SNMP - User Experience monitor
The lightweight SNMP monitor verifies that an SNMP agent can respond to an information request in a timely manner.
ipMonitor measures round trip time by sending a request for a fixed piece of information (such as sysUpTime oid 18.104.22.168.22.214.171.124.0) to the specified SNMP agent and waits for a valid response. The Monitor test will pass if the monitor receives a valid response within the required timeout period.
The SNMP monitor verifies that:
- The target SNMP agent is running and able to respond.
- The response makes the complete round trip within a specific number of seconds.
To monitor the end-to-end performance of your SNMP-enabled devices or applications from the end-user perspective, use the SNMP - User Experience Monitor to perform the following procedure:
- Retrieve a Numeric or Textual value from a SNMP agent
- Test the value against the rules you define
- Perform delta comparisons
SNMP Agent Security
A commonly-used SNMP security feature requires you to specify which IP addresses can communicate with the SNMP agent. If this security feature is enabled on the SNMP agent you want to monitor, configure this feature to include the IP address of the ipMonitor host machine.
Another commonly-used SNMP security feature requires you to specify which IP addresses can communicate with the SNMP agent. If this security feature is enabled on the SNMP agent you want to monitor, configure this feature to include the IP address of the ipMonitor host machine.
SNMP - User Experience wizard
The SNMP - User Experience monitor wizard help you configure an SNMP - User Experience monitor with the least amount of initial input. Using the SNMP - User Experience Monitor wizard, you can connect to an SNMP-enabled device and retrieve a set of SNMP-data without requiring an exact OID. Additionally, you can test all parameters you enter along the way to make sure that the monitor will operate as expected before you move to a production environment.
The following sections describe the screens that display in the wizard.
Step 1: Select SNMP device and scan parameters
The following example illustrates the configuration process for creating an SNMP - User Experience monitor to monitor the temperature reported by an APC environment probe:
- Log in to the ipMonitor Administration interface.
- Click Monitors and select Add a Monitor.
Select the SNMP - User Experience (Wizard) from the SNMP category.
You can also select the SNMP wizard from the Configuration tab.
Step 2: Select an SNMP object to monitor
Scrp;; through the returned set of objects and their corresponding values, and then click Select to select the object you want to monitor.
Step 3: Provide SNMP object comparison rules
Examine the details of the selected object. This information is ideal for determining the type analysis you can perform in Analysis of Test Results section.
The type of data supported by the selected OID determines the possible methods of analysis. Use the object information outlined above to set the comparison rules and ensure the monitor will pass when enabled.
Step 4: Name and configure your SNMP User Experience monitor
Enter a descriptive name for the new monitor using up to 64-characters. The monitor name will display in the Monitors List, Monitor Status, Reports and Logs pages. Because ipMonitor does not use the Name field to internally identify the monitor, you can change the monitor name at any time without losing your data.
Parent Group - Create in Existing Group
When enabled, select an existing groups from the Selected Group list. The new monitor will automatically be added to this group.
Parent Group - Create New Group
When enabled, type the name of the new group in the Group Name field. The new monitor will automatically be added to this group.
Create Monitor Enabled
After you create the monitor, ipMonitor tests the target server or device using your configured settings. This option is enabled by default.
Store Monitor Statistics for Recent Activity and Historical Reports
ipMonitor will begin to record test results, which are used to generate Recent Activity and Historical reports. This option is disabled by default.
Click Finish to exit the wizard and access the new monitor in edit mode. You can make any final modifications to the monitor (including the timing and notification parameters) in this mode.
After you complete this step, click OK. The new monitor displays within the Monitors List.
