Nagios Twitter Hashtag Graphing

Nagios Twitter Hashtag Graphing (Twitter is a registered trademark of Twitter, Inc.) ============================ (c) 2016 Nagios Enterprises, Inc. Bryan Heden - bheden@nagios.com ============================ - I've compiled the README into sections based on questions that you may ask yourself after having downloaded this bundle of scripts WHAT IS IT? ============================ - It's a Twitter tweet data aggregator/graphing utility WHAT DOES IT DO? ============================ - One script creates a local database to store some information - One script connects to Twitter's Streaming API with credentials you supply and listens to incoming tweets based on search terms you define - One script parses that tweet data and checks where it came from - The last script is a Nagios plugin that converts all that data into a beautiful graph WHY WOULD YOU MAKE THAT? ============================ - We specifically wanted to correlate hashtag usage by US State during the week directly before the 2016 Presidential Election WHY DID YOU SHARE IT? ============================ - We thought maybe you'd like to do something cool like that, too OK, OK - HOW DO I DO IT? ============================ *** NOTE: This isn't exactly easy, but trust me it is worth it :) - You're gonna need a bit of software installed. If you're on CentOS, the following lines should suffice: yum install -y python-pip python-devel openssl-devel MySQL-python libffi-devel pip install tweepy pyopenssl *** NOTE: The previous lines were only tested on CentOS 6. Your mileage may vary - You'll need somewhere to put the scripts. My suggestion is under /tmp/twitter *** NOTE: The cron file is based on you using the /tmp/twitter location. If you decide on somewhere else, make sure you update the cron file - You need to set up the MySQL Database. Create your database mysql < twitter.sql - And then set up your credentials and make sure you update each of the scripts: check_tweets.php grab_tweets.php streaming_twitter.py - You'll need the Nagios plugin in your plugin directory. It is likely in /usr/local/nagios/libexec cp check_tweets.php /usr/local/nagios/libexec chown nagios:nagios /usr/local/nagios/libexec/check_tweets.php chmod +x /usr/local/nagios/libexec/check_tweets.php - You'll need a command definition in your Nagios configuration file: define command { command_name check_election_tweets command_line $USER1$/check_tweets.php $ARG1$ $ARG2$ $ARG3$ $ARG4$ $ARG5$ } - You need to get your Twitter API Credentials. That is a little out of scope for this document, but going to http://dev.twitter.com is a good start. You'll need an app, then go to the app and select "keys and access tokens" Once you have your access data, make sure to update the streaming_twitter.py file with your credentials - You need to put the cron where it can be picked up. cp cron /etc/cron.d/twitter.cron - Now, you just need to create a Host and some Services so you can graph your data. That should look something like: define service { host_name Election Tweets service_description Ohio Tweets use generic-service check_command check_election_tweets!-l "Hashtag1" -t "hashtag1"!-l "Hashtag Group1" -t "hashtag2,hashtag3"!-s oh -i 300!!! initial_state o max_check_attempts 5 check_interval 5 retry_interval 1 active_checks_enabled 1 check_period 24x7 notification_interval 60 first_notification_delay 0 notification_period 24x7 notifications_enabled 0 register 1 } - That should do it! - If you need help, you can reach out to me at bheden@nagios.com
