Alarms and their Status Indicators
vFoglight Cartridge for VMware uses status indicators to show that specific alarms have
been raised within the virtual infrastructure. Four status indicators, similar to those
displayed in Figure 5, are used throughout all of the vFoglight Cartridge for VMware
dashboards. The status indicators may be displayed as round and colored with the
number off to the side (as in Figure 5) or they may be displayed as rectangular and
colored with the number in the center of the indicator.

Figure 5 Status Indicators
The vFoglight alarm types respond to thresholds that are defined within the vFoglight
Cartridge for VMware rules. As metrics change and move through thresholds, alarms
are raised. As a metric moves through thresholds the severity of an alarm changes,
which causes the associated status indicator to change.
For detailed information about vFoglight Cartridge for VMware rules and metrics, refer
to the vFoglight Cartridge for VMware Reference Guide.
It is important to note that with vFoglight Cartridge for VMware an event that triggers
an alarm for an object does not trigger an alarm for any of the object’s parents. For
example, a single Virtual Machine running at a high CPU utilization does not trigger an
alarm for its parent ESX Server. An alarm would only be triggered for the parent ESX
Server if the server itself was running at a high CPU utilization.
