@bbigras Really weird. Could you try adding a log statement which outputs the query to collector/process.go? Basically add log.Println(q) here: https://github.com/martinlindhe/wmi_exporter/blob/94caf8ee61027bd02ae694353597741182b00829/collector/process.go#L183-L187

@martinlindhe You only get one firefox process due to matching exactly on 'firefox'. WMI separates multiple instances of the same name by adding a number after the name, so you get firefox.exe, firefox.exe#1 and firefox.exe#2. These suffixes are handled here, if present: https://github.com/martinlindhe/wmi_exporter/blob/94caf8ee61027bd02ae694353597741182b00829/collector/process.go#L194-L195

To get all the processes, you need to change the where-clause to Name LIKE 'firefox%', though. I thought this was documented somewhere, but I don’t see it now…
