Monitoring SNMP Agent |
|
The Simple Network Management Protocol (SNMP) is an Internet standard that allows management data on different network devices to be read and write by an application. You can use IPSpotter to view and write SNMP objects on any device that implements an SNMP agent.
SNMP agent must be installed and enabled on any devices from which you want to receive SNMP information. Windows 95/98/me/NT/2000/XP provide an SNMP agent. Network systems manufacturers provide an SNMP agent for their routers, hubs, and other network boxes. Follow the provided instruction to install SNMP agent. For Windows, you can get instructions by selecting "Start->Help", then typing "snmp agent".
IPSpotter uses a reference file, mib.txt to refer to MIB identifiers. The reference file is used by IPSpotter to display the MIB object tree when you browse for an object name/identifier using the SNMP Browser. As shipped with IPSpotter, this reference file contains the SNMP objects defined in the MIB-II standard (see RFC1213).If your network includes devices from a vendor who also provides RFC-compliant MIB files, you can update mib.txt to include the MIB identifiers from the vendor’s file. To do this, you should first make sure that the root identifier in the vendor's file can be found in MIB.txt, then you just append the vendor's file to mix.txt (note: you should save a copy of the original mix.txt).
Setting Up Notification for SNMP Objects
To set notifications for a device, double click on the device to pop up the property dialog or right click the icon, then select Propertis... from the context menu. In the SNMP page, you will see a list of SNMP objects, which are relative to TCP. You can add more objects by modifing the snmpconfig.ini file or click on the Add SNMP Object button. If you want to monitor a SNMP object, check the object, then highlight the object and click on Set Notification. You can set notifications based three different type values:
IPSpotter provides SNMP Interface, MIB Browser, and SNMP Command to help you monitor SNMP objects:
1. | SNMP Interface: Select SNMP Interface from
the Action menu to run SNMP Interface. It displays hardware status for a
device based on SNMP Objects in the "Interface" group as shown in the following picture:
![]() The colors of hardware items represent the status of hardware: |
2. | Mib Browser: To run Mib Browser, Select Mib Browser from
the Action menu. Mib Browser consists of three pans. The left pan shows the MIB tree based on mib.txt file; the right pan
on top, shows the selected tree item's child item or its SNMP values; while the right pan on bottom shows comments on the selected SNMP
object. There are three kinds of icons shown on the top right pan:
![]() ![]() ![]() |
3. | SNMP Command: To run SNMP Command, Select SNMP Command from the Action menu. You can issue Get or GetNext commands with a single or a group of SNMP objects. |
