Hypervisor monitoring

NetXMS has subagents that allow to monitor hypervisors. This subagent is build using libvirt functionality.

Configuration is separeted to two parts. In “vmgr” part are defined all monitored hosts. Host configuration is descibed afterwards in separate section for each host.

Each host configuration should contain connection URL. Login and password parameters are optional. URL creation rules for each vitalization solution type can be found in libvirt documentation: http://libvirt.org/drivers.html.

Configuration example

In example are defined 2 hosts: localESX1 and test. localESX1 connection details are described in “vmgr:localESX1” section and test connection details are described in “vmgr:test” section.
