How To Enable Verbose Logging for Kubelet on a Node?
Problem
- Procedure to increase the log verbosity of pf9-kubelet service to a higher level.
Environment
- Platform9 Managed Kubernetes - All versions
Procedure
- Check the current verbosity level of process
pf9-kubelet.
# ps -ef | grep kubeletroot 26642 1 3 18:15 ? 00:00:04 /opt/pf9/pf9-kube/bin/kubelet --kubeconfig=/etc/pf9/kube.d/kubeconfigs/kubelet.yaml --enable-server --network-plugin=cni --cni-conf-dir=/etc/cni/net.d --cni-bin-dir=/opt/cni/bin --log-dir=/var/log/pf9/kubelet/ --logtostderr=false --config=/var/opt/pf9/kube/kubelet-config/bootstrap-config.yaml --register-schedulable=false --pod-infra-container-image=localhost:5100/pause:3.2 --dynamic-config-dir=/var/opt/pf9/kube/kubelet-config/dynamic-config --hostname-override=10.69.74.160 --v=2- Edit systemd service file for pf9-kubelet i.e. /run/systemd/system/pf9-kubelet.service to increase logging verbosity to
--v=8.

[root@worker1 ~]# vi /run/systemd/system/pf9-kubelet.service[root@worker1 ~]# cat /run/systemd/system/pf9-kubelet.service | grep "v=" --kubeconfig=/etc/pf9/kube.d/kubeconfigs/kubelet.yaml --enable-server --network-plugin=cni --cni-conf-dir=/etc/cni/net.d --cni-bin-dir=/opt/cni/bin --log-dir=/var/log/pf9/kubelet/ --logtostderr=false --config=/var/opt/pf9/kube/kubelet-config/bootstrap-config.yaml --register-schedulable=false --pod-infra-container-image=localhost:5100/pause:3.2 --dynamic-config-dir=/var/opt/pf9/kube/kubelet-config/dynamic-config --hostname-override=10.128.146.217 --v=8- Reload the systemd daemon and restart the pf9-kubelet service on the node post above changes.
[root@worker1 ~]# systemctl daemon-reload[root@worker1 ~]# systemctl restart pf9-kubelet- Once again check and verify the verbosity level of process
pf9-kubelet.
