pods qui sont trop gourmands en mémoire

utilisation anormale au niveau des pods (disque dur qui sature, etc)

pods that are too memory hungry

abnormal use of pods (hard drive saturating, etc.)

1. pods that are too memory hungry

Following this tutorial:

https://www.replex.io/blog/kubernetes-in-production-the-ultimate-guide-to-monitoring-resource-metrics

sum (container_memory_usage_bytes{pod="<pod name>"}) by (node)

Filesystem metrics: https://www.robustperception.io/filesystem-metrics-from-the-node-exporter

2. Abnormal use pods (hard drive saturating)

Following this (https://devconnected.com/monitoring-disk-i-o-on-linux-with-the-node-exporter/) We can have these:

• Unusual read rate / write rate
• Disk I/O - Out of Disk Space
• Unusual disk read latency

CPU per pod:

Following this to have CPU usage per pod: https://stackoverflow.com/questions/40327062/how-to-calculate-containers-cpu-usage-in-kubernetes-with-prometheus-as-monitori

• sum (rate (container_cpu_usage_seconds_total{image!=""}[1m])) by (pod_name)
