Installation and configuration

To install see Getting Started.

Troubleshooting & debugging

The application has structured logging capability, the first port of call for a crash is probably the Vega and Tendermint logs which are available on the console if running locally or by journal plus syslog if running on test networks. Default location for log files:

• /var/log/vega.log

Each internal Go package has a logging level that can be set at runtime by configuration. Setting the logging Level to -1 for a package will enable all debugging messages for the package which can be useful when trying to analyse a crash or issue.
