Hi ,
I am trying to extract VIF metrics data of all the VMs on a Citrix Xen host.
I wrote the code as follows to iterate the VIF sets in all VMs and from the VIF
record of each VIF get the VIF metrics.
The VIF metrics like I/O read / write rates are not available.
Please guide whether I am doing something wrong.
session = XenAPI.xapi_local(
session.xenapi.login_with_password("root","")
all = session.xenapi.VM.get_all()
try:
for vm in all:
try:
record = session.xenapi.VM.get_record(vm)
if not record["is_control_domain"] and not
record["is_a_template"] and record["resident_on"]
:
domid = record["domid"]
name = record["name_label"]
vif_set = session.xenapi.VM.get_VIFs(vm)
for vif in vif_set:
vif_metrics =
session.xenapi.VIF.get_metrics(vif)
vif_rec =
session.xenapi.VIF.get_record(vif)
mac_addr = vif_rec["MAC"]
metrc =
session.xenapi.VIF_metrics.get_record(vif_rec["metrics"])
# I have
removed the code to extract io_read and io_write at this point of time .
loca_str = '%s,%s,%s,%s,%s\n' % (domid
, name , mac_addr ,io_read ,io_write)
csv_string = csv_string + loca_str
domid = ""
name = ""
mac_addr = ""
io_read = ""
io_write = ""
except Exception, e:
print "Exception 1",e
loca_str = '%s,%s,%s,%s,%s\n' % (domid , name
, mac_addr ,io_read ,io_write)
csv_string = csv_string + loca_str
except Exception ,e:
print "Exception 2",e
loca_str = '%s,%s,%s,%s,%s\n' % (domid , name , mac_addr ,io_read
,io_write)
csv_string = csv_string + loca_str
Program output is as follows
