3.1 Global Configuration

The global configuration file contains a small set of options that are usually required for a normal EMT installation. It's divided into sections that are denoted by square brackets. The [global] section contains configuration directives that aren't program or plugin-specific. Here is the example file ‘emt.cnf’:

[global]
extra_config_dir=/etc/emt.d/
gather_time = 60

[emt_gather]
field=timestamp
field=hostname
output_handler=local_text

[local_text]
output_file=/var/tmp/emt

[emt_view]
default_view = default

This file also includes configuration for EMT programs such as emt_view as well as configuration of the default output handler local_text. Program configuration and output handler configuration can be moved into the extra configuration directory. Internally, all the configuration files are read together as one.

The [emt_gather] section is special in that it defines fields to be gathered and the output handler(s) to send those fields to. By default, all fields are sent to the local_text output handler, which writes them to a file. The [local_text] section defines parameters for the local_text output handler. If there isn't an output_handler=local_text line in the [emt_gather] section, the [local_text] section is ignored.
