# Kubeproxy
<img src="https://netdata.cloud/img/kubernetes.svg" width="150"/>
Plugin: go.d.plugin
Module: k8s_kubeproxy
<img src="https://img.shields.io/badge/maintained%20by-Netdata-%2300ab44" />
## Overview
This collector monitors Kubeproxy instances.
This collector is supported on all platforms.
This collector supports collecting metrics from multiple instances of this integration, including remote instances.
### Default Behavior
#### Auto-Detection
This integration doesn't support auto-detection.
#### Limits
The default configuration for this integration does not impose any limits on data collection.
#### Performance Impact
The default configuration for this integration is not expected to impose a significant performance impact on the system.
## Metrics
Metrics grouped by *scope*.
The scope defines the instance that the metric belongs to. An instance is uniquely identified by a set of labels.
### Per Kubeproxy instance
These metrics refer to the entire monitored application.
This scope has no labels.
Metrics:
| Metric | Dimensions | Unit |
|:------|:----------|:----|
| k8s_kubeproxy.kubeproxy_sync_proxy_rules | sync_proxy_rules | events/s |
| k8s_kubeproxy.kubeproxy_sync_proxy_rules_latency_microsecond | 0.001, 0.002, 0.004, 0.008, 0.016, 0.032, 0.064, 0.128, 0.256, 0.512, 1.024, 2.048, 4.096, 8.192, 16.384, +Inf | observes/s |
| k8s_kubeproxy.kubeproxy_sync_proxy_rules_latency | 0.001, 0.002, 0.004, 0.008, 0.016, 0.032, 0.064, 0.128, 0.256, 0.512, 1.024, 2.048, 4.096, 8.192, 16.384, +Inf | percentage |
| k8s_kubeproxy.rest_client_requests_by_code | a dimension per HTTP status code | requests/s |
| k8s_kubeproxy.rest_client_requests_by_method | a dimension per HTTP method | requests/s |
| k8s_kubeproxy.http_request_duration | 0.5, 0.9, 0.99 | microseconds |
## Alerts
There are no alerts configured by default for this integration.
## Setup
### Prerequisites
No action required.
### Configuration
#### File
The configuration file name for this integration is `go.d/k8s_kubeproxy.conf`.
You can edit the configuration file using the `edit-config` script from the
Netdata [config directory](/docs/netdata-agent/configuration/README.md#the-netdata-config-directory).
```bash
cd /etc/netdata 2>/dev/null || cd /opt/netdata/etc/netdata
sudo ./edit-config go.d/k8s_kubeproxy.conf
```
#### Options
The following options can be defined globally: update_every, autodetection_retry.
<details open><summary>Config options</summary>
| Name | Description | Default | Required |
|:----|:-----------|:-------|:--------:|
| update_every | Data collection frequency. | 1 | no |
| autodetection_retry | Recheck interval in seconds. Zero means no recheck will be scheduled. | 0 | no |
| url | Server URL. | http://127.0.0.1:10249/metrics | yes |
| timeout | HTTP request timeout. | 1 | no |
| username | Username for basic HTTP authentication. | | no |
| password | Password for basic HTTP authentication. | | no |
| proxy_url | Proxy URL. | | no |
| proxy_username | Username for proxy basic HTTP authentication. | | no |
| proxy_password | Password for proxy basic HTTP authentication. | | no |
| method | HTTP request method. | GET | no |
| body | HTTP request body. | | no |
| headers | HTTP request headers. | | no |
| not_follow_redirects | Redirect handling policy. Controls whether the client follows redirects. | no | no |
| tls_skip_verify | Server certificate chain and hostname validation policy. Controls whether the client performs this check. | no | no |
| tls_ca | Certification authority that the client uses when verifying the server's certificates. | | no |
| tls_cert | Client TLS certificate. | | no |
| tls_key | Client TLS key. | | no |

#### Examples
##### Basic
A basic example configuration.
```yaml
jobs:
- name: local
url: http://127.0.0.1:10249/metrics
```
##### HTTPS with self-signed certificate
Do not validate server certificate chain and hostname.

## Troubleshooting
### Debug Mode
**Important**: Debug mode is not supported for data collection jobs created via the UI using the Dyncfg feature.
To troubleshoot issues with the `k8s_kubeproxy` 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]`.
```bash
cd /usr/libexec/netdata/plugins.d/
```
- Switch to the `netdata` user.
```bash
sudo -u netdata -s
```
- Run the `go.d.plugin` to debug the collector:
```bash
./go.d.plugin -d -m k8s_kubeproxy
```
### Getting Logs
If you're encountering problems with the `k8s_kubeproxy` collector, follow these steps to retrieve logs and identify potential issues:
- **Run the command** specific to your system (systemd, non-systemd, or Docker container).
- **Examine the output** for any warnings or error messages that might indicate issues. These messages should provide clues about the root cause of the problem.
#### System with systemd
Use the following command to view logs generated since the last Netdata service restart:
```bash
journalctl _SYSTEMD_INVOCATION_ID="$(systemctl show --value --property=InvocationID netdata)" --namespace=netdata --grep k8s_kubeproxy
```
#### System without systemd
Locate the collector log file, typically at `/var/log/netdata/collector.log`, and use `grep` to filter for collector's name:
```bash
grep k8s_kubeproxy /var/log/netdata/collector.log
```
**Note**: This method shows logs from all restarts. Focus on the **latest entries** for troubleshooting current issues.
#### Docker Container
If your Netdata runs in a Docker container named "netdata" (replace if different), use this command:
```bash
docker logs netdata 2>&1 | grep k8s_kubeproxy
```
