Input: java sendtrap -p 4001 -c public -m mibs/RFC-1213 192.168.1.1
.1.3.6.1.2.1.1.1.0 192.168.1.1 0 0 1000 .1.3.6.1.2.1.1.1.0 xyz
This matches the Match Criteria of the Trap Parser if it is:
• Generic Type - 0
• Specific Type - 0
• Enterprise oid - .1.3.1.6.1.2.1.1.1.0
• Oid - .1.3.6.1.2.1.1.1.0
• Value - xyz
• Agent - 192.168.1.1
• Port - 4001
The TrapParser gets trap from any trap originator and parses the trap event.
11.9 Graphs
The Mib Browser enables a real-time plotting of SNMP data on a graph. Currently, two types of graph are supported: line
graph and bar graph. The SNMP data to be polled should be of integer or unsigned integer data type. Typically, the values
that are plotted are of type Counter, Gauge, or Timeticks.
The steps listed below should be followed for plotting the SNMP data in the graph:
1. Ensure the appropriate MIBs have been loaded.
2. Specify the proper agent host name or IP address in the host field of the Mib Browser.
3. Specify a valid variable. The variable needs to be an integer or unsigned integer (Counter, Gauge or Timeticks). The vari-
able can be chosen by browsing the MIB in the MibTree.
After selecting the variable from the MibTree, click the GRAPH icon or select the menu item Line Graph or Bar Graph from
the View menu. This brings an automatically updated graph, showing the results of periodically polling the specified agent
for the specified OID. By default, polling for the graph is done every 5 seconds.
The following options can be configured for the graph:
• Polling Interval - Default value is 5 seconds: editable, can be given any value.
• Average over Interval - By default, the graph shows the actual values of a variable for different hosts. In other words, the
values of the specified OID are plotted for different hosts for the given polling interval. This option is used to take the
average of the values at a given polling interval for plotting the graph.
• X axis scale - Allows to set the X axis scale; the minimum is 300 secs.
• Show Absolute Time - If selected, it shows the time in hrs:secs otherwise in seconds.
• Max X value - Allows to set the maximum time the graph can plot. The default maximum value is 3600 secs.
• Show Polled Values - If selected, it shows all the polled values in a particular time period. By default, it is disabled.
• Log File Name - The filename for the log file can be set here. By default, the log filename is graph.txt. If Log Polled Val-
ues is selected, all the polled values are logged in this file. This option is not enabled when the MibBrowser runs as an
applet because of security restrictions.
• Log Polled Values - If selected, it logs the polled values. By default, it is disabled.
• Show absolute counters - To enable the plotting of the absolute value. By default, the graph plots only the difference
between the two values.
• The Stop button can be used to stop the polling of the variable. The Restart button can be used to restart the polling. The
Close button is used to close the graph window.
