Description

Objective¶

We want to have a live update similar to https://status.ungleich.ch/ running on the VPS.
We want to do this via some open source monitoring.
We want to check ping, http and maybe https reachability
The information should be public

Hints¶

~~Checkout on one of our VMs, if opennms allows to create a public interface.~~
~~Checkout the list of systems on https://www.pcwdld.com/linux-network-monitor-software-and-tools#OpenNMS~~
~~Another interesting project that we already have running is smokeping~~
Easiest way, reproduce what we already have:
- setup prometheus
- setup grafana
- setup blackbox-exporter
- create a public dashboard

-> checkout the tools, discuss with me in the chat which one to use

I have setup (prometheus + grafana + blackbox exporter) on debian.sandbox.ahmedbilal.ungleich.cloud

You can see the Grafana at http://debian.sandbox.ahmedbilal.ungleich.cloud:3000

username: admin
password: admin

You can see the Prometheus at http://debian.sandbox.ahmedbilal.ungleich.cloud:9090

What to do next except deploying it to VPS. I assign the DNS name post.ungleich.ch to VPS.

you can also add another name to the VPS like
monitoring.place11.ungleich.ch ;-)

Seems not to be solved:

monitoring.place11.ungleich.ch’s server IP address could not be found.
