Hello! This is my first message to NANOG's mailing list. I hope someone can help me. I was wondering which tool(s) can I use to measure the performance of my 3 DNS servers (1 primary, 1 secondary, 1 solely cacheDNS)? From the stats I would like to know if my DNS server is serving as it should be or if any of it's options are set inappropriately and others alike. I looked for a while but could not find any. Any help would be highly appreciated. I am running bind9 on UNIX platform. Question 2) I would also like to know how can I graph my DNS logs? And how can I integrate it to my CACTI server as well? I couldn't find any suitable plugin. Any suggestion? -- -- Best Regards, *Zayed Mahmud* *Senior Core & IP Network Team,* *Banglalion Communications Limited, Bangladesh.*
