Standard solution would be grafana + Prometheus on one server and a node exporter running on each pi. You then register the node exporters in Prometheus and use that as a data source for grafana. There you build a dashboard showing whatever metrics you want. It can also show some information about the Docker socket, like number of running/stopped containers and such.

Second for Netdata for the temps and load info, portainer for docker monitoring. Netdata gives you more real time info than even glances. Portainer is an easy way to look at logs and such, I don’t use it to manage, prefer command line for that. Netdata we’ll give you some docker info, but not logs.

I use netdata, it's quick and easy, but I don't think it monitors docker containers specifically.

Grafana, influxdb, telegraf agents. Easy to setup. Barely any configuration required. Everything you asked for in the default telegraf agent config. There are dashboards with plenty of examples on grafanas website.

netdata is easy to set up and detects a lot of things on it's own like databases and ntpd and...

I didnt see it recommended yet, UptimeKuma is really simple if you just want to monitor the basics like if a url works or ping, tcp, etc without an agent.

It doesn't do CPU/memory style metrics, but I find myself checking it more often because of how simple it is.

I'm suggesting Homepage for someone for the second time.

I'm kind of loving Zabbix, but not sure if it's the right solution for your needs. I'd say it would definitely work, but does take a bit of setup initially. This article is interesting, and seems to have a lot of what you want. Not sure if you want to do all of this. https://opensource.com/article/23/3/build-raspberry-pi-dashboard-appsmith

Zabbix can do everything you’re asking and can be connected to Grafana if you want custom visualisations. Most importantly, it contextualises what you need to know on the dashboard, as in it only tells you about things that require your attention.

You’re of course able to dive into the data and look at raw values or graphs if you wish, and can build custom dashboards too.

I’ve used it in both home lab and production scenarios monitoring small to mid size private clouds, including windows and linux hosts, docker, backups, SAN arrays, switches, VMware vSphere, firewalls, the lot. It’s extremely powerful and not terribly manual to set up.

If metrics is all you want and aren’t too fussed on the proactive monitoring focus, Netdata is a great option for getting up and running quickly.

Glances should be right up your alley.

I don't use Docker, so this may not help you, but I find bpytop and ssh works just fine. :)
