Section 4 – validations

As we now expect the results to be stored in the trace_result variable, we need to ensure each of the output responses is validated for each host.

Using with_items, we iterate over the results of the trace_result variable. As the earlier execution happened over multiple hosts, the output stored in trace_result is in list format. To iterate each item in the variable, we refer trace_result.results instead of only the variable:

  # - name: Debug registered variables    # debug: var=trace_result    - name: Check ping failure      fail: msg="Ping not responding {{ item.stdout_lines }}"      when: "'100 percent' not in item.stdout[0]"       with_items: "{{ trace_result.results }}"     #when: "'100 percent' not in "{{ trace_result }}""

The fail and ...
