Attribute Name Description
device stats

A vector updated with communication statistics on an ongoing basis. Each element of the vector contains a counter representing the total number of I/O transactions for a specific condition. These values are incremented indefinitely. To count on a timed bases (e.g. daily), an application should copy values into other attributes. Use the following names, defined in gem80.h, as offsets into the vector:

2 WRITE_ERR Transactions failed due to a socket write error.
3 READ_ERR Transactions failed due to a socket read error.
4 TIMEOUT_ERR Transactions failed due to a timeout.
5 NOT_CONNECTED_ERR Transactions failed due to a failed socket connection.
