SLI Set up

[anjeleepadayachyHO]

How do teams know what percentage of error to set their SLI's. There should be a level of guidance, as 99.99% doesn't mean that you are measuring the performance of your service realistically or cost effectively. Not all services need that level of accuracy, (unless they are a critical service), as it might cost you more in resource power to keep the service to that level or there may be know issues/ dependency that until they are resolved your service will not be performing to that level to consider.

Business strategies and priorities are continually changing, therefore you will also need to ensure that SLI's are continually reviewed when set up. Primarily collate data for a month and review, once you are confident that the SLI's are at the correct threshold, review every 6 months, continually aligning business priorities.
