71 Mail SMTP Service

The Mail SMTP Service monitors the availability, performance and usage of the SMTP functionality provided by the underlying Mail system.

71.1 Bytes Transferred

The Bytes Transferred category provides information about the data transferred between SMTP Server and SMTP Clients.

71.1.1 Bytes Transmitted

This metric measures the amount of data sent to clients by the SMTP Server. The data includes mail and SMTP responses. This value is the sum of all the data sent by the SMTP Redundancy Groups.

Metric Summary

The following table shows how often the metric's value is collected.

Target Version	Evaluation and Collection Frequency
Version 1.0	Every 15 minutes

71.2 Client Connections

The Client Connections category provides information about the client connections on the SMTP Server.

71.2.1 Current Client Connections

This metric shows the number of client connections currently open on the SMTP Server. The value is the sum of all currently open connections for SMTP Redundancy Groups.

Metric Summary

The following table shows how often the metric's value is collected.

Target Version	Evaluation and Collection Frequency
Version 1.0	Every 15 minutes

71.3 Messages

The Messages category provides information about the messages sent and received by the SMTP Server.

71.3.1 Total number of messages received

This metric measures the number of messages received by the SMTP Server from the SMTP Clients. It includes data related to normal SMTP commands and data due to messages appended back to the server, typically to the "Sent" or "Sent Items" folder. This value is the sum of all the messages received by the SMTP Redundancy Groups.

Metric Summary

The following table shows how often the metric's value is collected.

Target Version	Evaluation and Collection Frequency
Version 1.0	Every 15 minutes

71.3.2 Total number of messages transmitted

This metric measures the number of messages sent to SMTP clients by the SMTP Server. The data includes mail and SMTP responses. This value is the sum of all the data sent by the SMTP Redundancy Groups.

Metric Summary

The following table shows how often the metric's value is collected.

Target Version	Evaluation and Collection Frequency
Version 1.0	Every 15 minutes

71.4 Response

The Response category captures the response characteristics of the Mail SMTP Service as seen by a client application.

71.4.1 Status

This metric indicates whether or not the clients can access emails through the SMTP Service. The availability of SMTP Service depends upon the status determined by the Beacon monitoring this service.

User Action

If the Status of Mail SMTP Service is down, then check the results obtained by Root Cause Analysis on the Mail SMTP Service Home Page.

71.5 Response Time

The Response Time category provides information about the average time taken to connect and send emails from the SMTP Server.

71.5.1 Avg. Connect Time (ms)

This metric shows the average time taken for the SMTP server to accept a network connection from a client. This metric also indicates the performance of the Oracle Net Services Listener. The average connection time is the value determined by the Beacon(s) monitoring this service. The Beacon(s) is(are) responsible for executing the perl script to ping the host and determine the average connection time. If multiple Beacons are monitoring this service, the value displayed is the average of all the values determined by all the Beacons.

Metric Summary

The following table shows how often the metric's value is collected.

Target Version	Evaluation and Collection Frequency
Version 1.0	Every 15 minutes

71.5.2 Avg. Send Email Time (ms)

This metric shows the average time taken to transmit an email from the Oracle Collaboration Suite Database (mailstore) through the SMTP server. This metric also indicates database performance. The average time is the value determined by the Beacon(s) monitoring this service. The Beacon(s) is(are) responsible for executing the perl script to ping the host and determine the average email transmission time. If multiple Beacons are monitoring this service, the value displayed is the average of all the values determined by all the Beacons.

Metric Summary

The following table shows how often the metric's value is collected.

Target Version	Evaluation and Collection Frequency
Version 1.0	Every 15 minutes

71.6 SMTP Response

The SMTP Response category captures the response characteristics of the Oracle Mail SMTP service as seen by a client application.

Note:

For target version 1.0, the collection frequency for each metric is every 15 minutes.

The following table lists the metrics and their descriptions.

Table 71-1 SMTP Response Metrics

Metric	Description
[SMTP] Connect Time (ms)	Shows the time taken for the SMTP server to accept a network connection from a client. It is also indicative of the performance of the Oracle Net Services Listener. The connection time is the value determined by the Beacon(s) monitoring this service. The Beacon(s) is(are) responsible for executing the perl script to ping the host and determine the total connection time. If multiple Beacons are monitoring this service, the value displayed is the average of all the values determined by all the Beacons.
[SMTP] Status	Indicates whether or not clients are able to access emails through the SMTP Service. The availability depends upon the status determined by the Beacon monitoring this service.
[SMTP] Status Message	Describes the status. If the Mail SMTP Service is down, this metric shows why the service is down. Its status depends upon the value determined by the Beacon monitoring this service.
[SMTP] Time to Send Email (ms)	Shows the time taken since the last collection of this data for the SMTP server to accept a message for delivery or relay. If the SMTP Servers are not running in 'Submit' mode, this also shows the time it takes for a message to reach the recipient. The time required for Recipient lookup against the Oracle directory server and the time required to store a message in the Oracle Collaboration Suite Database are also factors in the time indicated by this metric. This time is the value determined by the Beacon(s) monitoring this service. The Beacon(s) is(are) responsible for executing the perl script to ping the host and determine the total time. If multiple Beacons are monitoring this service, the value displayed is the average of all the values determined by all the Beacons.
[SMTP] Total Time (ms)	Shows the total time taken since the last collection of this data to complete one simulated SMTP session. This metric is directly dependent on the performance characteristics of the SMTP Server target. The total time is the value determined by the Beacon(s) monitoring this service. The Beacon(s) is(are) responsible for executing the perl script to ping the host and determine the total time. If multiple Beacons are monitoring this service, the value displayed is the average of all the values determined by all the Beacons.
