Configuring SNMP Monitors
Unit Measure – To define a Unit Measure, click the arrow to
select a unit measure (%, bytes, hours, minutes, seconds). You
can also type in a unit measure such as messages/minute. This
measure is a display string. It does not perform any data
translation.
Sample Every: – Specifies how often samples are
taken for this monitor. Refer to, ―Sample Every Settings,‖ later
in this chapter for a description of these settings.
Divide by Object ID Settings – Use this setting in conjunction
with the Object ID setting (above) to gather information that is
best expressed as a ration. The value retrieved by Object ID is
the dividend and the value retrieved by Divide by Object ID is the
divisor. (Object ID/Divide by Object ID).
Enable – Select this check box to enable this setting.
Object ID – Enter an object ID. For example, in the HOST-
RESOURCES MIB, disk size (hrStorageSize) and disk in use
(hrStorageUsed) are two different OIDs which, when
divided, give you the ration, or portion, of the disk that is in
use. Using this example, you could enter 25.2.3.1.6 as the
Object ID and 25.2.3.1.5 as the Divide By Object ID.
String Mappings – Displays the String Mappings dialog box for
specifying string mappings.
String Mappings – OneSight collects numeric performance
data. If you are measuring an SNMP object representing an
SNMP String datatype, it can be converted to a number for
use in OneSight by using the SNMP String Mappings field.
Simply specify a semicolon delimited mapping of Strings to
Integers. For example, ―false=0;true=1‖; will convert a
―false‖ reading to a 0 value in OneSight, and this will be
displayed in OneSight Status as ―false=0‖. If you only want
to display the string on the OneSight status page, use a colon,
rather than a semi-colon to delimit the values.
