Ratings for servers
Most are Unavailable,
172.30.102.100 is normal for 5 minutes then goes to unavailable
What does that mean, was it reachable for only those 5 minutes?
172.31.102.156 goes from unavailable top no data. What is happening here?
Also since there are so many unavailable does that mean that these servers are just not being seen by the monitors (these are GIgaStor feeds)
What conclusion can I draw from this, that the probes (be it spans or taps) collecting the data are not consistent or are servers bouncing?
Thanks for your response Stuart
You helped me form a premise.
I do believe this "unavailable state" of the server is by design.
Upon closer inspection all the server IPs are from server VLANs, so it would make sense to block/discard connections to the servers from non-server subnets (ADA monitors are not in server VLAN!).
Hence a bunch of red, that gets acknowledged.
But periodically communication between servers will happen and I'll get measurements.
This may the the effect of an ACL for security.
