db.printReplicationInfo() (mongosh method)

Definition

db.printReplicationInfo()

Prints a formatted report of the replica set member's oplog. The displayed report formats the data returned by db.getReplicationInfo().

The output of db.printReplicationInfo() is identical to that of rs.printReplicationInfo().

Note

The db.printReplicationInfo() method run in mongosh does not return JSON. Use db.printReplicationInfo() for manual inspection, and db.getReplicationInfo() in scripts.

Output Example

The following example is a sample output from the db.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)

now:                     Thu Jun 26 2014 14:24:39 GMT-0400 (EDT)

Output Fields

db.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.
