Description

RDS-INFO(1)                 General Commands Manual                RDS-INFO(1)



NAME
       rds-info - display information from the RDS kernel module

SYNOPSIS
       rds-info [-cknrstIT]


DESCRIPTION
       The utility presents various sources of information that the RDS kernel
       module maintains.  When run without any optional arguments will  output
       all  the information it knows of.  When options are specified then only
       the information associated with those options is displayed.

       The options are as follows:

OPTIONS
       -v     Requests verbose output. When this option is given, some classes
              of information will display additional data.


       -c     Display  global  counters.  Each counter increments as its event
              occurs.  The counters may not be reset.  The  set  of  supported
              counters may change over time.


       CounterName
              The  name  of the counter.  These names come from the kernel and
              can change depending on the capability of the kernel module.

            Value
              The number of times that the counter has been incremented  since
              the kernel module was loaded.


       -k     Display all the RDS sockets in the system.  There will always be
              one socket listed that is neither bound to nor connected to  any
              addresses  because  itself  uses  an  unbound  socket to collect
              information.


       BoundAddr,
              The IP address and port that the socket is bound to.  0.0.0.0  0
              indicates that the socket has not been bound.

       ConnAddr,
              The  IP  address  and  port  that  the  socket  is connected to.
              0.0.0.0 0 indicates that the socket has not been connected.

       SndBuf,
              The number of bytes of message payload which can be  queued  for
              sending or receiving on the socket, respectively.

       Inode  The  number  of the inode object associated with the socket. Can
              be used to locate the process owning a given socket by searching
              /proc/*/fd  for  open files referencing a socket with this inode
              number.


       -n     Display all RDS connections.   RDS  connections  are  maintained
              between nodes by transports.


       LocalAddr
              The IP address of this node.  For connections that originate and
              terminate on the same node the  local  address  indicates  which
              address initiated the connection establishment.

       RemoteAddr
              The IP address of the remote end of the connection.

       Tos    The type of service value for this connection.

       NextTX The  sequence number that will be given to the next message that
              is sent over the connection.

       NextRX The sequence number that is expected from the  next  message  to
              arrive over the connection.  Any incoming messages with sequence
              numbers less than this will be dropped.

       Flg    Flags which indicate the state of the connection.


                 s
                   A process is currently sending a message down      the con-
              nection.

                 c
                   The  transport  is attempting to connect to the      remote
              address.

                 C
                   The connection to the remote  host  is  connected       and
              active.

                 E
                   The connection to the remote host is in error.


       -r, -s, -t
              Display  the messages in the receive, send, or retransmit queues
              respectively.


       LocalAddr,
              The local IP address and port on this node associated  with  the
              message.  For  sent  messages  this  is  the source address, for
              receive messages it is the destination address.

       RemoteAddr,
              The remote IP address and port associated with the message.  For
              sent  messages this is the destination address, for receive mes-
              sages it is the source address.

       Tos    The type of service for this message.

       Seq    The sequence number of the message.

       Bytes  The number of bytes in the message payload.



       The following information sources are dependent on specific  transports
       which may not always be available.


       -I     Display  the  IB  connections which the IB transport is using to
              provide RDS connections.


       LocalAddr
              The local IP address of this connection.

       RemoteAddr
              The remote IP address of this connection.

       Tos    The type of service value for this connection.

       SL     The QoS Service Level for this connection.

       LocalDev
              The local IB Global Identifier, printed in IPv6 address syntax.

       RemoteDev
              The remote IB Global Identifier, printed in IPv6 address syntax.

              If verbose output is requested, per-connection settings such  as
              the  maximum  number  of  send and receive work requests will be
              displayed in addition.


       -T     Display the TCP sockets which the TCP transport is using to pro-
              vide RDS connections.


       LocalAddr,
              The local IP address and port of this socket.

       RemoteAddr,
              The remote IP address and port that this socket is connected to.

       HdrRemain
              The number of bytes that must be read off the socket to complete
              the next full RDS header.

       DataRemain
              The number of bytes that must be read off the socket to complete
              the data payload of the message which is being received.

       SentNxt
              The  TCP  sequence  number of the first byte of the last message
              that we sent down the connection.

       ExpectedUna
              The TCP sequence number of the byte past the last  byte  of  the
              last message that we sent down the connection.  When we see that
              the remote side has acked up to this byte then we know that  the
              remote side has received all our RDS messages.

       SeenUna
              The TCP sequence number of the byte past the last byte which has
              been acked by the remote host.
