Most of you might find these names similar to two popular Unix commands, iostat
and top
. For MongoDB, mongostat
and mongotop
are two utilities that do pretty much the same job as the two Unix commands, and there is no prize for guessing that these are used to monitor the Mongo instance.
In this recipe, we will be simulating some operations on a standalone Mongo instance by running a script that will attempt to keep your server busy; then, in another terminal, we will be running these utilities to monitor the db
instance.
You need to start a standalone server listening to any port for client connections; in this case, we will stick to the default 27017
. In case you are not aware of how to start a standalone server, refer to the Single node installation of MongoDB recipe in Chapter 1, Installing and Starting the MongoDB Server. We also need to download the KeepServerBusy.js
script from the book's website and keep it handy for execution...
