ConfigProvider iterates over all sources and reports all non-null values to telemetry #9404

mtoffl01 · 2025-08-21T18:55:59Z

What Does This Do

Previously, telemetry was only being reported for the ConfigSource that set the final value of the configuration. This PR introduces reporting telemetry for all ConfigSources that have non-null values set, regardless of whether it sets the final configuration value or not.

Summary of Changes:

ConfigCollector
- Stores config telemetry payloads of Map<ConfigOrigin, Map<String (configName), ConfigSetting>>
- Deprecates old put method in favor of a new put method with seq_id field
- New putDefault method is created to ensure originally reported defaults are not overwritten. Use cases:
  - ConfigProvider methods getEnum, getIntegerRange, getSet and getList invoke getString, which erroneously reports defaults as null under the hood
  - when a Config is already processed by the ConfigProvider, then a function like isExplicitlyDisabled is called and invokes getBoolean without the proper default value, which previously would override the DEFAULT telemetry payload with null.
ConfigSetting
- New field seqId and new of function that takes it in as a parameter
ConfigProvider
- All methods querying ConfigSources start from lowest priority to highest priority. A local seqId is used to track priority of ConfigSources that are set. In the case of parsing errors, there may be re-reporting of the last valid ConfigSource to ensure the highest priority and valid ConfigSource is reported with the highest seqId
- ConfigValueResolver
  - Helper class to help with re-reporting configurations. Includes key, value, seqId, and ConfigOrigin.
  - All ConfigProvider methods now store the final return value through ConfigValueResolver
- ConfigMergeResolver
  - Helper class to help with merging maps from multiple sources

+  /** Helper class to store resolved configuration values with their metadata */
+  static class ConfigValueResolver<T> {


This class is not private in order to expose it for a unit test that is needed to complete code coverage. The unit test verifies that reReportToCollector is not invoked when origin == null, which should never happen since the method to create a ConfigValueResolver should only occur when no re-reporting is expected. This check is only here as a safety check against poor usage of the function.

If this method is not used anymore then I would remove it (this is internal code, so not covered by breaking changes)

+      ConfigCollector.get().put(APPSEC_ENABLED, asm.enabled, ConfigOrigin.REMOTE, ABSENT_SEQ_ID);


What do you think about adding an update method to ConfigCollector ? or maybe remotePut ?

The new method would just take a key and new value - the origin would always be ConfigOrigin.REMOTE and the sequence id would be absent.

This simplifies remote-config calls to ConfigCollector and also provides a clear code path for such calls...

Consider storing this as a static field, i.e.

private static final Function< ConfigOrigin, Map<String, ConfigSetting>> NEW_SUB_MAP = k -> new ConcurrentHashMap<>();

which you can then re-use here and in putDefault below.

This is only used by DynamicConfig to report remote config updates - so I would change this to be

Suggested change

public void putAll(Map<String, Object> configMap, ConfigOrigin origin) {

public void putRemote(Map<String, Object> configMap) {

and use ConfigOrigin.REMOTE to get the right sub-map to update.

+    for (Map.Entry<String, Object> entry : configMap.entrySet()) {
+      put(entry.getKey(), entry.getValue(), origin, ABSENT_SEQ_ID, null);


This breaks the atomicity of the previous implementation - i.e. with the new code if a remote config update happens at the same time the config is collected for telemetry then half of the remote config update could land in the outgoing batch and the rest would land in the subsequent batch. This could result in inconsistent data being shown in the UI.

I'll add an update to show how the atomicity can be kept with the new sub-map approach.
