How to control console log level/format?

[themalkolm]

Hey, is it possible to disable curses UI completely and simply output logs on stdout?

[nicolargo]

With Glances 2.5 or higher, you can use the --quiet option to disable the curse interface.

OK, I got the quiet option. But how to do this combo:

1. Disable curse interface
2. Redirect log to console and control it's level (DEBUG/INFO/...)

[themalkolm]

Hm, I see that default log level for console is CRITICAL and no way to change it. Is it possible to provide custom logging.conf somehow?

[themalkolm]

Just to give the context. I'm evaluating glances if it could be used on Windows as collectd-like daemon to send metrics to statsd server. So, I can disable curses UI - check. Now the question how to control console logs format/level/etc.

And to save some time, is there any support for adding plugins via cfg somehow? I understand that I can add them to plugins folder and rebuild the project. But it would be nice to somehow use the version from pip and simply configure to have extra plugins.

Why don't you use directly the statsD plugin to populate your StatsD database ?

1. --export-statsd works fine, no problems here. Exports as expected.
2. I want to have glance logs being printed to stdout (surely with disabled curses UI) and somehow control their format.
3. I would like to implement custom plugins and this way extend exported metrics whenever required.

[nicolargo]

1. You can have a look in the https://github.com/nicolargo/glances/blob/develop/glances/core/glances_logging.py file in order to change the log/format.
2. All the plugins are exported. So if you add a new plugin to the https://github.com/nicolargo/glances/tree/develop/glances/plugins folder it should work. Best way to processed to write a new plugin is to start from an existing one and adapt to your needs. The plugin file should be named glances_xxx.py (where xxx is your plugin name).

Perhaps you can describe what kind of new metrics do you need ?

[nicolargo]

@themalkolm any head up ?

I plan to make the Glances logging system configurable through the configuration file. Is it responding to yours needs ?

[themalkolm]

@nicolargo yes, this will solve logging issue. I would say an essential part of any headless daemon.

[nicolargo]

Implementation done through the issue #900 .

Read the doc https://github.com/nicolargo/glances/blob/develop/docs/config.rst#logging to configure your own logger.

Thanks!
