How do I navigate the network hierarchy?
The Filter bar at the top of the screen provides a way to navigate through the network hierarchy (see File>Configure to see how to group network devices). At the top level, a list of Zones is shown, once you have selected a zone, the view will drill down to only show information from the selected zone, and a list of Groups will appear. Select a group and the view will drill down to only show the information from the selected group and a list of Agents will appear. Finally if you select an agent, its Interfaces will be shown. Click on the links at any level in the path and you will move back up the tree to that level. Click on the Show Map button to view a map of the selected part of the network (see Sentinel:Maps>Layer 2). If a single agent has been selected an Agent Details button will appear. Click on the button to see detailed information about the agents (see Sentinel:Search>Agent/Interface).
How can I organize the data in the table?
The following options in the Filter are used to select and sort the entries in the table:
- Show provides two ways of viewing the interface statistics: Status displaying how close each metric is to its threshold (see File>Configure for information on configuring thresholds) and Counters, displaying the actual counter values.
- Sort specifies the metric used to sort the table (Note: you can also change the sort column by clicking on the column title).
- Truncate controls the maximum number of interfaces that will be displayed.
What do the status bars show?
When the Show setting is set to Status, the status bars
are computed based on the threshold that have been set
for the particular statistic. Green
indicates that there have been no threshold violations within
the threshold interval (the height of the bar indicates how close the current
value is to the threshold - in this case the bar is half way to the tick marks
indicating 50% of threshold). Yellow
indicates that there has been at least one threshold
crossing, but that the duration of the violation isn't yet sufficient to
generate an event (the height of the bar above the tick marks indicates how
close the status is to generating an event - in this case the bar is half way
between the tick marks and the maximum value indicating that twice the
number of threshold violations is needed before an event will be generated).
Finally red
indicates that threshold crossings have met the
frequency and duration criteria for generating an event (the height of the bar
indicates how close the status is to clearing the event - in this case the
bar is half way between the maximum value indicating that half the number
of intervals needed to clear the event have occurred, proving that the
value remains below the threshold.) See
File>Configure
to see how to set thresholds.
When the Show setting is set to Counters the bars represent the maximum ingress or egress value of each metric for the interface.
