gcmtest's Introduction
Android app and a script to test the latency of Google Cloud Messaging Steps to Run ------------ 1) Change API_KEY, mysql connection url in server/server.rb 2) cd server && bundle install && bundle exec ruby server.rb 3) Change SENDER_ID in GCMIntentService to your google project id 4) Change STATISTICS_ENDPOINT in GCMIntentService to your IP where the ruby script is running (step 1) 5) Deploy the android app to any number of devices / emulators 6) execute "watch -n 10 'curl -s http://localhost:4567/push'" <-- Pushed a message every 10 secs Queries to get stats: --------------------- 1) Max latencies select post_time, received_time, TIMESTAMPDIFF(SECOND, post_time, received_time) as latency from stats where received_time IS NOT NULL order by latency desc limit 5; Sample Result: +---------------------+---------------------+---------+ | post_time | received_time | latency | +---------------------+---------------------+---------+ | 2012-12-16 23:32:13 | 2012-12-16 23:40:50 | 517 | | 2012-12-18 09:39:28 | 2012-12-18 09:40:51 | 83 | | 2012-12-18 15:02:49 | 2012-12-18 15:03:48 | 59 | | 2012-12-18 15:02:59 | 2012-12-18 15:03:51 | 52 | | 2012-12-18 15:03:10 | 2012-12-18 15:03:54 | 44 | +---------------------+---------------------+---------+ 2) Percentage of notifications received across time of the day select HOUR(post_time) as posted_hour, (count(received_time)/count(*))*100 as percentage_of_messages_received from stats group by posted_hour; +-------------+---------------------------------+ | posted_hour | percentage_of_messages_received | +-------------+---------------------------------+ | 9 | 25.9804 | | 10 | 6.2315 | | 11 | 5.9172 | | 12 | 4.0059 | | 13 | 3.2397 | | 14 | 3.1065 | | 15 | 7.4074 | | 16 | 6.5828 | | 17 | 5.0766 | | 18 | 3.3175 | | 19 | 20.2586 | | 20 | 11.5741 | | 21 | 0.7813 | | 23 | 18.0952 | +-------------+---------------------------------+
