Question
If I use this IF statement,
` if ("FTNTFGTpolicyname" in [message]) or ("FTNTFGTlogid" in [message]) {`, the CPU of the logstash server spikes to very high, pretty much forever.
If I change it to this, CPU is minimal.
`if ([message] =~ "FTNTFGTpolicyname") or ([message] =~ "FTNTFGTlogid") {`
So, what's the difference? Would you expect this difference to make a large CPU difference?
