class BlobTimelineMetric(telemetry.web_perf.metrics.timeline_based_metric.TimelineBasedMetric)
    BlobTimelineMetric reports timing information about blob storage.
 
The following metrics are added to the results:
  * blob write times (blob_writes)
  * blob read times (blob_reads)

Methods inherited from telemetry.web_perf.metrics.timeline_based_metric.TimelineBasedMetric:
AddWholeTraceResults(self, model, results)
Computes and adds metrics corresponding to the entire trace.
 
Override this method to compute results that correspond to the whole trace.
 
Args:
  model: An instance of telemetry.timeline.model.TimelineModel.
  results: An instance of page.PageTestResults.
VerifyNonOverlappedRecords(self, interaction_records)
This raises exceptions if interaction_records contain overlapped ranges.
