# dlv-log(1)

Help about logging flags.

## NAME

dlv-log - Help about logging flags.

## SYNOPSIS

**dlv log \[flags\]**

## DESCRIPTION

Logging can be enabled by specifying the --log flag and using the --log-output flag to select which components should produce logs.

The argument of --log-output must be a comma separated list of component names selected from this list:

```
debugger	Log debugger commands
gdbwire		Log connection to gdbserial backend
lldbout		Copy output from debugserver/lldb to standard output
debuglineerr	Log recoverable errors reading .debug_line
rpc		Log all RPC messages
dap		Log all DAP messages
fncall		Log function call protocol
minidump	Log minidump loading
stack           Log stacktracer
```

Additionally --log-dest can be used to specify where the logs should be written. If the argument is a number it will be interpreted as a file descriptor, otherwise as a file path. This option will also redirect the "server listening at" message in headless and dap modes.

## OPTIONS

**-h**, **--help**\[=false\]\
 	help for log

## OPTIONS INHERITED FROM PARENT COMMANDS

**--accept-multiclient**\[=false\]\
 	Allows a headless server to accept multiple client connections via JSON-RPC or DAP.

**--allow-non-terminal-interactive**\[=false\]\
 	Allows interactive sessions of Delve that don't have a terminal as stdin, stdout and stderr

**--api-version**=2\
 	Selects JSON-RPC API version when headless. The only valid value is 2. Can be reset via RPCServer.SetApiVersion. See Documentation/api/json-rpc/README.md.

**--backend**="default"\
 	Backend selection (see 'dlv help backend').

**--build-flags**=""\
 	Build flags, to be passed to the compiler. For example: --build-flags="-tags=integration -mod=vendor -cover -v"

**--check-go-version**\[=true\]\
 	Exits if the version of Go in use is not compatible (too old or too new) with the version of Delve.

**--disable-aslr**\[=false\]\
 	Disables address space randomization

**--headless**\[=false\]\
 	Run debug server only, in headless mode. Server will accept both JSON-RPC or DAP client connections.

**--init**=""\

 	Enable debugging server logging.

**--log-dest**=""\
 	Writes logs to the specified file or file descriptor (see 'dlv help log').

**--log-output**=""\
 	Comma separated list of components that should produce debug output (see 'dlv help log')

**--only-same-user**\[=true\]\
 	Only connections from the same user that started this instance of Delve are allowed to connect.

**-r**, **--redirect**=\[\]\
 	Specifies redirect rules for target process (see 'dlv help redirect')
