Nagios Support Forum

Hi Team,

We had observed a problem for a particular switch interface where the utilization was 0 and graph was not populating on time period 9:00 AM to 12:00 PM UK time. We checked with DR server and observed the same issue.

However the graph started plotting after 12:00 PM UK. The customer needs to know why did the graph didn't populate during particular time period.

Also we checked with the network team and got to know that there was traffic and also there was high utilization during that time.
Wondering what could be the reason?


Please help in finding root cause for this problem and assist in solving this issue.


Thanks in Advance.
