♦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.
