Purpose
Displays information from the kernel
extension of the Reliable Datagram Sockets (RDS) .
Syntax
rds-info [-v ] [ -cknrst]
Description
The rds-info utility
displays various sources of information that the RDS kernel module
maintains. When you run the rds-info utility without
any optional arguments, the output has all the information. When you
specify the optional arguments, the information that is associated
with those options is displayed.
Parameters
| Item |
Descriptor |
-c |
Displays global counters. Each counter increments
after the event occurs. You cannot reset the counters. The set of
the supported counters can change with time. The list of output fields
includes:
- CounterName
- The name of the counter. These names are derived from the kernel
and can change based on the capability of the kernel extension.
- Value
- The number of times the counter increments after the kernel module
is loaded.
|
-k |
Displays all the RDS sockets in the system.
There is one socket that is listed at a time that is not bound to
or connected to any address because the rds-info utility
uses an unbound socket to collect information. The list of output
fields includes:
- BoundAddr, BPort
- The IP address and port number to which the socket is bound. The
0.0.0.0 0 address indicates that the socket is not bound.
- ConnAddr, CPort
- The IP address and port number to which the socket is connected.
The 0.0.0.0 0 address indicates that the socket is not connected.
- SndBuf, RcvBuf
- The message payload in bytes that can be queued for sending or
receiving on the respective socket.
|
-n |
Displays all the RDS connections. RDS connections
are maintained between nodes by the network transports. The list
of output fields includes:
- LocalAddr
- The IP address of a node. For connections that originate and terminate
on the same node, the local address indicates the address that initiated
the connection establishment and
- RemoteAddr
- The IP address of the remote end of the connection.
- NextTX
- The sequence number that is given to the next message that is
sent over the connection.
- NextRX
- The expected sequence number of the next message that arrives
over the connection. Any incoming messages with sequence numbers less
than the expected number is dropped.
- Flg
- Flags that indicate the state of the connection.
- s
- A process is sending a message down the connection.
- c
- The transport is attempting to connect to the remote address.
- C
- The connection to the remote host is active.
|
-r, -s, -t |
Displays the messages in the receive, send,
or retransmit queues.
- LocalAddr, LPort
- The local IP address and port number of the node that is associated
with the message. For sent messages, this address is the source address.
For receive messages, this address is the destination address.
- RemoteAddr, RPort
- The remote IP address and port number that is associated with
the message. For sent messages, this address is the destination address.
For receive messages, this address is the source address.
- Seq
- The sequence number of the message.
- Bytes
- The message payload in bytes.
|
-v |
Displays verbose output. When this option is
specified complete data is displayed. |
