A custom properties file is specific to the agent for which it was created and cannot be shared among agents. You can use a custom properties file to configure the following:
Custom properties files consist of properties that you would not normally share across agents. For example, if you are monitoring 100 DLCIs on a Frame Relay segment, you would not want to log information for all 100, only for the DLCIs of interest. Similarly, you do not need multiple agents pinging the same network device or performing the same proxy SNMP queries on the same MIB object. You can install a custom properties file only on the agent for which you specifically create it.
You create a custom properties file by selecting the corresponding agent in Configuration Manager and launching Property Editor in Custom mode. Note that a custom properties file always assumes the name of the agent for which you create it. For example, if you select an agent named ET-111 and launch Property Editor in Custom mode, a custom properties file is created with a name of ET-111.
To create a custom properties file for a selected agent, take the following steps:
Step 1 Launch Configuration Manager by clicking the Config Manager icon in the TrafficDirector Admin level.
Step 2 Select the radio button for the type of agent for which you want to define custom properties. Select from the following device types:
Step 3 Select the agent, switch, or Frame Relay agent you want to work with.
Step 4 Select the Custom radio button.
Step 5 Click Property.
The Property Editor (Custom) window opens (Figure 12-1). If you have already defined custom properties for the selected agent, the custom properties file is opened. If you are configuring custom properties for the agent for the first time, the custom properties file is created.
Step 6 Configure custom properties. See Chapter 37, "Configuring Alarms."
You use custom properties files to configure logging for individual DLCIs and switch ports, and to configure round-trip delays and proxy SNMP gets. You configure custom properties files offline, then install them on the agent after all custom properties have been defined.
For DLCIs, you can configure logging for any domain you installed on the corresponding Frame Relay interface. For switch ports, you can define logging for the RMON domain only.
To define logging for an individual DLCI or switch port using a custom properties file, take the following steps:
Step 1 Launch Property Editor for the agent, switch, or Frame Relay agent for which you want to define custom properties. See "Creating Custom Properties Files."
Step 2 Select the Domain radio button.
Step 3 Click Add to the right of the Domain list box.
The Add Domain window opens. If you are configuring custom properties for a switch, a list of switch ports is displayed in the Port List box (Figure 12-2).
If you are configuring custom properties for a Frame Relay agent, a list of all DLCIs on the Frame Relay interface is displayed in the DLCI list box.
Step 4 Select the domain you want TrafficDirector to log from the Domains list box.
Step 5 From the drop-down menus under the Logging heading, select the polling interval for the Stats, Hosts, and Conversations statistical group, as required. This is the interval at which TrafficDirector will poll the specified DLCI or switch port for information.
Step 6 Do one of the following:
Step 7 Do one of the following:
You can configure round-trip delays for TrafficDirector agents that have the Resource Monitor option enabled. A round-trip delay is simply an IP ping to a specific host. When you install a custom properties file in which you have defined a round-trip delay on an agent, you configure that agent to ping a specified host at a defined interval to ensure that it is alive on the network, and measure the time it takes for the device to respond to the ping. You can also set alarms on the number of pings failed or average response time. See "Editing Alarm Configurations" in Chapter 37, "Configuring Alarms."
To configure a round-trip delay, take the following steps:
Step 1 Launch Property Editor for the agent, switch, or Frame Relay agent for which you want to define custom properties.
The Property Editor (Custom) window opens (Figure 12-1).
Step 2 Select the RT Delay radio button.
Step 3 Click Add to the right of the RT Delay list box.
The Add IP Ping Resource window opens (Figure 12-3).
Enter the following information:
Step 4 Click OK to write the round-trip delay configuration to the custom file of the agent, or click Cancel to exit the Add IP Ping Resource window without saving the round-trip delay configuration.
You can configure proxy SNMP resources on SwitchProbes that have the Resource Monitor option enabled. A proxy SNMP resource configures the agent to perform SNMP gets to retrieve the value a MIB II, RMON, RMON2 or private MIB object on a remote device. You can also set traps on any SNMP resource you are monitoring. To configure a proxy SNMP resource on a selected agent, take the following steps:
Step 1 Launch Configuration Manager by clicking the Config Manager icon in the TrafficDirector Admin level.
Step 2 Select the agent for which you want to configure a proxy SNMP resource.
Step 3 Select the Custom radio button.
Step 4 Click Property.
The Property Editor (Custom) window opens (Figure 12-1).
Step 5 In the Property Editor window, select the Proxy SNMP radio button.
Step 6 Click Add to the right of the Proxy SNMP list box.
The Add Proxy SNMP Resource window opens (Figure 12-4).
Step 7 Enter the information for the following fields:
Host--enter the name or IP address of the host you want the agent to monitor.
MIB--displays a list of MIBs for the agent you selected. Do one of the following:
When you select a MIB, the MIB field is filled in with the selected MIB, and the Variable Name and OID fields are updated with the objects in the selected MIB.
Step 8 Select the variable you want the agent to retrieve from the Variable Name and OID list box.
The selected OID is displayed in the Variable OID field.
Step 9 Enter the Variable Instance of the selected object you want to monitor. This usually corresponds to the interface number with which the MIB object you are monitoring is associated.
Step 10 In the Community field, enter the community string identifier for the SNMP host you want to monitor. Set this field to the value for the host you want. The default value is public.
Step 11 In the Poll Interval field, enter the number of seconds you want the agent to wait between samples, from 1 to 65535 seconds. The default is 60.
Step 12 Click OK to write the proxy SNMP resource configuration to the custom file of the selected agent or click Cancel to exit the Add Proxy SNMP Resource window without saving the configuration.
