status vLog VL: Shows the security level of the Graph file (note: If the check-
sum in a logger file or graph file is invalid, vLog will not open the file).
Tampered means at least one logger is a VL-Series logger but one of
the loggers has an invalid checksum.
Secure means each logger is a VL-Series logger and all data and
graphs have valid checksums.
Not Secure means there are security problems, such as one SP-
Series logger shown in the graph, or one of the graphs or logger files
does not have a checksum.
