## What the models said for it

- "Deeply invested in Elastic or Grafana ecosystems → Logstash or Grafana Alloy" (DeepSeek V4 Flash, Telemetry pipelines)

## And against it

- "Avoid deploying Logstash directly on application nodes as a local shipper. Logstash can have a massive memory footprint and slow startup times" (Mistral Small, Telemetry pipelines)
- "running full Logstash as a local shipper): High memory footprint, slow startup, and resource contention with your apps" (Grok 4.20, Telemetry pipelines)
- "Avoid deploying heavy processing agents like Logstash directly onto application nodes as local shippers." (Qwen 3.7 Flash, Telemetry pipelines)
- "Avoid heavier options like Logstash (higher resource use)" (Grok 4.20, Telemetry pipelines)
