What’s in this Version What’s in this Version Version A.01.00 is the first release of the EMS HA Monitors product. Benefits The EMS HA Monitors product enhances your high availability environment: • EMS monitors make is easier to monitor many systems with little or no human intervention except to fix problems. EMS monitors system resources, such as disks, file systems, and network interfaces and sends events when these resources reach user-defined critical levels.
What’s in this Version • The network monitor reports the status of LAN interfaces. • The system resource monitor checks the status of users, system load, and file system space. • The EMS graphical interface runs under SAM and allows you to create, modify, and remove monitoring requests. It also displays all current requests. • The framework interprets requests to monitor resources and sends events to system management software using the available protocols.
Known Problems and Workarounds Known Problems and Workarounds The following are known problems with the EMS HA Monitors product: • EMS may not function if you are running name services that do not use /etc/services, such as NIS, DNS, or X.500. The port number for the EMS registrar is listed in /etc/services.
Known Problems and Workarounds • The network monitor may report invalid status for LAN interfaces. The EMS monitor gets LAN interface status from the MIB-II subagent. Certain Ethernet LAN drivers have problems reporting correct values to the MIB-II subagent causing the monitor to report an Ethernet LAN card as DOWN when it is functioning properly. The affected LAN card is Hewlett-Packard LAN Interface Hw Rev 0 (P/N 25567B).
