Configuring Postgres Workload Report#

pwr configuration file#

To reduce the number of command-line arguments needed when executing pwr , you can use a configuration file to specify options that always have the same value but that value differs from the default.

During execution, pwr looks for an existing configuration file in ~/.pwr.conf and /etc/pwr.conf , in that order using the first one found. However, if the --config option specifies a configuration file, that overides the default locations.

The installation package creates a template for the configuration file in /etc/pwr.conf.templ . We recommend copying this file to one of the two places where pwr looks for a configuration file and editing the options in the template as necessary.

The following sections describe the options you can configure.

input_dir#

Identifies an existing directory where the edb_wait_states contents of a Lasso report are located. This option is used mainly for pwr report execution (see Using Postgres Workload Report ).

output_dir#

Specifies where reports are outputted. During execution, Postgres Workload Report tries to create the directory if it doesn’t exist.

report_name#

Provides the name of the report files generated. Usually, this option is specified from the command line because different reports typically have different names.

log_file#

Provides the full path to the file where pwr writes the stdout and stderr logs.

log_level#

Specifies the logging level to use when running Postgres Workload Report. Valid values are, from more verbose to less verbose:

DEBUG INFO (default if not specified) WARNING ERROR CRITICAL

See the Python logging documentation for more information about log levels.

log_format#

Provides the format of the log messages that are written to the log file. See the Python logging documentation for more information on log formatting.

assets_dir#

Identifies the directory where you can find the jinja templates used to format the HTML output and the CSS used for PDF output. Typically, the directory you may want to use by default is /usr/share/pwr/assets , which contains the assets provided with the edb-pwr package.
