2.5.3 Using Messaging Agent Log Files

Error messages and other information about Messaging Agent functioning are written to log files as well as displaying on the Messaging Agent console. Log files can provide a wealth of information for resolving problems with Messaging Agent functioning.

  1. In ConsoleOne, browse to and expand the MessengerService object.

  2. Select the Messenger Server object.

  3. Right-click the Messaging Agent, then click Properties.

  4. Click Agent > Log Settings.

    Messaging Agent Log Settings page

  5. Fill in the following fields:

    Log Level: Controls the amount of information logged by the Messaging Agent. Logged information is displayed in the log message box and written to the Messaging Agent log file during the current agent session. The default is Normal, which displays only the essential information suitable for a smoothly running Messaging Agent. Use Verbose to display the essential information, plus additional information helpful for troubleshooting. Use Diagnostic where very detailed, code-specific information is required.

    Enable disk logging: Select this option so that the information displayed in the message log box at the Messaging Agent console is also saved to disk in log files.

    Log Files Path: Specify the directory where the Messaging Agent stores its log files. On NetWare and Windows, the default location is the logs subdirectory of the Messaging Agent installation directory. On Linux, the default location is /var/opt/novell/log/messenger/ma.

    Typically you find multiple log files in the specified directory. The first four characters represent the date. The next three identify the agent. A three-digit extension allows for multiple log files created on the same day. For example, a log file named 0518nma.001 indicates that it is a Messaging Agent log file, created on May 18. If you restarted the Messaging Agent on the same day, a new log file started, named 0518nma.002.

    Log Maximum Age: Specify how many days to keep Messaging Agent log files on disk. The default is 14 days.

    Log Maximum Size: Specify the maximum amount of disk space for all Messaging Agent log files. When the specified disk space is consumed, the Messaging Agent deletes existing log files, starting with the oldest. The default is 128 MB.

  6. Click OK to save the log file settings.

  7. Stop and then start the Messaging Agent to put the new log settings into effect.

Corresponding Startup Switches: You can also use the /log, /loglevel, /logdays, and /logmax startup switches in the Messaging Agent startup file to configure Messaging Agent log files.

2.5.4 Using GroupWise Monitor

GroupWise Monitor can be configured to monitor the Messaging Agent as well as the GroupWise Agents (Post Office Agent, Message Transfer Agent, Internet Agent, and WebAccess Agent). For background information about GroupWise Monitor, see Monitor in the GroupWise 8 Administration Guide.

  1. Enable the Messaging Agent Web console, as described in Setting Up the Messaging Agent Web Console

  2. At the Windows Monitor Agent console, click Configuration > Add Novell Messenger System.

    Add Novell Messenger dialog box in the GroupWise Monitor Agent

  3. Fill in the following fields:

    Novell Messenger System Object: Browse to and select the MessengerService object.

    User Name: Browse to and select a User object that has sufficient rights to enable the Monitor Agent to access Messenger agent object properties in eDirectory.

    Password: Specify the eDirectory password associated with the selected User object.

  4. Provide the same eDirectory access information as you provided during installation:

    Use Direct Access: Select this option if the Messaging Agent uses direct access to eDirectory.

    • Replica Address: If the Messaging Agent is installed on a Windows server, provide the IP address of a server where the Messaging Agent can access a replica of eDirectory. If the Messaging Agent is installed on a NetWare server, you do not need to specify this information because there is an eDirectory replica on the NetWare server

  5. Click OK to save the information about your Messenger system.

    The Messaging Agent appears in the root agent group, along with the Archive Agent if it is running on the same server. You might want to create an agent group specifically for the Messenger agents. See Creating and Managing Agent Groups in Monitor in the GroupWise 8 Administration Guide.

2.5.5 Using Novell 6.5 Remote Manager

If the Messaging Agent is running on a NetWare 6.5 server, you can use the IP Address Management feature in Novell Remote Manager (NetWare Remote Manager > Manage Server > IP Address Management) to view the IP address and port configuration for the Messaging Agent. This is also true for the Archive Agent running on a NetWare 6.5 server.

You access Novell Remote Manager by entering the following URL in a Web browser:

http://server_address:8008

For example:

http://192.168.0.0:8008

For more information about using Novell Remote Manager, see the NetWare 6.5 documentation.

2.5.6 Using SNMP Monitoring Programs

You can monitor the Messaging Agent from the Management and Monitoring component of Novell ZENworks for Servers, ManageWise, or any other SNMP management and monitoring program. When properly configured, the Messaging Agent sends SNMP traps to network management consoles for display along with other SNMP monitored programs. It also responds to requests for configuration and status information from SNMP management and monitoring programs.

Although the Messaging Agent is SNMP-enabled by default, the server where the Messaging Agent is installed must be properly configured to support SNMP, and the Messaging Agent object in eDirectory must be properly configured as well. To set up SNMP services for your Messenger server, complete the following tasks:

Setting Up SNMP Services for the Messaging Agent

Select the instructions for the platform where the Messaging Agent runs:

Setting Up SNMP Services on a NetWare Server

The Messaging Agent 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 Messaging Agent, Messaging Agent still loads and functions normally, but SNMP support is disabled. The Messaging Agent does not attempt to auto-load snmp.nlm.

  1. Go to the console of the NetWare server where you want to implement SNMP services.

    The server should already have the Messenger agents installed.

  2. Enter the command to load the SNMP NLM:

    Syntax: 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.

    Example: load snmp v control=private monitor=public trap=all

    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 entering the following at the console prompt:

    snmp control= trap=

  3. To automatically load these commands, include them in the autoexec.ncf file.

    For more information about implementing SNMP services, see your NetWare documentation.

  4. Skip to Copying and Compiling the Messaging Agent MIB File.

Setting Up SNMP Services on a Linux Server

The Linux Messaging Agent is compatible with NET-SNMP. An older version of SNMP called UCD-SNMP cannot be used with the Linux Messaging Agent. NET-SNMP comes with the versions of Red Hat Linux supported for Messenger 1.0 for Linux, but it does not come with the supported versions of SUSE Linux. If you are using SUSE Linux, you must update to NET-SNMP in order to use SNMP to monitor the Linux Messaging Agent.

  1. Make sure you are logged in as root.

  2. 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

  3. Locate the snmpd.conf file on your Linux server.

  4. In a text editor, modify the snmpd.conf file:

    1. Add the following line:

      dlmod Nmweb /opt/novell/messenger/lib/libnmsnmp.so.1

    2. Save and exit the snmpd.conf file.

  5. Restart the SNMP daemon (snmpd) to put the changes into effect.

  6. In a text editor, modify the nmsnmp.conf file in the /etc/opt/novell/messenger directory:

    1. Set /daemonPort to a unique port number for the Messaging Agent to listen on; for example, 8305.

    2. If you have not already configured the Messaging Agent Web console, as described in Setting Up the Messaging Agent Web Console, assign an HTTP port for the Messaging Agent.

      You can set the HTTP port in ConsoleOne, using the same steps as for setting up the Web console, or you can set /maPort to a unique port number, such as 8301. If you want to use SNMP with the Archive Agent, you can also provide an HTTP port for it by using /aaPort if you update the nmsnmp.conf file, rather than providing the settings in ConsoleOne.

    3. Save and exit the nmsnmp.conf file.

  7. In ConsoleOne, enable SNMP:

    1. Browse to and right-click the Messenger Server object, then click Properties.

    2. Click Server > General.

    3. Select Enable SNMP.

    4. Click OK to save the setting.

  8. Restart the Messaging Agent.

  9. Skip to Copying and Compiling the Messaging Agent MIB File.

Setting Up SNMP Services on a Windows Server

The SNMP service is usually not included during the initial Windows operating system installation. The SNMP service can be easily added at any time. To add or configure the SNMP service, you must be logged in as a member of the Administrator group.

To add the SNMP service to a Windows 2000 server:

  1. From the Control Panel, double-click Add/Remove Programs.

  2. Click Add/Remove Windows Components.

  3. Select Management and Monitoring Tools.

  4. Click Details, then select Simple Network Management Protocol.

    For more information about configuring the SNMP service, see your Windows 2000 documentation.

The Messenger Installation program includes an option for installing SNMP support. However, if the Windows server where you installed the Messaging Agent did not yet have SNMP set up, that installation option was not available. Now that you have set up SNMP, you can install Messaging Agent SNMP support.

Rerun the Messenger Installation program, using the Install Server option as described in the Novell Messenger 2.2 Installation Guide, noticing that the Install and Configure SNMP for the Messenger Agents option is now available and selected.

Figure 2-13 Server Information Dialog Box With the SNMP Option Selected

When you have finished installing the Messenger Agent, continue with Copying and Compiling the Messaging Agent MIB File.

Copying and Compiling the Messaging Agent MIB File

An SNMP-enabled Messaging Agent 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 Messaging Agent.

Before you can monitor an SNMP-enabled Messaging Agent, you must compile the nmma.mib file by using your SNMP management program. On NetWare and Windows, the Messenger agent MIBs are located in the downloaded Novell Messenger 2.2 image in the \server\snmp directory. On Linux, the Messenger MIBs are located in the /etc/opt/novell/messenger/mibs directory after installation.

  1. Copy the nmma.mib file to the location required by your SNMP management program.

    For example, ManageWise users would copy the nmma.mib file to the \mw\nms\snmpmibs\current directory. ZENworks for Servers users can access the nmma.mib file in the downloaded Novell Messenger 2.2 image.

  2. Compile or import the nmma.mib file as required by your SNMP management program.

    For example, to compile the nmma.mib file for ZENworks for Servers:

    1. In ConsoleOne, right-click the Site Server object, then click Properties > MIB Pool.

    2. Click Modify Pool > Add.

    3. Browse to and select the nmma.mib file, then click OK.

    4. Click Compile.

    5. Make sure that the server where the Messaging Agent is running is configured to send SNMP traps to the ZfS Site Server.

      • On a NetWare server, add the IP address or hostname of the ZfS Site Server to the traptarg.cfg file in the sys:\etc directory.

      • On a Windows server, add the IP address or hostname of the ZfS Site Server to the list of trap destinations. From the Windows 2000 Control Panel, double-click Administrative Tools, then click Services > SNMP Service > Properties > Traps.

      Refer to your SNMP management program documentation for specific instructions.

  3. If you are using ManageWise, continue with Customizing Your ManageWise Installation to Monitor the Messaging Agent.

    or

    If you are not using ManageWise, skip to Configuring the Messaging Agent for SNMP Monitoring.

Customizing Your ManageWise Installation to Monitor the Messaging Agent

The downloaded Novell Messenger 2.2 image includes a file that helps ManageWise monitor the Messenger agents more effectively. These capabilities are available only with ManageWise, not with ZENworks for Servers.

The nmma.mib file includes the standard SNMP management information. In addition, the file includes annotations that enhance the Alert functions of ManageWise.

For example, the Summary provides more detailed information than the Description does in other SNMP management programs. The ManageWise annotations are embedded in comments; therefore, they have no affect on other SNMP management programs

When Messaging Agent alarms appear in ManageWise, you can double-click the alarm to display the alarm information contained in the Messenger Alarm help file. To enable this feature, copy the nmalarm.hlp file from the \server\snmp directory in the downloaded Novell Messenger 2.2 image to the \mw\nms\help directory on your ManageWise station. This help file explains the alarms the Messaging Agent might produce by giving a description, cause, and action for each alarm.

Configuring the Messaging Agent for SNMP Monitoring

In order for SNMP monitoring programs to monitor the Messaging Agent, the Messaging Agent must be configured with an SNMP community string.

  1. In ConsoleOne, browse to and expand the MessengerService object.

  2. Right-click the Messenger Server object, then click Properties.

  3. Click Server > General.

    Server General page

  4. Make sure that Enable SNMP is selected.

  5. In the SNMP Community field, provide your system SNMP community GET string.

  6. Click OK to save the SNMP settings.

  7. Stop and then start the Messaging Agent to put the SNMP settings into effect.
