Netflow Analyzer Data Interpretation
Hello,
I am new to Netflow and am trying to understand it better.
What I have done is selected on Hourly Report, and am getting live feeds from the routers. I get a graph, and corresponding table showing data usage in GB, and also on selecting any particular interface, I get top speeds, hosts, conversations, etc.
This is where my confusion lies. I see that the data shown immediately under the graph is refreshed every minute.
1. Can you please let me know how often is this graph refreshing itself (I presume from my understanding its 1 minute)?
2. The data shown immediately below the graph (in GB), is it the data for the immediate last 1 hour (since I have selected 1 hour report)? If so, then is it also getting refreshed every minute (for instance, 10.21 - 11.21, 10.22-11.22, and so on)?
3. Regarding the top hosts and conversations, at any particular instant when I look at them, is this list based on the last 1 hour, or the last 10 minutes? (I have selected the last 1 hour report).
4. For the speed, is it showing the average speed for the last 1 minute or the 10 minutes or the last 1 hour?
5. Pertaining to the utilization, is it also for the last 1 minute or 10 minutes or the last 1 hour?
Please note I have selected the Hourly Report tab when viewing my dashboard.
I have seen the forum and its queries, but am still unable to understand (being a non-IT guy
). As such, I dont understand the concept of granularity very much.
Can you please provide me an insight into the above? This can be extremeful useful for new guys like me, to understand the data shown, if we can just get the above answers.
Thanks a lot.
Thierry
