motop 192.168.124.50 192.158.124.51

Actions

q Quit

p Pause

e Explain the query

k Kill operation using "mongo" executable

K Kill operations older than given seconds using "mongo" executable

r Try to reconnect to disconnected servers

R Try to reconnect to all servers

Dependencies

python 2.6 or greater
pymongo 2.0 or greater [1]

[1] http://pypi.python.org/pypi/pymongo/

Configuration (Optional)

Configuration file can be created to /etc/motop.conf.

There can be multiple sections on the configuration. Each section can include these parameters:

address: Address of the server (required)
username: Username to authenticate to the server
password: Password to authenticate to the server
status: Show status (default: on)
replicationInfo: Show replication status (default: on)
replicaSet: Show replica set status (default: on)
operations: Show operations (default: on)
replicationOperations: Show constantly appeared replication operations on the masters and the slaves (default: on)

"DEFAULT" is the special section. Parameters can be set as default in this section.

The names of the sections will be used as server names. These names can alse be used on arguments of the executable.

Example configuration:

[MongoDB01]
address=10.42.2.121
replicationOperations=off

[MongoDB02]
address=10.42.2.122

[MongoDB03]
address=10.42.2.123

[MongoDB04]
address=10.42.2.124
username=foo
password=bar

optimeData KeyError

Hello!

I just read about motop on the mongodb website and wanted to give it a try.

When trying to connect to an internal VM running MongoDB on a non-standard port such as hostname:27108, I get the error below. Not sure if the setup is the reason why it's failing or perhaps a newer version of Pymongo?

me@local ~/g/m/motop> python motop.py

Wrap long queries

Some queries are not displayed because they're too large and db.currentOp() doesn't return them. But all other queries are truncated by the right margin of the terminal. Any chance to wrap the query onto multiple lines? Bonus points for pretty-printing it.

ModuleNotFoundError: No module named 'motop'

Why ?

Add $comment in queries

Would be very useful to debug slow ones

Support sharded enviroments

It would be super cool if motop could be configured to connect to a mongos instance. This way it would be super easy to monitor queries accross a cluster.

Right now it crashes with the following message:

How to designate mongodb port?

How to designate mongodb port?My mongodb is listening on 1234 other than 27017.

Windows compatibility?

Looks like motop needs termios, which doesn't work on Windows.
