You need to install a complete SPP for all tools, drivers and Firmware. This will cause downtime as you will probably need to update NIC drivers and BIOS for the server. Is it a problem to have downtime ?
For monitoring you only need SMH and WBEM or SNMP agents installed. Windows 2016 is not supported in terms of agents so i would try the X64 2008 agents or just the latest SPP to see what is still supported for your G7 DL380. If i look at a Gen9 there is support for Windows 2016 but just not for your hardware setup. For the wbem agent i would install this one : http://h20566.www2.hpe.com/hpsc/swd/public/detail?sp4ts.oid=1009087945&swItemId=MTX_9015eb99985e44f09bb30bcfe9&swEnvOid=4231#tab1
