 We currently have a metrics-specific Nagios host that we want to shut down
 soon. One of its checks is to see whether CollecTor's files are becoming
 unavailable or stale. This check is not easily transferable to Tor's
 Nagios host, because it depends on a code base that is not being
 maintained anymore and that we want to deploy on Tor's Nagios host. That's
 why I rewrote this check in a simple Python script to be deployed on Tor's
 Nagios instance.

 Questions:

  - anarcat and/or weasel: do you have any concerns about deploying this
 check in Tor's Nagios host alongside the
 [https://gitweb.torproject.org/admin/tor-nagios.git/tree/tor-nagios-
 checks/checks/tor-check-onionoo Onionoo check]?

  - irl: do you spot any checks in this Python script that are way off, or
 other checks that are missing?

  - atagar, other Python people: do you mind reviewing the Python code for
 general code improvements? The goal is to have a single, self-contained,
 easy-to-read Python script that produces just the data we need for Nagios
 to send out alerts.
