OpenMetrics Source Demo

In order to run the demo, from this directory, run

go run github.com/stripe/veneur/v14/sources/openmetrics/demo

In the output, you should see

• a counter demo_sample_counter, that increments once per flush interval
• a gauge, demo_sample_gauge, that cycles through the values 1, 5, 4, 6, 2, and 3.
• a histogram, demo_sample_histogram, that aggregates the values from the sample gauge into three buckets: ≤ 2.0, ≤ 5.0, and ≤ +∞.
• a summary, demo_sample_summary, that captures the 50th and 84th percentiles of a normally distributed random variable with a mean of zero and standard deviation of 10, sampled once per flush interval. The 50th percentile should converge to zero and the 90th percentile should converge to approximately 12.8.
