# Référence des journaux de performances Container Insights
Cette section inclut des informations de référence sur la façon dont Container Insights utilise les évènements de journaux de performances pour collecter les métriques. Lorsque vous déployez Container Insights, il crée automatiquement un groupe de journaux pour les événements du journal des performances. Il n'est pas nécessaire de créer ce groupe de journaux vous-même.

# Évènements de journaux de performances de Container Insights pour Amazon ECS
Voici des exemples d'évènements de journaux de performance que Container Insights collecte depuis Amazon ECS.
Ces journaux se trouvent dans CloudWatch Logs, dans un groupe de journaux nommé`/aws/ecs/containerinsights/CLUSTER_NAME/performance`. Au sein de ce groupe de journaux, chaque instance de conteneur aura un flux de journaux nommé `AgentTelemetry-CONTAINER_INSTANCE_ID`.
Vous pouvez interroger ces journaux à l'aide de requêtes, par exemple `{ $.Type = "Container" }` pour afficher tous les événements des journaux de conteneurs.
**Type : Conteneur**

# Champs pertinents dans les évènements de journaux de performance pour Amazon EKS et Kubernetes
Pour Amazon EKS et Kubernetes, l' CloudWatch agent conteneurisé émet des données sous forme d'événements du journal des performances. Cela permet d' CloudWatch ingérer et de stocker des données à haute cardinalité. CloudWatch utilise les données contenues dans les événements du journal des performances pour créer CloudWatch des métriques agrégées au niveau du cluster, du nœud et du pod sans perdre de détails granulaires.
Le tableau suivant répertorie les champs de ces événements du journal de performances qui sont pertinents pour la collecte de données de métriques Container Insights. Vous pouvez utiliser CloudWatch Logs Insights pour rechercher l'un de ces champs afin de collecter des données ou d'étudier des problèmes. Pour plus d'informations, voir [Analyser les données des CloudWatch journaux avec Logs Insights](https://docs.aws.amazon.com/AmazonCloudWatch/latest/logs/AnalyzingLogData.html).
| Type | Champ de journal | Source | Formule ou notes |
| --- | --- | --- | --- |
| pod | `pod_cpu_utilization` | Calculé | Formule : `pod_cpu_usage_total / node_cpu_limit` |
| pod | `pod_cpu_usage_total` `pod_cpu_usage_total` est signalé en Millicores. | cadvisor | |
| pod | `pod_cpu_limit` | Calculé | Formule : `sum(container_cpu_limit)` `sum(container_cpu_limit)` inclut des pods déjà terminés. Si l'un des conteneurs dans le pod n'a pas de limite d'UC définie, ce champ n'apparaît pas dans l'événement de journal. Inclut les [conteneurs init](https://kubernetes.io/docs/concepts/workloads/pods/init-containers/#resources). |
| pod | `pod_cpu_request` | Calculé | Formule : `sum(container_cpu_request)` L'élément `container_cpu_request` n'est pas forcément défini. Seuls ceux définis sont inclus dans la somme. |

| pod | `pod_network_tx_bytes` | Calculé | Formule : `sum(pod_interface_network_tx_bytes)` Ces données sont disponibles pour toutes les interfaces réseau (par pod). L'agent CloudWatch calcule le total et ajoute des règles d'extraction de métrique. |
| pod | `pod_network_rx_bytes` | Calculé | Formule : `sum(pod_interface_network_rx_bytes)` |
| pod | `pod_network_total_bytes` | Calculé | Formule : `pod_network_rx_bytes + pod_network_tx_bytes` |

node_cpu_limit = 4
node_cpu_usage_total = 3
Pod1
pod_cpu_usage_total = 2

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

Le tableau suivant montre la façon dont les métriques d'UC du pod sont calculées à l'aide de ces données.
| Métrique | Formule | Pod1 | Pod2 | Pod3 |
| --- | --- | --- | --- | --- |
| `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)` | Non applicable (N/A), car la limite d'UC pour `Container2` n'est pas définie | 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 % |
Le tableau suivant montre la façon dont les métriques d'UC du nœud sont calculées à l'aide de ces données.
