Smart Alerts
A Smart Alert is triggered when an internally calculated value indicates that a problem occurs, or soon will
occur. The internally calculated value can be a correlated prediction of future behavior or a dynamic threshold
breach on a KPI. Except for metrics that are designated as KPIs, Smart Alerts do not depend on user-defined
values. Smart Alerts have certain subtypes.
Table 4-5. Smart Alert Subtypes
Subtype Description Determined By
KPI DT Breach A KPI breached one of its internally calculated
dynamic thresholds.
Analytics based on a user-defined
KPI.
KPI Prediction vCenter Operations Manager predicts that a
KPI will soon breach a threshold. The current
combination of metrics might match a stored
metric fingerprint that predicts the breach, or
a metric that is correlated with the KPI has
breached its threshold.
KPI Prediction alerts are always critical.
Analytics based on a user-defined
KPI.
Early Warning vCenter Operations Manager correlation
algorithms calculate a greater than 90 percent
chance above the noise threshold that there is
a problem with an application.
Early Warning alerts are always critical.
Analytics based on application
topology.
Classic Alerts
A classic alert is an alert that is generated by classic monitoring software. It relies on user-defined hard
thresholds, not vCenter Operations Manager dynamic thresholds or other advanced calculations. Classic alerts
have certain subtypes.
Table 4-6. Classic Alert Subtypes
Subtype Description Reason
KPI HT Breach A user-defined KPI breached a user-
defined hard threshold.
A user-defined KPI breached one of its user-
defined hard thresholds.
Abnormality A non-KPI metric breached one of its
internally calculated dynamic
thresholds.
A single non-KPI metric breached one of its
dynamic thresholds.
Notification A non-KPI metric breached a user-
defined hard threshold. Typical system
and network management applications
send this type of alert.
A single non-KPI metric breached one of its
internally calculated dynamic thresholds.
Administrative Alerts
An administrative alert indicates a problem with vCenter Operations Manager, the monitoring software from
which it collects data, or the enterprise network. Administrative alerts have certain subtypes.
Table 4-7. Administrative Alert Subtypes
Subtype Description
System A vCenter Operations Manager component failed.
Environment vCenter Operations Manager stopped receiving data from
one or more resources. A problem might exist with the
resource, the monitoring software, or the network
infrastructure.
