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.

Munin plugin example

Setup instructions

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 /etc/munin/plugins/

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.
