Kubelet monitoring with Netdata

Kubelet is an agent that runs on each node in the cluster. It makes sure that containers are running in a pod.

This module will monitor one or more kubelet instances, depending on your configuration.

Charts

It produces the following charts:

API Server Audit Requests in requests/s
API Server Failed Data Encryption Key(DEK) Generation Operations in events/s
API Server Latencies Of Data Encryption Key(DEK) Generation Operations in observes/s
API Server Latencies Of Data Encryption Key(DEK) Generation Operations Percentage in %
API Server Storage Envelope Transformation Cache Missesinevents/s`
Number Of Containers Currently Running in containers
Number Of Pods Currently Running in pods
Bytes Used By The Pod Logs On The Filesystem in bytes
Runtime Operations By Type in operations/s
Docker Operations By Type in operations/s
Docker Operations Errors By Type in operations/s
Node Configuration-Related Error in bool
PLEG Relisting Interval Summary in microseconds
PLEG Relisting Latency Summary in microseconds
Token Requests To The Alternate Token Source in requests/s
REST Client HTTP Requests By Status Code in requests/s
REST Client HTTP Requests By Method in requests/s

Per every plugin:

Volume Manager State Of The World in state

Configuration

Edit the go.d/k8s_kubelet.conf configuration file using edit-config from the Netdata config directory, which is typically at /etc/netdata.

cd /etc/netdata # Replace this path with your Netdata config directory
sudo ./edit-config go.d/k8s_kubelet.conf

Needs only url to kubelet metric-address. Here is an example for 2 instances:

jobs:
  - name: local
    url: http://127.0.0.1:10255/metrics

  - name: remote
    url: http://203.0.113.10:10255/metrics

For all available options please see module configuration file.

Troubleshooting

To troubleshoot issues with the k8s_kubelet collector, run the go.d.plugin with the debug option enabled. The output should give you clues as to why the collector isn't working.

Navigate to the plugins.d directory, usually at /usr/libexec/netdata/plugins.d/. If that's not the case on your system, open netdata.conf and look for the plugins setting under [directories].
```
cd /usr/libexec/netdata/plugins.d/
```
Switch to the netdata user.
```
sudo -u netdata -s
```
Run the go.d.plugin to debug the collector:
```
./go.d.plugin -d -m k8s_kubelet
```
