If your log file is in a custom JSON format, you will need to use the LogViewPlus JsonParser. The parser wizard can help you configure the JsonParser, but to do this you will need to enter a sample log entry. This screen can be used to input your sample JSON log entry. Once entered, the sample entry will be parsed to ensure that it is valid JSON. In the above example you can see a "JSON parsed successfully" message at the bottom of the screenshot. If the JSON was invalid an error message would have been displayed instead. You must enter a valid JSON log entry before continuing to the next step.
