# Referenz zu Container-Insights-Leistungsprotokollen
Dieser Abschnitt enthält Referenzinformationen darüber, wie Container Insights Peformance-Protokollereignisse verwendet, um Metriken zu erfassen. Wenn Sie Container Insights einsetzen, erstellt es automatisch eine Protokollgruppe für die Leistungsprotokoll-Ereignisse. Sie müssen diese Protokollgruppe nicht selbst erstellen.

# Performance-Protokollereignisse von Container Insights für Amazon ECS
Im Folgenden finden Sie Beispiele für die Performance-Protokollereignisse, die Container Insights von Amazon ECS sammelt.
Diese Protokolle befinden sich in der Protokollgruppe CloudWatch Logs mit dem Namen`/aws/ecs/containerinsights/CLUSTER_NAME/performance`. Innerhalb dieser Protokollgruppe hat jede Container-Instance einen Protokollstream mit dem Namen `AgentTelemetry-CONTAINER_INSTANCE_ID`.
Sie können diese Protokolle mithilfe von Abfragen abfragen, z. B. `{ $.Type = "Container" }`, um alle Container-Protokollereignisse anzuzeigen.

# Relevante Felder in Performance-Protokollereignissen für Amazon EKS und Kubernetes
Für Amazon EKS und Kubernetes gibt der containerisierte CloudWatch Agent Daten als Leistungsprotokollereignisse aus. Dies ermöglicht die Aufnahme und Speicherung von Daten CloudWatch mit hoher Kardinalität. CloudWatch verwendet die Daten in den Leistungsprotokollereignissen, um aggregierte CloudWatch Metriken auf Cluster-, Knoten- und Pod-Ebene zu erstellen, ohne dass detaillierte Details verloren gehen müssen.
In der folgenden Tabelle werden die Felder in diesen Performance-Protokollereignissen aufgelistet, die für die Sammlung von Container Insights-Metrikdaten relevant sind. Sie können CloudWatch Logs Insights verwenden, um jedes dieser Felder abzufragen, um Daten zu sammeln oder Probleme zu untersuchen. Weitere Informationen finden Sie unter [Analysieren von Protokolldaten mit CloudWatch Logs Insights](https://docs.aws.amazon.com/AmazonCloudWatch/latest/logs/AnalyzingLogData.html).
| Typ | Protokollfeld | Quelle | Formel oder Hinweise |
| --- | --- | --- | --- |
| Pod | `pod_cpu_utilization` | Berechnet | Formel: `pod_cpu_usage_total / node_cpu_limit` |
| Schote | `pod_cpu_usage_total` `pod_cpu_usage_total` wird in Millicore gemeldet. | cadvisor | |
| Schote | `pod_cpu_limit` | Berechnet | Formel: `sum(container_cpu_limit)` `sum(container_cpu_limit)` beinhaltet bereits abgeschlossene Pods. Dieses Feld erscheint nur im Protokollereignis, wenn für alle Container im Pod ein CPU-Limit definiert ist. Dies schließt [ Init-Container](https://kubernetes.io/docs/concepts/workloads/pods/init-containers/#resources) ein. |
| Schote | `pod_cpu_request` | Berechnet | Formel: `sum(container_cpu_request)` Es ist nicht garantiert, dass `container_cpu_request` eingestellt wird. Nur diejenigen, die eingestellt sind, sind in der Summe enthalten. |
| Schote | `pod_cpu_utilization_over_pod_limit` | Berechnet | Formel: `pod_cpu_usage_total / pod_cpu_limit` |
| Schote | `pod_cpu_reserved_capacity` | Berechnet | Formel: `pod_cpu_request / node_cpu_limit` |
| Schote | `pod_memory_utilization` | Berechnet | Formel: `pod_memory_working_set / node_memory_limit` Dies ist der Prozentsatz der Pod-Speichernutzung bezüglich der Knotenspeicherbegrenzung. |
| Schote | `pod_memory_working_set` | cadvisor | |

Dies schließt [ Init-Container](https://kubernetes.io/docs/concepts/workloads/pods/init-containers/#resources) ein. |
| Schote | `pod_memory_request` | Berechnet | Formel: `sum(container_memory_request)` Es ist nicht garantiert, dass `container_memory_request` eingestellt wird. Nur diejenigen, die eingestellt sind, sind in der Summe enthalten. |
| Schote | `pod_memory_utilization_over_pod_limit` | Berechnet | Formel: `pod_memory_working_set / pod_memory_limit` Dieses Feld erscheint nur im Protokollereignis, wenn für alle Container im Pod ein Arbeitsspeicherlimit definiert ist. Dies schließt [ Init-Container](https://kubernetes.io/docs/concepts/workloads/pods/init-containers/#resources) ein. |
| Schote | `pod_memory_reserved_capacity` | Berechnet | Formel: `pod_memory_request / node_memory_limit` |
| Schote | `pod_network_tx_bytes` | Berechnet | Formel: `sum(pod_interface_network_tx_bytes)` Diese Daten sind für alle Netzwerkschnittstellen pro Pod verfügbar. Der CloudWatch-Agent berechnet die Summe und fügt Metrik-Extraktionsregeln hinzu. |
| Schote | `pod_network_rx_bytes` | Berechnet | Formel: `sum(pod_interface_network_rx_bytes)` |
| Schote | `pod_network_total_bytes` | Berechnet | Formel: `pod_network_rx_bytes + pod_network_tx_bytes` |
| PodNet | `pod_interface_network_rx_bytes` | cadvisor | Diese Daten sind rx-Bytes des Netzwerks pro Sekunde einer Pod-Netzwerkschnittstelle. |
| PodNet | `pod_interface_network_tx_bytes` | cadvisor | Diese Daten sind tx-Bytes des Netzwerks pro Sekunde einer Pod-Netzwerkschnittstelle. |
| Behälter | `container_cpu_usage_total` | cadvisor | |

| Behälter | `container_memory_working_set` | cadvisor | |
| Behälter | `container_memory_limit` | Pod | Es wird nicht garantiert, dass es festgelegt wird. Es wird nicht ausgegeben, wenn es nicht festgelegt ist. |
| Behälter | `container_memory_request` | Pod | Es wird nicht garantiert, dass es festgelegt wird. Es wird nicht ausgegeben, wenn es nicht festgelegt ist. |
| Knoten | `node_cpu_utilization` | Berechnet | Formel: `node_cpu_usage_total / node_cpu_limit` |
| Knoten | `node_cpu_usage_total` | cadvisor | |
| Knoten | `node_cpu_limit` | /proc | |
| Knoten | `node_cpu_request` | Berechnet | Formel: `sum(pod_cpu_request)` `node_cpu_request` schließt bei Cronjobs auch Anforderungen von abgeschlossenen Pods ein. Dies kann zu einem hohen Wert für `node_cpu_reserved_capacity` führen. |
| Knoten | `node_cpu_reserved_capacity` | Berechnet | Formel: `node_cpu_request / node_cpu_limit` |

## Beispiele für Metrikberechnungen
Dieser Abschnitt enthält Beispiele zur Veranschaulichung, wie einige der Werte in der vorangegangenen Tabelle berechnet werden.
Angenommen, Sie besitzen einen Cluster im folgenden Zustand.
```
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
```
Die folgende Tabelle zeigt, wie Pod-CPU-Metriken anhand dieser Daten berechnet werden.
| Metrik | Formel | 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)` | Nicht zutreffend, da kein CPU-Limit für `Container2` nicht definiert ist | 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 % |
Die folgende Tabelle zeigt, wie Knoten-CPU-Metriken anhand dieser Daten berechnet werden.
| Metrik | Formel | Knoten1 | Knoten2 |
| --- | --- | --- | --- |
| `node_cpu_utilization` | `node_cpu_usage_total / node_cpu_limit` | 3/4 = 75 % | 1,5/8 = 18,75 % |
| `node_cpu_reserved_capacity` | `sum(pod_cpu_request) / node_cpu_limit` | 1,5/4 = 37,5 % | 2/8 = 25 % |
