Using MonitorMagic
Snmp get monitor - Object identifiers and MIB's
A Snmp get monitor contains the specification of a SNMP host, community and up to 8 object
identifiers. The object identifiers specify the data that must be collected from the SNMP host. The
object identifiers can be found in the Management Information Base (MIB) that is supported by
the SNMP host. Note that the MIB is specific for the SNMP host and that the MIB complies to the
SNMP standard.
In order to be able to specify a Snmp get monitor, you need to know the object identifier(s) you
want to collect data for. To know the object identifier, you need to have the MIB file in text format
available, or you can examine the SNMP host by querying all the data with MonitorMagic. Note
that with MonitorMagic you cannot import the MIB file. If you would like to see this feature
implemented, please send an E-mail message to support@tools4ever.com.
For each Snmp get monitor 8 object identifiers can be specified. Since an object identifier is not
very descriptive, you can specify an description for each object identifier. The description can be
shown in the various windows of MonitorMagic. For each object identifier, the Snmp get monitor
has a data field to contain the actual data.
To learn more about SNMP, you can read the following book:
The Simple Book
An Introduction to Internet Management
by Marshall T. Rose, ISBN 0-13-177254-6, Prentice-Hall, Inc.
or you can get more information from a number of web sites, for instance

To specify a Snmp get monitor, you can use the following guidelines to minimize the effort
involved:
Required information
TCP/IP address of SNMP host and community name (public?) of the SNMP agent
supported by the SNMP host
Object identifier(s) of the information you want to collect, example 1.3.6.2.1.3.2.4.5.
Note that you need to have the Microsoft SNMP service installed and running to
use the Snmp get monitor.
Object identifiers
If you don't know the object identifier, you can use MonitorMagic to find the object
identifier by querying all information from the SNMP agent. See Snmp get monitor -
Getting all data for more information.
Object identifiers are described in the Management Information Base that is supported by
the SNMP agent. If you have a (printed) text file of the MIB, you can find the object
identifier and test it with MonitorMagic. See Snmp get monitor - object identifier
specification for more information.
You can use the Internet to find a mib file of a certain device. For example, the Internet
site http://www.mibcentral.com contains a library of mib files for many systems of various
manufactures.
