لازمه اینجا بگم که گرفانا اخیرا ابزاری به نام Grafana Alloy رو معرفی کرده که قراره جایگزین بشه و ابزار اصلی کالکت کردن دیتای تلهمتری بشه.
گرافانا الوی ابزاری هست که برای OTel و Prometheus و Pyroscope و Loki و کلی ابزار متریک و لاگ و تریس و پروفایل دیگه، پایپ لاین های native ارائه میده. با استفاده از پایپ لاین های Alloy میتونید رول های آلرت روی لوکی و میمیر رو کانفیگ کنید و با پرومتئوس ایجنت و Promtail هم کاملا سازگار هست و میتونید اون رو روی زیرساخت های مختلف on-premise و ابری استفاده کنید.
این ابزار تنها برای سیگنال های Observability مثل متریک و لاگ و تریس نیست و کلی قابلیت دیگه هم داره که کمک میکنه تا سریع تر دیتامون رو توی محیط های پیچیده پیدا کنیم و اون رو پردازش کنیم. در ادامه لیستی از این قابلیت هارو براتون میارم:
Custom components
GitOps compatibility
Clustering support
Security
Debugging utilities

End-to-End Watchdog Alerts
Even if you build the most reliable internal meta-monitoring infrastructure, something can still go wrong: the meta-monitoring setup might have a systematic error that causes it to break, the Alertmanager through which notifications are supposed to get delivered to you might be down, or your entire organization's network might be disconnected from the internet!
To help you catch these kinds of situations as a last resort, it's a good idea to set up a watchdog alert (also sometimes called a "dead man's switch", sentinel alert, beacon alert, or heartbeat alert) that helps you continuously test your entire alerting pipeline from beginning to end.
You can achieve this by:
Configuring an alerting rule that is always firing, e.g. using the PromQL expression vector(1), or simply 1 (the numeric value doesn't matter) to always produce a single output time series.
Configuring Alertmanager to route the resulting alert notification to an external service with a repeat interval of a only a few (x) minutes.
Configuring the external service to expect an incoming alert notification every x minutes (plus some slack time) or to send you an alert notification otherwise.
