You can include any of the data points or thresholds from a monitoring template in a performance graph. To define a graph:

1. Select Advanced from the Navigation menu, and then select Monitoring Templates. 2.

In the Graph Definitions area, click (Add Graph). The Add Graph Definition dialog appears.

3. Enter a name for the graph, and then click Submit.

4. Double-click the graph in the list to edit it. Enter information or select values to define the graph:

• Name - Optionally edit the name of the graph you entered in the Add a New Graph dialog. This name appears as the title of the graph.

• Height - Enter the height of the graph, in pixels. • Width - Enter the width of the graph, in pixels. • Units - Enter a label for the graph's vertical axis.

• Logarithmic Scale - Select True to specify that the scale of the vertical axis is logarithmic. Select False (the default) to set the scale to linear. You might want to set the value to True, for example, if the data being graphed grows exponentially. Only positive data can be graphed logarithmically.

• Base 1024 - Select True if the data you are graphing is measured in multiples of 1024. By default, this value is False.

• Min Y - Enter the bottom value for the graph's vertical axis. • Max Y - Enter the top value for the graph's vertical axis.

• Has Summary - Select True to display a summary of the data's current, average, and maximum values at the bottom of the graph.

6.2.8.1. Graph Points

Graph points represent each data point or threshold that is part of a graph. You can add any number of graph points to a graph definition by adding data points or thresholds.

From the Graph Definitions area of the Monitoring Templates page: 1. Select Manage Graph Points from the Action menu.

The Manage Graph Points dialog appears.

2. From the Add menu, add a data point, threshold, or custom graph point. 3. Select values, and then click Submit.

the new graph point appears in the Graph Points list.

Note

Thresholds are always drawn before other graph points.

6.2.8.1.1. Re-sequencing Graph Points

To re-sequence graph points, drag a graph point row in the Manage Graph Points dialog. (Click and drag from an "empty" part of the row.)

6.2.8.1.2.1. Adding DataPoint Graph Points

To define a DataPoint graph point:

1. From the Add menu on the Manage Graph Points dialog, select Data Point. The Add Data Point dialog appears.

2. Select one or more data points defined in this template. On data point graph point is created for each data point you select from the list.

3. Optionally select the Include Related Thresholds option. If selected, then any graph points are created for any thresholds that have been applied to the selected data points as well.

4. Click Submit.

6.2.8.1.2.2. Editing DataPoint Graph Points

Double-click the name of the graph point to go to its edit page. Enter information or select values to edit the graph point: • Name - This is the name that appears on the Graph Definition page. By default, it appears in the graph legend. • Line Type - Select Line to graph the data as a line. Select Area to fill the area between the line and the horizontal

axis with the line color. Select None to use this data point for custom RRD commands and do not want it to be explicitly drawn.

• Line Width - Enter the pixel width of the line.

• Stacked - If True, then the line or area is drawn above the previously drawn data. At any point in time on the graph, the value plotted for this data is the sum of the previously drawn data and the value of this data point now. You might set this value, for example, to asses total packets if measuring packets in and packets out.

• Format - Specify the RRD format to use when displaying values in the graph summary. For more information on RRDTool formatting strings, go to:

http://oss.oetiker.ch/rrdtool/doc/rrdgraph_graph.en.html

• RPN - Optionally enter an RPN expression that alters the value of the data being graphed for the data point. For example, if the data is stored as bits, but you want to graph it as bytes, enter an RPN value of "8,/" to divide by 8. For more information about RRDTool RPN notation, go to:

http://oss.oetiker.ch/rrdtool/tut/rpntutorial.en.html

• Limit - Optionally specify a maximum value for the data being graphed.

• Consolidation - Specify the RRD function used to graph the data point's data to the size of the graph. Most of the time, the default value of AVERAGE is appropriate.

• Color - Optionally specify a color for the line or area. Enter a six-digit hexadecimal color value with an optional two-digit hex value to specify an alpha channel. An alpha channel value is only used if 'stacked' is True.

• Legend - Name to use for the data in the graph legend. By default, this is a TALES expression that specifies the graph point name. The variables available in this TALES expression are here (the device or component being graphed) and graphPoint (the graph point itself).

• Available RRD Variables - Lists the RRD variables defined in this graph definition. These values can be used in the RPN field.

6.2.8.1.3. Editing Threshold Graph Points

Threshold graph points graph the value of thresholds from the template. To edit a threshold graph point, double-click it in the list:

You can edit values for Name, Color, and Legend for a threshold graph point. Refer to the definitions in the section titled Editing DataPoint Graph Points for more information.

6.2.8.1.4. Editing Custom Graph Points

Custom graph points allow you to insert specific RRD graph commands into the graph definition. For details on DEF, CDEF, and VDEF commands, go to:

6.2.8.1.5. Setting Up ping RTT and Packet Loss Graphs

You can use zenping to produce ping round-trip time (RTT) and packet loss graphs.

Figure 6.15. Ping Data Source

1. On your ethernetCsmacd templates (or other interface templates), add a data source named Ping, of type PING. The data source is added, and automatically includes several rtt data points.

Available statistics for data points include: • sent • rcvCount • loss • rtt • rtt_max • rtt_min • rtt_avg • rtt_stddev • rtt_losspct

6.2.8.2. Custom Graph Definition

Custom graph definitions allow you to specify your own set of RRD commands to draw a graph. The graph points specified are used to define data that is available to the commands you specify here; however, the graph points are not drawn unless you explicitly draw them with the commands you specify. The Available RRD Variables lists the values defined by the graph points that are available for use.

Core Monitoring

To access custom graph definitions, select Custom Graph Definition from the Action menu in the Graph Definitions area.

6.2.8.3. Graph Commands

Graph Commands show an approximate representation of the RRD commands that will be used to draw a graph. This representation provides helpful debugging information when using custom graph points or custom graph definitions. To view graph commands, select Graph Commands from the Action menu in the Graph Definitions area.
