  • Uptime monitoring (~1000 urls)

    You could use prometheus as a monitoring tool, blackbox_exporter to "export" the urls to prometheus, alertmanager for notifications, and grafana for nice gui dashboards (and maybe also notifications).

    vmalert: executes a list of the given alerting or recording rules against configured data sources. For sending alerting notifications vmalert relies on configured Alertmanager. Recording rules results are persisted via remote write protocol. vmalert is heavily inspired by Prometheus implementation and aims to be compatible with its syntax
  • Can Prometheus act similar to OPC A&E server?

    Yes, I believe you can do all of what you're looking for without a UI. The alertmanager api has the ability to register receivers as well as to poll for alerts, silence them, etc: https://github.com/prometheus/alertmanager/blob/main/api/v2/openapi.yaml

    At a high level, I use various Prometheus exporters, including node-exporter and some simple custom exporters, which can then be consumed by Grafana for dashboards, Alert Manager for sending PushOver notifications, and my own web apps for displaying custom metrics. Hope that helps :)

    In any such scenarios, a tool like Prometheus can act as the time series database to collect all the metrics for you along with something like OpenTelemetry to expose metrics from the application and the various tools using inbuilt exporters, Alertmanager to send notifications and alerts to multiple channels, Grafana as the dashboard to visualize everything at one place and so on giving users a complete visibility on the infrastructure as a whole.
