Konfigurasi metrik Prometheus default di Azure Monitor

Artikel ini mencantumkan target, dasbor, dan aturan perekaman default saat Anda mengonfigurasi metrik Prometheus untuk diekstraksi dari kluster Azure Kubernetes Service (AKS) untuk kluster AKS apa pun.

Profil penyerapan minimal

Minimal ingestion profile adalah pengaturan yang membantu mengurangi volume metrik penyerapan, karena hanya metrik yang digunakan oleh dasbor default, aturan perekaman default & pemberitahuan default yang dikumpulkan. Untuk koleksi berbasis addon, Minimal ingestion profile pengaturan diaktifkan secara default. Anda dapat mengubah koleksi untuk memungkinkan pengumpulan lebih banyak metrik, seperti yang ditentukan di bawah ini.

Frekuensi scrape

Frekuensi scrape default untuk semua target dan goresan default adalah 30 detik.

Target diekstraksi secara default

Target berikut diaktifkan/AKTIF secara default - yang berarti Anda tidak perlu menyediakan konfigurasi pekerjaan scrape apa pun untuk mengikis target ini, karena addon metrik akan mengikis target ini secara otomatis secara default

• nodeexporterAku akan menemuinya.job=node
• kubeletAku akan menemuinya.job=kubelet

Metrik yang dikumpulkan dari target default

Metrik berikut dikumpulkan secara default dari setiap target default. Semua metrik lainnya dihilangkan melalui aturan pelabelan ulang.

Target default diekstraksi untuk Windows

Target Windows berikut dikonfigurasi untuk mengikis, tetapi pengikisan tidak diaktifkan (dinonaktifkan/NONAKTIF) secara default - yang berarti Anda tidak perlu menyediakan konfigurasi pekerjaan scrape apa pun untuk mengikis target ini tetapi dinonaktifkan/NONAKTIF secara default dan Anda perlu mengaktifkan/mengaktifkan pengikisan untuk target ini menggunakan ama-metrics-settings-configmap di bawah default-scrape-settings-enabled bagian

Dua pekerjaan default dapat dijalankan untuk Windows yang mengikis metrik yang diperlukan untuk dasbor khusus untuk Windows.

• windows-exporterAku akan menemuinya.job=windows-exporter
• kube-proxy-windowsAku akan menemuinya.job=kube-proxy-windows

Catatan

Ini memerlukan penerapan atau pembaruan ama-metrics-settings-configmap configmap dan menginstal windows-exporter pada semua simpul Windows. Untuk informasi selengkapnya, lihat dokumen pengaktifan.

Dashboard

Dasbor default berikut secara otomatis disediakan dan dikonfigurasi oleh layanan terkelola Azure Monitor untuk Prometheus saat Anda menautkan ruang kerja Azure Monitor Anda ke instans Azure Managed Grafana. Kode sumber untuk dasbor ini dapat ditemukan di repositori GitHub ini. Dasbor di bawah ini akan disediakan dalam instans Azure Grafana yang ditentukan di bawah Managed Prometheus folder di Grafana. Ini adalah dasbor komunitas sumber terbuka standar untuk memantau kluster Kubernetes dengan Prometheus dan Grafana.
