♦ About Applications run on the Management PC
[About the NEC ESMPRO User Group] To use applications run on the management PC, let the user belong as a member of the NEC ESMPRO User Group (by default, Administrators).
[About coexistence of NEC ESMPRO Manager with other vendor's SNMP management application] When another vendor's SNMP management application which receives an SNMP trap is used along with NEC ESMPRO Manager, one of them may fail to receive the SNMP trap due to a conflict between the two applications. Through the following procedures, the situation can be avoided. [Work Around 1] If the other vendor's SNMP management application supports the trap reception function of standard SNMP Trap Service, you can change the setting of NEC ESMPRO Manager according to the instruction below. Select [Options] – [Customize] – [My Manager] on the Operation Window, and change the Method of receiving an SNMP Trap to "Use SNMP Trap Service".
| The SNMP Trap Service is installed together with the SNMP Service. However, it does not start by default. Start [Services] from [Control Panel] to start up the SNMP Trap Service (It is useful that you set [Automatic] for [Startup type].).
Note that if you set to use SNMP Trap Service, the name of the NetWare server (host) that sent a trap via the IPX protocol cannot be identified. [Work Around 2] By utilizing the "TCP/IP report to Manager" function of NEC ESMPRO Agent, the alert reception function of NEC ESMPRO Manager operates normally.
| TCP/IP report to Manager | : | Transfers an alert from a server to the NEC ESMPRO Manager using an original protocol.
Note that the operability of the SNMP Trap reception function on the other vendor's SNMP management application cannot be guaranteed.
[About transfer of DMI events on Inter-Manager Communication] DMI events are not transferred between the Inter-Manager Communication.
[Installing other DMI management application and manager on the same machine] In case when other DMI management application is installed to the same machine, receiving DMI events with AlertViewer may not work properly. Be sure not to install NEC ESMPRO Manager and DMI management application on the same machine.
[About monitoring Ver. 3.2 or prior version of NEC ESMPRO Agent and DMI Agents] A function for monitoring Ver.3.2 or prior version of NEC ESMPRO Agent and DMI Agents has been removed from the NEC ESMPRO Manager Ver. 4.3 or later. As a result, the Manager behaves as follows.
• | By performing auto-discovery, server icons are registered on the Operation Window.
• | SNMP traps and DMI events sent from monitored servers are displayed on the AlertViewer properly.
• | If the "Watch Server Status" properties are "On" for Ver. 3.0 or prior version of NEC ESMPRO Agent, the status color is displayed in gray (unknown). Set "Off" for the "Watch Server Status" properties or delete the icon of the Agent.
• | Status of DMI Agents is not monitored through DMI even if the "Watch Server Status" properties are "On".
• | The information of Ver.3.0 or prior version of NEC ESMPRO Agent and the DMI Agents is not viewed on the DataViewer or the GraphViewer, and not collected by the Automatic Data Collection function.
• | Monitoring storages for NEC ESMPRO Agent Ver. 3.0 to Ver. 3.1 is not supported.
[Receiving DMI events from the machine belonging to multiple networks] Receiving DMI events from the machine (with multiple IP addresses) belonging to multiple networks may not be available.
[About using NEC ESMPRO Manager on a machine with a high load]
• | When a machine on which the NEC ESMPRO Manager is installed is under high load: If you use the machine with an extremely high load such as when 100% of the CPU has been used for a long time period, the message "Communication with NVBase System Service became invalid" may appear. Manager applications communicate with a service (NVBase System Service). The above message appears when the communication is timed-out due to high load. If this message appears, decrease the load on the machine and restart the application.
• | When a machine on which the NEC ESMPRO Agent is installed is under high load: If a machine on which the NEC ESMPRO Agent is installed is operating with a high load, NEC ESMPRO Agent does not respond to the query from the NEC ESMPRO Manager. Therefore, the following problems may occur:
– | The icon for the machine is grayed out on the Operation Window.
– | The following error messages are displayed when the DataViewer is started.
Could not collect information on the host. Please refer to Recovery Action for errors in DataViewer Help.
– | The machine information becomes "Unknown" on the DataViewer.
– | The following message is registered in the AlertViewer when the "Detect Server Down" property is "On".
Summary | :
| No response from the server.
Detail | : | Alert generation time ... The server doesn't respond to SNMP access from the Manager. There is the possibility that the server is down, the load on the server has been excessively increased, or the network is not functioning properly.

[About transmitting and receiving packets between
NEC ESMPRO Manager and NEC ESMPRO Agent]

Packets will be transmitted/received between NEC ESMPRO Manager and the Agent at the following times.
We recommend reasonable care in operating in a system which charges you for things such as connection on a WAN.
In addition, note that a large amount of data is flown in server management by DMI (Set "On" for DMI Agent displayed on a server icon on the Operation Window).

* | Server management by DMI is for other vendor's server client on which DMI is installed. You do not need to use DMI for managing machines on which NEC ESMPRO Agent is installed.

• | At autodiscovery of servers on the Operation Window.
• | At a specified interval after specifying regular autodiscovery on the Operation Window.
• | When deleted server where DMI agent is checked for its properties on the Operation Window.
• | When DMI Agent is registered on the Operation Window.
• | When the DMI Agent is turned OFF on the Operation Window.
• | When the DMI Agent is turned ON on the Operation Window.
• | When Remote Wake UP is executed on the Operation Window.
• | Irregularly, after specifying inter-manager communication on the Operation Window.
• | At receiving an SNMP Trap.
• | At receiving DMI event.
• | At startup of the operating system, for all the DMI agents registered at the Operation Window.
• | About every one minute after DataViewer is started.
• | About every one minute after GraphViewer is started.
• | At a specified interval for a specified server, after setting Automatic Data Collection.
• | Regular polling about every one minute to monitor server status.*
* | This can be avoided by turning "Watch Server Status" off at the Properties dialog box on the Operation Window's server icon. However, the server status will not be reflected in the color of the icon on the Operation Window.

[Setting an SNMP trap destination]

When you install NEC ESMPRO Manager and NEC ESMPRO Agent on the same computer, specify the IP address assigned to the network card or the host name as the SNMP trap destination for the computer, instead of the loop back address 127.0.0.1. If you specify 127.0.0.1, "unknown server" may be displayed on the AlertViewer.
On the other hand, you may need to specify 127.0.0.1 for a computer not connected to the network. For more information, see "Settings on Standalone Environments Without Network Connections" below.
If the following is displayed on the AlertViewer even when you have specified as above,

Component | : | {unknown server}
Address | : | 127.0.0.1

change the IP address to 127.0.0.1 on the properties of the server icon on the Operation Window.

[Settings on standalone environments without network connections]

When you install the NEC ESMPRO Manager and the NEC ESMPRO Agent on a machine together, if the machine is not connected to the network, take the following steps to monitor the machine itself:

• | Specify 127.0.0.1 for Start Address and End Address as a range for the Auto-discovering.
• | Specify 127.0.0.1 for the SNMP trap destination.

If you have already registered server icons, execute AutoDiscover after deleting the icons.

[About the threshold dialog box for the temperature sensor]

For some servers, only the Fatal status may be displayed on the dialog box for setting threshold values of the temperature sensor.
In this case, the sliders show yellow (Warning) and red (Fatal), but green is displayed as the actual status color when temperature of a target machine is lower than the specified Fatal limit.

[About versions when using Inter-Manager Communication]

If you use Inter-Manager Communication between different versions of the NEC ESMPRO Manager, the following problems may occur:
– The alerts will not be sent to the neighbor manager.
– Part of the information will not be displayed in the DataViewer.
When you use Inter-Manager Communication, in advance, be sure to use the same version of the NEC ESMPRO Manager by performing an update installation if needed.

[Operations as a user who does not have Administrators privilege]

When you log on as a user who belongs to the NEC ESMPRO User Group but does not have Administrators privilege, there is the following problem (unless you specified the default Administrators as the NEC ESMPRO User Group during installation of NEC ESMPRO Manager):
If you perform a wrong operation by mistake, perform the following measure:
[Problem]

When you select [Tools] – [Report Settings] on the AlertViewer to open the Alert Manager window, select [Setting] – [Base Setting] on that window to open the Receive tab of the Base Setting window and change the setting of Receive from Agent (TCP/IP), the following will occur:

– | When you have changed from Receive valid (green) to Receive invalid (red): Even though the status of each item appears to be changed to "Receive invalid (red)", the service (Alert Manager Socket(R) Service) does not actually stop. In such a case, alert messages can never be received but an unnecessary service is running. This results in a waste of resources. In addition, whenever you change this status to Receive valid (green), the following error message appears: "Failed to start the service. : (Alert Manager Socket(R) Service)"
– | When you have changed from Receive invalid (red) to Receive valid (green): Although the following message appears, the status of each item is changed to "Receive valid (green)" for "Receive from Agent (TCP/IP)." However, alert messages cannot be received because the service (Alert Manager Socket(R) Service) failed to start. "Failed to start the service. : (Alert Manager Socket(R) Service)"

[Work Around]

If you have changed each item on Receive from Agent (TCP/IP) as user without Administrators privilege, take the following procedure:

– | Log on as a user with Administrators privilege.
– | If you have changed each item from Receive valid (green) to Receive invalid (red), restore it to "Receive valid (green)", and change it to "Receive invalid (red)" again.
– | If you have changed each item from Receive invalid (red) to Receive valid (green), restore it to "Receive invalid (red)", and change it to "Receive valid (green)" again.

[Maps to be specified at autodiscovery]

After you execute Autodiscover on the Operation Window, maps may be displayed as if they were registered infinitely as shown below:

This problem occurs when a map whose name is the same as its parent map was created at autodiscovery.
In such a case, delete the second mapA(*) (in this example) to resolve the situation.

[About setting a Windows Firewall]

If the Windows Firewall is enabled, communication between NEC ESMPRO Manager and NEC ESMPRO Agent will be interrupted and the system will not work correctly.
To use NEC ESMPRO Manager with the Windows Firewall enabled, open the following ports:
[Target Ports]
The following table shows the ports for the Windows Firewall to be set on the [Add a Port] dialog box on a machine on which NEC ESMPRO Manager is installed.

Name (can be changed) | Port number | Protocol | Environment
Inter-Manager communication | 8806 | TCP | When Inter-Manager communication is used.
SNMP Trap | 162 | UDP | When Manager Notification (SNMP) is used (default).
High Reliable Notification | 31134 | TCP | When Manager Notification (TCP/IP in Band) is used.
Express Notification via Manager | 31136 | TCP | When Express Notification Service is used via Manager.

| For ports used by NEC ESMPRO Manager, see Appendix "Port numbers that NEC ESMPRO Manager uses".

<Monitoring a server where multiple IP addresses are set for a single network card.>
[Problem]
If a monitored server has multiple IP addresses for a single network card, the IP address of the SNMP Response packet from NEC ESMPRO Agent may differ from the destination address in the IP header of the SNMP Request packet from NEC ESMPRO Manager.
In such a case, if NEC ESMPRO Manager receives the Response packet from NEC ESMPRO Agent before Windows Firewall Service starts, the server cannot be monitored thereafter.
[Work Around]
On the Operation Window of the NEC ESMPRO Manager, open [Properties] on the server icon, change the IP address to another one that is set on the monitored server, and reboot the Manager computer.

[About autodiscovery of Blade Servers]

When you execute Autodiscover and register blade servers, the number of slots for storing blades may be displayed differently from the actual one, and some blade images may be placed out of the frame. In such a case, follow the steps below to change map properties on the Operation Window:

1. | Right-click the target blade map icon, and select [Properties] from the pop-up menu.
2. | Double-click [Background], and select an appropriate background image.
3. | Double-click [Maximum Number of Blade Slot in Chassis], and set an actual maximum number of slots.
4. | Click [OK] to complete the settings.

[About autodiscovery of SIGMABLADE]

When CPU blades are autodiscovered before EM Cards are done, the autodiscovered CPU blades will be registered directly under the network map that you specified at autodiscovery, not under a blade map. In such a case, delete the registered CPU blades, and autodiscover them again as follows:
<When EM Cards and CPU blades are in the same segment>
Register EM Cards first, and then autodiscover corresponding CPU blades, or specify the range of the addresses to include the EM Cards and the CPU blades that are in the same Blade Enclosure and autodiscover them.
<When EM Cards and CPU blades are in different segments>
Register EM Cards first, and then autodiscover the corresponding CPU blades.

[About display of the network speed on the DataViewer]

– | When you monitor Linux servers, Speed will not be displayed on the Network General view of DataViewer. In such a case, check it on monitored servers.
– | When you monitor Windows servers which have network interfaces of which speeds are 10Gbps or over, Speed may not be displayed correctly on the Network General view of DataViewer. In such a case, check it on the monitored servers.
– | When you monitor Windows Server 2008 servers which have network interfaces with which a cable is not connected, an incorrect value (4,294 Mbps) may be displayed for the Speed on the Network General view of DataViewer.

[About display of the network status on the DataViewer]

When you monitor a server with Windows Vista installed, the message "Dormant" appears for Status on the Network General window of the DataViewer even if the network properly works. In such a case, check the network status on the monitored server.

[About display of the teamed network interfaces on the DataViewer]

If network interfaces are teamed on a server with Windows Vista / Windows 7 /Windows Server 2008 / Windows Server 2008 R2 installed, the network information may not be properly displayed on the DataViewer. Check it on the monitored server.

[About coexistence of NEC ESMPRO Manager
with HP OpenView Network Node Manager (NNM)]

• | To install NNM on the environment where the NEC ESMPRO Manager has been installed, take the following steps before installing NNM:
1. | Select [Options] – [Customize] – [My Manager] on the Operation Window and set the Method of receiving SNMP Trap to "Use SNMP Trap Service" on the My Manager dialog box.
2. | After the above, the dialog stating that "Changes will take effect after the computer has been restarted" appears. Exit the Operation Window and then take the following steps without shutting down and restarting the system
3. | Exit all applications related to NEC ESMPRO, such as AlertViewer, DataViewer, and GraphViewer.
4. | Exit "ESM Base Service" (and other dependent services) by selecting [Administrative Tools] – [Services].
After the above, install NNM and restart the computer.
• | To install NEC ESMPRO Manager on the environment where NNM has been installed, restart the computer and take the following steps after the installation of NEC ESMPRO Manager completes: Select [Options] – [Customize] – [My Manager] on the Operation Window and set the Method of receiving SNMP Trap to "Use SNMP Trap Service" on the [My Manager] dialog box. After the above, restart the computer.
