Open tracing sounds nice, what info is passed along?

  My question is what conversation has there been re: Opentelemetry, the successor to OT
  • bostonsre 5y ago
    It sounds like ot is still in beta (but it's a little confusing that they're 1.0 but it has a message saying they're in beta on their main page). It looks like it's being adopted by a few larger app monitoring products, wondering if datadog will follow suit or if they will stick with open tracing and their custom implementations for logging and metrics. I assume they will support ingestion from ot at some point though. It sounds neat tho, will definitely read up on it more.

  You can pass along timing data from every aspect of the request [1] currently there are approximately 20 events supported. You can also send over just about anything that can be stored within an HAProxy variable / header through a tag. Here's an example configuration for HAProxy (simple) [2] (advanced) [3] and the OpenTracing specific configuration (simple) [4] (advanced) [5]. I've included both simple and advanced configurations.

    Yea, it's pretty flexible and you can attach any additional metadata that you want (e.g. app version info, user name).
