@AntonyStone have you any idea how many Nodes Network and System Monitoring solutions it supports?
and
Does support for HCI solution of H3C and Sanfor?

icinga supports everything there is a plugin for. You can use icinga plugins or nagios plugins.
You can use snmp to check some components or even write your own checks in a program language that a icinga supported OS supports.

you can find various checks on exchange.icinga.com, exchange.nagios.org or github
