Description

A springboot app that uses distributed logging to trace api call. This will simulate a call to a remote service by chaining a single call through 2 services. Uses prometheus to graph response times.

STEP 1

Once the project is done building, make some api calls http://localhost:81.

STEP 2

• goto http://localhost
• click on "Find a trace"
  • search by "serviceName"

To see a graph of response times:

• Nav to http://localhost:82
• Classic UI
  • Click Graph tab
    • Search: 'scrape_series_added' or 'scrape_duration_second' or 'http_request_duration_ms_bucket'
    • Duration 1m

For health check:

• Nav to http://localhost:82
• Targetes

To see Prometheus dashboards:

• Nav to http://localhost:83
• Login with admin/admin
• configuration -> datasources
  • Select Prometheus
    • dashboards
      • import and click label

To see Zipkin dashboards:

• Nav to http://localhost:83
• Login with admin/admin
