HP Device Monitor (v 1.1) for Microsoft System Center User Guide

Suggested action
Connect the DMC to a locally-installed instance of the DMS. If a local connection to the DMS is
not possible, advanced users can perform the following steps on the multihomed system on which
the DMS is installed:
1. Use the Windows Service Control Manager to stop the HP Device Monitor Service.
2. Back up the following file (where installation-path is the location specified in the installer when
you installed the DMS):
installation-path\HP SCOM Management Packs\HP Device Monitor Service\
HPDeviceMonitor.exe.config
3. Use a text editor to make the following changes to the HPDeviceMonitor.exe config file:
a. Locate the line that contains this text:
<channel ref="tcp" port="5317" secure="true"
protectionLevel="EncryptAndSign" impersonate="true">
b. Add the text bindTo=”<IPAddress>”as shown in bold in this example:
<channel ref="tcp" port="5317" bindTo=”<IPAddress>” secure="true"
protectionLevel="EncryptAndSign" impersonate="true">
c. Replace <IPAddress> with an IP address, in the same network as the DMC, that the
DMC can use to communicate with the DMS on this server. For example:
<channel ref="tcp" port="5317" bindTo="192.168.0.100"
secure="true" protectionLevel="EncryptAndSign" impersonate="true">
4. Use the Windows Service Control Manager to start the HP Device Monitor Service.
5. Use the DMC to remotely connect to this instance of the DMS.
Checking DMS operation
If a problem with the DMS has occurred, first perform the following steps:
1. Launch the DMC to determine whether the DMS is working. If it is, you can log in and see the
list of managed devices.
2. Determine whether the DMS has reported an alert. View alerts by selecting the HP
Systems→Active Alerts view in the SCOM console.
Windows SNMP Trap Service is required for DMS but is disabled on servers using
SCOM 2012 for network monitoring
The DMS requires the SNMP Trap Service to process SNMP traps. However, when a computer is
used as a management server or gateway server for network monitoring using SCOM 2012, the
SNMP Trap Service is disabled. Consequently, the DMS cannot process SNMP trap events on that
computer.
Suggested action
Install the DMS on an agent-managed computer that meets all the prerequisites described in the
HP SCOM Management Packs User Guide.
SCOM does not discover devices
Every device must be registered with a DMS instance through the DMC. Use DMC to review DMS
connections and each of the monitored devices.
The updated registration information appears immediately in the DMS. Any errors are reported in
HP Device Monitor Log (in the NT Event Log). However, the SCOM discovery process does not
occur immediately. The discovery results do not appear on the management console until after the
