Installation Guide

♦FIle Sysytem monitoring cannot be inherited on the system using
EXPRESSCLUSTER
When using NEC ESMPRO Agent in the cluster environment configured by EXPRESSCLUSTER, there is a following
limitation:
- If a failover occurs, the settings of the threshold for the empty space monitoring function and the enable/disable of
monitoring of the operating sever are not inherited to the standby server. Make sure to reset the threshold and the
enable/disable of monitoring on the standby server.
♦Using with Oracle Products
When an Oracle product is installed, the startup of SNMP Service may be changed to "Manual". In such a case, restore
it to "Automatic" and configure the appropriate settings according to the instructions of the Oracle product. For any
concerns, contact "NEC Oracle Response Center".
♦Microsoft Failover Cluster (MSFC)*
When MSFC is used, the following event may be registered and reported to NEC ESMPRO Manager.
Source : AlertManagerMainService
Event ID : 802
Description : The past event was detected during the System log monitoring.
The possible causes are as follows:
- The system time has been changed.
- Shutdown was not performed properly.
- The event log file is corrupted.
Although MSFC has a feature that all the events of clustered computers are visible, the events may not be stored to the
event log in the order of date (such as when either of the computers was shut down or started).
NEC ESMPRO Agent checks whether the events are stored in the order of date. Therefore, when an event not in the
order of date is found, it registers such an event assuming that "the past event is detected".
Even when the event is registered due to this feature of MSFC, the event log monitoring feature
continues and it operates properly for those events in the order of date.
* On Windows Server 2008, the name of MSFC was changed to Microsoft Cluster Service (MSCS).
