The off-heap memory is not deallocated - once requested from the OS it will be used by an Ignite node process. So, you can only see it growing as long as the node is storing more data.
Check this documentation section for memory tracking hints: https://apacheignite.readme.io/docs/memory-metrics#section-memory-usage-calculation Plus, try out console.gridgain.com - it's free. - Denis On Fri, Mar 29, 2019 at 3:34 PM scottmf <scott...@gmail.com> wrote: > Hi, > I have a two node cluster with 8GB offheap memory configured on each node. > To monitor my offheap usage I'm checking the > dataregionmetrics.<REGION>.offheapusedsize metric from jmx.
