/etc/dag-agent/config.yaml.
| CLI | Env var | Config key | Default | Purpose |
|---|---|---|---|---|
-s | DAG_SHIP_URL | ship_url | unset = file mode | Full HTTPS ingest URL, including the /ingest path (e.g. https://<name>-ingest.hilt.ai/ingest) — the agent POSTs to it verbatim. Unset = file mode. |
-o | DAG_OUTPUT_PATH | output_path | /var/log/dag-agent/events.jsonl | JSONL output. Set to - for stdout explicitly. |
-n | DAG_NODE_ID | node_id | $(hostname) / spec.nodeName on K8s | String host label displayed on the dashboard. |
-b | n/a | n/a | off | Benchmark mode; ship only. |
-v | n/a | n/a | off | Verbose: mirror events to stderr. |
-V | n/a | n/a | n/a | Print version and exit. |
| n/a | n/a | cpu_limit | no limit | Written as CPUQuota= in the systemd drop-in. |
| n/a | n/a | ram_limit | no limit | Written as MemoryMax= in the systemd drop-in. |
| n/a | n/a | ringbuf_size | 1M | Per-CPU BPF ring buffer size. Increase on busy hosts (8M, 16M). |
| n/a | n/a | tag_refresh_interval_s | 1800 (30 min) | How often to re-poll cloud instance-metadata tags without a restart. 0 disables periodic polling. systemctl reload always triggers one immediate refresh regardless. Works on both EC2 and EKS (requires instance_metadata_tags enabled on the instance/launch template). |
| n/a | DAG_HOST_PROFILE | n/a | balanced | Attach profile: latency_critical | balanced | diagnostic. latency_critical sheds optional probes. Invalid values refuse startup. |
| n/a | DAG_CONTENT_INSPECT | n/a | off | Opt-in. When 1/true/yes/on, copy the source file of a DATA_FLOW to a public destination (capped at 100 MiB) into in-tenant object storage for File Detail. Never started under DAG_HOST_PROFILE=latency_critical. File bytes never ride Kafka. Default off. |
