These are not intended to be final tools for production use, but rather starting points for developing your own tools or your own approach. The second piece takes two or more of these collections and performs a statistical analysis on them and creates a report.
The first one just walks a file tree and gathers metadata. I chose to divide the tool into two pieces. My goal is to help you learn a bit about how important metadata of your metadata can be. Therefore, I decided to write my own tools so that I can understand a bit more about my data. These tools, while providing some information, didn’t provide everything I wanted in a way that was useful to me. For example, fsstats is a Perl script that walks file trees and gathers some file system information and presents it to the user with a breakdown of the file data. There are some open-source tools that might help as well. But it can’t describe everything and isn’t flexible enough (plus it doesn’t do non-Windows file systems).

For example, spaceobserver can provide a great deal of metadata information about Windows file systems with the ability to sort it and view it. There are some commercial tools that can do some of this. Maybe once a quarter or so you can do a quick presentation of the information? Therefore, it is a good idea to present this information (trends) to management over time. I would like to have some idea that this request is coming so I can prep my management and also prep the funding channels. Plus, if I were responsible for the purse strings for new storage I would not like to be blind-sided with such a request at the last minute. If you want a faster storage solution, can you show why you need one? Maybe you could show that you have a large number of files, lots of them are really small or really large, etc.Who has the oldest files? (histogram by user and/or group).How much “old” data is there? (Maybe create a histogram showing the age of the files.).For example, a simple chart that could illustrate which user or group of users is consuming the data the quickest is important. How quickly is the capacity is being consumed? Be sure to show this with some detail (not just a global view).A friend of mine calls it “showing your math.” If you are the administrator you will need to be able to present some understandable and useful information. That means they need to explain what’s going on with the storage. I don’t know about you, but I would want them to explain why. An admin or a user comes to you and says they are running out of space or that the performance of the storage is slow and they need new storage. Suppose you are responsible for the budget for data storage. Gathering the information about the files on a file system, that is, gathering metadata about the metadata, is a critical-and very neglected-task in the storage world.

Quick questions: Can you quickly tell me the average file size on your storage system? Can you tell me the average file age?īeing able to answer these questions quickly can help you determine if you need new storage, what type of storage you need, and if you need to archive or move old data off your system, to something cheaper or perhaps just get rid of it (I know, heresy, right?). This information can tell you a great deal about what’s happening with your data. But how about metadata about metadata (data about data about data)?Īctually this is an important topic-understanding and monitoring how and when files are created, used, modified and removed. You may have heard that metadata is data about data (if that makes any sense).
