Hi I have been "playing" with mrtg (how do you say that in normal english?) http://people.ee.ethz.ch/~oetiker/webtools/mrtg/
MRTG was designed to provide a LIVE visual representation of this traffic but it can also be used to display other information. I have create a small servlet that aquires some basic stats from mmbase (memory and cache hits/total) currenty I am only getting information that is easely avaiable but the result looks very good (so I say..) creating new "graphs" is quite easy and at the server side you don't have to keep to much data (only simple counters) The node caches information is displayed in hits/s :) here is a sample result http://carlit.mine.nu/~keesj/mrtg-example/ is shows the results of a small stress test I first created 10000 people node then I played around with the cache settings and looked at the behaviour when multiple rmmci clients wheren accing the nodes (max speed reached is 298 cache hits/s on a 5 minute average, but the clients wheren only getting +- 60 nodes a second any idea why?) the code does a peole.getList(null,null,null) and then iterates over the recieved nodes) I would like to add more "stats" -bridge stats -database stats (queries/waiting times/active connections) those are all very small changes. do people feel this is a good way to go? what do you think of the stats? can you help create good stats for mmbase? PS the source code is located in cvs speeltuin/keesj/mrtg and you nee d to create a servlet mapping from the MRTGServlet to /stats.db a sample mmbase-mrtg.conf is also there nice week-end :) -- cat mozilla_rules killall -9 mozilla-bin ;killall -9 mozilla-bin ;mozilla &
