How do I add a user defined collector?

To add a user defined collector

User Defined SNMP Polling enables you to add user defined collectors that can be assigned to attributes.

A user defined collector is useful for instances when the Entuity collectors are not collecting data on certain device attributes that are available from the device vendor's MIB.

The Collectors tab on the User Defined Polling page has a table displaying any user defined collectors already in existence. The table has the following columns:

To add a user defined collector:

1. In the Main Menu, click Administration.
2. Click User Defined SNMP Polling. This will open the User Defined SNMP Polling page.
   
   
   
   
3. Using the Category and Object Type dropdown fields under the Collectors tab, you can check if there are any user defined collectors already in existence.
   1. In the Category dropdown field, choose from the following:
      1. User Defined Attributes
      2. Object Attributes
      3. Stream Attributes
   2. The Object Type dropdown field options will change dependent on your choice of Category.
      
      
      
      
4. To add a new user defined collector, click Add in the bottom left of the browser.
5. A window titled Please select an example device will open. Here, you can select the example device against which you want to test your new defined collector. Enter a search term and click Search to find an example device to use while defining the collector. Select your preferred device and click Next, or Cancel to exit.
6. In the User Defined Collector (User Defined Attribute) window, enter a name for the new attribute in the Name field. By default, Entuity adds the prefix "ud_". You can amend or delete this prefix. However, this prefix is helpful to distinguish between system collector and user defined collectors, for example in the case of a future Entuity upgrade that includes an collector with the same name as a user defined collector.
7. Enter a description for the attribute in the Description field.
8. Specify the StormWorks object type in the Object Type field.
9. Specify the user defined attribute name from which the user defined collector will be polling in the Attribute field.
10. Browse for the OID used to poll the attribute via Browse next to the OID field. This opens the MIB Browser window. Locate the OID and click OK.
11. Select the index in the Index dropdown field. If the attribute is a scalar, you can leave the Index set to None.
12. Specify the SNMP Version by clicking the appropriate radio button.
13. If some manipulation needs performing to format it properly, you can do this by modifying the Method statement. Do this by clicking Edit to open the Collector Method window. Edit the expression as you desire, clicking Test to test the expression, OK to save or Cancel to cancel.
14. Specify the Filter used to limit the collector to devices from a particular vendor. You can Edit this filter.
15. Specify the Priority of the collector. This is only relevant when multiple user defined collectors are applied to the same attribute. The collector with the highest priority setting will be applied first. By default, this is set to 1000. If you only have one collector assigned to an attribute, then you do not need to change this setting.
16. Select the Transform setting from the dropdown field, and click View to open the Transform Mapping window that shows you how the selected transform setting converts polled data into meaningful values. If you are creating a user defined collector for an OID that is not numerated, you can ignore the Transform setting.
17. At the bottom of the window, click OK to save your user defined collector, Back to return to the search example device window, otherwise click Cancel. If you save the collector, it will take effect the next time the specified attribute is polled.
