Additionally, we do currently have logs available at the node level in our UI which jumps into the logs UI which has a list of all logs for that node. Can you confirm that's not what you're looking for?
Hi @Guest ! Nice to meet you. I'm Jayanth, the PM for Kubernetes at Instana.
Thanks for the additional context. What would be useful for us to know is:
How do you currently view these logs today? What kubectl commands do you run or do you use another tool? Can you show us a screenshot?
Can you provide an example log entry which you would generally use to troubleshoot an issue? Having an example will help us ensure we're collecting the right data from kubelet.
Hi Team,
We had a meeting with your team on this & we need it so that it will be helpful in below ways.
Troubleshooting: Kubelet logs help diagnose issues with nodes and the containers running on them. For instance, if a pod isn't starting or behaving as expected, kubelet logs can provide detailed insights into why the container failed or why the node might be misbehaving.
Monitoring Node Health: They offer visibility into the health and performance of nodes. You can monitor logs to check for signs of resource constraints, such as memory or CPU pressure, and to understand if the node is encountering problems.
Debugging: When dealing with node-specific issues, kubelet logs can show errors or warnings related to the node's interaction with the Kubernetes control plane. This is essential for debugging problems with node communication or configuration.
Understanding Node Operations: Kubelet logs include information about how the kubelet is managing pods, including starting, stopping, and managing the containers. This helps in understanding the lifecycle of pods and containers on the node.
Auditing and Compliance: For auditing purposes, kubelet logs provide a record of operations and interactions on the node. This can be important for security and compliance audits, ensuring that the node is operating as intended and adhering to policies.
Performance Tuning: By analyzing logs, you can identify performance bottlenecks or inefficiencies. This can guide tuning and optimization efforts to improve overall cluster performance.
In summary, kubelet logs are a vital resource for maintaining the health, performance, and reliability of Kubernetes nodes and clusters. They provide essential information for both reactive troubleshooting and proactive maintenance.
