  1. Select Statistics > Diameter > Host
  2. Double-click the Diameter Host name shown in the content frame.

The local Diameter Host statistics dialog opens (Figure 103).


Figure 103: Local Diameter Host Statistics

Table 29 describes each statistic.

Table 29: Local Diameter Host (Server) Statistics  
Statistic
Meaning

Total packets the server has received

The total number of packets received.

Total packets server has sent

The total number of packets transmitted.

Time elapsed since server was started

The total server up-time in seconds.

Time elapsed since server was reset

The IMS AAA Server does not support a software reset operation, this value will always be zero.

Server status

The only value supported is:

running- the server is currently running.


Diameter Peer Statistics

Statistics are collected and can be displayed for each Diameter peer.

To view Diameter Peer statistics:

Connection Related Statistics

Connection State

Connection state of the peer's state machine with which the server is communicating.

1=Closed - Connection closed with this peer.

2 =waitConnAck - Waiting for an acknowledgment from this peer.

3=waitICea - Waiting for a Capabilities-Exchange- Answer from this peer.

4=elect - When the peer and the server are trying to bring up the connection simultaneously, an election process begins which determines which socket remains open.

5=waitReturns - Waiting for election returns.

6=r-open - Responder transport connection is used for communication.

7=i-open - Initiator transport connection is used for communication.

8=closing - Actively closing and doing cleanup.

State Duration

Peer state duration, measured in centiseconds.

Failed Connects

If there is no transport connection with a peer, this is the number of times the server attempts to connect to that peer. This value is reset on disconnection.

Watchdog State

1=okay - Indicates the connection is presumed working.

2=suspect - Indicates the connection is possibly congested or down.

3=down - The peer is no longer reachable, causing the transport connection to be shutdown.

4=reopen - Three watchdog messages are exchanged with accepted round trip times, and the connection to the peer is considered stabilized.

Watchdog Timer

The interval between watchdog events.

Transport Failures

Number of unexpected transport failures.

Disconnect Cause

The last cause for a peers disconnection:

rebooting - A scheduled reboot is imminent.

busy - The peer's internal resources are constrained, and it has determined that the transport connection needs to be shutdown.

doNotWantToTalk - The peer has determined that it does not see a need for the transport connection to exist, since it does not expect any messages to be exchanged in the foreseeable future.

electionLost - The peer has determined that it has lost the election process and has therefore disconnected the transport connection.

Disconnect By

Identifies who initiated the disconnect:

host - This server initiated the disconnect.

peer - The peer with which this server was connected initiated the disconnect.
