Disabling storage of ser.gz and rrd at runtime #310

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
I would like to have the possibility to stop the storage of statistics on the 
disk at runtime, because i've no control on the application context and i 
cannot reload it to make javamelody reload the javamelody.disabled parameter.

SO it would be nice to have a "javamelody.disable-io" parameter that is not 
cached in a static final variable and tells CounterStorage and Jrobin classess 
to suspend writing of new and existing files.

Would it be possible?

Sorry but no, this is not a valid use case.
In a nutshell, if you want to monitor something, it should be anytime or not, 
because otherwise you will not have a significant context.
