I have created another VBS script, that when run allows the user to select a single IIS log file, it then searches this for Vault Cache download activity and creates a very basic report of the history of VC activity.
The idea is that this allows EV administrators and Support Engineers a better chance of understanding what the Vault Cache status is in the environment.
Where VCstatus is stored on the desktop and test.log is the iis log to analyse
Both scripts need renaming to .vbs and the output is stored in the locale root of C drive.
If you wish to change the default folder output, Please search the vbs file for "outputfile" as this variable controls where the output report is created, be default is it "c:\vcstatus-originalfilename.html"
Please note this is very rough and has only been tested on a handful of IIS logs and environments.
The tools is non destructive to the input files, but use as your own risk :)
Note for the windows 2008 / iis 7 log file the columns in the log file must be formatted like this
'#Fields: date time s-ip cs-method cs-uri-stem cs-uri-query s-port cs-username c-ip cs(User-Agent) sc-status sc-substatus sc-win32-status time-taken
