Current Performance Data is collected from a device instantly and shown in graphs and tables.

Differentiating Historical and Current Performance Data
Current performance data is collected from the device instantly and depicted in graphs and reports. On request, Web NMS queries the devices and collects data instantly. The current data is not stored in the database.
Current performance data when viewed in graph/tables are updated (based on predefined interval) as you view it. |
You can view current performance data in graphs, in a table view, or using Monitor Collections option.
To view current performance data using graphs
Open the Application Client.
Click Performance > Configured Collection node in the tree.
Click the host in the Hosts column in Configured Collection window. The statistics are displayed in the next column.
Click the row (statistic) for which you need view the graph and perform any of the following.
From View menu, choose Plot > Current Statistics.
Right-click the row and choose Plot > Current Statistic.
Press Ctrl+Shift+P.
The CurrentGraphViewer window is displayed.
The CurrentGraphViewer window displays the graph (by default, Line Chart) with current performance data plotted in it. There are five types of graphs that you can view:
Line Chart
Bar Chart
Area Chart
Scatter Chart
X-Y Chart
To save the graph to a file, click Save.
To clear the graph, click Clear Graph.
By default, the performance data from the device is plotted in the graph every 15 seconds. To change this interval, click Stop Poller. Enter the new interval (in seconds) in the spin box. Click Start Poller. The performance data is now plotted based on the newly configured interval.
To print the graph, right-click the graph and choose Print... Note: Right-click the graph also for performing operations such as zooming in and out, saving and setting properties.
To exit the CurrentGraphViewer window, click Exit.

Does your graph display any of the following messages?
Reason: The data is being collected from the device.
Reason: There is either a delay in the agent's response or the agent is down. Hence try contacting the agent for its status.
Reason: This is no response from the agent running in the device.
Reason: The collected data from the device is of string type. Hence the graph is not plotted. |
|
Does your graph display only a zero value?
This is because a constant value would have been got from the agent for the first two observations. Hence, the difference will be zero, and this is shown in the graph.
Note: This tends to happen as the saveAbsolutes property value of a statistic is set false by default. Had the saveAbsolutes value been set true, then, only the absolute value will be plotted and you will not encounter 'zero' often. |

By default, this facility is not available in the Application Client unless your administrator has provided the option. |
To view current performance data using table
Open the Application Client.
Click Performance > Configured Collection node in the tree.
Click the host in the Hosts column in Configured Collection window. The statistics are displayed in the next column.
Click the row (statistic) for which you need to view the graph and perform any of the following.
From View menu, choose Plot > Current Statistic Table.
Right-click the row and choose Plot > Current Statistic Table.
The ShowValue window is displayed. This depicts the time of performance data collection and the collected value.
By default, the performance data from the device is displayed in the table every 15 seconds. To change this interval, click Stop. Enter the new interval (in seconds) in the Interval field. Click Start. The performance data is now displayed based on the newly configured interval.
To exit the ShowValue window, click Close.
Using Monitor Collections Option
To view performance data
Open the Network Database > Nodes view.
Click any SNMP node in the table view (select the row corresponding to that SNMP node). Perform any of the following.
From Performance menu, choose Monitor Collections.
Right-click the row and choose Performance > Monitor Collections.
The Performance Monitoring window with statistics details is displayed.
Click a statistic in Polled Statistics and click Register. Based on the poll interval (displayed in Poll period field), the performance data is collected and displayed in the Value field.
To view the collected performance data using graphs, click Collected Statistics. To view the current performance data using graphs, click Current Statistics. To view reports, click Report.
Tip: The Monitor Collections option is also available in the maps.
