Online Troubleshooting and Retrospective for Log Platforms and Observability: Conversation Logs and Auditing

This category of data primarily comes from logging systems, distributed tracing platforms, Metrics systems, and application SDKs. It is updated daily

What this category of data looks like

This category of data primarily comes from logging systems, distributed tracing platforms, Metrics systems, and application SDKs. It is updated daily or when a version is released. Daily supporting documents include logging collection specifications, distributed tracing instructions, metric dictionaries, and dashboard configuration records. Data fields include timestamps accurate to the millisecond, unique session identifiers, user question content, model response content, error stack fragments, distributed trace IDs, and associated metric snapshots. The size of a single log entry typically does not exceed 100 KB.

Constraints imposed on conversation logs and auditing processes

The scattered nature of data sources requires that the conversation log auditing process use chatId and responseChatItemId to associate logs and interaction data across different systems, to avoid isolated troubleshooting clues. Differences in update frequencies require that audit data be archived daily or packaged and retained with versions, to ensure the completeness of cross-version fault retrospectives. The variety of supporting documents requires that configuration items match the field naming rules in logging collection specifications; otherwise, field parsing failures will occur. The multi-field raw data also requires that the auditing process configure field filtering rules to retain only content strongly related to conversation interactions, to reduce the overhead of audit storage and retrieval.

Configuration Guidelines

The following configurations apply to FastGPT v4.17.0.

Configuration ItemRecommended SettingRationale
chatId association switchEnabledEnsures logs and conversation sessions across different systems are bound, resolving issues with scattered data association
responseChatItemId log bindingEnabledAccurately associates individual conversation replies with corresponding observability data, narrowing troubleshooting scope
Audit log retention period30–90 daysCovers the retrospective cycle of most online faults, while controlling storage costs
Field filtering rulesRetain only conversation content and error stacks in the detail fieldReduces redundancy in audit data and improves retrieval efficiency
Archiving trigger conditionTriggered daily on a scheduled basisMatches data update frequencies to ensure timely retention of audit data
Log sampling strategyFull collection of the first 1000 sessions, 10% sampling for remaining sessionsBalances audit completeness and storage overhead

Three Common Configuration Mistakes

  • Symptom: The detail field in conversation audit logs is empty, making specific interaction content unviewable. Cause: The logging collection switch for conversation content is not enabled, or the collection fields for conversation content are not configured in the collection specification.
  • Symptom: Unable to associate corresponding distributed tracing data when troubleshooting across sessions, leading to excessively long fault localization time. Cause: The chatId association configuration is not enabled, causing logs and conversation sessions across different systems to fail to bind.
  • Symptom: Retrieval response speed for old conversation windows is significantly slower than for new windows. Cause: Audit logs do not have reasonable field filtering rules configured, causing excessive redundant observability data to be loaded during retrieval.

How to Confirm Configuration Completion

  • Manually initiate a test conversation, check whether the corresponding chatId and detail field content is included in the audit logs.
  • Import a session identifier from a historical fault, verify whether corresponding logs, distributed tracing data, and metric data can be associated.
  • View the audit storage usage, confirm whether it matches the preset retention period and storage threshold.
  • Trigger a simulated fault, check whether the corresponding error stack and interaction context can be found in the audit logs.
