Actinia supports logging to fluentd as well as to stdout.

tl;dr:

  • Rename logfile in actinia.cfg in project setups from worker_logfile = /actinia_core/workspace/tmp/actinia_worker to worker_logfile = /actinia_core/workspace/tmp/actinia_worker.log. If you leave it, it won't break something but would be nice for consistency.
  • Adjust logging config as wished (fluentd/stdout with json/stdout colored). If your setup includes Kibana, log_stdout_format = json is recommended while log_stdout_format = colored provides better human readability. More infos below.

Standard Output Logging Infos

Configuration

Example:

[LOGGING]
log_interface = stdout
log_stdout_format = colored
log_file_format = colored
log_stderr_format = plain
log_level = 4

The log_interfaces fluentd and stdout are mutually exclusive, while actinia will always log to a file. If log_interface = stdout, it can be chosen between json output (e.g. for kibana) and colored for human readability. The log_file_format has the same options and is independent. The option log_stderr_format is useful for debugging and won't appear in fluentd. In case this is a stacktrace, it is logged line by line, each wrapped by the log formatter (either json or stdout, depending on which one is set). As it is hardly readable and context can get lost, only use with json when needed by e.g. kibana, else use option plain for a readable stacktrace. It will also log to file with configured formatter and log level CRITICAL.

For more information, see https://github.com/mundialis/actinia_core/blob/master/src/actinia_core/resources/common/config.py#L132.

Dev / Debug Hints

  • one disadvantage of general actinia logging implementation is, that log messages are passed to redis_fluentd_logger_base where they are initially logged. This way, it always logs as source /usr/lib/python3.8/site-packages/actinia_core-0.99.5.post0.dev18+g4d82691.dirty-py3.8.egg/actinia_core/resources/common/redis_fluentd_logger_base.py:104 instead of where the message was generated. To change this, refactoring would be necessary.
