Limit writer logs only when LLMObs is enabled #9781

daniel-mohedano · 2025-10-16T15:34:14Z

What Does This Do

Limits LLM Obs logging to cases where agentless is being forced.
Refactors the logic for easier following.

Motivation

The logging was performed whenever EVP Proxy was not supported, independently of LLM Obs being enabled or not.

+    boolean useProxyApi = false;
+
+    if (TrackType.LLMOBS == trackType) {
+      useProxyApi = evpProxySupported && !config.isLlmObsAgentlessEnabled();


The !config.isLlmObsAgentlessEnabled() check can be done once for clarity.
