Yesterday I discussed a Linode Prometheus Exporter and tantalized use of Prometheus AlertManager. Success: Configure The process is straightforward although I found the Prometheus (config) documentation slightly unwieldy to navigate :-( The overall process is documented. Here are the steps I took: Configure Prometheus Configure AlertManager Revise Docker Compose Configure Prometheus Added the following to prometheus.yml: rule_files: - "/etc/alertmanager/rules/linode.yml" alerting: alertmanagers: - scheme: http static_configs: - targets: - "alertmanager:9093" Rules must be defined in separate rules files.

I enjoy using Prometheus and have toyed around with it for some time particularly in combination with Kubernetes. I signed up with Linode [referral] compelled by the addition of a managed Kubernetes service called Linode Kubernetes Engine (LKE). I have an anxiety that I’ll inadvertently leave resources running (unused) on a cloud platform. Instead of refreshing the relevant billing page, it struck me that Prometheus may (not yet proven) help.
