db.serverStatus().wiredTiger shows a log of things.
But I can not find any of this item in the document.
I have no idea which of them is useful,or what`s the meaning of them.
Like the return of db.serverStatus().wiredTiger.cache
{ "tracked dirty bytes in the cache" : 25741348, "tracked bytes belonging to internal pages in the cache" : 55454176753, "bytes currently in the cache" : 3430851169, "tracked bytes belonging to leaf pages in the cache" : NumberLong("9223372036854775807"), "maximum bytes configured" : 4294967296, "tracked bytes belonging to overflow pages in the cache" : 0, "bytes read into cache" : NumberLong("1369313451711"), "bytes written from cache" : 703660481848, "pages evicted by application threads" : 82877, "checkpoint blocked page eviction" : 9039, "unmodified pages evicted" : 50377821, "page split during eviction deepened the tree" : 0, "modified pages evicted" : 22454998, "pages selected for eviction unable to be evicted" : 3316349, "pages evicted because they exceeded the in-memory maximum" : 17, "pages evicted because they had chains of deleted items" : 362314, "failed eviction of pages that exceeded the in-memory maximum" : 34109, "hazard pointer blocked page eviction" : 2772938, "internal pages evicted" : 2167450, "maximum page size at eviction" : 15481714, "eviction server candidate queue empty when topping up" : 483082, "eviction server candidate queue not empty when topping up" : 853628, "eviction server evicting pages" : 6195617, "eviction server populating queue, but not evicting pages" : 1000198, "eviction server unable to reach eviction goal" : 11, "pages split during eviction" : 266859, "pages walked for eviction" : 31445786857, "eviction worker thread evicting pages" : 69577117, "in-memory page splits" : 8, "percentage overhead" : 8, "tracked dirty pages in the cache" : 618, "pages currently held in the cache" : 116937, "pages read into cache" : 73221060, "pages written from cache" : 49983684 }
or db.serverStatus().wiredTiger.cursor or something else
Hope for your return
