the status that was picked up in the previous poll). Hope this helps.

Small correction with my statement: If you are stating your additional poller/main poller on which the device is managed - If that cannot ping (ICMP) the device within then definitely yes the device will be shown as down in SolarWinds even though the device is up and running. Make sure connectivity between SolarWinds and end device is intact and SolarWinds can reach the device within optimal latency.

Thank you Vinay. So the relation here is once the job engine starts, there is no reachability from the main poller to lots of the node. if you stop the service, all node become reachable with very low latency.

Honestly not sure how I would fix this, but let me list down a few things

1. Firstly i would check if main poller is overloaded, if it is then I would free up some and move it to additional poller. Ideally i keep less number of devices on my main poller. This should fix the issue if it has anything to do with load or performance.

2. I think if you raise a case with SolarWinds they would either suggest you to clean up sdf/db files on your poller or reinstall Job Engine service, but before you do that try if point 1 works for you.

Thanks once again. An engineer was assigned when we attempted to do an upgrade. He mentioned it was not overloaded but we have been adding some more nodes just by icmp so will proceed to unmanage them to see.

I think I may want to also try your first option of moving some items to additional poller. how do i achieve this please?

Settings -> Manage Nodes -> Select the node that you want to move over -> Click on Edit properties -> Under Polling you will see Polling Engine click on it and change it to another poller in your environment -> Submit

Note: You can do this for multiple nodes/devices as well by selecting multiple nodes in manage nodes.

But firstly, all additional pollers should be able to talk to the end device, I do not know how your current environment is configured. If only your additional pollers can talk to end devices then this will work.

Plus can you tell me if you have additional pollers in your environment ? Settings -> My Orion Deployment (do you see additional pollers apart from main poller here ?)

I tried this before but unfortunately I do not see our standby poller showing there. we have two application servers in HA mode.

Ok in that case there aren't any additional pollers, please ignore my point. Thanks for the update.

I have mad some headway. I have unmanaged a lot of interfaces we added recently only for ICMP and everything seems fine now. we decided to monitor all ISP interfaces so what this means is that you have monitoring to about four IP's all on the same device.

I now would have to explore how to use the standby server as an additional poller so we can use it for this purpose. Any suggestions?
