A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.
For Example
- Service: Dropbox - Alternative: Nextcloud
- Service: Google Reader - Alternative: Tiny Tiny RSS
- Service: Blogger - Alternative: WordPress
We welcome posts that include suggestions for good self-hosted alternatives to popular online services, how they are better, or how they give back control of your data. Also include hints and tips for less technical readers.

This. If you have more servers you can also get them all connected to a single UI where you can see all the Infos at once. With netdata cloud
Just set this up yesterday. I used a parent node and then have all my vms point to that. Took like an hour to figure it out
Hey, did you use the cloud functionality or not? I'm tryna go all local with parent-child kind of capability but so far unable to.
The parent still is visible to the cloud portal. My understanding is the data all resides local, but when you login to their cloud portal, it connects to the parent to display the information. I’m still playing with it to confirm. My parent node shows all the child nodes on the local interface but the cloud still shows them all.

agreed .... BY FAR the fastest. Easiest learning curve as well

I currently use thr classic "Hu seems slow, checks basic things like disk usage and process CPU/RAM usage I'll do a reboot to fix it for now".
This is me. Can't hurt to just do a reboot
Windows Server? )
Netdata, I've meant to look into Grafana but it always seemed way too overcomplicated and heavy for my purposes. Maybe one day, though...
I thought the same thing but it's not bad actually, there are some pre build dashboards you can import for common metrics from Linux, windows, firewalls etc .....
netdata is much better though (IMHO)
I know that it needs a fix when my dad complaining that he can’t watch TV and the rolling door doesn’t open in the morning.
Checkmk (Raw - free version.) Some setup aspects are a bit annoying (wants to monitor every last ZFS dataset and takes too long to 'ignore' them one by one.) It does alert me to things that could cause issues, like the boot partition almost full. I run it in a Docker container on my (primarily) file server.
I use this as well! Works well and has built in intelligence for thresholds.
Use PRTG, up until 100 sensors it’s free.
Best Monitoring tool ever ☝🏻🙂
Glances, uptime-kuma, and back end script that reboots service if down. If it doesn't work I get a notification via gotify. Simple and sweet
None. There is no need for a performance monitor for my home lab. I just have an alert if one of my main three services is down. That is all i need.
I recommend Checkmk. https://checkmk.com/
I second CMK.
A TICK stack is unwieldy, Grafana takes a lot of setup, and all of this assumes you both know what to monitor and get stats on it.
CMK by contrast is plug and play. Install the server on a VM or host, install thr agent on your other systems, and you're good to go.

I just check the proxmox dashboard every now and then. Honestly if everything is working I'm not too worried about exact ram levels at any given moment
Netdata, monitoring a few thousand servers (virtual) that way.
Uptime Kuma and Grafana. Uptime Kuna to monitor if a service is up and running and Grafana to monitor the host like CPU, RAM, SSD usage etc.
Same here, also have some autoscaling mechanisms set up in docker swarm to scale certain services in case the load is high

Nobody mentioned htop 🤔
Just to make sure: You are aware that a search option here exists, yes? And you keep refusing to use it for whatever reason?
I personally use Influxdb , telegraf and grafana
I use checkmk with notifications to a telegram bot
Alerts are much more important than fancy dashboards. You won't be staring at your dashboard 24/7 and you probably won't be staring at it when bad things happen.
Creating your alert set not easy. Ideally, every problem you encounter should be preceded by corresponding alert, and no alert should be false positive (require no action). So if you either have a problem without being alerted from your monitoring, or get an alert which requires no action - you should sit down and think carefully what should be changed in your alerts.
As for tools - I recommend Prometheus+Grafana. No need for separate AletrManager, as many guides recommend, recent versions of Grafana have excellent built-in alerting. Don't use those ready-to-use dashboards, start from scratch, you need to understand PromQL to set everything up efficiently. Start with a simple dashboard (and alerts!) just for generic server health (node exporter), then add exporters for your specific services, network devices (snmp), remote hosts (blackbox), SSL certs etc. etc. Then write your own exporters for what you haven't found :)
One thing about using Prometheus alerting is that it’s one less link in the chain that can break, and you can also keep your alerting configs in source control. So it’s a little less “click-ops,” but easier to reproduce if you need to rebuild it at a later date.
When you have several Prometheus instances (HA or in different datacenters), setting up separate AlertManagers for each of them is a good idea. But as OP is only beginning his journey to monitoring, I guess he will be setting up a single server with both Prometheus and Grafana on it. In this scenario a separate AlertManager doesn't add reliability, but adds complexity.
As for source control, you can write a simple script using Grafana API to export alert rules (and dashboards as well) and push them to git. Not ideal, sure, but it will work.
Anyway, it's never too late to go further and add AlertManager, Loki, Mimir and whatever else. But to flatten the learning curve I'd recommend starting with Grafana alerts that are much more user-friendly.

Rainmeter if it's directly on their desktop/background.
I use Uptime Kuma to monitor particular services and NetData for server performance. I then pipe the alerts through to Pushover
Grafana. Have alerts set up and get data with node exporter and cadvisor with some other containers giving some metrics.
I have alerts setup and they just ping me on a discord server I setup. High cpu and temps low disk space memory things like that. Mostly get high CPU or temp alerts and that's usually when plex does its automated things at 4am.
Prometheus + Grafana, the same I use at my job.
Honestly my load is so light I don't bother monitoring performance. Uptime kuma for uptime, I used to use prtg and uptime robot when I ran a heavier stack before I switched to an all docker workload.
I don't check it all the time like a maniac but I have a glances docker running on my main server.
Glances is really nice. I've been using btop more recently though.
I use Zabbix. Runs fine in a relatively small VM. Easy to write plugins.
libreNMS is the tool I use, and it connects to systems primarily via SNMP (use v3, do not use v1 or v2c).
Influx/telegraf/grafana stack. I have all 3 on one server and then I put just telegraf on the others to send data into influx. Works great for monitoring things like usage. You can also bring in sysstat.
I have some custom apps as well where each time they run I record the execution time and peak memory in a database. This lets me go back over time and see where something improved or got worse. I can get a time stamp and go look at gitea commits to see what I was messing with.
If one of my users ever complained about anything I would possibly look into it, otherwise it all works so I don't waste life energy on that.
TICK stack is the only answer
It is bit difficult at start, but really in the end you can monitor and get notification on anything thats happening on your system.
When the fan gets loud enough to hear, I'll check it :P
