OneSight Administrator Guide

Configuring SNMP Monitors
If you neglect to provide a mapping for a specific string,
OneSight will consider this a Sample Failure, and report the
String that was returned. String Mappings can also be used to
translate a number to a String for display in OneSight Status.
This is helpful when numbers represent an objects state.
Note that string matching is case-insensitive and data that has
a colon cannot be used in string mapping.
Test – When you add or modify a monitor, you can test General
settings to determine if they are set appropriately. After clicking
the Test button, you will see messages in the status window as
the test runs and when the test completes.
7. Click the arrow next to the Metric box to select from the list of
common SNMP metrics (for example, HOST-RESOURCES-MIB
% Disk Space Used). The list includes metrics for a variety of
SNMP MIBs. If you’re using a metric in the HOST-RESOURCES-
MIB group, the machine you’re monitoring must have SNMP
and the Host Resources MIB enabled.
When you select one of these objects, the appropriate object
information is automatically supplied. In some cases, the
settings allow you to supply an additional setting, such as a
Search for String.
If the metric you want to monitor is not in this list, select the
option from the Metric list and click MIB Browser to
find it. In the MIB Browser, select the metric you want to
monitor, verify that it is accessible by clicking Go. When you
exit the MIB Browser, you can save the settings to the Object ID
field.
8. If necessary, type in the Search for String. This is the string
OneSight will search for in the OID column specified. In the
case of Disk: Space in Use, the default, /usr, may be
appropriate.
