Thanks Jason

adding prometheus_host = 0.0.0.0 to iscsi-gateway.cfg does not work - the
error message is

"..rbd-target-gw: ValueError: invalid literal for int() with base 10:
'0.0.0.0' "

adding prometheus_exporter = false works

However I'd like to use prometheus_exporter if possible
Any suggestions will be appreciated

Steven
