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.

      +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 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.

    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

    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.

    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.

    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.
