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.
"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
