 Description  « Hide

At this time, all the monitor mesures are only kept "live" (unlike threaddumps
and memory dumps), closing the visualvm will result the data to be lost (same
thing when the targeted VM crash).

Adding a "save to file" feature to contiously save the data as-is to a file (say
a simple CSV structured file where each column are one of the mesure), will
enable us to keep those stats.

People will be free to do whatever they want with those data.

This could for instance help us to solve the issue 185 applying simply applying
macros on those data.

The Monitor and Threads tab are now saved to Application Snapshot which can be
opened later - see Issue 235.

Updating summary of this issue to reflect the need for exporting the charts data
into some common data format (probably CSV/XML/HTML similar to Issue 185).
