Item

Description

table rows

Each row of the table describes one network service—that is, a UDP service on a particular network interface.

Service

The UDP service number.

Clicking this number displays the Service Information page.

Network

The network number or multicast specification.

Hosts

The number of other host computers with Rendezvous daemons that communicate on this network and service.

Clients

The number of client transports that use this network and service.

Service Information

Item

Description

Service

The UDP service number.

Network

The network number or multicast specification.

Reliability

On this service, rvd retains outbound message data for retransmission. After this interval, it discards the data. For complete details, see Reliability and Message Retention Time.

Creation

Date and time that this service became active.

Clients

The number of client transports that use this network service. To view the Clients page, click this item.

Hosts

The number of other host computers with Rendezvous daemons that communicate on this network and service. To view the Host List page, click this item.

Subscriptions

The number of subscriptions registered with the daemon on this network service. To view the list of subscriptions, click this item.

Communication ID

Identifies the daemon and service. TIBCO support staff may request this value for diagnostic purposes.

Inbound Rates

The rate (per second) at which inbound messages, bytes and packets arrived on this network service during the most recent sampling period.

Outbound Rates

The rate (per second) at which the daemon sent outbound messages, bytes and packets on this network service during the most recent sampling period.

Inbound Counts

Cumulative statistics about inbound data messages; running totals since the start of the daemon process:

• msgs—number of messages
• bytes—number of bytes

Outbound Counts

Cumulative statistics about outbound data messages; running totals since the start of the daemon process:

• msgs—number of messages
• bytes—number of bytes

Inbound Packet Totals

Cumulative statistics about inbound packets; running totals since the start of the daemon process:

• pkts—number of data packets
• missed—number of missed packets (detected as a packet sequence gap)
• lost MC—number of multicast packets lost because the sending daemon could not retransmit them
• lost PTP—number of point-to-point packets lost because the sending daemon could not retransmit them
• suppressed MC—number of multicast packets for which the daemon suppressed the sending of retransmission requests (see Retransmission Control )
• bad pkts—number of unreadable data packets

These bad packets correspond to DATALOSS advisories in which the error description string includes the words multicast destination. For information about non-zero values see .

Outbound Packet Totals

Cumulative statistics about outbound packets; running totals since the start of the daemon process:

• pkts—number of data packets
• retrans—number of packets retransmitted (multicast and point-to-point)
• lost MC—number of multicast packets the daemon could not retransmit (too old)
• lost PTP—number of point-to-point packets the daemon could not retransmit (too old)
• shed MC—number of multicast packets for which the daemon ignored retransmission requests from a chronically-lossy receiver, and did not retransmit the data (see Retransmission Control )
• bad retreqs—number of unreadable retransmission request packets

These bad packets correspond to DATALOSS advisories in which the error description string includes the words multicast destination. For information about non-zero values see .
