68 Mail POP Service

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

68.1 Network

The Network category provides information about the data transferred between POP Server and POP Clients.

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 68-1 Network Metrics

Metric	Description
Connectted Clients	Total number of client connections open on the POP Server. The value is the sum of all open connections for the POP Redundancy Groups.
Data Received (kb)	Measures the amount of data received by the POP Server from the POP Clients. It includes data related to normal POP 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 data received by the POP Redundancy Groups.
Data Transmitted (kb)	Measures the amount of data sent to clients by the POP Server. The data includes mail and POP responses. This value is the sum of all the data sent by the POP Redundancy Groups.

68.2 POP Response

The POP Response category captures the response characteristics of the Oracle Mail POP 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 68-2 POP Response Metrics

Metric	Description
[POP] Connect Time (ms)	Shows the time taken for the POP server to accept a network connection from a client. It also reflects 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.
[POP] Login Time (ms)	Shows the time taken for a connected client to log into the POP Server. It is also indicative of the Oracle Internet Directory response time because clients are authenticated against the Oracle directory server. The login 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 login time. If multiple Beacons are monitoring this service, the value displayed is the average of all the values determined by all the Beacons.
[POP] Status	Indicates whether or not clients are able to access emails through the POP Service. The availability depends upon the status determined by the Beacon monitoring this service. If the Status of Mail POP Service is down, then check the results obtained by Root Cause Analysis on the Mail POP Service Home Page.
[POP] Status Message	Describes the status. If the Mail POP Service is down, this metric shows why the service is down. The status depends upon the value determined by the Beacon monitoring this service.
[POP] Time to Read Email (ms)	Shows the time taken to retrieve a message from the Oracle Collaboration Suite Database (mailstore) through the POP server. This metric is also indicative of the database performance. The timing 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.
[POP] Timing (ms)	Shows the total time taken for one simulated POP session. This metric is directly dependent on the performance characteristics of the POP Server target. The timing 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.

68.3 Response

The Status category captures the response characteristics of the Oracle Email POP service as seen by a client application.

68.3.1 Status

This metric indicates whether or not clients are able to access email through the POP Service. The availability of POP Service depends upon the status determined by the Beacon monitoring this service.

User Action

If the Status of Mail POP Service is not up, then check the results obtained by Root Cause Analysis on the Mail POP Service Home Page.

68.4 Response Time

The Response Time category provides information about the average time taken to connect, login, and read the messages from POP Server.

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 68-3 Response Time Metrics

Metric	Description
Avg. Connect Time (ms)	Average time taken for the POP server to accept a network connection from a client. This metric also reflects the performance of the Oracle Net Services Listener.
Avg. Login Time (ms)	Average time taken by a connected client to log into the POP Server. This metric also reflects the Oracle directory server response time, because clients are authenticated against the Oracle directory server.
Avg. Read Email Time (ms)	Average time taken to retrieve a message from the Oracle Collaboration Suite Database (mailstore) through the POP server. This metric also reflects database performance.

68.5 Security

The Security category provides information about security related activities.

68.5.1 Refused Flood Connections

This metric shows the connections refused by the POP Server. The value is the sum of all the connections refused by the POP 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
