Figure 4-3	Service Template SLOs

An SLO speciﬁes the level of service that you expect to provide. They can be conﬁgured to set a minimum average response time, the maximum concurrent sessions supported, and to meet an externally speciﬁed measurement.

WebQoS monitors the SLOs to make sure they are met. If they are not met, WebQoS will execute any conﬁgured corrective actions.

If you have conﬁgured an SLO, the results can be viewed from the management console’s main screen. For more information on statistics, see “Service Statistics” on page 86.
