When you choose Raw, the bar chart view is sometimes not available, and the
Summary Rule option is grayed out.
In some circumstances (possibly due to Cisco 12000/10720 Router Manager being shut down or
a heavy network load), polls can be missed. Performance Manager deals with this problem by
displaying missed polls in red. The missed poll value is replaced by the last valid value collected.
Performance Manager graphs and charts also indicate when an attribute started and stopped
being polled due to history storage criteria being added, edited or removed. Start and stop polling
events are shown in charts and tables. The start polling events point is shown in green, and the
stop polling events point is shown in red.
