You can monitor the MTA from the Management and Monitoring component of Novell ZENworks for Servers or another SNMP management and monitoring program. When properly configured, the MTA sends SNMP traps to network management consoles for display along with other SNMP monitored programs.
Although the MTA is SNMP-enabled by default, the server where the MTA is installed must be properly configured to support SNMP, and the MTA object in eDirectory must be properly configured as well. To set up SNMP services for your server, complete the following tasks:
Select the instructions for the platform where the MTA runs:
The NetWare MTA supports SNMP through the SNMP services loaded on the NetWare server. SNMP services are provided through the SNMP NLM. The SNMP NLM initiates and responds to requests for monitoring information and generates trap messages.
If the SNMP NLM is not loaded before the NetWare MTA, the MTA still loads and functions normally, but SNMP support is disabled. The MTA does not attempt to auto-load snmp.nlm.
To load the SNMP NLM manually:
Go to the console of each NetWare server where you want to implement SNMP services.
These servers should already have the GroupWise agents installed.
Type the command to load the SNMP NLM:
load snmp v control=x monitor=y trap=z
where v represents Verbose, meaning to display informational messages, and x, y and z are replaced with your system SNMP community strings for SNMP SETs, GETs and TRAPs).
load snmp v control=private monitor=public trap=all
The configuration for the SNMP NLM is found in snmp.cfg and traptarg.cfg in the sys:\etc directory. View the contents of these files for more information.
The TCP/IP NLM automatically loads snmp.nlm, using default values for the community strings. If your system uses different community string values, load snmp.nlm before tcpip.nlm.
If the SNMP NLM is already loaded, you can add the control and trap parameters by typing the following at the console prompt:
snmp control= trap=
To automatically load these commands, include them in the autoexec.ncf file.
For more information about implementing SNMP services, see your NetWare documentation.
The Linux MTA is compatible with NET-SNMP. An older version of SNMP called UCD-SNMP cannot be used with the Linux MTA. NET-SNMP comes standard with OES Linux, but it does not come standard with SLES 9. If you are using SLES 9, you must update to NET-SNMP in order to use SNMP to monitor the Linux MTA.
Make sure you are logged in as root.
If NET-SNMP is not already set up on your Linux server, use the following command to configure SNMP:
snmpconf -g basic_setup
The snmpconf command creates the snmpd.conf file in one of the following directories, depending on your version of Linux:
/usr/share/snmp /usr/local/share/snmp ~/.snmp
Locate the snmpd.conf file on your Linux server.
In a text editor, open the snmpd.conf file and add the following line:
dlmod Gwsnmp /opt/novell/groupwise/agents/lib/libgwsnmp.so
Save the snmpd.conf file and exit the text editor.
Restart the SNMP daemon (snmpd) to put the changes into effect.
IMPORTANT:Make sure that the SNMP daemon always starts before the MTA starts.
SNMP support is provided for up to eight Windows MTAs on the same Windows server. Upon startup, each instance of the MTA is dynamically assigned a row in its SNMP table. View the contents of the MTA MIB for a description of the SNMP variables in the table.
To set up SNMP services for the Windows MTA, complete the following tasks:
For Windows, the SNMP Trap Service is usually not included during the initial operating system installation. The SNMP Trap Service can be easily added at any time. To add or configure the SNMP Trap Service, you must be logged in as a member of the Administrator group.
For example, to add the SNMP Trap Service to Windows Server 2003:
Click, then select .
Follow the on-screen instructions to install the SNMP Trap Service.
Continue with Installing GroupWise Agent SNMP Support.
The GroupWise Agent Installation program includes an option for installing SNMP support. However, if the server where you installed the agents did not yet have SNMP set up, that installation option was not available. Now that you have set up SNMP, you can install GroupWise agent SNMP support.
At the Windows server where you want to install the GroupWise agent SNMP support:
Run setup.exe at the root of the GroupWise 8 DVD or downloaded GroupWise 8 software image, then click .
Run install.exe from the agents subdirectory on the GroupWise 8 DVD or downloaded GroupWise 8 software image, or in your software distribution directory if you have updated it with the latest GroupWise software.
In the Installation Path dialog box, browse to and select the path where the agent software is installed, then select.
To shorten the install time, deselect
Continue through the rest of the installation process as prompted by the Agent Installation program.
The Agent Installation program copies the SNMP support files to the agent installation directory, makes the appropriate Windows registry entries, and restarts the Windows SNMP service.
Continue with Section 42.6.2, Copying and Compiling the MTA MIB File.
An SNMP-enabled MTA returns information contained in a Management Information Base (MIB). The MIB is an ASCII data structure that defines the information gathered. It also defines the properties that can be monitored and managed on the SNMP-enabled MTA.
Before you can monitor an SNMP-enabled MTA, you must compile the gwmta.mib file using your SNMP management program.
NetWare and Windows:
The GroupWise MIBs are located on the GroupWise 8 DVD or downloaded GroupWise 8 software image in the \agents\snmp directory or in the software_distribution_directory\agents\snmp directory if you have updated it with the latest GroupWise software.
The GroupWise MIBs must be obtained from a NetWare or Windows installation.
Copy the gwmta.mib file from the \agents\snmp directory to the location required by your SNMP management program.
ZENworks Server Management users can access the gwmta.mib file in the software distribution directory.
Compile or import the gwmta.mib file as required by your SNMP management program.
For example, to compile the gwmta.mib file for ZENworks Server Management:
In ConsoleOne, right-click the Site Server object, then click.
Browse to and select the gwmta.mib file, then click .
Make sure that the server where the MTA is running is configured to send SNMP traps to the ZENworks Server Management Site Server.
Add the IP address or hostname of the ZENworks Server Management Site Server to the traptarg.cfg file in the sys:\etc directory.
Add the IP address or hostname of the ZENworks Server Management Site Server to the list of trap destinations. For example, in Windows Server 2003, click. Right-click , then click . On the tab, add the IP address or hostname of the ZENworks Server Management Site Server.
Refer to your SNMP management program documentation for further instructions.
Continue with Configuring the MTA for SNMP Monitoring.
In order for SNMP monitoring programs to monitor the MTA, the MTA must be configured with a network address and SNMP community string.
In ConsoleOne, browse to and right-click the MTA object, then click.
Clickto display the Network Address page.
Click the pencil icon to provide the TCP/IP address or IPX/SPX address of the server where the MTA runs, then click.
Provide your system SNMP community GET string, then click.
ConsoleOne then notifies the POA to restart so the new settings can be put into effect.
The MTA should now be visible to your SNMP monitoring program.
