Runtime Troubleshooting

This list describes some of the problems you might encounter.

Objects Have Long Cryptic Strings

Problem: When you view the Linux Agent in the console, you might see objects with long cryptic strings, such as ca.halycon. primealert.modules.LinuxSystemAlert.LinuxSystemAlert:moduleName.

The server component of the Linux Agent is not installed on the Sun Management Center server host.

Workaround: Install the server component of the Linux Agent. See Chapter 1, Installing the Linux Agent.

Error Message: Unable to load module definition

After you select PrimeAlert SystemMonitor for Linux in the Load Module window, the Module Loader dialog box appears empty, and this message appears: Unable to load module definition.

Problem: The server component of PrimeAlert SystemMonitor for Linux is not installed on the server host that the console is connected to.

Workaround: Install the server component of PrimeAlert SystemMonitor for Linux. See Chapter 1, Installing the Linux Agent.

Linux Agent Cannot Be Added to the Domain

Problem: When you try to add a Linux Agent to a Sun Management Center domain, the Linux Agent cannot be added to the Domain.

This error message appears: Error occurred during node create.

Workaround: Follow the procedure for creating a Linux object inTo Create a Linux Object As an SNMP Ping Object.

Cannot Create a Sun Management Center Host Type Object

Problem: You cannot create a Sun Management Center host type object for the Linux Agent in the console topology.

Workaround: This issue has multiple possible causes and solutions:

• Ensure that you are creating an SNMP Ping type object first and then changing that object to a Sun Management Center Host type topology object.

• Ensure that you are logged into the Sun Management Center server layer as a user with sufficient privileges to create a topology object.

• Ensure that you have waited long enough to give the Sun Management Center server and the Linux Agent a chance to authenticate with one another. This period might be longer in a larger environment. Start with 5 minutes, then increase to 15 minutes if all else fails.

• Verify that you can ping the Linux host from the Sun Management Center server layer using both the IP address and the host name.

• Verify that you can ping the Sun Management Center server host from the Linux host using both the IP address and the host name.

• Verify that the host name resolves to the correct IP address on the Sun Management Center server.

• Verify that the IP address that you provided to the Sun Management Center server layer is on the same subnet as the Ethernet card containing the IP address being used by the Linux Agent.

• If the Linux host has multiple NIC cards, ensure that the host name on the Linux host resolves to the IP address for the proper NIC. If that resolution fails, modify the agent subsection of the file /var/opt/PrimeAlert/cfg/domain-config.x on the Linux Agent host:

  agentServer = IP-address

  where IP-address is the IP address of the appropriate NIC.
