chiennd / pingprom

Quick start to Monitoring Web services with Prometheus

GOAL

Implement Pingdom type functionality with https://prometheus.io/ with least LOC possible.

wc -l *.{yml,service} prometheus/* | tail -n1
 181 total

• Monitor lots of Websites: foo.example.com, bar.example.com, google.com ....
• Email when site goes down with alertmanager & AWS SES
• Graph history of outages with grafana http://0.0.0.0:3000

Features:

• Keeps upto date between reboots
• Containerized

Setup

Assuming you are sshing to a CoreOS machine. Basically "pingprom" requires systemd & Docker.

ssh core@ip
git clone https://github.com/kaihendry/pingprom.git
cd /etc/systemd/system
for i in ~/pingprom/*.service; do echo sudo ln $i; done
echo sudo systemctl start $(for i in ~/pingprom/*@.service; do echo $(basename $i .service)$USER; done)
for i in ~/pingprom/grafana.service; do echo sudo systemctl start $(basename $i .service); done

Now you need to systemctl status or journalctl -u alertmanager@${USER}.service -f to debug the failing ones and once everything looks OK.
