it with other databases.
Utilizing the collStats command
The output of this command is the same as the

collStats
command returns a collection's statistics, such as index size, number of re-
cords, average object size, and so on.
To execute the command, you should first select your database with the
use <dbname>
command and then issue following command:
db.<collection_name>.runCommand("collStats")
The following screenshot shows the output of the preceding command:
Use the preceding command to compare two or more collections' status on a database.
Understanding the serverStatus command
Another useful command to get a report from a database is the
serverStatus
com-
mand. This command represents a complete report from a database, collections, to the
overall status of the database.
For instance, by issuing this command, you can check the uptime of a server and the serv-
er's local time, hostname, engine version, number of current active connections, and so on.
To use the
serverStatus
command after choosing the database, run the following
command:
db.runCommand("serverStatus")
