Hi Jakob,
I am looking to do a pilot along these lines now. We use Netscout probes at many points within our network. I want to produce Top Conversation reports for any interval with high utilization. Here is what I know so far. - A script to be written will be executed upon an mrtg threshold. In fact we already have a script to log each interval and also display current performance issues to a web status page (utilization, errors, congestion, etc.). This script will be extended or spawn another to handle top talkers. - The only problem with this technique is that what will be reported is the top talkers for a 30 second interval AFTER the 5 minute mrtg threshold was hit. So it is a bit out of sync but I believe it will still allow us to capture the power users consuming bandwidth on our wan. - I need a technique to relate target name to a Netscout agent name. This will hopefully be dynamic and stored into the config of the probe and extracted periodically by another script....but I'm not sure yet. - The script will execute a Netscout cli command (dvsnap) to request from the agent the TopN Conversations (source and destination) and store the data probably in a csv file with the name relating to the mrtg target name and a time stamp (ex. targetName.20001122.09.25). - An interface (or button) will be added to our main status web page to review TopTalkers for a given target....somehow. I do not have a vision of producing a graph. The data will be csv and would be converted to html table format upon viewing. We have everything under the sun in this format (can you say datawarehouse without the house?) and this will work perfectly well, this I already know. Note that the collection of ALL conversations as a report is not the goal, only those during peak utilization and also only TopN. Additionally only wan links will be targeted (where the money is spent) but I hope to add one-off targets for adhoc usage for performance analysis for lans when needed. I believe this strategy will scale and we will prevail with this data before the end of the year if Netscout lives up to my expectations. The only aspect I actually have done so far is a quick test with Netscout's cli dvsnap command which seems to fit the need. So I have quite a bit of work ahead of me but it will be well worth it provided I'm successful. cheers, brad... -- Unsubscribe mailto:[EMAIL PROTECTED] Help mailto:[EMAIL PROTECTED] Archive http://www.ee.ethz.ch/~slist/rrd-users WebAdmin http://www.ee.ethz.ch/~slist/lsg2.cgi
