New Relic Kubernetes logging

Welcome to the New Relic Fluent Bit output plugin for Kubernetes! There are only a few quick steps to getting this working in your cluster.

Usage

Deploying as Helm chart (Recommended)

• Clone this repo
• Deploy the chart using your New Relic license key: helm install --set licenseKey=(your-license-key),clusterName=(your-cluster-name) ./helm/newrelic-logging
• If you are in the EU, make sure that the license key you are using is an EU key. You will not need to specify the EU logging endpoint -- it will be inferred from the license key
• Check New Relic for your logs

Applying k8s manifests manually

• Clone this repo
• Configure the plugin. In new-relic-fluent-plugin.yml:
  • Specify your New Relic license key in the value for LICENSE_KEY
  • Specify your Kubernetes cluster name in the value for CLUSTER_NAME
  • If you are in the EU:
    • Override the ENDPOINT environment variable to https://log-api.eu.newrelic.com/log/v1
    • Make sure that the license key you are using is an EU key
• From this directory, run kubectl apply -f . on your cluster
• Check New Relic for your logs

Find and use your data

For how to find and query your data in New Relic, see Find log data.

For general querying information, see:

• Query New Relic data
• Intro to NRQL

Configuration notes

We default to tailing /var/log/containers/*.log. If you want to change what's tailed, just update the PATH value in new-relic-fluent-plugin.yml.

Parsing

We currently support parsing json and docker logs. If you want more parsing, feel free to add more parsers in fluent-conf.yml.

Here are some parsers for your parsing pleasure.
