# Referensi log performa Wawasan Kontainer
Bagian ini mencakup informasi referensi tentang bagaimana Wawasan Kontainer menggunakan peristiwa log peforma untuk mengumpulkan metrik. Saat Anda menerapkan Wawasan Kontainer, ia akan secara otomatis membuat suatu grup log untuk peristiwa log performa. Anda tidak harus membuat grup log ini sendiri.

# Peristiwa log performa Wawasan Kontainer untuk Amazon ECS
Berikut ini adalah contoh-contoh peristiwa log performa yang dikumpulkan oleh Wawasan Kontainer dari Amazon ECS.
Log ini ada di CloudWatch Log, dalam grup log bernama`/aws/ecs/containerinsights/CLUSTER_NAME/performance`. Dalam grup log itu, masing-masing instans kontainer akan memiliki sebuah log stream bernama `AgentTelemetry-CONTAINER_INSTANCE_ID`.
Anda dapat menjalankan kueri atas log ini dengan menggunakan kueri seperti `{ $.Type = "Container" }` untuk menampilkan semua peristiwa log kontainer.
**Tipe: Kontainer**

# Bidang-bidang relevan dalam peristiwa log performa untuk Amazon EKS dan Kubernetes
Untuk Amazon EKS dan Kubernetes, CloudWatch agen containerized memancarkan data sebagai peristiwa log kinerja. Ini memungkinkan CloudWatch untuk menelan dan menyimpan data kardinalitas tinggi. CloudWatch menggunakan data dalam peristiwa log kinerja untuk membuat CloudWatch metrik agregat di level cluster, node, dan pod tanpa perlu kehilangan detail granular.
Tabel berikut mencantumkan bidang-bidang dalam peristiwa log performa yang relevan dengan pengumpulan data metrik Wawasan Kontainer. Anda dapat menggunakan Wawasan CloudWatch Log untuk menanyakan salah satu bidang ini guna mengumpulkan data atau menyelidiki masalah. Untuk informasi selengkapnya, lihat [Menganalisis Data Log Dengan Wawasan CloudWatch Log](https://docs.aws.amazon.com/AmazonCloudWatch/latest/logs/AnalyzingLogData.html).

## Contoh-contoh perhitungan metrik
Bagian ini mencakup contoh-contoh yang menunjukkan bagaimana beberapa nilai dalam tabel sebelumnya dikalkulasikan.
Bayangkan Anda memiliki sebuah klaster dalam status berikut.
```
Node1
node_cpu_limit = 4
node_cpu_usage_total = 3
Pod1
pod_cpu_usage_total = 2
Container1
container_cpu_limit = 1
container_cpu_request = 1
container_cpu_usage_total = 0.8
Container2
container_cpu_limit = null
container_cpu_request = null
container_cpu_usage_total = 1.2
Pod2
pod_cpu_usage_total = 0.4
Container3
container_cpu_limit = 1
container_cpu_request = 0.5
container_cpu_usage_total = 0.4
Node2
node_cpu_limit = 8
node_cpu_usage_total = 1.5
Pod3
pod_cpu_usage_total = 1
Container4
container_cpu_limit = 2
container_cpu_request = 2
container_cpu_usage_total = 1
```

| --- | --- | --- | --- | --- |
| `pod_cpu_utilization` | `pod_cpu_usage_total / node_cpu_limit` | 2 / 4 = 50% | 0,4 / 4 = 10% | 1 / 8 = 12.5% |
| `pod_cpu_utilization_over_pod_limit` | `pod_cpu_usage_total / sum(container_cpu_limit)` | Tidak berlaku karena batas CPU untuk `Container2` tidak ditentukan | 0,4 / 1 = 40% | 1 / 2 = 50% |
| `pod_cpu_reserved_capacity` | `sum(container_cpu_request) / node_cpu_limit` | (1 \$1 0) / 4 = 25% | 0,5 / 4 = 12.5% | 2 / 8 = 25% |
Tabel berikut menunjukkan bagaimana metrik-metrik CPU simpul dikalkulasikan dengan menggunakan data ini.
