Hi, Simple question here. I'd wish to exclude some processes, what regex flavour should be used, I get errors when using this: - module: system period: 10s metricsets: - process processes: ['^((?!taskhostw|dllhost|svchost).)\*$'] ---

Hello, Thanks for reaching out. I'd recommend reviewing the following doc on regular expression support in metricbeat.
