Settings

Argument boxfuse.conf property Default Description
-env=... env dev Select the specified environment (ex.: test or prod)
-logs.boot logs.boot false Shows the instance boot logs instead of the application logs
-logs.filter.FILTER=value logs.filter.FILTER

CloudWatch Logs apps only

The filter to apply when viewing the application logs.

Supported filters:

Name Description Example
instance Only show logs for the instance with this id i-12345678
image Only show logs for instances of this CloudCaptain image myuser/myapp:123
app Only show logs for instances of this CloudCaptain app myuser/myapp
level Only show log events at this log level or higher (possible values: TRACE,DEBUG,INFO,WARN,ERROR) WARN
event Only show logs events with this exact event id USER_CREATED
logger Only show logs events with this exact logger com.myapp.MyClass
thread Only show logs events created on this exact thread main
account Only show logs events in relation to this account in the system my-account
action Only show logs events in relation to a domain-specific element in the system (like an customer order for example) order-12345
user Only show logs events in relation to this user of the account (for systems with the concept of teams or multiple users per account) MyUser
session Only show logs events for the session with this id session-9876543210
request Only show logs events for the request with this id req-111222333
message Only show logs events with this message my-log-message
limit Limit output to first n log messages where 1 <= n <= 10000 2500
start Limit output to log messages created after this date and time.

Supported date formats:

  • 2016-12-08 11:22:44
  • 2016-12-08 11:22
  • 2016-12-08
  • 11:22:44
  • 11:22

The space between date and time can also be replaced by the letter T like in standard ISO dates. Example: 2016-12-08T11:22:44

By appending Z to the time it will be treated as UTC instead of local time. Example: 2016-12-08 11:22:44Z

As an alternative to the absolute date/time you also have the option to pass in the relative number of seconds to the current time. Example: -600 (10 minutes ago)

2016-12-07 12:34:56
end Limit output to log messages created before this date and time.

Supported date formats:

  • 2016-12-08 11:22:44
  • 2016-12-08 11:22
  • 2016-12-08
  • 11:22:44
  • 11:22

The space between date and time can also be replaced by the letter T like in standard ISO dates. Example: 2016-12-08T11:22:44

2016-12-08 20:10:00

Wildcards: Wilcard matching is supported by prepending and/or appending an asterisk (*) to the filter value. Examples:

*abc match all ending with abc
abc* match all starting with abc
*abc* match all starting or ending with abc

Important note for Linux and macOS users: when using wildcards the argument should be enclosed in single quotes.
Example: '-logs.filter.message=*my text to match*'

-logs.layout=... logs.layout timestamp app? image? instance? event? 40:logger? 10:thread? account? action? user? session? request? message?

CloudWatch Logs apps only

The layout to use when displaying the logs.

Format:

  • All fields are separated by a single whitespace and are variable-width by default
  • Appending ? to the field name hides the field if a filter matches it exactly
  • Prepending a number and a column (example: 10:) left trims or left pads the field to that length
  • Appending a number and a column (example: :10) right trims or right pads the field to that length
  • Valid field names: level, timestamp, app, image, instance, event, logger, thread, account, action, user, session, request, message

Example: level:5 image logger?:30 10:thread shows 4 fields:

  • level fixed width of 5, right padded or right trimmed if necessary
  • image variable width
  • logger fixed width of 30, right padded or right trimmed if necessary, hidden if matched exactly in filter
  • thread fixed width of 10, left padded or left trimmed if necessary
-logs.tail logs.tail false Tail (keep running with live updates) the logs
