Hi Jerome, Thanks for this! I tried to analyze quickly but I couldn't draw any conclusion. Some data look dubious. For example the HTTP response time: they say that no HTTP request took longer than 40-50ms. I don't believe this or I don"t understand what it means. Loading a page takes more than 1 seconds overall, spread over several HTTP request but the main request itself takes more than 1 second. Also since myxwiki.org restarts automatically when it cannot access it through an HTTP request for more than 30 seconds, we should see HTTP request taking 30 seconds! Any idea?

Here are a first set of graphs, exported statically from cacti :
http://myxwiki.org/xwiki/bin/view/Admin/Graphs
It includes, hourly, daily, weekly, monthly and yearly averages for :
HTTP response time MySQL connections MySQL queries TCP Response time Tomcat heap (free and used) Tomcat connection rate (requests and errors) Threads (existing and busy) Tomcat throughput (inbound and outbound)
This one is static, but we'll try to have dynamic graphs directly in wiki pages in a near future. We'll keep you posted.

Hi Vincent,
Yes, we can publish some Cacti graphs, for the overall CPU and memory usage of the machine and HTTP response time.
We don't have tools that detect usages per wiki AFAIK.
Note that we plan to add a new machine for myxwiki soon, and configure a load balancer in front of the 2 machines.
Jerome.

Hi devs,
We're accepting new wikis on myxwiki.org as requests come in but we already have 110 wikis created on it.
When do we know we shouldn't accept new wiki creation on that JVM because it's degrading performances too much? Do we have tool to monitor wiki activity and publish on a page which wikis are using the most resources? Do we have tools to display response time stats and see how they evolve over time?
Thanks -Vincent
