Caveats and Issues

Known Limits

  • The maximum size of a logfile is 2GB.

  • The maximum number of fields supported is 30.

  • The application only supports plain text log files (8-bit Ascii).

  • The time span of a log file must be less than 292 years.

Known Issues

  • The table control doesn’t always resize columns correctly.

  • Filtering an event view whose table display has been sorted appears to enter

  • a near infinite loop re-sorting the data

  • Graph drawing performance is poor for large datasets

  • Clicking in the event views does not always cause the session navigator to select the corresponding event, causing the two views to be out of sync.

  • There is no documentation on events; UI pictures are out of date.

  • When setting a marker to hilite the location of an event, the system assumes that the date/time field name contains the text “date”.

  • Where several lines have the same timecode; the global marker is set to the first such line, but the screen scrolls to the last. This is confusing when the two aren’t visible at the same time.

  • Leading irregular lines in the log are not displayed.

  • Only one instance of NLV can run at a time on a system.

  • There is no regression testing.
