SNMP Sets

Monitor > SNMP Sets

SNMP Sets adds, imports or modifies a SNMP set. A SNMP set is a set of MIB objects used to monitor the performance of SNMP enabled network devices. The SNMP protocol is used because an agent cannot be installed on the device. You can assign alarm thresholds to any performance object in a SNMP set. If you apply the SNMP set to a device, you can be notified if the alarm threshold is exceeded. The following methods can be used to configure and assign SNMP sets to machine IDs.

  • SNMP quick sets - Creates and assigns an device-specific SNMP set based on the objects discovered on that device during a LAN Watch. SNMP quick sets are the easiest method of implementing SNMP monitoring on a device.
  • SNMP standard sets - These are usually generic SNMP sets that are maintained and applied to multiple devices. A quick set, once created, can be maintained as a standard set.
  • SNMP individualized sets - This is a standard SNMP set that is applied to an individual device and then customized manually.
  • SNMP auto learn - This is a standard SNMP set that is applied to an individual device and then adjusted automatically using auto learn.
  • SNMP types - This is a method of assigning standard SNMP sets to devices automatically, based on the SNMP type determined during a LAN Watch.

Typically the following procedure is used to configure and apply SNMP sets to devices.

  1. Discover SNMP devices using Monitor > LAN Watch.
  2. Assign SNMP sets to discovered devices using Monitor > Assign SNMP. This can include quick, standard, individualized or auto learn SNMP sets.
  3. Display SNMP alarms using Monitor > SNMP Log or Dashboard List.

The following additional SNMP functions are available and can be used in any order.

  • Optionally review the list of all imported SNMP objects using Monitor > Monitor Lists.
  • Optionally maintain SNMP sets using Monitor > SNMP Sets.
  • Optionally add an SNMP object using Monitor > Add SNMP Object.
  • Optionally assign a SNMP type to an SNMP device manually using Monitor > SNMP Type.
  • Optionally write values to SNMP devices using Monitor > Set SNMP Values.

Note: Not all SNMP Sets may be available for editing, since the creator of a SNMP Set may only have shared the use of the set but not the display or editing of the set.

Note: Certain command line functions from the Net-SNMP suite of applications are used to implement SNMP v1 and SNMP v2c retrieval of information from SNMP capable devices in accordance with all pertinent copyright requirements.

Select Page

When more rows of data are selected than can be displayed on a single page, click the and buttons to display the previous and next page. The drop down list alphabetically lists the first record of each page of data.

Add

Click Add to open a form that asks the user to:

  1. Monitor Set Name - Name the new SNMP set.
  2. Monitor Set Description - Optionally describe the new SNMP set.
  3. Automatic deployment to - Select a category of SNMP devices. If a LAN Watch detects this type of SNMP device the system automatically begins monitoring the SNMP device using this SNMP set.
  4. Group Alarm Column - Select a group alarm column. User defined group alarm column names are maintained using the Monitor Lists page. Group alarms display on the Dashboard List page.

Import

Click Import to upload a SNMP set XML file to your server. SNMP sets can be exported using Define SNMP Sets.

Edit

Click Edit to display Define SNMP Set and edit a monitor set.
