1>How can I run the equivalent using pymongo?
cfg = rs.conf()
2>Using PyMongo, how can I get the details of other replica sets CLI output in the created clusters . (Note:I have already successfully created cluster.Just I am writing a python script in primary to check the outputs of
db.printSlaveReplicationInfo() in all the replica sets inside cluster and parse the output.)
Any help on this regard is greatly appreciable.
The replica set configuration is stored in the "local" database in a collection called "system.replset" so the equivalent of
rs.conf() would be
db.system.replset.findOne() when db is
local or its equivalent
find_one() in Python.
db.printSlaveReplicationInfo() is a big more involved, but you can get all of that information in the
local database as well.
It may be easier to get it via admin database command
replSetGetStatus which returns a document containing oplog information for each member of the replica set, along with other details. Python MongoDB driver
pymongo provides a method to run commands, so you can run it against the
admin DB and parse out the output for information about where each member of the replica set is relative to the primary.
