Service Element Modules Overview

Service Element modules monitor and measure the availability of services locally. These modules are loaded under Local Applications. They are single-instance modules, except the module that monitors HTTP is multi-instance. You can set alarm thresholds on response times.

These modules send service requests to the services periodically per user configuration settings to determine service availability and local response time.

This following ten Service Element modules are available:

• HTTP: This module determines web server service availability and web page retrieval time using the HTTP protocol on a service site. The module provides process monitoring statistics for the HTTP daemon, as well as monitoring the access log file and reports statistics such as the number of errors. The module also scans the log file that is in common log file format.
• FTP: This module determines the FTP service availability and ability to transfer files to and from the FTP servers on a service site locally. FtpGet gets a file from a server. FtpPut puts a file on the server.
• Telnet: This module determines the availability of the TELNET service locally.
• DNS: This module determines the availability of the DNS Service and the ability of the DNS daemon to resolve a host name. The module measures the server response time locally and provides process monitoring statistics for the DNS daemon.
• NIS: This module determines the NIS service availability and the ability of the NIS daemon to resolve a name in a NIS domain. The supported name resolution types are user name, host name, group name, and mail alias:
• LDAP: This module determines the LDAP service availability and the ability of the LDAP daemon to resolve a name. You can also measure server response time locally.
• SMTP: This module measures the availability of SMTP mail service and server response time locally for sending email. You must create at least one dummy email account on the target server for sending the test email. Remember to periodically delete the test email to ensure that the mailbox does not fill up.
• POP3: This module measures the availability of POP3 mail service and server response time locally while retrieving mail.
• IMAP4: This module measures the availability of IMAP4 mail service and service response time locally for retrieving mail.
• Calendar: This module measures the availability of the Solaris calendar service and ability to retrieve calendar appointments from it. You can also measure the service response time locally.

Using Service Element Modules

Note - The IMAP and POP modules each require a dummy user name and password. The password is passed in clear text during the synthetic transactions and is therefore not secure. Be certain that users for these modules have no privileges.

Before loading a module, you must specify certain configuration parameters. For example, a service port might be requested. For more detail about the confirguration parameters, see Appendix A.

Once a module is loaded, the state of the service is confirmed in the Server Details table. For more information, see Chapter 3.

To Load the Module

1. Load the module.

For detailed information on loading modules, refer to the Sun Management Center 3.0 User's Guide .

2. Enter the required parameters for each module you want to load in the Load Module dialog.

Each module has specific parameters that need to be defined. Once the parameters are completed, the module is loaded in Sun Management Center under the Local Applications category.

3. Go to Local Applications in Sun Management Center agent.

4. Double-click the Service Element module.

To Access the Service Element Modules

1. Click the Browser tab in the Sun Management Center console.

2. Double-click Local Applications to expand this category.

3. Double-click the Service Element if it is loaded. To load it, see To Load the Module.

Once loaded, Service Manager displays the applicable folders.

4. Double-click the applicable folder.

To Activate a Transaction

Refer to Chapter 3, To Activate a Transaction.

To Delete or Edit a Service Element Module
