I’m hoping to find something that:

  • has a nice dashboard
  • is quick and simple to install
  • is very lightweight and unobtrusive
  • can send alerts via http request

    Netdata is exactly what you’re looking for. It’s basically an all in one monitoring and and alerting suite that collects and analyzes data, and provides a gorgeous web dashboard for you to view.

    You can also manually replicate this using Prometheus, Grafana and other tools, but that requires a much bigger effort to set up.

    Edit: There’s a public demo instance where you can try everything out: https://frankfurt.netdata.rocks/

      I think they went to 5 nodes max on the free version as of the last patch. That’s damn near useless.

        Is that just for the centralized dashboard portion? I tend to use each instance of it standalone, and primarily for the email alerts.

          I believe so. I imagine the next stage of the enshittification will be to force those standalones to register with a portal account.

    While I use LibreNMS as it uses SNMP for monitoring (which is pretty much available everywhere), I don’t believe it has http alerts, but I know for a fact that it can send Telegram messages.

    I just see if it works when I need it. If I’m at home it works. If I’m at work it may work. If I’ve left to travel it’s 95% definitely down and cannot be fixed. This works well!

    • Base ansible role installs Prometheus node exporter, configured with the text file collector
    • VM automations push DNS records so that the Prometheus dns-sd automatically discovers them
    • Ansible roles for add Cron jobs that generate metrics for specific systems and dump them for the text file collector
    • Grafana for dashboards
    • Karma as a UI in front of Prometheus alert manager

        • https://github.com/prometheus/node_exporter?tab=readme-ov-file#textfile-collector - which makes node exporter watch a specific directory for files that contain metrics, then re-export them back to the central Prometheus server
        • Some systems have their own metrics endpoints - instead of getting Prometheus to scrape these directly I set up a Cron job to curl these into files for node exporter - this means I don’t need extra config in Prometheus to find the endpoints, and don’t need to mess with firewall rules
        • Other systems don’t directly expose metrics in a format Prometheus can use - in this case I will write/find a script that can do the conversation, then either set it up to write the metrics file directly and run it on a Cron, or run it as a service and another Cron job to do the scrape

    I personally use CheckMK.

    • Offer a free “Raw” version.
    • Can be deployed with docker.
    • OSS

    One thing is that it can be a lot to take in at first and took me a while to get used to it.

      CheckMk user here via omd.

      I’m looking for something else after the upgrade.

      1. Black interface isn’t pretty for me and the old interface was “meh too hard so we ditched it”.

      2. One half of the project split has a shit supply chain and just doesn’t meet the bar for upgrade requirements.

      3. The other half of the project split is a mess to config in an automated desired-state setup. It’s all edge-triggered manual bullshit. NO. ENOUGH.

      I miss 1.2 .

    Nagios. It does depend on what you mean by monitor though. Nagios is good at telling you that “service A on host B” is down" but less useful for looking at things like performance trends. I particularly like being able to setup dependencies between services, so I get the alert for the root cause, and not all of the services that have gone down because of it.

    Hello,

    I’m still using Nagios here. And for the availability of the services I’m using uptime-kuma (in a docker).

    Zabbix is pretty quick and easy. Many different services built in for sending notifications, along with your own custom (including webhooks). Fully customizable dashboard as well so you can add whatever you want/need at a glance.
