Hello Brian, want to say "thank you". The regex worked and the explaination helped a lot with following regex. In addition I have to say that I used the prometheus.snmp.exporter implementation in Grafana Alloy agent, first. This implementation has issues with some regex which are working with the snmp_exporter. After using snmp_exporter's debug I could find out which other metrics and regex are wrong and could correct themn.
