Gold in ovtopodump

By simply typing:

					ovtopodump -Lr > report_name
				

you can get a very useful one-line summary for each device in the NNM database. On a UNIX system you can pipe the output of the ovtopodump command into one or more filters (such as sort) to tailor the output for some specific purpose. For example, suppose you want to find out which devices in the management domain don’t have DNS entries, simply type:

					ovtopodump -Lr | sort > report_name
				

and examine the entries near the top of the sorted list. The numeric selection names percolate to the top of the list, neatly identifying the devices without DNS entries.

Here is another useful one-liner:

					ovtopodump -o | grep “.1.3.6.1.4.1”
				

This prints a neat report of all discovered SNMP-manageable devices and their corresponding sysObjectID values.
