Why doesn't my flight show up? What types of flights are tracked?

Both VFR and IFR flights are tracked, as long as they file a flightplan. Flights must either have not departed, be CURRENTLY airborne, or have arrived to be listed. This means that flights that you do not complete (land) will be purged a short time after you disconnect.

If you disconnect mid-flight and then resume it later, vataware may discard your "first connection" data. To avoid this, don't disconnect mid-flight. Pausing for long periods of time can also confuse vataware and cause various problems, so don't do that either - pausing on VATSIM is generally a bad idea anyway.

vataware also will lose flights when the arrival airport is not in the database, because it can't tell that you ever arrived! See the https://vataware.tenderapp.com/help/kb/general-questions/why-do-som... to submit the airport, in that case!
