Tab Protocols

This is where system messages are displayed. The newest one is at the top. If something isn't working, this is the first place to check.

If the "Logs" menu item appears red, there is an error. The number next to it indicates the number of logs.

The toolbar

1Update log.
2Pause output. Instead of the symbol, the number of new, undisplayed messages will appear. Useful if you want to read a specific line at your leisure.

5Show/hide process ID.
6Show/hide colors : highlights errors in red and warnings in yellow.
7Reverse output direction : newest message at the top or bottom.

9Display errors and warnings.
10Download log : downloads the complete daily file/opt/iobroker/log .

The host is located to the right of this. In a multi-host system , this is where you switch between hosts. Only the messages from the selected host are displayed.

The list

Die Protokollliste mit Quelle, Zeit, Stufe und Nachricht

The columns are source (the instance or host), time , log level , and message . The fields in the header allow filtering: by source, by minimum log level, and by text within the message.

Log levels from most detailed to most concise:

LevelFor what
silly (in the dialogue Everything )Absolutely every single report. Only ifdebug is not enough.
debugInternal processes too. For troubleshooting, then reset.
infoThe normal procedure: Start, Stop, Connections.
warnSomething is unusual, but it continues.
errorSomething went wrong.

The level is set for each instance in the Instances tab, and the default for new instances is set in the system settings .

Long lines are truncated in the list. Anyone who wants to get to the bottom of a message should download the log file and look there. Often the actual cause is in the lines preceding it.

If there is an error in the log

Two things almost always help:

  1. Look for the first error message, not the last. One error often leads to further errors; the beginning of the chain is what's interesting.
  2. The log level of the affected instance is atdebug Try restarting the instance and reviewing the messages again.

If that doesn't help, the forum can help. The relevant post should be an excerpt from the downloaded log file, not a screenshot of the list.
