The Warning and Errors Tab
- Marc Lievin
In a distributed simulator, there is an error tab for every node. Each node is represented by its host name and process ID. The tag [local] indicates the process running this page.
The log level can be set per node to the following values, be severity:
- Off - nothing will be logged
- Fatal
- Error
- Warn
- Info
- Debug
- Trace
- All - everything will be logged
The log level corresponds to the threshold to which messages are displayed. For example, setting the level to Info will also display warnings and errors.
When the settings are at a lower severity (info or debug), there might be a lot of logging on multiple nodes. To limit the network traffic, the broadcast of errors is not enabled by default. It can be turned ON on specific nodes by selecting Enable network dispatch of errors on the appropriate tab. Those nodes will then broadcast their log across the network. This means that the nodes tabs will be updated, until the checkbox is unchecked again.
Reviewing warning and errors can help improve the efficiency and resolve issues where the simulation fails to load.
