Hi Guys, Is there anyway to sum the transmit and receive utilization. For example create an alert to trigger when the sum of the transmit and receive utilization exceeds 90%

is it possible to forward only critical traps? How is the filter created using the trap viewer?

yes i do mean the transfer rate. We are currently testing the trial version of NTA and we are monitoring a network. The problem we are having is that in order to get the bandwidth usage for the application at different interval throughout the day, we have to manually select the netflow interfaces one by one and then view…

thanks a million andy

how about a Netflow report that shows the top ten applications and their transfer rate for a day?

thanks i just check the thread

this filter will only show the total bytes transfer on the interface the specified time period

We normally use 75% as the benchmark for high utilization. I normally use the Min/MAX/Avg RX+TX chart to look at my utilization pattern. Netflow digs deeper by telling you who is using the bandwidth and how much so that you can for instance do some capacity planning or redefine your network access rules.

Hi Tony, I did use a MIB walker and tested a few OID's. I tried NTA before but it only works with routers that are configured to send the flows to NTA. It would be nice get a poller that shows the different queues and the drops packets for Cisco switches that support autoQoS

i had to configure the source on all the routers with the ip flow-export source command. will the router export flows with the source address if the source interface goes down? The router is able to reach the NTA as there are two links to NTA. Dynamic routing is configured.

Please add the attached Cisco GDOI Mib[View:/cfs-file.ashx/__key/CommunityServer.Components.UserFiles/00.00.11.04.87/CISCO_2D00_GDOI_2D00_MIB.zip]

Corona Technical Services is a great company. I have worked with them in the pass they are very knowledgeable in what they do

Corona is a very good company. Spoke with them on the phone and they seem to be very knowledgeable. They are also very helpful and respond to queries quickly

is it possible to shutdown a server based on a temparature alert by executing a script?

Any has this issue?

It appears that the chart data is accurate when you enter a absolute time period instead of selecting a named time period.

If you do not want alerts from the vlan interfaces then add another filter to exclude vlan interfaces. In out network we have a created a custom property for the interfaces that we want to monitor for high utilization. Namely our wan interfaces.
