+# Perquisite: For "disk" case and "netdisk" case you need to have lustre setup

+# $ nobjhi=2 thrhi=2 size=1024 case=disk sh obdfilter-survey
+# one can also run test with user defined targets as follows,
+# $ nobjhi=2 thrhi=2 size=1024 targets="lustre-OST0000 lustre-OST0001 ..." sh obdfilter-survey
+# case 2 (network):
+# $ nobjhi=2 thrhi=2 size=1024 targets="<name/ip_of_server>" case=network sh obdfilter-survey
+# where, targets is name or ip address of system, which you want to
+# set as server.
+# case 3 (network and disk):
+# $ nobjhi=2 thrhi=2 size=1024 case=netdisk sh obdfilter-survey
+# one can also run test with user defined targets as follows,
+# $ nobjhi=2 thrhi=2 size=1024 targets="<osc_name> ..." sh obdfilter-survey
