Creating and adding multiple SNMP collectors

How to create an SNMP collector.

About this task

To add an SNMP collector:

Procedure

  1. In the Logical view, right-click the DataChannel x folder.

    The pop-up menu lists the following options:

    • Add Collector SNMP - Creates an SNMP collector.
    • Add Collector UBA - Creates a UBA collector.
    • Add Collector BCOL - Creates a BCOL collector. This collector type is used in custom technology packs. DataMart must be added to the topology before a BCOL collector can be added.

    Select Add Collector SNMP. The Configure Collector window is displayed.

  2. Using the drop-down list of available hosts on the Configure Collector window, select the computer that hosts the collector . (for example, corinth)
  3. Accept the default collector number (for example, 1).

    The default collector number is seen in the collector number property. However, you need not accept the collector number. You can edit the collector number and port number as per your requirement. The collector number ranges from 1-999 of which 500 and 501 are restricted for other purpose. The port number ranges from 3002 to 3999 and 3003 by default is the watched process.

  4. Repeat the steps from 2 to 4 for as many SNMP collectors you want to add. Ensure that the collector number and port number should be unique for all the SNMP Collectors.
  5. Click Finish.

    The maximum number of SNMP components (SNMP Collector and SNMP Spare) on a host is 16.

    The Topology Editor displays the new collector under the DataChannel x folder in the Logical view.

    Note: The port number property is not editable in the Topology Editor once it is selected in the Configure Collector Window. If you want to change the port number, you must remove the collector from the topology by right-clicking on it and choosing remove. Then add the collector back and edit the port in the Configure Collector Window.
  6. Highlight the collector to view its properties. The Topology Editor displays both the SNMP collector core parameters and the SNMP technology pack-specific parameters. The core parameters are configured with all SNMP technology packs. You can specify an alternate installation user for the SNMP collector by changing the values of the pv_user, pv_user_group and pv_user_password properties in the Advanced Properties tab. Review the values for the parameters to make sure they are valid.
    Important: Irrespective of the number of collectors that you add, the directory is created only on /opt/dataload.
    Note: For information about the core parameters, see Properties Reference.

Results

The collector has two components:

  • Complex Metric Engine x - Perform calculations on the collected data.
  • File Transfer Engine (FTE) x - Transfers files from the collector's output directories and places them in the input directory of the CME.

The FTE writes data to the file /var/adm/wtmpx on each system that hosts a collector. As part of routine maintenance, check the size of this file to prevent it from growing too large.

Note: Your Solaris version can be configured with strict access default settings for secure environments. Strict FTP access settings might interfere with automatic transfers between a DataChannel subchannel and the DataLoad server. Check for FTP lockouts in /etc/ftpd/ftpusers, and check for strict FTP rules in /etc/ftpd/ftpaccess.
Note: The Topology Editor includes the channel and collector numbers in the element names. For example, DataChannel 1 could have Collector SNMP 1.1, with Complex Metric Engine 1.1. and File Transfer Engine 1.1.
