Hello, We can have combination. Please see below example. To exclude instances with different health status: python dellemc_device_check.py --host= --devicetype=iDRAC --componentname=Controller --protocol=2 --http.user= --http.password= --http.timeout=30 --http.port=443 --http.retries=1 --logPath=None --excludeinstance=" Status==Unknown,Status=OK"  We can pass any attribute for "--excludeinstance". Mix of multiple attributes also supported. Please see below example. This will exclude the instances with "Status=OK" and "FQDD=AHCI.Embedded.1-1" python dellemc_device_check.py --host= --devicetype=iDRAC --componentname=Controller --protocol=2 --http.user= --http.password= --http.timeout=30 --http.port=443 --http.retries=1 --logPath=None --excludeinstance=" Status==OK,FQDD==AHCI.Embedded.1-1"  Thanks & Regards,Rajshekar P
