Hi,

Has someone experiences in visualizing the java garbage collector log?
Is there any tool or trick to create a diagram?

Here are two lines of the log

238371.981: [Full GC 238371.982: [Tenured: 122764K->122775K(218740K),
0.1597260 secs] 122829K->122775K(243444K), [Perm : 12223K-

>12223K(16384K)], 0.1599150 secs]

238404.485: [GC 238404.485: [DefNew: 21614K->2687K(24704K), 0.0287660
secs] 144390K->128876K(243444K), 0.0289980 secs]

I would imagine you would want some ordinary line graphs. To get them
use a graphing package and write a little java program to extract the
data of interest.
