Instance Logs
- Mongo Instance logs are located at DSOURCE_MOUNT_PATH/logs ( for dSource )
- Mongo Instance logs are located at VDB_MOUNT_PATH/logs ( for VDB )
- Delphix logs names are in format dlpx.sNmM.port.mongod.log
where
N = 0,1,2,3,… [ Shard Number ] [ Always 0 for any non-sharded implementation ]
M = 0,1 OR 2 [ Member Number ]
port = port number of mongo instance.
Note : Most of the mongo related errors are always hidden in logfile for the mongo instance. Please examine logs under DSOURCE_MOUNT_PATH/logs and VDB_MOUNT_PATH/logs for further investigation.
MongoSync
- MongoSync logs are located at DSOURCE_MOUNT_PATH/.delphix/mongosync/mongosync.log
- Oplog sizing for staging database: It can be decided as per the MongoDB documentation
- If memory utilisation is higher, the kernel running on staging host might kill MongoDB processes to recover memory where we could see Out of Memory error in the syslogs of staging host. To avoid this, we could limit the memory utilisation of MongoDB processes by tuning wiredTigerCacheSizeGB in the “Set Parameters” section of the “Add dSource ” UI.
