NAME

tlog-rec-session.conf - tlog-rec-session configuration file

DESCRIPTION

tlog-rec-session.conf is a JSON-format configuration file for tlog-rec-session program. Contrary to the strict JSON specification, both C and C++ style comments are allowed in the file.

The file must contain a single JSON object with the objects and fields described below. Almost all of them are optional and assume a default value. However, those that do require a value can still be omitted and specified to tlog-rec-session in other ways: through environment variables or command line.

OBJECTS AND FIELDS

Root object

shell (string): The path to the shell executable which should be spawned.

Minimum: 32
Default: 2048

limit (object): Logging limit object, see below.
file (object): File writer object, see below.
syslog (object): Syslog writer object, see below.

A configuration specifying only a shell:

{
    "shell": "/usr/bin/zsh"
}

A configuration enabling logging user input:

{
    "log": {
        "input": true
    }
}

A configuration specifying logging to a file:

{
    "writer": "file",
    "file" : {
        "path": "/var/log/tlog-rec-session.log"
    }
}
