Examples
Adding custom attributes to background task
An example of adding custom attributes to a background task:
@newrelic.agent.background_task()def send_request(): response = requests.get("http://example.com") newrelic.agent.add_custom_attributes( [("url_path_status_code", response.status_code)] )Using custom attributes to troubleshoot
You can also use custom attributes to troubleshoot performance issues. For example, you might see occasional slow response times from a pool of memcache instances, but you don't know what instance is causing the problem. You might add an attribute to the transaction indicating the server, like so:
# Set server_ip to be the current server processing the transactionnewrelic.agent.add_custom_attributes([ ("memcache_query_frontend_lookup", server_ip)])
