application insights SLA

    Question

  • I noticed that in application insights SLA V1.0and v1.1, it says We guarantee that the data latency of the Application Insights Service will not exceed two hours 99.9% of the time. , so in the left 0.01% of time outside the SLA, could the the data (send by trackTrace() or trackEvent() etc.) would be losted? or definitely sent to application insights (2 hours later)?

    And in the latest version v1.2, it changes the Data latency SLA to Query availability SLA, what is the difference between the change?

  • Hello,

    For the first part of your question, yes, that data would be sent to Application Insights later than 2 hours. This is a distracting and common question, while most of the data has a latency of under 5 minutes, some data can take longer; typically larger log files. While this can help drive the conversation on latency, and help customers understand why alerting on a metric is faster than alerting on data in a log file, it also gave an impression that Application Insights is taking nearly 2 hours to ingest data.

    The updated SLA changes this to Query Availability, your data will be available to you. Then we have a feature planned so you can query your data latency, although I don't have an ETA for this yet.

    Thanks for using Application Insights!
