The main things you will not get from Nagios that you almost always get with Tivoli: * High recurring licensing fees * On-site Tivoli consultants :) Nagios does not give you "out of the box" the visualization dashboards that Tivoli has but with Nagviz you can you make very nice graphical dashboards at a much much lower cost to your company. Nagios also does not do auto-discovery out of the box but there are projects that give you that capabililty - again at a much lower cost. Distributed Nagios - there are a few choices, you will need to take the time to evaluate them all and choose the right one for you, but again, cost will be lower than Tivoli. The team I am on is building out a distributed architecture for Nagios based on our unique requirements - self service model where many SAs can all change configs on their schedule without our intervention, clustering, fast redistribution of hosts/services across pollers, centralized transparent (to the end user) command and control across all pollers. We are using some existing tools (Nagios and Merlin) and 4 developers and even then the TCO and maintenance cost will be magnitudes of order cheaper than Tivoli with much more functionality than most Tivoli shops offer. A polling model always has some challenges when it comes to scaling big but compared to Tivoli I think you will find Nagios to be both a lot more fun, a lot more flexible, a lot better fit, and, if politics don't interfere, your management should be much more happy with a fixed cost development price tag than the high $$ open ended maintenance costs of a commercial product like Tivoli. - Max <div class="gmail_quote">On Fri, Jun 11, 2010 at 10:19 AM, steve f <<a href="mailto:a31modela@hotmail.com">a31modela@hotmail.com</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> <div> Hello All, I am currently looking for an alternative to using Tivoli , TEC & postemsg for a rather large ( 6000 + ) remote environment. I have had great success with Nagios in my small local/remote test environment and the obvious cost savings without having TEC anymore is huge. Can I use the existing postemsg tests that are running on the boxes and via I guess External Commands have Nagios process the messages? For those familiar with both Tivoli & Nagios, Is there anything that Tivoli gives me that I cant do with Nagios? I don't see it if there is.
