Cloud Logging

A Google Cloud project can be switched live, and ObjectExplorer tails Cloud Logging into a local store: the tail belongs to the app, not to the window, so it keeps collecting while you are elsewhere and is still there after a restart. The tree under the project is the one the logs describe — resource type, resource, then the single service.

Log files that a sink already exported to a bucket open the same way. Point at one NDJSON object, or at the whole YYYY/MM/DD prefix, and the viewer walks it newest first. Cloud Logging entries and OpenTelemetry records both read as the same rows.

The viewer

• A timeline you can grab — one bar per slot, grey for ordinary lines, orange for warnings, red for errors, so a burst of errors is a red block. Drag to pick a range, click a bar for that slot, zoom and step window by window.
• Two trees over the same lines — source answers "which service wrote this", trace answers "what happened during this request", drawn as a waterfall of spans by duration.
• Filter as you read — severity chips and text search narrow the rows, never the shape of the timeline you are aiming at.

Next: every format.
