IPSentry Monitoring Features - SNMP Get Request
||The IPSentry SNMP Monitor and Alert add-in provides you with the
ability to monitor SNMP compliant devices for management objects for
specific value thresholds.
The SNMP add-in allows you to setup multiple filters to be checked
during a cycle - if any one of the values queried match the
specified alerting filters, the add-in will return an alert state to
IPSentry thus causing any scheduled alerts to be triggered.
The add-in component contains a built-in MIB browser, MIB compiler,
and SNMP MIB walker allowing you to import vendor specific MIB
definitions and perform hierarchical viewing of the devices many
values for selection within the given filters.
Use of this add-in is generally utilized to test various aspects of
values returned from the queried device and compare to a
user-defined threshold. However, the add-in provides additional
monitoring functionality as a byproduct of it's usage.
Each of the above can be compared for positive or inverse matches.
- Ensure that the Device is responding to SNMP queries
- Ensure that the object being queried is accessible.
The values returned are then compared against your filters which may include whether or not:
- Value is Equal To a specific value.
- Value is Like a specific value (OCTET STRING)
- Value Contains a specified value (OCTET STRING)
- Value is less than a specified value
- Value has changed
- Value has increased
- Value has decreased
- Value is within a specified range
- Value has increased by more than a specified value.
- Value has decreased by more than a specified value.
- Value has changed by more than a specified value.
The SNMP Device and Trap alerting add-in is a dual function add-in
component with built-in MIB browser allowing you to walk the MIB on
an SNMP device with it's primary focus on the ability to query SNMP
compliant devices (V1, V2c, V3) for object values and evaluate them
against a user defined filter that ranges from octet matches and
contains, to value range thresholds, along with inverse and delta
You can specify the object ID directly if you know it or you can
import the MIB definitions, locate the object in the SNMP tree, walk
the host and select the object for filtering and alerting.
Within this add-in comes the SNMP trap alerting functionality for
use in the IPSentry Add-In Alert area. The IPSentry base application
includes an alerting mechanism for add-in components which extends
the base functionality considerably. IPSentry can send traps to a
trap host as a notification regarding the state of the entry being
monitoring along with a descriptive on the reason for the alert
allowing you to incorporate monitoring results into your existing
SNMP management systems.
