Don’t you mean `mkdir CA`instead of `make CA`?

I only list books in my post I have personally read and used and I have not had a chance to read yours (so far). Steve, glad for you to promote your book.

]]> Comment on MRTG 2.16 and High Speed Interfaces by Steve Shipway http://www.stanbarber.com/network-management/mrtg-2-16-and-high-speed-interfaces/comment-page-1#comment-5 Steve Shipway Thu, 13 May 2010 22:12:54 +0000 http://www.stanbarber.com/?p=440#comment-5 The counter rollover problem (which occurs at about 140Mbps when using the standard 5min polling cycle) is possibly the most frequently asked of MRTG problems. If your device doesn't support SNMPv2, then an alternative solution is to increase polling frequency to every minute, although that can be awkward and requires you to re-create your RRD or log file. You should also note that, if you're using a MRTG Target which is the sum of multiple counters, the rollover will hit much sooner and can cause really odd problems if you're using SNMPv1 counters.

I'll use the opportunity to plug my own book, "Using MRTG with RRDTool and Routers2" which can be bought online from <a href="http://www.steveshipway.org/book/" rel="nofollow">http://www.steveshipway.org/book/</a>. This covers a huge range of features and tips and techniques, including SNMPv3, the counter rollover problem, if-filter and much more. You mention a couple of books which have a section on MRTG.

I have a <a href="http://www.stanbarber.com/network-management/mrtg-2-16-and-high-speed-interfaces" rel="nofollow">posting about using SNMPv3</a> that shows the basics of how to get started using MRTG and Cisco IOS.

Currently I use it to pull data from our brocade switches to track read and write trends from our Hitachi SAN. I still use a fairly old version as was wondering if MRTG supports SNMP V3 authentication. I have used mrtg as well for several years.
