How to Correctly Frame and Calculate Latency SLOsCategory: Data
SLOs are an agreement on an acceptable level of availability and performance and are key to helping engineers properly balance risk and innovation.
Setting a latency SLO is about setting the minimum viable service level that will still deliver acceptable quality to the consumer.
But unfortunately, you lose the ability to determine when your data is lying to you — for example, when you have high (+/- 5% and greater) error rates that are hidden from you.
What’s absolutely critical for accurate analysis is that your histograms ensure a high number of bins and that you set your bins the same across all of your histograms.
This shows how the behavior of your system changes over time and can help to inform you on how to set your SLO thresholds.
