Did you know that K2 comes with performance counters?
Perfmon can give you a monitoring session for K2 based on the performance counters.
K2Server adds a number of counters that covers processes, worklists, connections and so on which gives you insights into what is happening on your K2 Server.
Cobus just confirmed that by updating the config file
<K2 blackpearl dir>\Host Server\Bin\K2Server.setup you can disable the performance monitoring. thanks C.
There is a KB on K2 performance monitoring available for download http://kb.k2workflow.com/ArticleAttach/Monitoring%20the%20K2%20blackpearl%20Environment.pdf
