This again leads to qustion - do you have any problems? Now my plan is to plot the graph where i can see number of concurrent session for incoming queries, and the total number of sessions, also i get to know any sudden increase will generate alert. note that DNS has no sessions. The only behaviour similar to this is number of concurrent TCP queries. But a small server can handle thousands of queries per seconds without problems. Is there systems do you recommend. i believe we can achieve this cacti. I can recommend cacti. -- Matus UHLAR - fantomas, uh...@fantomas.sk ; http://www.fantomas.sk/ Warning: I wish NOT to receive e-mail advertising to this address.

RE: concurrent-session
It does depend somewhat on what you mean by concurrent sessions. Do you mean incoming queries? Do you mean incoming zone transfers? Do you mean outgoing zone transfers? Each is a different tunable. Ultimately, system-wide file descriptor limits do come in to play, but the zone transfers listed above is the only thing with defaults.
