I'm trying to find LONG UserAgent strings with LogParser.exe in my IIS logs. This example searches for entries with the string 'poo' in them.
LogParser.exe -i:IISW3C
"SELECT COUNT(cs(User-Agent)) AS Client
FROM *.log WHERE cs(User-Agent) LIKE '%poo%'"
I'm trying to say "How many entries have a User-Agent that is longer than 'x'".
