How many DNS queries

Is there any way to see how many queries come into our external DNS server? In looking at DNS providers, most of them base pricing on number of queries per month so I just wanted to see if you had any idea/way of gathering that data? A rough ballpark figure would even work.

Our DNS server is RHEL4.

Many thanks

Try nscd --help To get the option that reports cache information.

The name service daemon keeps track of catch hits and fails.
