I have supplemented [http://hack.rs/cacti/graph_view.php?action=tree&tree_id=1 the Cacti graphs] that we have for LHS bandwidth and power with [http://hack.rs/cacti/graph_view.php?action=tree&tree_id=5 metrics] that provide insight to the growth of our community and organisation over time.


Phase 1 is complete and we now [http://hack.rs/cacti/graph_view.php?action=tree&tree_id=5 chart the following]:
To chart the metrics various bits of data are exposed in a Cacti friendly way.
* Number of members
* Wiki activity
* Mailing list activity


Later I'd like to investigate:
==Metrics==
* Website visitors and/or page impressions
===Number of members===
* Space occupancy


==In progress==
We may have to wait 12 months before it becomes interesting.
 
====Space occupancy====
I have located two Laser Diode Retroreflective Sensors in our stores which I intend to use to monitor space occupancy by having the beams cross the main doorway. The beams will be staggered so that direction (arriving, leaving) can be determined by the order in which the beams are broken. I was thinking of mounting them at waist height.
 
* This will probably get caught out by clusters of people: --[[81.105.17.61]]
** We only need an approximate count
** The doorway is narrow so it's unlikely that two peoples steps will overlap, if they do - see point above
** Most of the time people won't arrive in clusters
* Can we detect some other event such as the door opening after a prolonged lights-out period to force the count to zero? --[[81.105.17.61]]
** Yes, we can fuse the sensor data with the door/lights data if  we get large amounts of drift - but I don't plan to just yet
 
These sensors appear to be in working order. They'd should be safe to use below child-head height. They were manufactured in 1996 and use a Class II laser rated at 3mW with a wavelength of 655-670nm ([[Media:Banner-q45bb6ll.pdf|datasheet]]).
 
The model number is: Q45BB6LL
 
'''WANTED:''' reflectors for these sensors.

====Website visitors and/or page impressions====
The main site and the Wiki use Google Analytics and this has an API. This [http://code.google.com/apis/analytics/docs/gdata/gdataCommonQueries.html documented method] looks promising:

LHS Graphs and Visualizations


Members Elliot
QR code

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

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

Space occupancy
