Kube-proxy collector
Kube-proxy
is a network proxy that runs on each
node in your cluster, implementing part of the Kubernetes Service.
This module will monitor one or more kube-proxy
instances, depending on your configuration.
Metrics
All metrics have "k8s_kubeproxy." prefix.
Metric | Scope | Dimensions | Units |
---|---|---|---|
kubeproxy_sync_proxy_rules | global | sync_proxy_rules | events/s |
kubeproxy_sync_proxy_rules_latency_microsecond | global | 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 |
kubeproxy_sync_proxy_rules_latency | global | 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 |
rest_client_requests_by_code | global | a dimension per HTTP status code | requests/s |
rest_client_requests_by_method | global | a dimension per HTTP method | requests/s |
http_request_duration | global | 0.5, 0.9, 0.99 | microseconds |
Configuration
Edit the go.d/k8s_kubeproxy.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_kubeproxy.conf
Needs only url
to kube-proxy
metric-address. Here is an example for several instances:
jobs:
- name: local
url: http://127.0.0.1:10249/metrics
- name: remote
url: http://203.0.113.1:10249/metrics
For all available options please see module configuration file.
Troubleshooting
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, opennetdata.conf
and look for theplugins
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_kubeproxy
