18 Setting up management hubs
18.1 About management hubs
A
is an aggregation point for management activities. Insight Control for Linux
uses management hubs to distribute the management load across multiple servers. HP
recommends creating multiple management hubs if you plan to monitor over 256 managed
systems.
You have the option of choosing any physical server to act as a management hub; you can elect
to use the
as a management hub or not. If you do not specify a management hub, the CMS
becomes the sole management hub by default.
IMPORTANT:
•
HP recommends the use of physical servers for use as management hubs.
•
Only servers running a supported version of RHEL or SLES (that is, supported as a CMS)
can act as management hubs. Furthermore, the operating systems of the CMS and the
management hub must have the same architecture (32-bit or 64-bit) although they can have
different OS types (RHEL or SLES).
•
Each managed system is assigned to a management hub automatically when you run
Options
→IC-Linux→Configure Management Services.
illustrates this structure.
Figure 18-1 Management hub aggregation
HP recommends that you create at least one management hub for every 256 servers. For example,
if you plan to monitor 1000 servers, create a minimum of 4 management hubs.
The management hub also runs the
aggregator (supermond) and
(nagios_monitor) services.
