bl logs

View logs for a resource

​
Synopsis

View logs for Blaxel resources. The logs command displays logs for agents, jobs, sandboxes, and functions. You must specify both the resource type and resource name. Resource Types (with aliases):
  • sandboxes (sandbox, sbx)
  • jobs (job, j, jb)
  • agents (agent, ag)
  • functions (function, fn, mcp, mcps)
Sandbox Process Logs: For sandboxes, you can view logs for a specific process by adding the process name: bl logs sandbox my-sandbox my-process Job Execution Logs: For jobs, you can filter logs by execution ID and task ID: bl logs job my-job my-execution-id bl logs job my-job my-execution-id my-task-id Time Filtering: By default, logs from the last 1 hour are displayed. In follow mode (—follow), the last 15 minutes are shown as context, then new logs are continuously streamed in real-time. You can customize this by:
  • Using duration format (e.g., 3d, 1h, 10m, 24h) with —period flag
  • Using explicit start/end times with —start and —end flags
  • Maximum time range is 3 days
Duration units:
  • d: days
  • h: hours
  • m: minutes
  • s: seconds
Timestamps: By default, logs are prefixed with their timestamp in local timezone. Use —no-timestamps to hide them, or —utc to display timestamps in UTC. Severity Filtering: By default, all severity levels are shown. Use —severity to filter by specific levels. Available severities: FATAL, ERROR, WARNING, INFO, DEBUG, TRACE, UNKNOWN Use comma-separated values: —severity ERROR,FATAL Search: Use —search to filter logs by text content. Only logs containing the search term will be displayed. Examples:

​
View logs for a specific sandbox (last 1 hour - default)

bl logs sandbox my-sandbox

​
View logs for a specific process in a sandbox

​
View all logs for a job

bl logs job my-job

​
View logs for a specific job execution

bl logs job my-job exec-abc123

​
View logs for a specific task within an execution

bl logs job my-job exec-abc123 task-456

​
Follow job execution logs in real-time

bl logs job my-job exec-abc123 —follow

bl logs job my-job —period 3d

​
View logs for a specific time range

bl logs agent my-agent —start 2024-01-01T00:00:00Z —end 2024-01-01T23:59:59Z

​
Hide timestamps in output

bl logs agent my-agent —no-timestamps

​
Show timestamps in UTC

bl logs agent my-agent —utc

​
Filter by severity

bl logs agent my-agent —severity ERROR,FATAL

​
Search for specific text in logs

bl logs agent my-agent —search “error”
