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.
Recently I removed all Google Ads from this site due to their invasive tracking, as well as Google Analytics.

PCBWay referral link (You get $5, I get $20 after you've placed an order)
Digital Ocea referral link ($200 credit for 60 days. Spend $25 after your credit expires and I'll get $25!)
Setup instructions
You need CURL, so you might need to install that via your package manager.
Clone the git repository:
git clone git://github.com/RaymiiOrg/munin-plugins.git
Place the plugin file in /usr/share/munin/plugins/, make it executable and
create a symlink in /etc/munin/plugins/
cd munin-plugins
cp logstash-messages-per-hour.sh /usr/share/munin/plugins
chmod +x /usr/share/munin/plugins/logstash-messages-per-hour.sh
ln -s /usr/share/munin/plugins/logstash-messages-per-hour.sh /etc/munin/plugins/logstash
Edit the plugin if your elasticsearch database URL is on another host:
# Edit the following line, and change localhost to what it should be
TOTAL_EVENTS=$(curl -s -k -XGET http://localhost:9200/logstash
Then wait until your munin server has updated, and enjoy.
