Overview

I have supplemented the Cacti graphs that we have for LHS bandwidth and power with metrics that provide insight to the growth of our community and organisation over time.

To chart the metrics various bits of data are exposed in a Cacti friendly way.

Metrics

Number of members

We may have to wait 12 months before it becomes interesting.

This data is stored in an Sqlite database on Turing. See the Schema. It can be queried like so:

 SELECT COUNT(id)
 FROM users
 WHERE subscribed = true;

Cacti runs on babbage but the members database is on Turing. There is a PHP script on Turing to expose the member numbers and then a script on babbage to pull this in with a HTTP request.

Wiki statistics

• We get this using the MediaWiki API:

 http://wiki.hackspace.org.uk/w/api.php?action=query&meta=siteinfo&siprop=statistics&format=xml

It returns:

 <?xml version="1.0"?>
 <api>
   <query>
     <statistics
       pages="759"
       articles="215"
       views="229656"
       edits="7368"
       images="186"
       users="166"
       activeusers="22"
       admins="61"
       jobs="13"
     />
   </query>
 </api>

A Perl script generates the following output for cacti: pages:759 articles:215 views:229656 edits:7368 images:186 users:166 activeusers:22 admins:61 jobs:13
