Hello,

I had a problem monitoring my cluster with Datadog. The metrics jvm.mem.pools.young.max and jvm.mem.pools.survivor.max return a zero. The metrics for the pool old and the used mem work.

I did check the stats using the API \_nodes/{node\_name}/stats/jvm and the max and peak memory of the pools young and survivors are zero.

```auto
           "pools" : {
                 "young" : {
                   "used_in_bytes" : 49283072,
                   "max_in_bytes" : 0,
                   "peak_used_in_bytes" : 634388480,
                   "peak_max_in_bytes" : 0
                 },
                 "old" : {
                   "used_in_bytes" : 341487616,
                   "max_in_bytes" : 1073741824,
                   "peak_used_in_bytes" : 558934016,
                   "peak_max_in_bytes" : 1073741824
                 },
                 "survivor" : {
                   "used_in_bytes" : 1559376,
                   "max_in_bytes" : 0,
                   "peak_used_in_bytes" : 48765200,
                   "peak_max_in_bytes" : 0
                 }
               }

```

Do you know what could be the cause of this metrics ?

Thanks
