Pool Nonpaged Bytes: _Total. This counter displays the last observed value only; it is not an
average.
•
Cache Copy Reads/sec—Frequency of reads from pages of the file system cache that involve
a memory copy of the data from the cache to the application's buffer.
•
Cache Copy Read Hits %—Percentage of cache copy read requests that hit the cache, that
is, they did not require a disk read to provide access to the page in the cache. A copy read
is a file read operation that is satisfied by a memory copy from a page in the cache to the
buffer of the application.
Network
TCP
•
Active Connections—Number of times TCP connections have made a direct transition to the
SYN-SENT state from the CLOSED state.
•
Established Connections—Number of TCP connections for which the current state is either
ESTABLISHED or CLOSE-WAIT.
•
Segments/sec—Rate at which TCP segments are sent or received using the TCP protocol.
•
Segments Retransmitted/sec—Rate at which segments are retransmitted, that is, segments
transmitted containing one or more previously transmitted bytes.
•
Connection Failures—Number of times TCP connections have made a direct transition to the
CLOSED state from the SYN-SENT state or the SYN-RCVD state, and the number of times TCP
connections have made a direct transition to the LISTEN state from the SYN-RCVD state.
Controller
•
Total Bytes/sec—Rate at which bytes are sent and received on the interface, including framing
characters.
•
Packets/sec—Rate at which packets are sent and received on the network interface.
•
Output Queue Length—Length of the output packet queue (in packets). If this length is longer
than 2, delays are being experienced and the bottleneck should be found and eliminated if
possible. Since the requests are queued by the Network Driver Interface Specification or NDIS
in this implementation, this length is always set to zero.
•
Packet Outbound Errors—Number of outbound packets that could not be transmitted because
of errors.
•
Packet Receive Errors—Number of inbound packets that contained errors preventing them
from being deliverable to a higher-layer protocol.
•
Current Bandwidth (Mbits/sec)—Estimate of the current bandwidth of the interface in megabits
per second. For interfaces that do not vary in bandwidth or for those where no accurate
estimation can be made, this value is the nominal bandwidth.
•
Bytes Sent/sec—Rate at which bytes are sent on the interface, including framing characters.
•
Bytes Received/sec—Rate at which bytes are received on the interface, including framing
characters.
•
Packets Sent/sec—Rate at which packets are sent on the network interface.
•
Packets Received/sec—Rate at which packets are received on the network interface.
