All network devices : Port Status Warning

Hi, Since the keep announcing in Nagios Core, I decided to try Nagios XI (Nagios XI 2024R1.3.2)
My main objective is network monitoring, and there I ran directly into problems. On all network devices, wile bandwidth is nicely monitored and graphed, the port status for each port on each device is in Warning. So the services for any network device looks like this:
Code: Select all
Ping Ok
Port 1 Bandwidth Ok
Port 1 Status Warning WARNING: SNMP error: No response from remote host "x.x.x.x"
Port 2 Bandwidth Ok
Port 2 Status Warning WARNING: SNMP error: No response from remote host "x.x.x.x"
Port 3 Bandwidth Ok
Port 3 Status Warning WARNING: SNMP error: No response from remote host "x.x.x.x"
(where x.x.x.x is the actual ip
)
Simple as it seems I still deleted all devices and added two (A mikrotik router and a HP switch) following the instruction video, no difference.
What did I miss ?

tonnag,
If I was to take a guess, you likely have one of the following issues:
- The SNMP service isn't running on the hosts
- The SNMP traffic is blocked (perhaps SNMP is disabled)
- Your SNMP credentials (e.g. community string) are incorrect
Have you considered all of the above?

Hi Cory,
Yes, I considered them, but dismissed them quickly.
The configuration wizzard (where I entered the community string) discovered all the interfaces, and the bandwidth is being graphed perfectly for the interfaces. It's just the status that's giving the "WARNING: SNMP error: No response from remote host"

Hi @tonnag,
Can you try running the incorrect commands from the CLI and let us know what it returns?
You can find the command the particular service is running in the CCM.
Thank you!

Hi @gwesterman
That was a pretty good idea!
The "Run Check Command" failed in the GUI and also at the command prompt.
It took a minute but I found out why .....My snmp community string ends with an exclamation mark (!) which is missing in the command.
Next I have removed it from one device, which then went all green in XI.
So I found a bug in XI then, for this is working in my nagios core. I have not yet tested if the exclamation mark is the problem or the fact it's at the end of the community string.
Thanks!

tonnag,
Glad to hear you got this worked out. I'll create an issue internally to look a bit deeper into a potential bug. Marking this thread as resolved and locking it.
