Is there an on-premise, open source option for a monitoring/telemetry platform comparable* to say New Relic or Dynatrace with an approachable query language?
Is Prometheus+Grafana pretty much it?
Simpler the better, approachable for a casual user (i.e. curious non-technical tenants) would be great.
* Caveats for "comparable" apply!
Anyone have any advice on a OPEN SOURCE systems/network monitoring tool that isn't #Zabbix or #LibreNMS ? I'm already running those two.
#Nagios is still "half payware", and I'm at a point in my life where I don't need to be editing 400 different configuration files, one for each server/router/etc., so that's Right Out.
Ideally, it'd auto-discover hosts on the network, present them to me in a list, and allow me to configure them via a web client.. just like Zabbix and LibreNMS do.
Why do I want a third monitoring solution? I have my reasons.
So, anyone have any recommends? I'd like to be able to graph uptime, network traffic, CPU and RAM usage, etc. and do it in pretty graphs. I'd also like to be able to do it without spending
Thanks in advance.
Old PC -> Raspberry Pi Update:
Hardware fully assembled, OS installed, first 24/7 service (Nagios network + host monitoring) migrated.

I used to do stuff like this with #Nagios back in the day. Lots of fun to be had.
New app from @vegantacos that is really useful!!! Get sysadmin alerts directly to your phone with Open Alert Viewer. https://github.com/okcode-studio/open_alert_viewer
This is a brand new project so give it some stars. #sysadmin #prometheus #nagios

I have always found #monitoring tools like #Nagios to be very complicated and difficult to learn. I've tried a few times to write something to fill this role, but never finished, until now. The tools exist now, and I have created Patrolilo, a #Rust program which ingests a simple YAML config file, runs scripts on a schedule, and sends you a notification to your phone if the script fails.

I'm just using it to monitor some services with regularly scheduled `systemctl status` runs.
I shouldn't be *this* pleased that I greatly optimized and simplified my 20 years old #nagios config with service/host templates and host groups. It's boring ancient run-of-the-mill stuff, nothing complicated, but somehow I managed to put it off this long and just copy-pasted the hell out of everything.
3 Easy Steps to Integrate Monitoring Tools for Apache Reverse Proxy Server https://blog.radwebhosting.com/3-easy-steps-to-integrate-monitoring-tools-for-apache-reverse-proxy-server/

Hey #SysAdmin, how do you monitor your servers? For me #PRTG and #Nagios are just too complicated. So i rolled my own: https://github.com/eitch/beacon-agent
Now i monitor CPU, Memory, Dis usage, packages, virtual machines and containers all from one agent, pushing to #UptimeKuma, which in turns uses #Gotify and mails to keep me informed if a server needs investigation.
This keeps me sleeping much better.
I finally got around to upgrade my Nagios Core instance to the latest release (v4.5.5)and they got rid of the new network map! I'm sad to see it go, it was a really nice replacement to their legacy maps.
Improved my #nagios/#icinga plugin for checking the #raspberrypi temperature. Now it works on #openbsd as well as on #linux. Still some sanity checks regarding #bcmtmon needed.

We love open source 
This is why we have opened our Nagios Plugins 
https://github.com/ovh/ovh-nagios-plugins
For now, we have probes to check TimescaleDB and MongoDB.
Soon, we should have one for MySQL including support for Group Replication and Cluster Sets.
And many more in the future 
My little pi running Nagios to monitor work assets (it works just fine) went offline on Thursday. I run to the office today to see what happened. I plug in a monitor and then notice... no network.
Someone unplugged the network cable.
I now have five days of notifications coming into my inbox.
Well, there goes those few hours.
For future reference:CN=Nagios Bind,DC=Example,DC=Com != CN=NagiosBind,DC=Example,DC=Com
