fintop

A top-like utility for monitoring Finagle services.

fintop is a command-line program that gathers and prints abbreviated monitoring information on local processes running Finagle clients or servers. It is loosely modeled on top, but doesn't strictly adhere to top-style output.

For example, given two Finagle servers running locally, running fintop could look like this:

$ fintop
Finagle processes: 2, Threads: 44 total, 30 runnable, 14 waiting

PID     PORT   CPU   #TH   #NOND  #RUN   #WAIT   #TWAIT   TXKB       RXKB
14909   1110   4.0   22    1      15     4       3        351        363
14905   9990   4.0   22    1      15     4       3        325        823

For more details on usage and explanations of all abbreviations used in the output, run fintop -h.

fintop is distributed as an executable Ruby gem. To install it from RubyGems.org, simply run gem install fintop.

To install fintop locally from source, clone this repository and run rake install from within the repository's root directory.

fintop currently prints static output rather than continously refreshing. In order to achieve periodic monitoring akin to top, combine it with the watch command:

$ watch fintop

Mac users: OS X does not ship with a built-in watch binary but one can be installed via Homebrew by running brew install watch.
