Name

aspire logs - Display logs from resources in a running apphost.

Synopsis

aspire logs [<resource>] [options]

Description

The aspire logs command displays console logs from resources in a running AppHost. You can view logs for all resources, filter to a specific resource, follow new log entries in real time, and choose table or JSON output for automation.

When executed without the --apphost option, the command:

Scans for all running AppHost processes.
If multiple AppHosts are running within the current directory scope, prompts you to select which one to target.
If only one AppHost is running in scope, connects to it directly.
If no in-scope AppHosts are found but out-of-scope AppHosts exist, displays all running AppHosts for selection.
