Your assumption is wrong unfortunately. I wish I had made a mistake, but stats.micemn.net's Cacti config is 64bit for gathering of stuff. And using SNMPv2 according to the configuration. Nothing special in logs either showing a problem.

Cacti Graph using SNMPv1?

by Justin Krejci

'micemn-gateway-2.micemn.net - Traffic - Gi0/2' in Cacti is exhibiting signs of using SNMPv1 counters (frequent gaps at higher bandwidth usage) Is this a known issue? If not I presume someone at iphouse can fix this easily. The "Fix64bit" plugin for Cacti is great for correcting this condition on the fly if my assumption on the problem is correct. ######################################################################## To unsubscribe from the MICE-DISCUSS list, click the following link: http://lists.iphouse.net/cgi-bin/wa?SUBED1=MICE-DISCUSS&A=1

Re: Akamai Traffic on MICE

by David Farmer

I was planing to make that part of the discussion with Akamai. However, even without MICE we were going to need more servers for next fall. It seems our servers were shedding demand much of the spring. Since school is out, our demand has dropped by about 50% over the last 2 weeks, and is down about 65% from our Spring peak about 6 weeks ago.

Re: Akamai Traffic on MICE

Is there any way we can use the amount of U/Akamai traffic being pointed at MICE as an incentive for Akamai to come to MICE themselves?

Re: Akamai Traffic on MICE

by David Farmer

As was noted we installed a 2nd GigE between the two switches yesterday. Things are looked good last night we peaked at 1.7Gbps most of that coming from the U's Akamai Stack. Akamai tells me we are maxing out our servers again, it looks like we were maxing them out most of the spring anyway. The Akamai servers are putting out a little less than 2G from about 7am to 11pm. I believe we are seeing more traffic in the evening going to MICE because most of the other Gigapop networks have more of a business day demand curve, so Akamai serves more of the demand out of MICE in the evening as demand from the Gigapop networks slack off. So I think things are much better now, we should get the new switches installed and people moved over but we shouldn't have to rush it. The University will work with Akamai to get more servers over the summer, but I would hope we would have everyone moved over to the juniper switches long before that happens.
