RUM Network

The Network tab surfaces API and network performance from the mobile client's perspective - what your app actually experienced, not what your backend logs say it sent.


Avg Response Time by Endpoint

Avg Response Time by Endpoint (top 10) chart with Name/Min/Mean/Max table

A time-series chart of the top 10 endpoints by response time, with a Name / Min / Mean / Max table underneath so you can spot both a slow trend and its worst-case latency per endpoint.


All Endpoints

All Endpoints table with URL, Method, Avg Duration, Error Rate, and Requests columns

A table of every endpoint the app called:

ColumnDescription
URLThe endpoint path
MethodHTTP method
Avg DurationAverage response time
Error RatePercentage of requests that failed
RequestsTotal request count

Sort by Error Rate or Requests to find the endpoints worth investigating first.


Failed Requests

A table scoped to just the failing calls: URL, Method, Status, Occurrences, and First/Last Seen - useful for catching an endpoint that's failing consistently even if its overall request volume is low enough to not stand out in All Endpoints.


Filters

Network adds HTTP-specific attributes to the shared Filters sidebar: http.host, http.route, http.method, http.status_code, and network.connection.type - use these to scope every panel above to a specific host, route, verb, status class, or connection type.


Use Cases

Finding a Slow Endpoint

  1. Check Avg Response Time by Endpoint for the top 10 offenders
  2. Cross-check All Endpoints, sorted by Avg Duration, for anything outside the top 10 that's still slow relative to its request volume

Catching a Silently Failing Endpoint

  1. Sort All Endpoints by Error Rate
  2. Open Failed Requests and filter by http.route to confirm the failure pattern (a specific status code, a specific host)

  • Sessions - See individual http.request events in context
  • Screens - Screen-level performance, for issues that aren't network-bound
