After decommissoning a server, how can we make the data and graphs availabl= e for a period of time through the Hobbit interface. The idea being that we can compare new server loads, performance and quirks= with the old, if we need to. (Keep in mind, the actual server will be long gone, we just want access to = the rrd graphs and history) I would like to create a subpage with decommissioned servers, have everythi= ng remain green, and have historic data viewable?
If you can live with them not being green, why don't you just disable all tests on the server ? They'll show up blue, but you will still have access to all historical data, graphs etc.
Assuming the correctness of the following concept Server_Utilisation=3Df(CPU utilisation,memory usage) Where f() is not clearly defined yet, can we use hobbit to generate a repor= t of most utilised and least utilised servers?
You'd have to do some data extraction from the rrd files (that's the only place historical performance data is stored), and then apply your magical f() function to those data.
A slightly different approach is to use the "Metrics" report in Hobbit and look at only the memory- and cpu-utilisation for a group of hosts. It won't give you a report, but it may give you a hint of what servers to look at.
