rs.printReplicationInfo()¶: New in version 2.6.

Prints a formatted report of the replica set member’s oplog. The displayed report formats the data returned by db.getReplicationInfo(). [1] The output of rs.printReplicationInfo() is identical to that of db.printReplicationInfo().

Note

The rs.printReplicationInfo() in the mongo shell does not return JSON. Use rs.printReplicationInfo() for manual inspection, and db.getReplicationInfo() in scripts.

Output Example¶

The following example is a sample output from the rs.printReplicationInfo() method run on the primary:

configured oplog size:   192MB
log length start to end: 65422secs (18.17hrs)
oplog first event time:  Mon Jun 23 2014 17:47:18 GMT-0400 (EDT)
oplog last event time:   Tue Jun 24 2014 11:57:40 GMT-0400 (EDT)
now:                     Thu Jun 26 2014 14:24:39 GMT-0400 (EDT)

Output Fields¶

rs.printReplicationInfo() formats and prints the data returned by db.getReplicationInfo():

configured oplog size: Displays the db.getReplicationInfo.logSizeMB value.
log length start to end: Displays the db.getReplicationInfo.timeDiff and db.getReplicationInfo.timeDiffHours values.
oplog first event time: Displays the db.getReplicationInfo.tFirst.
oplog last event time: Displays the db.getReplicationInfo.tLast.
now: Displays the db.getReplicationInfo.now.

See db.getReplicationInfo() for description of the data.

[1]	If run on a slave of a master-slave replication, the method calls `db.printSlaveReplicationInfo()`. See `db.printSlaveReplicationInfo()` for details.
