Logging dan Logging Audit (LOG dan AL)

Log audit Logging dan Audit Logging (LOG dan AL) di Google Distributed Cloud (GDC) dengan air gap memungkinkan Anda melacak operasi akses data dan administratif untuk pipeline logging dan pemantauan dalam workload organisasi. Log audit Kubernetes dan logger audit kemampuan observasi mencatat identitas pengguna atau layanan, resource target, dan kolom payload JSON untuk resource kustom LoggingTarget, LoggingRule, dan SIEMOrgForwarder serta untuk kueri Loki dan Prometheus.

Sumber log audit
Operasi yang diaudit

Menjalankan kueri LogQL atau mengekspor log menggunakan antarmuka pengguna instance pemantauan

Sumber log audit

Server proxy
Jenis log

Bidang data
Kolom dalam entri log yang berisi informasi audit
Metadata audit Nama kolom audit Nilai
Identitas pengguna atau layanan user

Misalnya,

"user": {
  "issuer": "https://ais-core.org-1.zone1.google.gdch.test",
  "identity": "fop-infrastructure-operator@example.com"
  }

Target

(Kolom dan nilai yang memanggil API)

 resource

Misalnya,

"resource": "/infra-obs/grafana/api/ds/query"

Tindakan

(Kolom yang berisi operasi yang dilakukan)

 action

Nilai yang memungkinkan:

  • "action": "QUERY"
  • "action": "CREATE"
  • "action": "READ"
  • "action": "UPDATE"
  • "action": "DELETE"
  • "action": "CREATE/UPDATE"
Stempel waktu peristiwa time

Misalnya,

"time": "2022-12-02T21:37:03.657277582Z"

Sumber tindakan
  • sourceIPs
  • _gdch_service_name

Misalnya,

"sourceIPs": [
  [
  "10.253.165.26",
  "127.0.0.6"
],
"_gdch_service_name": "grafana"
Hasil response

Misalnya,

"response": "Successful: 200 OK"
Kolom lain description Nilai description berisi kueri lengkap. Untuk mengetahui informasi selengkapnya, lihat Contoh log.
