[en] Logs

[en] Every action executed on the platform is saved on log files. These logs can then be consulted to see detailed information about transactions, services and every object that exists within VT-NET.

[en] To access the logs folder, go to /veritran/vt-net/log/ . Processes on a node save updates on the same file. You can identify it with the name of the environment, node and the .log extension, i.e VTRP_NDA1.log

Nota

[en] This is the default path to consult log files. Since paths can be modified during the platform's installation, it is advised to double check you are accessing the logs folder with the correct path.

[en] To consult a log, type vi and the name of the log. To improve its readability, use the set nowrap function. See an example below.

Read Log Realms to learn how to increase and decrease log levels for specific objects within VT-NET.
