[Nfd-dev] nNameTreeEntries revisited

[Dehart, John]

All:

I have finally gotten back to trying to complete some monitoring tasks on the NDN Testbed.
In doing so I noticed an interesting occurence yesterday.

I am building up a set of Cacti graphs of monitored data from the NDN Testbed.
A while back we had noticed that the nNameTreeEntries counter sometimes grew
without ever shrinking back down. I am still seeing this.

Here are the graphs from Arizona, Memphis and UCLA from the last 24 hours:

[cid:5E93F324-1302-4E62-986C-FE2B40C750BD at seas.wustl.edu]

As you can see the NameTree entries grows on Arizona and Memphis but does not come back down.
I believe we expect it to be more like what we see on UCLA where we get bumps that then come back down.

Also, we have other nodes like the WU node where we have this:

[cid:1B31EE27-7A52-4B90-8046-8CBB999DB4F8 at seas.wustl.edu]

Here we see steady grown over a week long period.

If you are interested in looking at these and other graphs you can find them here:

Any thoughts or suggestions?
