Availability Statistics - explanation needed

israelsilva1 over 10 years ago

For a specific switch, I have the following chart showing me the availability status of the node:

Today's node availability is 94.686 %

Now, a couple of questions:

1. If my "Default Node Poll Interval" is set to 120 seconds. Why the chart only shows one pool every 10 minutes?

If I change to every 5 mins chart, it gives me double missed pools, because it's pooling only every 10mins:

2. So, if it was down for 2 pools on the 1st figure twice and down for 3 pools once.

Does that mean that node was down for at least 20mins and 30min respectively?

My "Node Warning Level" is set to 5 mins

Thanks for your help.

Perhaps that poller is getting overloaded? Have you checked your polling completion percentage? Diagnosing Chart and Graph Data Gaps
