I imagine by now you have figured this out, but in case not, and in case it's helpful for anyone else, the logparser query you posted looks like this:
SELECT TO_UPPERCASE(EXTRACT_TOKEN(EXTRACT_TOKEN(Strings,2,','),0,'.')) as cn, MAX(EXTRACT_TOKEN(Strings,4,',')) as date INTO 'c:\inetpub\wwwroot\your_path_here\your_page_here.html' FROM '\\your_KMSserver_here\Key Management Service' WHERE EXTRACT_TOKEN(Strings,6,',') LIKE '1' GROUP BY cn ORDER by cn ASC
...just ditch the "where" portion to get all the systems:
SELECT TO_UPPERCASE(EXTRACT_TOKEN(EXTRACT_TOKEN(Strings,2,','),0,'.')) as cn, MAX(EXTRACT_TOKEN(Strings,4,',')) as date INTO 'c:\inetpub\wwwroot\your_path_here\your_page_here.html' FROM '\\your_KMSserver_here\Key Management Service' GROUP BY cn ORDER by cn ASC
