Re: Nodetool info for heap usage


The nodetool output should be accurate and reliable. 

But using nodetool command for monitoring is not a very good idea.
Nodetool has its own resource overhead each time it is invoked.

You should ideally use a standard monitoring tool/method.

Hi All,

Is nodetool info information is accurate to monitor memory usage, intially with 3.1.0 we had monitoring nodetool infor for heap usage and it never reported this information as high,after upgrading to 3.11.2 we started getting high usage using nodetool info   later upgraded to 3.11.3 and same behaviour.
Just wanted make sure if monutoring heap memory usage via nodetool info correct or its actually memory leak issue in 3.11.2 anf 3.11.3?
