Configuring WLM
Defining SLOs
Chapter 5 207
Is an expression that must be true for the SLO to be
active.
NOTE Do not create a condition statement that attempts to
detect processes in a transient group using tools such
as glance or ps. Whenever the group is deleted (FSS
group) or assigned zero CPU resources (PSET-based
group), it is impossible for the system to place
processes in the group. The condition will then never
detect the processes it is looking for.
exception_expression
Is an expression that must be false for the SLO to be
active.
Use the following components to form either of the expressions:
• metric met > numeric_value
• metric met < numeric_value
• metric met
•Date
• Date range
Combine components to form Boolean expressions with the operators
&& (AND), || (OR), ! (NOT). Group components with parentheses ().
met must have an associated tune structure. numeric_value must be a
floating-point value, either positive or negative. The metric met
expression is false if met equals 0. For all other values, the expression is
true.
In a Serviceguard cluster, where workloads may move between servers,
use metric met to inform WLM of the active workloads. Ideally, a single
WLM configuration file can be used on all the servers in the cluster. For
more information, see “Integrating with Serviceguard” on page 414.
Specify dates or date ranges in condition_expression and
exception_expression using the following components:
[weekday] [mm/dd/ccyy] [hh:mm]
