GC log appender option

We are looking on setting up GC logging with append options such that whenever the IS is restarted, the subsequent GC log information/data is appended to the earlier log data.

Is there a JVM option to meet this requirement?

Do you mean verboseGC.log? I don’t think there is a way to append mode by default IS start creates new file.

Yes. and thank you for your response.
We are trying to figure out some means for achieving this.
