I’ve got a lot of services, some in docker, some in LXC or a VM in proxmox. Currently I’ve got no monitoring service. Recently a service went down and I didn’t notice for quite a while so now I’ve got a bunch of missing data. What monitoring tools do you all use? Looking for something that works with docker and plain Linux CTs/VMs and can notify me if a website is down, docker container crashed, VM is offline, etc.

and as a bonus feature something that I can run on two machines so if an entire machine dies, the other will notice and I’ll still receive a notification.

notification can be anything, email, sms, push, etc.

UptimeKuma is what I use; it'll watch tcp connections, docker containers, websites... whatever. And the notifications are pretty comprehensive and probably cover anything in 2023 would want to be using.

I use Uptime Kuma too in my VPS and I monitor it with Node Red at home (that is monitored by Uptime Kuma! 😁) So if anything goes down (monitoring tool too) I receive alerts. Both of them send me alerts with NTFY.

[–] velocidapter@lemmy.world 2 points 1 year ago

+1 for Uptime Kuma. Dead simple to set up and configure, and it has alert support for dozens of services.

I administer a large Zabbix environment in my day job, and while it's not complicated to get set up, it's overkill for simple up/down service monitoring.

I use:

  1. Monitoring server - prometheus
  2. Alert manager for prometheus - alertmanager. You can write any triggers here.
  3. Web UI for prometheus - Grafana
  4. Exporters for prometheus - node-exporter, blackbox-exporter, mysql-exporter, psql-exporter etc. You can find exporter for everything you need.
  5. Some services native support pormetheus. Docker for example: https://docs.docker.com/config/daemon/prometheus/

If you whant cluster you can install thanos on prometheus.

I'd like to explore Prometheus (I've never used it). Right now I use InfluxDB to store some data (ping times, temperature, servers load, etc.) can Prometheus read those values and react if something is off or should I store everything twice?

[–] nitrolife@rekabu.ru 3 points 1 year ago (1 children)

prometheus use own time series database. you can connect influxdb to grafana and send alarms from grafana, but alertmanager better i think. node-explorer can collect all this data (sensors, VM/PC load etc.)

[–] peregus@lemmy.world 2 points 1 year ago* (last edited 1 year ago) (1 children)

I've never used alerting in Grafana, how do they work? Is it possible to get alert if a ping is higher than xx for a period of time? What are alertmanager and node-explorer? Plugins or standalone tools? Sorry for all the questions! 😁 And thanks for the info!

[–] nitrolife@rekabu.ru 1 points 1 year ago (1 children)

Grafana sends an email screenshot of the graph when an event is triggered on the graph. You can see alerts part on any graph for understand.

[–] peregus@lemmy.world 1 points 1 year ago

You know that I've never knew about that? I've just set it up! Thanks!!!

If you strip down monitoring, all you need is a notification if something goes down

I use monocker it monitors status changes on containers and sends a notification when one happens

Thats all

[–] exi@feddit.de 3 points 1 year ago (1 children)

For a handful of servers, try zabbix. Every distribution has a packaged zabbix agent. It has everything: web ui, a way to Auto discover things with a bit of setup, nice graphs, alerting, LDAP User Management if you need it, a way to define per person/group alerting/notification schedules. And the community is big enough that many common services (fail2ban/postfix/MySQL/etc.) have premade custom monitoring scripts. Adding your own metrics is also very easy.

After years of Nagios use now on Zabbix for 2 years. It's really really great and my favorite monitoring system once you get the hang of it.

But overkill for just some home monitoring imo. I would recommend uptimekuma.

[–] SirMaple_@lemmy.world 2 points 1 year ago

I use LibreNMS and Healthchecks.io. I also use Grafana to display all the important data in a dashboard on a portrait mounted monitor on my desk.

[–] leraje@lemmy.world 2 points 1 year ago

I have Conky on my desktop and do a curl to a known page on my server to monitor if a web service is up every 60 seconds. If it's down, I swap to a blinking animated gif as an icon and play an alert sound.

CheckMK is too complicated for my monkey brain. After a few days of going through docs, I can't even get a log file monitoring going.

[–] dustojnikhummer@lemmy.world 2 points 1 year ago

If all you want is uptime monitoring, Uptime Kuma.

[–] mhzawadi@lemmy.horwood.cloud 1 points 1 year ago

a nagios user here, no pretty charts. Just is it down

[–] tychosmoose@lemm.ee 1 points 1 year ago

Monit works for me. Good basic monitoring solution that can also restart a service/interface.

I also use LibreNMS to do alerting for a variety of conditions (syslog events, sensor conditions, outages and services via nagios). But this is more work to get set up.

[–] vegetaaaaaaa@lemmy.world 1 points 1 year ago* (last edited 1 year ago)

I use netdata (agent only, not the cloud/SaaS stuff) for metrics/charts/health/HTTP checks/alerting, and rsyslog+graylog (or just lnav on small setups) for log analysis. Plus a bunch of other scanners (debsecan, lynis, debsums...)
