Jaeger

Introduction

Jaeger is a software tool used to monitor and troubleshoot issues in microservices architectures, where multiple interconnected services work together to complete a task. It visualizes the flow of requests through various microservices, helping developers trace the path of requests and isolate problems when they arise.

Kubernetes 2.0 ConfigMap

Users should update or append the existing ConfigMap named opsramp-workload-metric-user-config by adding application-specific fields. These fields may include authentication credentials, collection frequency, and other relevant configurations.

apiVersion: v1
kind: ConfigMap
metadata:
  name: opsramp-workload-metric-user-config
  namespace: opsramp-agent
data:
  workloads: |
    jaeger:

      port: 14269
      scheme: "http"

            operator: ==
