Initially I'd like to chart the following:
To chart the metrics various bits of data are exposed in a Cacti friendly way.
* Number of members
* Wiki activity


Later I'd like to investigate:

* Website visitors and/or page impressions

To chart the initial metrics various bits of data will need to be exposed in a Cacti friendly way. I need help in getting access to these data sources so that I can write the various data input methods.

And for pending users:
Cacti runs on chomsky but the members database is on Turing. There is a PHP script on Turing to expose the member numbers and then a script on chomsky to pull this in with a HTTP request.


  SELECT COUNT(id)
''Code:'' https://github.com/londonhackspace/monitoring
  FROM users
  WHERE subscribed = false;
 
To import historic data into rrdtool we can look at the date of members first payments - I probably won't bother with this:


  SELECT t1.timestamp, COUNT(t1.id)
''URL:'' http://london.hackspace.org.uk/member_stats.php
  FROM transactions t1
  LEFT JOIN transactions AS t2 ON t1.user_id = t2.user_id
  AND t1.timestamp > t2.timestamp
  WHERE t2.timestamp IS NULL
  GROUP BY t1.timestamp;


This bash script will generate the following output for cacti: '''<tt>subscribed:136 pending:2</tt>'''

LHS Graphs and Visualizations

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

Code: https://github.com/londonhackspace/monitoring

URL: http://london.hackspace.org.uk/member_stats.php

IRC statistics

See project: ircensus

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

Code: https://github.com/londonhackspace/monitoring

Mailing list activity

  • My thanks to JamesG for his assistance and '78.86.160.161' for the original idea. We poll and scrape the groups page for members and and message count.
 http://groups.google.com/group/london-hack-space

We have a script that outputs: members:693 messages:3123

Space occupancy
