84. K8s Monitoring– What?
• Hosts (where K8s components run)
• K8s itself
• Services, e.g. Deployments, *Sets, Jobs
• Pods and Containers
• Key metrics
Not only infrastructure but also workloads
85. K8s Monitoring – Complexity
• Loads of resource types
• Multiple components and layers
• Different failure points
• Understanding of the entire stack
Via hosts, services and check plugins?
87. K8s Monitoring – Probes
Liveness probes periodically check container liveness and
restart containers that fail it.
Readiness probes indicate container readiness and remove
failing ones from their service endpoints.
Startup probes defer the execution of liveness and readiness
probes and restarts containers that fail it.
88. K8s Monitoring – Approaches
• Poll K8s APIs
• Agent per node via DaemonSet
• Agent per pod (sidecar container)
• Events
• Metrics
• Logs
• APM
89. Possible K8s Metric Sources
• Node metrics from Prometheus node exporter
• Container metrics from cAdvisor (or metrics-server)
• K8s metrics
• API server
• etcd
• scheduler
• controller manager
• kube-state-metrics
