We are encountering issues where response and outbound blocks are not being captured into ELK logs. Upon investigation, it appears that the root cause is related to heterogeneous data types in the adjacent structure. Specifically:
- The fields in the payload (e.g., customers, characteristics, order characteristics, party characteristics) often contain inconsistent name value types (e.g., string, date, or integer). This inconsistency leads to mapping exceptions, such as:
• Error Message: “Mapping exceptions cannot be changed from text to date” or similar illegal argument errors. - These errors prevent the indexing of certain fields, which means the affected logs are not recorded correctly.
- This issue is consistent across multiple services and log types for responses and outbound blocks. Despite configuring mappings at the event stream level, the data inconsistency at runtime causes these failures.
Request for Support:
We need guidance on how to handle such heterogeneous payloads in ELK. Specifically:
- How can we configure the mapping to handle dynamic or inconsistent value types without causing mapping exceptions?
- Are there best practices or tools within ELK to process and index such fields while preserving data integrity?
- Any recommended approaches for handling and visualizing these heterogeneous fields effectively?
Your insights and suggestions would be greatly appreciated.
Below are the error details we are getting from logstash logs.
