Clients/Network Panel

The Clients/Network panel displays information about the connections and messages waiting to be sent from your OCS environment. This panel includes:

Secure Connections

Indicates the number of active secure connections (clients) that have been made to this server. Connections are secured using Transport Layer Security (TLS).

Registered Endpoints

Indicates the number of connected endpoints registered.

AD Search Latency (ms)

Indicates the average latency related to queries (in ms) sent to the Active Directory.

Outstanding RPC Calls

Indicates the number of RPC calls waiting to be sent.

Network Output Queue

Indicates the number of network packets waiting to be sent.

Authentication Queue

Indicates the number of authentication requests waiting to be handled.

Theoretical Bandwidth

Indicates the level of network traffic graphed against a "theoretical" maximum bandwidth. The maximum bandwidth is calculated by totaling the capacity of all network devices reported by the operating system. If you are running on an Ethernet network, the actual maximum is approximately 50% of the theoretical bandwidth because of the methods involved in sending data. Having the actual bandwidth equal the theoretical bandwidth is only possible using full duplex Ethernet. Token passing network topologies, such as Token ring and FDDI, enable a theoretical maximum bandwidth much closer to the actual bandwidth.

Ping Time

Indicates the amount of time it takes the computer running the Diagnostic Console to ping the target server.

Server Load Panel

The Server Load panel displays information flow controlled connections, SIP and C3P messages, and database. This panel includes:

Flow Controlled Connections

Indicates the number of connections currently operating in a flow-controlled manner. When a connection is flow-controlled, it can only have one outstanding transaction.

Average Holding Time(s)

Indicates the average time an incoming message waits before being processed.

SIP Messages Outstanding

Indicates the total number of SIP Messages currently being processed by the server.

Message Processing Time(s)

Indicates the average amount of time to process incoming messages.

Conf. Allocation Latency (ms)

Indicates the average time to allocate a new conference.

Outstanding C3P Transactions

Indicates the number of outstanding C3P transactions waiting to be processed.

Database Queue Latency (ms)

Indicates the average amount of time a database request waits in the processing queue for the database to become available.

Database Sproc Latency (ms)

Indicates the average amount of time to execute a stored procedure (Sproc) on the Back-End database.

Server Roles Panel

The Server Roles panel displays information about the amount of CPU being used by your Front-End server and conferencing servers. This panel includes:

Front-End (RTCSrv)

Indicates the amount of CPU usage from the OCS Front-End service.

Front-End (RTCHost)

Indicates the amount of CPU usage from the OCS Front-End host process.

IM Conferencing

Indicates the amount of CPU usage from the OCS IM Conferencing server. It also indicates the number of Allocated Conferences.

PSTN Conferencing

Indicates the amount of CPU usage from the OCS PSTN Conferencing server. It also indicates the number of Allocated Conferences.

Web Conferencing

Indicates the amount of CPU usage from the OCS Web Conferencing server. It also indicates the number of Allocated Conferences.

A/V Conferencing

Indicates the amount of CPU usage from the OCS A/V Conferencing server. It also indicates the number of Allocated Conferences.

OS/Subsystem Panel

The OS/Subsystem panel displays information about the amount of CPU being used by all processes. It also indicates the amount of System Memory and System Disk being used, and reports on any errors. This panel includes:

CPU Usage

Indicates the amount of CPU used by all processes.

Top CPU Consumer

Indicates the top CPU consumer.

Top Memory Consumer

Indicates the top consumer of memory.

System Memory

Indicates the amount of system memory used by all processes.

Processor Queue

Indicates the number of threads waiting to execute.

System Disk

Indicates the amount of system disk space being used.

Event Log Errors

Indicates the number of OCS-related errors in the Event Log.

Last AB Update

Indicates the date stamp of the most recent file in the Address Book share location.
