This is a simple munin plugin which shows you the amount of log messages your logstash/kibana server receives per hour. It should run on the Logstash host, it gets the data from out the Elasticsearch database.
You need CURL, so you might need to install that via your package manager.
Clone the git repository:
git clone git://github.com/RaymiiOrg/munin-plugins.git
Place the plugin file in
/usr/share/munin/plugins/, make it executable and create a symlink in
cd munin-plugins cp logstash-messages-per-hour.sh /usr/share/munin/plugins chmod +x /usr/share/munin/plugins/logstash-messages-per-hour.sh ln -s /usr/share/munin/plugins/logstash-messages-per-hour.sh /etc/munin/plugins/logstash
Edit the plugin if your elasticsearch database URL is on another host:
# Edit the following line, and change localhost to what it should be TOTAL_EVENTS=$(curl -s -k -XGET http://localhost:9200/logstash
Then wait until your munin server has updated, and enjoy.
