The root cause status indicator enables you to view a list of nodes that have been identified as the
root cause of an outage. If the indicator is green with a check mark, there are no root causes
associated with managed nodes. If the indicator is red with an exclamation point, it provides a link
to the
View >
Root Causes
page. If the indicator is red and the exclamation point is flashing, at
least one root cause has occurred since the most recent viewing of the
View >
Root Causes
page
.
The inventory bars display the current status of the ZoneRanger managed nodes categorized by the
following types:
•
Routers
•
Switches
•
Web servers
•
Servers
Note:
Some nodes may appear in multiple categories. For example, a Solaris server that is also
running a web server appears in both the Server and Web Server categories.
Each inventory bar represents a type of node and uses color to display the status of nodes of that
type. The proportion of each color in an inventory bar represents the proportion of nodes of that
type that have a particular status.
For example, if ZoneRanger is managing 20 routers and a quarter of the
Routers
inventory bar is
yellow, five of the routers are
marginal
(the following section describes colors that can appear in the
inventory bars). The total number of devices in a category appears in a number at the right of the
inventory bar for the category. You can mouse over the inventory bar to see a count of devices
associated with each status.
Color
Description
Green
Represents nodes that are up. This node status is called
normal.
Yellow Represents nodes for which at least one interface or TCP
port is down, but at least one interface or TCP port is
up. This node status is called
marginal
.
Red
Represents nodes that are down. This node status is
called
critical
.
Blue
Represent nodes whose status is
unknown
. Such devices
are configured for polling but have not yet been polled,
or are not configured for polling.
Statistics Section
The Statistics section displays various charts showing proxy and forwarding traffic over the
previous 4.5 hour period, as well as information about the ZoneRanger itself. The information
displayed is based on statistics values which are cached by the ZoneRanger application software.
These statistics values can be viewed on the
View > Statistics
page. The displayed values are since
the ZoneRanger started or since the values were reset on the
View > Statistics
page. These values
are not historically ed. These Statistics are also available via the ZoneRanger SNMP agent.
The
View > Preferences
page can be used to customize which Chart appears first on the
ZoneRanger Dashboard and which protocols are displayed on the Forwarding chart. Preferences are
configured on a per user basis.
