Sparkplug SiteWise Bridge is configured with a configuration file on the filesystem of the EC2 instance. If you are unfamiliar with how to access the instance see this page for access instructions. Also note, after modifying the configuration the application must be restarted. This can be done with the following command.
| Code Block | ||
|---|---|---|

sudo /etc/init.d/ssb restart |
The path to the configuration file is:
...
Once you open the file, you will see the following options.
