COUNTER DESCRIPTION LOCAL QUEUE INDICATES THE NUMBER OF MESSAGES...

2000.

Counter Description

Local Queue

Indicates the number of messages in the local queue. A normal

Length

reading is 0. If the reading is greater than 0, the server is

receiving more messages than it can process. If the number

steadily increases, you need to determine what is causing the

delay in processing.

Displays the number of messages waiting for advanced address

Categorizer

resolution to occur before the message is placed in the local

Queue Length

queue or sent to the routing engine for delivery. A high number

can indicate a message flow problem within your intranet.

Inbound

Measures the number of connections that are currently inbound.

Connections

A reading of 0 for an extended time can indicate network

Current

problems.

Measures the rate at which inbound messages are being received.

Message Bytes

Received/sec

Use this counter to determine healthy output compared to your

baseline.

Measures the rate that bytes are being sent in messages. Use this

Sent/sec

counter to determine healthy output compared to your baseline.

Monitoring MTA Performance

If the computer running Exchange 2000 supports inbound or outbound

messages from X.400 recipients, monitor the MSExchangeMTA and

MSExchangeMTA Connections objects and their related counters.

MSExchangeMTA

For the MSExchangeMTA object, monitor the following counters:

Messages/Sec Measures the number of messages that the MTA sends and

receives each second. The Messages/Sec counter is a helpful

method to quickly measure traffic sent to other servers.

Work Queue

Monitors the number of messages queued in the MTA for

delivery to other servers and the number of messages in the

receiving queue. The Work Queue Length counter divided by

Messages/Sec provides an estimate of how long messages are

delayed in this queue before they are delivered or sent. A high

number resulting from this calculation indicates a problem, either

in performance or in transmitting messages to other servers.

MSExchangeMTA Connections

For the MSExchangeMTA Connections object, monitor the following

counter:

Queue Length Displays MTA counters on a connection-by-connection basis.

Queue Length looks at this queue from one MTA to any other

specific MTA. If the MTA Work Queue Size Length is large,

the Queue Length counter shows which connections are

responsible for the large queue.
