Add Middleware Prometheus Integration as a sidecar container

We are currently updating this feature. If you have any issues configuring this integration, please contast us at support[at]middleware.io

To scrape the prometheus endpoint via Middleware Agent, You will have to add this sidecar container in your pod:

- name: middleware-prometheus-agent
  image: ghcr.io/middleware-labs/mw-kube-agent:prometheus-integration
  imagePullPolicy: Always
  env:
  - name: MW_TARGET
    value: https://xxxxx.middleware.io:443 # Middleware Target URL
  - name: MW_API_KEY
    value: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx # Middleware API Key
  - name: PROMETHEUS_SCRAPE_CONFIG
    value: job1@0.0.0.0:8889,job2@0.0.0.0:8890

​
Understanding Environment Variables

MW_TARGET : Specifies the target URL for the Middleware service. This URL defines the endpoint where your application should interact with the middleware.

Example Value : https://xxxxx.middleware.io:443

MW_API_KEY : Provides the API key required for authenticating with the Middleware service. Ensure the key is kept confidential and only shared with authorized users or services.

Example Value : xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

PROMETHEUS_SCRAPE_CONFIG : Configures Prometheus scraping targets. This variable should be set in the format ‘job@address:port’, where ‘job’ represents the scraping job name, ‘address’ is the IP address or hostname, and ‘port’ is the port to scrape metrics from.

Example Value : job1@0.0.0.0:8889,job2@0.0.0.0:8890
