71.1 Statistics presentation

You can view all statistics types that the 5620 SAM supports in tables or graphs.

Tables list specific values, and the table data can be sorted, filtered, and exported to

files in different formats. Graphs help to identify trends, and can display multiple

statistics counters simultaneously. A graph can have multiple independently scaled

axes that allow a 5620 SAM operator to visually compare statistics with high

numbers, such as throughput statistics, to statistics with very low numbers, such as

dropped packet statistics. You can export graphs to files using different file formats.

There are two methods of specifying the statistics to present in a table or graph.

• bottom-up method—applies to performance and accounting statistics, and

involves navigating to the object on which the statistics are collected, such as a

SAP, SDP, or network port

• top-down method—applies to all statistics types, and involves opening a browser

form using the Tools→Statistics Browser option in the 5620 SAM main menu

You can display statistics from multiple objects in one list using a filter, choose

a specific statistics type, filter on a specific object, and view the statistics in a

table.

Tabular statistics view

Statistics for a single object are viewable in the Statistics tab of the object properties

form. Each displayed statistics class corresponds to a MIB table or to an accounting

file on the NE. When a collection policy is applied, the list is populated with rows of

statistics that are collected from the MIBs or accounting files specified in the policy.

You can also collect network and server performance statistics on demand by

clicking on the Collect button in the Statistics tab. The MIB associated with the

selected statistics type is polled and one row appears in the statistics list. The record

type is On-Demand, which indicates that the row is not collected using a collection

policy.

The Collect All button collects one on-demand statistics record for each statistic type

that the object supports. This is useful for collecting different types of statistics at the

same time.

On-demand collection is not available for accounting statistics. Accounting statistics

are available only in the 5620 SAM after an NE transfers an accounting statistics file

to the 5620 SAM.

The top section of a statistics tab contains a drop-down menu of statistics classes for

the object, and a filter that you can configure to limit the number of listed statistics,

for example, statistics collected during a specific time period. You can open a listed

entry to display a Statistics Record form that lists each counter and value, and

contains details about the record collection.

You can quickly sort a list of statistics by clicking on a list column heading, for

example, Time Captured or Record Type, and can customize the sorting by

right-clicking on the list heading and choosing Show Sorting from the contextual

menu.

You can export the statistics list to a file by right-clicking on the list heading and

choosing Save to File from the contextual menu.
