    Turning SNMP Data Collection Off and On

    Network performance can be adversely affected by the amount of traffic generated by SNMP data collection. For this reason, SNMP service in Junos Space Network Management Platform is not started by default.

    Junos Space Network Management Platform Network Monitoring is always turned on for all devices by default. The ability to turn on data collection is controlled by the Monitor_SNMP surveillance category. However, turning on data collection increases the amount of SNMP traffic. If the surveillance category is removed from a device, data collection is turned off.

    To turn SNMP data collection off or on for a device:

    1. In the Network Monitoring workspace, display the Node List page and click the node name.

      The resulting page displays detailed information about the device.

      For example, you can select Network Monitoring > Node List or you can select Network Monitoring > Search and click All nodes in the Search for Nodes section of the Search page to display the Node List page.

    2. In the Surveillance Category Memberships title bar, click Edit.

      The Edit surveillance categories on node name page appears.

    3. Select the Monitor_SNMP category from the Categories On Node list on the right.

      If this category is not in the list on the right, then SNMP data collection is already turned off.

    4. Click Remove between the two lists.

      The removed category appears in the list of Available Categories on the left.

    To turn on data collection for selected devices, reverse the process described here.

    Note: The Network Monitoring functionality performs SNMP data collection by default only on primary interfaces. If you want to change this, instead of manually selecting the interfaces to be monitored from the GUI, you can set data collection for all interfaces by default by modifying the SNMP collection to set the SNMP Storage Flag to all (see Managing SNMP Collections). For information on the procedure to select other interfaces and the distinction between primary and secondary interfaces, see Configuring SNMP Data Collection per Interface.
