I need to index the logs for a web service. For each end-user's interactions with the system, a collection of web service calls are likely to be made. In the raw files, each is a separate line, and different sessions will be woven in together, because it is a multi-user system. The one thing they will all have in common is the session ID. For example: 13:28:09,080 01/31 0317BF7117D4C4A2F80CE25BB76F8EB8 ... ConfigurationService.lookupApplicationConfigurationProperties ... 13:28:09,086 01/31 D4CC24E705670088920490171F76A079 ... NetworkService.queryOutages ... 13:28:09,234 01/31 0317BF7117D4C4A2F80CE25BB76F8EB8 ... ConfigurationService.uivrLookupBroadcastMessages ... 13:28:09,298 01/31 D4CC24E705670088920490171F76A079 ... AppointmentService.queryAppointment ... 13:28:09,385 01/31 B5D41CFAE762291AEDD43CE424B751F8 ... IdentifyService.dtmfLookupCustomerByTN ... What I need to do is select across multiple rows. In the above example, where the session ID starts with 0317, those lines are for one customer. I need to be able to compose a search that will treat all of those lines as being together, so I can specify criteria across different services. A single customer session may be composed of 10 services, and I need to select all of the customer sessions that included services X, Y, and Z, and for each of those services, I want to put restrictions in there, such as field X.FOO=someValue, Y.BAR=somethingElse, and Z.BLIP=argh Is this even doable?
