Measure Reference Manual

DOUT4-BYTES
Number of Level 4 data bytes written by the network line handler. This counter includes only user
data and, on D-series, message system protocol bytes. The data associated with line protocol is
ignored.
In G-series and earlier RVUs, this is a 32-bit counter. In H-series and J-series RVUs, this is a 64-bit
counter.
In G-series RVUs, the DOUT4-BYTES-F field is a 64-bit version of DOUT4-BYTES.
Counter type: Accumulating.
L2IN-BYTES
Number of Level 2 bytes read by the network line handler. This counter includes both user data
and data associated with line protocol.
For non-CSS type controllers, this counter contains DIN4-BYTES and CIN4-BYTES. For CSS type
controllers, this counter also contains CLB (CAP to CLIP) protocol and CLIP TRACE blocks.
The total number of Level 2 bytes on the network line is this counter plus L2OUT-BYTES.
In G-series and earlier RVUs, this is a 32-bit counter. In H-series and J-series RVUs, this is a 64-bit
counter.
In G-series RVUs, the L2IN-BYTES-F field is a 64-bit version of L2IN-BYTES.
Counter type: Accumulating.
L2OUT-BYTES
Number of Level 2 bytes written by the network line handler. This counter includes both user data
and data associated with line protocol.
For non-CSS type controllers, this counter contains DOUT4-BYTES and COUT4-BYTES. For CSS
type controllers, this counter also contains CLB protocol bytes.
The total number of Level 2 bytes on the network line is this counter plus L2IN-BYTES.
In G-series and earlier RVUs, this is a 32-bit counter. In H-series and J-series RVUs, this is a 64-bit
counter.
In G-series RVUs, the L2OUT-BYTES-F field is a 64-bit version of L2OUT-BYTES.
Counter type: Accumulating.
O4095-BYTES
Number of messages longer than 4095 bytes long after compression. The size includes protocol
bytes.
Counter type: Incrementing.
READ-BUSY-TIME
Time spent reading data from the network communications line. This counter includes the time spent
waiting for input to the line. The counter measures the time from the instruction that starts the read
to the interrupt that signals the end of the I/O operation.
Because active, full-duplex lines usually have a read continue outstanding, expect a high value for
this counter. Any process can run during this time.
This counter is only measured when Expand over SWAN is in use.
Counter type: Busy.
READS
Number of read operations (from the network communications line to memory) performed by the
line-handler process.
