13.3.12 Monitoring multiple sites
By using JP1/IM - Manager running on one integrated monitoring server, you can centrally monitor events that occur on monitored servers at multiple sites.
You can specify a desired host name and IP address for a monitored server running at each site, regardless of the host names and IP addresses of the monitored servers running at other sites. However, the host name and IP address must be unique within the same site.
For the integrated monitoring server and the site monitoring servers, specify host names and IP addresses that are unique within the system.
|
The following tables describe the prerequisites and limitations when host names and IP addresses are duplicated at different sites.
- Organization of this subsection
(1) Prerequisites
No. |
Server |
Prerequisite |
---|---|---|
1 |
Site monitoring server |
A site monitoring server on which JP1/IM - Manager and JP1/Base are installed is required for monitoring the monitored servers at each site. |
2 |
Site monitoring server Monitored server |
The target servers are monitored remotely from the site monitoring server. The integrated monitoring server cannot monitor remote servers that are subject to monitoring. If you use an agent configuration (JP1/Base is installed on a monitored server) for monitoring, configure a FQDN-format event server on the monitored server. For details, see the JP1/Base User's Guide. |
3 |
Integrated monitoring server Site monitoring server |
Set up an environment in such a manner that the integrated monitoring server and the site monitoring server can communicate with each other. |
4 |
Integrated monitoring server Site monitoring server |
The host names and IP addresses of the integrated monitoring server and the site monitoring servers must be fixed and unique within the system configuration. If you change the host name and IP address of a site monitoring server, you must check and, if necessary, revise settings such as filter conditions for JP1/IM - Manager and JP1/Base, and restart services. For details, see 2.2 Tasks necessary when a host name is changed and 2.3 Tasks necessary when an IP address is changed in the JP1/Integrated Management 2 - Manager Administration Guide. |
5 |
Monitored server |
The host names and IP addresses of monitored servers must be unique within the same site. |
6 |
Monitored server |
The host name of a monitored server must be fixed. If you change the host name of a monitored server, you must change the host information registered in the IM Configuration Management database. For details see, 3.1.5 Changing the attributes of host information in the JP1/Integrated Management 2 - Manager Configuration Guide. |
7 |
Integrated monitoring server Site monitoring server Monitored server |
If you use DHCP to connect to monitored servers, configure the environment so that the site monitoring server can dynamically resolve IP addresses from the monitored servers' host names by using, for example, DNS. Note that there is no need for the integrated monitoring server to resolve monitored servers' host names. If you use DHCP to manage the IP addresses of an integrated monitoring server and site monitoring servers, set the expiration of IP address allocation to infinite so that the IP addresses will never change. For details, see 13.4.1 Host names and IP addresses. |
8 |
Monitored server |
When you change the IP address of a monitored server, first stop the monitoring of that monitored server, change the IP address, and then restart the monitoring. The same applies when an IP address is reallocated by DHCP. You must also ensure that the site monitoring server can resolve the new IP address by using (for example) DNS. |
(2) Limitations
No. |
Condition |
Limitation |
---|---|---|
1 |
Employing a system hierarchy (configuring the integrated monitoring server and site monitoring servers in a hierarchy) by using IM Configuration Management |
IM Configuration Management of the integrated monitoring server cannot manage monitored servers. Do not set a site monitoring server at a site as a base manager for monitoring multiple sites. |
2 |
System configuration (remote monitoring of servers by a site monitoring server) |
For remote monitoring, the supported log file size and the maximum number of Windows event logs that can be acquired differ from those values for an agent configuration. For details, see 7.6 Managing remotely monitored hosts. |
3 |
Manipulating monitored servers |
The integrated monitoring server cannot manipulate monitored servers by using, for example, commands, because the integrated monitoring server cannot identify the monitored servers individually. |
4 |
Monitoring monitored servers by using the Intelligent Integrated Management Base |
The integrated monitoring server cannot uniquely identify monitored servers having the same name but installed on different sites. These servers can therefore not be monitored as different nodes in a tree view. |
