There are 136 attributes providing different information for db.serverStatus().wiredTiger.cache
But, mongodb documentation link https://docs.mongodb.com/manual/reference/command/serverStatus/#serverstatus.wiredTiger.cache has information only for < 10 attributes.
I tried to google, but, no luck. If you are aware of a link, please share.
I need these detais for monitoring purposes… I would like to capture atributes like
wired tiger cache - currently used bytes, free bytes
Mongod filesystem cache - currently used bytes, free bytes
