Why does SolarWinds showing node status Critical but there's no alert or events.

Jason_TF

I'm very curious on the behaviour of my solarwinds setup on some linux & also windows servers.

The node status is showing as critical with no other error messages.

How do I troubleshoot and remove the pesky red critical alert when the server is just working fine.

Check your polling settings for the servers. Also check your agents and see if they are sending data to your polling server. Validate your firewalls to make sure no blocking is happening and you have the appropriate port/ protocol listed in your acl list.

Hello @Jason_TF - When the Node is in a Critical state it is usually due to either a threshold setting or a child object being in a poor state such as an interface or volume. It does not mean there will be an Alert or Event unless you created one to trigger based on those thresholds.

If you hover over the Node name what does the popup state? It might look something like this:

Hello,

I've already hover over the node but it didn't show anything. Other than this node is critical error, I'm not seeing any other messages. CPU, memory & disk utilization for this server is not high at all as this is a low load server, thus I find this very annoying as giving false alarm.

What all are u monitoring from this box? Did u check all its child entity's?

Are u using global threshold?
Are u using enhabced or classic status?

I'm showing a similar issue on my site... Linux server only at this point, but it is showing as 'Node is Critical' without any other messages. I've removed all resources to monitor except CPU & Memory and still showing 'Critical'. Browsing through all of the resources and tabs, I'm not seeing anything in an 'error' state or any sort of degraded/negative state.

Has anyone been able to find anything more, or @Jason_TF, were you able to resolve?

Digging some more into this, but found this article, https://documentation.solarwinds.com/en/Success_Center/orionplatform/Content/core-calculate-node-status.htm. I changed my polling from 'mixed' to 'best' and it started showing green... I did have a few interfaces on the device that I purposefully was not polling, but I'm wondering if it was still seeing them anyway and saw their state. Again, still looking, but good-ish start?

Hi Alan,

I didn't do much, since most troubleshooting didn't yield any result. Thus I unmanage the node & remanage it back, surprising the issue disappear & my node returns normal.
