Argument syntax example Description
funct(${adapterkind=adaptkind,
resourcekind=reskind, resourcename=resname,
identiers={id1=val1id2=val2,…}, metric=a|
b:instance|c})
Returns a single data point of a particular metric for the resname
specied in the argument. This super metric does not take values
from the children or parents of the object.
funct(${adapterkind=adaptkind,
resourcekind=reskind, resourcename=resname,
identiers={id1=val1, id2=val2,…}, aribute=a|
b:optional_instance|c})
Returns a set of data points. This function iterates aributes of the
resname specied in the argument. This super metric does not take
values from the child or parent of the object.
funct(${adapterkind=adaptkind,
resourcekind=reskind, depth=dep}, metric=a|
b:optional_instance|c})
Returns a set of data points. This function iterates metrics of the
reskind specied in the argument. This super metric takes values
from the child (depth > 0) or parent (depth < 0) objects, where depth
describes the object location in the relationship chain.
For example, a typical relationship chain includes a datacenter,
cluster, host, and virtual machines with the datacenter at the top
and the virtual machines at the boom. If the super metric is
assigned to the cluster and the function denition includes depth =
2, the super metric takes values from the virtual machines. If the
function denition include depth = -1, the super metric takes values
from the datacenter.
funct(${adapterkind=adaptkind,
resourcekind=reskind, depth=dep}, aribute=a|
b:optional_instance|c})
Returns a set of data points. This function iterates aributes of the
reskind specied in the argument. This super metric takes values
from the child (depth > 0) or parent (depth < 0) objects.
For example, avg(${adapterkind=VMWARE, resourcekind=VirtualMachine, attribute=cpu|usage_average,
depth=1}) averages the value of all metric instances with the cpu|usage_average aribute for all objects of
type VirtualMachine that the vCenter adapter nds. vRealize Operations Manager searches for objects one
level below the object type where you assign the super metric.
Single Functions
Single functions work on only a single value or a single pair of values.
