7.1.3 Collecting host information

IM Configuration Management can collect host information stored in JP1/Base on agents and host information on the remotely monitored hosts, and then apply the information to the IM Configuration Management database. However, when you collect host information on remotely monitored hosts, host information cannot be collected if OS communication is set to off in the OS communication settings.

Collect host information on the Host List page or IM Configuration page of the IM Configuration Management window.

The collected host information is saved to the IM Configuration Management database, replacing the existing data.

If host information is to be collected while a remote-monitoring log file trap or remote-monitoring event log trap is running on a selected host, the host information is collected according to the reply to the confirmation message. Remote monitoring is stopped when host information is to be collected but no information can be obtained from the monitored host, or when the OS name differs from the OS name used for a previous collection.

To collect host information from remotely monitored hosts, a WMI/NetBIOS (NetBIOS over TCP/IP) connection is used for Windows, and an SSH connection is used for UNIX.

The figure below shows an example of the host information registered in the IM Configuration Management database when collection is performed.

Figure 7‒2: Example of host information registered in the IM Configuration Management database when collection is performed

The following table describes host information that can be collected on each type of host.

Table 7‒3: Host information that can be collected
Host information		Host in agent configuration (When JP1/Base version 9 or later is used)	Remotely monitored host
IP address^#		Y	Y
Host name list		Y	Y
Host type		Y	N
Actual host name		Y	N
OS		Y	Y
Product information	Product name	Y	N
	Product module	Y	N
	Version	Y	N
	Installation path	Y	N

Legend:

Y: Can be collected.

N: Cannot be collected.

IP address whose name was resolved by the manager

The following table lists the JP1 products from which product information can be collected.

Table 7‒4: JP1 products from which product information can be collected
Product name	Product version	Whether collectable
JP1/Base	Version 9 or later	Y
JP1/IM - Manager	Version 9 or later	Y

Legend:: Y: Can be collected.

After host information is collected successfully from a host running JP1/Base version 9 or later, JP1/IM performs one of the following checks on the collected information, as applicable:

Host type determination

If the host information was collected from a host registered as Unknown type in the IM Configuration Management database, the host type is determined automatically. The registered host type is changed to the host type contained in the collected host information.

Host type determination does not distinguish between a physical host and a virtual host. If the host is actually a virtual host, after the determination you must change the host type to Virtual host and set a VMM host in IM Configuration Management - View.

For details about how to set the host type, see 7.1.5 Changing host information.

Host type check

If the host information was collected from a host registered as other than Unknown type in the IM Configuration Management database, its host type is verified. The registered host type is compared with the host type contained in the collected host information. If a mismatch is found, the host type registered in the database is judged to be incorrect and an error message is displayed.

The host type check does not distinguish between a physical host and a virtual host. The host is assumed to be a physical host in all cases. The following table describes the results of a host type check.

Table 7‒5: Results of a host type check
Host type of the collection target host	Host type registered in the IM Configuration Management database	Check result
Physical host	Physical host or virtual host	Y
Physical host	Logical host	N
Logical host	Physical host or virtual host	N
Logical host	Logical host	Y

Legend:

Y: Correct

N: Incorrect

Note:

If the host type is incorrectly specified as a physical host or virtual host in the IM Configuration Management database, the setting is not regarded as incorrect by the host type check.

On the Host List page of the IM Configuration Management window, you can check the status of the hosts after host information is collected. If collection fails for any host, the host's icon appears grayed in the tree display area. To see more details, click the Basic Information button in the node display area on the Host List page.
