SNMP Log

NAVIGATION  Monitor > SNMP Monitoring > SNMP Log

The SNMP Log page displays SNMP log data of MIB objects in a SNMP Set in chart or table formats. 

  1. Click a machine ID link to list all SNMP devices associated with a machine ID.
  2. Click the IP address or name of an SNMP device to display all SNMP sets and MIB objects assigned to the SNMP device.
  3. Click the expand icon to display the collection and threshold settings for a MIB object.
  4. Click the down arrow icon to display MIB object log data in chart or table formats.
  5. Click the Bar Chart or Table radio options to select the display format for log data.

SNMP monitor objects can contain multiple instances and be viewed together within one chart or table.  For example, a network switch may have 12 ports. Each is an instance and can contain log data. All 12 instances can be combined in one chart or table. SNMP bar charts are in 3D format to allow for multiple instance viewing.

Machine ID.Group ID / SNMP Devices

All machines assigned to SNMP monitoring and currently matching the Machine ID / Group ID filter are displayed. Clicking the machine ID link displays all SNMP devices associated with the machine ID. Click the SNMP device link to display all MIB objects associated with the SNMP device.

View

Click the View link to display log data for a MIB object in a chart or table.

Remove

Click Remove to remove log data from a chart or table.

View All

If the SNMP monitor object has multiple instances, clicking the View All link displays all data for every instance.

Remove All

If the SNMP monitor object has multiple instances, clicking the Remove All link removes all data displayed for each instance.

Monitor Set Name

The name of the SNMP set the MIB object belongs to.

Get Object Name

The name of the MIB object used to monitor the SNMP device.

Description

The description of MIB object in the SNMP set.

Bar Chart / Table

Select the Bar Chart or Table radio button to display data in either format.

  • A bar chart displays the last 2000 data points at the sample interval rate. The background of the chart displays in red for alarm threshold, yellow for warning threshold and green for no alarm.
  • Table log data displays the most current values first and displays alarm and warning icons on log data that falls within these thresholds. See Define SNMP Set for more information.

Display Last

Bar charts display log data for the last number of intervals selected. For example, if you select Display Last 500 minutes, each bar in the chart represents 1 minute.

Save View

You can save custom views for each MIB object. The next time this MIB object is selected the saved information is loaded.

Log rows per Page

These fields only display in Table format. Select the number of rows to display per page.

Display Value Over / Under Value

These fields only display in Table format. Filter the table rows displayed by filtering log data that is over or under the value specified.

Refresh

Click the refresh button to display the most current log data.

If your monitor doesn't show any log values, verify the following.

  1. If there are no values returned, check the collection threshold for MIB objects in SNMP sets. If no values on the monitored device meet the collection threshold they are not included in the SNMP log.
  2. The log value sample interval is determined by the total number of SNMPGet commands retrieving information from SNMP devices to the agent of the machine ID. The more SNMPGet commands the larger the sample interval. Check all SNMP devices associated with a machine ID. If some SNMPGet commands are returning values but others are not, the SNMPGet commands for the failed requests are not compatible.

If a monitor isn't responding, the log displays the message Monitor Not Responding. The SNMPGet command is incompatible with the device.
