Key requirement is that it can check on both IP4 and IP6 and alert if either is down. (We do this with a [https://prometheus.io/](https://prometheus.io/) self hosted system but we’d like a backup. I can write-up details of our Prometheus setup if anyone likes?) ---

We use [Icinga](https://icinga.com/) and [Ansible](https://git.coop/webarch/icinga-network#icinga-monitoring-network) to configure and deploy it. ---

Agile Collective use [Icinga2](https://icinga.com/docs/icinga-2/latest/doc/01-about/) for service and host monitoring. Which is highly configurable and will certainly monitor IPv4 and IPv6 addresses. It’s also quite complex to setup. We also use [PHP Server Monitor](https://github.com/phpservermon/phpservermon) for basic uptime stats and alerting. It looks like it will do IPv4 and IPv6, but you might need to monitor IP addresses rather than domains. ---

We use uptime kuma, really useful and plugins for lots of different notification services. [GitHub - louislam/uptime-kuma: A fancy self-hosted monitoring tool](https://github.com/louislam/uptime-kuma) ---

UptimeRobot don’t do IP4/6. It’s on wishlists but nope. Shame, I’d just pay them if they did. ---

So it looks like we are all good self-sufficient people and self-host 🙂 Well we are quite happy with our Prometheus server - as well as blackbox for uptime checks we also use the node exporter heavily for Linux hosts and some of the app exporters. We have even written a custom exporter into our own app so Prometheus could monitor things. I would have liked a third party external service tho as a backup. Oh well. ---

All the Ansible we have written for setting up a Icinga monitoring service is public has been released under the GPL and can be accessed via the link I posted above. We would also be happy to provide Icinga as a service including the install, configuration and management of it if required, we would make the git repo available to the client so they can also update the config if they want to, there is a fairly simply YAML dictionary per host, you simply add a host and run [a Bash script](https://git.coop/webarch/icinga-network/-/blob/master/icinga.sh) to update the config, this is the config we have for this Discourse server: ```yaml cotechforum.webarch.net: icinga_parent_node: "{{ icinga_master_node }}" icinga_check_commands: apt: disk_root: command: disk args: disk_partitions: / disk_mountpoint: true disk_wfree: 20% disk_cfree: 10% dns: load: args: load_percpu: 1 ping: ssh: swap: systemd: http: command: http args: http_vhost: community.coops.tech http_uri: / http_expect_body_regex: "Cooperative Technologists Community Discourse Forum" http_port: 443 http_ssl: 1 ``` All the elements below `icinga_check_commands` are [check commands](https://icinga.com/docs/icinga-2/snapshot/doc/10-icinga-template-library/#plugin-check-commands-for-monitoring-plugins) from the [Icinga Template Library](https://icinga.com/docs/icinga2/latest/doc/10-icinga-template-library/) and this is how it looks in the web interface: ![Screenshot 2023-03-30 at 09-49-52 cotechforum.webarch.net Hosts Icinga Web](https://community.coops.tech/uploads/default/original/2X/c/cfe6cbaad241ad340b03cdb50b39bc9d15679859.png) The above example has an agent running on the server being monitored, this is required for disk, cpu etc, but servers can also be monitored without clients, for example this is the config we use for a Mailcow server that doesn’t have an agent running on it: ```yaml email.example.org: icinga_parent_node: "{{ icinga_master_node }}" icinga_check_commands: ping: ssh: mailcow: command: http args: http_ssl: 1 http_string: "mailcow UI" http_uri: / sogo: command: http args: http_ssl: 1 http_string: "SOGo Groupware" http_uri: /SOGo/ imap143: command: imap imap993: command: imap args: imap_port: 993 imap_ssl: 1 pop110: command: pop pop995: command: pop args: pop_port: 995 pop_ssl: 1 smtp25: command: smtp args: smtp_starttls: 1 smtp465: command: ssmtp args: ssl_port: 465 smtp587: command: smtp args: smtp_port: 587 smtp_starttls: 1 ```
