Add a built-in trace interceptor for keeping traces depending of their latency #8040

cecile75 · 2024-11-29T16:22:34Z

What Does This Do

Add the possibility to enable a latency trace interceptor

This latency trace interceptor is disabled by default.
We can activate it by setting the value of dd.trace.experimental.keep.latency.threshold.ms or DD_TRACE_EXPERIMENTAL_KEEP_LATENCY_THRESHOLD_MS to a positive value
This value should be in milliseconds and this interceptor will retain any local trace who has a root span duration greater than this value.
The activation of this interceptor is ignored if partial flush is enabled in order to avoid incomplete local trace (incomplete chunk of trace).
Note that since we're changing the sampling priority at the end of local trace, there is no guarantee to get complete traces,
since the original sampling priority for this trace may have already been propagated.

Usage

Environment Variable: DD_TRACE_EXPERIMENTAL_KEEP_LATENCY_THRESHOLD_MS (system property: dd.trace.experimental.keep.latency.threshold.ms)

Must be set alongside environment variable DD_TRACE_PARTIAL_FLUSH_ENABLED=false (system property dd.trace.partial.flush.enabled=false)

Default: 0 (Disabled)

Description: This value should be in milliseconds, any local traces who has a root span duration greater than this value will be retained via MANUAL_KEEP.

Motivation

APMS-14002

You do not need to set a negative default. I also would have ensured the minimum is strictly above 0

If the latency is in nanoseconds it must be a long instead. an int will be too little to hold more than a couple of seconds and will overflow

LGTM just one comment about having this as "experimental" since it can cause broken traces and is not intended to be publicly documented at this point

Also, since this config would likely trace back to this PR in google search, we should also update the PR description with a Usage section that describes the config similar to how configs appear here

### Bugfixes - AWS SDK for Java 1.x now includes additional validation for Amazon S3 client APIs to handle scenarios where an empty string ('') is passed as the key argument to the following operations: PutObject, DeleteObject, ListObjects, GetObjectMetaData, ListObjectsV2, SetObjectTagging, GetObjectTagging, SetObjectAcl, GetObjectAcl, SetObjectLegalHold, GetObjectLegalHold, CopyObject, CopyPart, SelectObjectContent, SetObjectRetention, GetObjectRetention, AbortMultipartUpload, CompleteMultipartUpload, InitiateMultipartUpload, ListParts, UploadPart, RestoreObjectV2, and RestoreObject. The SDK will validate the key argument and throw an exception if it is an empty string, ensuring correct and expected behavior. </details> --- ### Configuration 📅 **Schedule**: Branch creation - "after 6pm every weekday,before 2am every weekday" in timezone Australia/Melbourne, Automerge - At any time (no schedule defined). 🚦 **Automerge**: Disabled by config.
