Description

Calls remote services and benchmarks the response. Uses prometheus to graph response times and grafana for tracing.

STEP 1

Once the project is done building, make some api calls http://localhost:83/api/v1/names/random.

STEP 2

• goto http://localhost
• click on "Explore"
  • at the top change datasource to "Jaeger"
  • under "Trace" pick a service
    • pick "GET"
      • pick a single trace

To see a graph of response times:

• Nav to http://localhost:81
• 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:81
• Targetes

To see a coverage of response times:

• Nav to http://localhost:82
• Look on left-hand side find services.
