Show Percentiles Across Multiple Buckets
Query
logscale
bucket(span=60sec, function=percentile(field=responsetime, percentiles=[50, 75, 99, 99.9]))
Introduction
Show response time percentiles over time. Calculate percentiles per minute by bucketing into 1 minute intervals:
Step-by-Step
Starting with the source repository events.
- flowchart LR; %%{init: {"flowchart": {"defaultRenderer": "elk"}} }%% repo{{Events}} 0{{Aggregate}} result{{Result Set}} repo --> 0 0 --> result style 0 fill:#ff0000,stroke-width:4px,stroke:#000;logscale
bucket(span=60sec, function=percentile(field=responsetime, percentiles=[50, 75, 99, 99.9]))
Using a 60 second timespan for each bucket, displays the
percentile()
for the responsetime field. Event Result set.
Summary and Results
The percentile()
quantifies values by
determining whether the value is larger than a percentage of the
overall values. The output provides a powerful view of the
relative significance of a value. Combined in this example with
bucket()
, the query will generate buckets of
data showing the comparative response time for every 60 seconds.
