DynamicGroupController and attributes

[tunnus]

Trying to set log level for MQTT to the lowest possible, is it in practise level 4? Also, would like to set maximum size and log rotation, but the following setup in logging.yaml did not work:

MQTTController:
    level: 4
    streams:
      - type: file
        maxsize: 2  
        keep: 2

Using the latest build (23010).

Four (4) is the default level, which logs information and more severe messages. The severities are critical (0), error (1), warning (2), notice (3), information (4), and debug levels 5 through 9 inclusive.

Good on you for showing the config so, but from the posting guidelines:

... if you say "I tried to do X but it didn't work", you need to show what you tried to do, and you need to explain what you expected, what happened, and how that didn't meet your expectations

Okay, if I ask the other way around, so if max size & rotation for the "main" log file is set as shown below, how do you set the same for MQTTController?

logging:
  default:
    level: 4
    streams:
      - type: console
        level: 0
      - type: file
        name: "reactor.log"
        maxsize: 2  # megabytes max size
        keep: 5     # copies of old logs

Just the way you've done it. I'm still wanting some narrative of what you expected to see vs what is happening, because I think just you thinking about how to write that might have led you to solving your own problem.

I'm pretty sure it's as simple as, you haven't told the configuration what file to send the log to... you need to add a name field in streams for the MQTTController section, so it knows what file name to use for that log stream.

  MQTTController:
    level: 4
    streams:
      - type: file
        name: mqtt.log
        maxsize: 2  
        keep: 2

If you don't want it to log to a separate file, just the regular reactor.log file (i.e. you only want to change MQTTController's log level, not its output destination), then remove the entire streams section from your MQTTController section, so it's just:

  MQTTController:
    level: 4

I thought you wouldn't have to specify a name for the file as so far MQTT controller has logged to a file "mqtt-topics.log"

Now I have the following configuration, but the file grows over 4 MB (does not rotate)

MQTTController:
    level: 4
    streams:
      - type: file
        name: mqtt-topics.log
        maxsize: 4 
        keep: 2 

Just realized I have "log_topics" in reactor.yaml's mqtt section which may or may not interfere with this logging setup?

@tunnus topic logging is separate. Remember that 4MB is 4,194,304 bytes, not 4,000,000. The last message logged before rotation may cause the file to be slightly larger.
