The UFW rule looks OK, as far as I can tell.

PROTO=2 is IGMP, which has nothing to do with the TCP connection required for 
Prometheus.

 

Sounds like you have a typo in your UFW rules.

Hi All,

 

I just put Prometheus on a virtual machine following this guide 
<https://computingforgeeks.com/install-prometheus-server-on-debian-ubuntu-linux/?unapproved=12580&moderation-hash=57a1d9c25283ec04248de5242c203235#comment-12580>
 . The service is running; I don't see any errors in my Syslog that I can pin 
directly to Prometheus. I was hoping I could get advice on where to look; what 
might be wrong? I am leaning toward the config file, but as far as I can tell, 
it should be OK for just this basic setup.

 

My issue is I don't get a webpage when I try to access the server. UFW is 
allowing that port. Prometheus service is running. 

 

The only thing I see that is odd in the Syslog is:
