Link to failing step log: https://luci-logdog.appspot.com/v/?s=chrome%2Fbb%2Fchromium.perf%2FAndroid_Nexus5_Perf%2F161%2F%2B%2Frecipes%2Fsteps%2Fsystem_health.memory_mobile_on_Android%2F0%2Fstdout

This isn't a normal failure: it looks like it's a Telemetry/infra failure related to not being able to find some file. Where I'd expect to normally see on the luci page the list of failing stories, I'm instead seeing "TEST RESULTS WERE INVALID".

An excerpt from the logs is:
