Example config:
storage:
dbPath: "/var/lib/mongodb"
directoryPerDB: true
engine: wiredTiger
indexBuildRetry: true
syncPeriodSecs: 60
journal:
enabled: true
wiredTiger:
engineConfig:
cacheSizeGB: 4
directoryForIndexes: true
Sets the 37G for the cache_size (it should be 4GB):
2016-01-04T20:39:08.518+0200 I STORAGE [initandlisten] wiredtiger_open config: create,cache_size=37G,session_max=20000,eviction=(threads_max=4),config_base=false,statistics=(fast),log=(enabled=true,archive=true,path=journal,compressor=snappy),file_manager=(close_idle_time=100000),checkpoint=(wait=60,log_size=2GB),statistics_log=(wait=0)
Startup option --wiredTigerCacheSizeGB=4 works well and sets the cache_size correctly:
