Hi, i have a number of CISCO MDS 9124 switches monitored in NPM.
When looking at the performance data for ports, we rarely see port utilisation go over 20% and never go over 40%.
However, when we watch the ports live feed in the Cisco Device Manager software, we see huge extended periods of utilisation going up to 90% +.
We have performance data set to gather every 1 minute, so statistically we should be seeing at least one spike on the graph yet we never do.
Does anyone else ever see this and/or have a solution?
Regards
