Frequently Asked Questions


  1. What does QuotaMon have to offer over other quota monitors?

    The advantages of using QuotaMon are fairly significant:

    Free - Free is always a good thing when it comes to software.

    Low Data Collection Overhead - Data collection occurs once a week, and all of the heavy lifting for data collection is done on the systems where the partitions reside, which isn't that much to begin with.

    File Access Ages - QuotaMon collects information about how recently files have been accessed making removing stale data from your filesystem easier.

  3. Can you control how much data is collected and how long it is kept?


    Controlling how much data is being collected is as simple as removing partitions from the configuration file. As for how long data is kept, that's just a matter of cleaning up old data files, which you can do with cron.
