One shard consumes higher memory

Ops and Admin Sharding
1

Hi,

According to MongoDB memory utilization in cluster environment.
In our environment has 3 config nodes and 3 shard nodes.
We found Node4 in Shard nodes consume memory higher than aside nodes (Node5 and Node6 but Database Active on Node5).

Node4
Node4828×338 29.4 KB

Node5
Node5830×337 29.9 KB

Node6
Node6824×334 27.3 KB

Could you please help us to check which command to review which thing drain memory from non active node?

Best regards,
Jeans

Hi @Jumphol_Buntuek,

Welcome to MongoDB community!

Best way to clear memory of a secondary is to reboot it.

However, to understand what consume memory you will need profiling tools (ops manager/mongotop) and best is to have a support engineer from Mongo to analyse it.

However, this is done via a support subscription and not through this community forum.
