However, when I add the data to a metrics index, I see nothing. I got no messages from Splunk in the GUI, but I saw a JSON parsing error in the _internal index (01-20-2020 16:59:43.458 +0100 ERROR JsonLineBreaker - JSON StreamId:0 had parsing error:Unexpected character while looking for value: 'N'...). But, when I remove the metrics part from the config and index the file to a normal index, I can see the data. Any clues? I tried to follow the guidelines at https://docs.splunk.com/Documentation/Splunk/8.0.0/Metrics/L2MSplunkWeb. My Splunk version is 8.0.1 and I'm doing all this on a single machine. Thanks.
