Honeycomb Verification Skill

Purpose

Query Honeycomb to find the traces that were created by a recent test.

When to Use

This skill is automatically activated when:

• User asks to "show me a trace in Honeycomb"
• Completing an implementation step that requires observability verification

Verification Output

Report query results as: Queried [VIZ] where [FILTERS] by [GROUP_BY] over [TIME_RANGE] Results: [link to Honeycomb query]

Query Patterns

• Time Range: 1200 seconds (20 minutes) - adjustable based on when the test started

Pattern 1: Get a particular trace

What service are you testing? This determines the dataset. Do you know the name of the span you expect to see?

Query for:
- dataset: [dataset]
- filter: name = [expected span name]
- time_range: [calculated time range]
- calculation: COUNT
- include_samples: true

Now take the most recent sample, and use get_trace to get the full trace. Output:

Queried [CALCULATION] where [FILTERS] over [TIME_RANGE] Found [count] results Results: [link to the query]

Most recent trace: [link to the trace] Root span: [root span name] Total spans: [count of spans] Services: [list of services]

Pattern 2: Find all traces since the test started

Query for:
- all datasets
- filter: trace.parent_id does-not-exist
- time_range: [calculated time range]
- calculation: COUNT
- breakdowns: name
- include_samples: true

Output: Queried [CALCULATION] where [FILTERS] by [BREAKDOWNS] over [TIME_RANGE] Found [count] results Results: [link to the query]

For each sample, print:

• Trace ID
• Span name
• anything else it gives you Construct a link to the trace in Honeycomb, according to: https://ui.honeycomb.io/modernity/environments/personal-agent/trace?trace_id=[<traceId>] &trace_start_ts=[test_start_time] &trace_end_ts=[((date +%s))]

Pattern 3: Find the most recent trace, precisely

Query for:
  calculated_fields: event_time=EVENT_TIMESTAMP()
  calculation: COUNT
  breakdowns: event_time, trace.trace_id
  order: event_time DESC
  limit: 1
  include_samples: false

Print the summary of the trace, as in Pattern 1.

Take the output trace_id and use get_trace to get the full trace.

Pattern 4: When you don't see any traces, try: Get the time range right

Before running a test that will generate a trace, print the current time.

start_time=$(date +%s)

Then run the test to create the trace.

Then calculate the correct time range:

echo $(( $(date +%s) - $start_time + 20))

Include that in the query you're using to find traces.
