Logs & monitoring
Two console tabs cover observability, but they observe different things. Log Viewer is for the logs you store in Arc. Monitoring is Arc's own self-observability.
Log viewer
The Log Viewer tab reads the log data you've ingested into Arc: application logs, structured events, anything you write to a log measurement. Point it at your log tables and slice through them without writing the SQL by hand.
It adds tooling on top of the raw rows:
- Pattern detection: surfaces recurring shapes across your log lines so you can spot what's noisy.
- Trace extraction: pull the entries that belong to a trace together, for following a request across services.
This is the right tab when you need to see what your application is doing, as recorded in Arc.
Monitoring
The Monitoring tab is Arc's own self-observability: how the instance itself is doing, right alongside your data.
It shows the instance's operational signals: ingestion throughput, query activity, and internal metrics. Use it to answer "is Arc healthy and keeping up?" rather than "what's in my data?".
- Log Viewer → the logs your systems write into Arc.
- Monitoring → how the Arc server is performing.
