Filebeat Conditional Output Routing Design Prompt
Route events from a single Filebeat to different Elasticsearch data streams, indices, or ingest pipelines based on conditions, so each log type lands in the right place with the right retention without running multiple agents.
- Claude
- ChatGPT
- Cursor
Open prompt - Advanced
Filebeat Filestream High-Volume Harvester Scaling Prompt
Scale the filestream input on high-volume hosts so thousands of active files are harvested promptly without exhausting file descriptors, stalling the scanner, or letting slow outputs starve the harvesters.
- Claude

- Cursor
Open prompt - Intermediate
Filebeat Timestamp and Date Parsing Design Prompt
Set @timestamp from the event's own log time — across mixed formats and timezones — so documents sort by when the event happened, not when Filebeat read them, without dropping unparseable lines.

- Cursor
Open prompt - Advanced
Filebeat Docker Autodiscover with Hints Prompt
Design a Filebeat Docker autodiscover configuration driven by container labels (hints) so per-service multiline, modules, and JSON parsing are applied automatically as containers come and go.

Open prompt - Advanced
Filebeat Throughput & Bulk Batching Tuning Prompt
Diagnose and raise end-to-end Filebeat throughput by tuning batch sizing, worker concurrency, flush cadence, and compression against the real bottleneck instead of guessing.
