I'm about to embark on an Opsview setup for a large company. I've been using Nagios since it was NetSaint, so I'm guessing I'll know my way around the inside of Opsview. However, I do have a few questions after looking over most of the documentation.
First, some background. I haven't upgraded Nagios in quite a while, I'm still running v.2.11, monitoring about 600 hosts and 1700 services. Most of these are routers and switches with a few WAPs and servers thrown in. I expect that the total number of devices will grow to about 800 by year end. I also run MRTG on a separate server monitoring about 200 of these devices. This may grow to about 300, but I expect that Opsview will replace this installation as well. I have two Datacenters, one in Colorado and another in New York, although currently the monitoring servers live in the Colorado DC. The servers are all Ubuntu running on VMware ESX. Other apps in use include NeDi, SmokePing, Weathermap, and two proprietary Netflow apps. According to the Opsview docs, it seems that distributed monitoring is recommended for anything over 250 devices. There is also a recommended hardware spec for maximum scalability. So, questions that I have right now: 1. Should go with the Distributed Monitoring or Maximum Scalability model? 2. Should I attempt to migrate from Nagios 2, or would it be best to build from scratch? 3. It sounds like the only benefit of Master/Slave Servers are failover? So far I've read that you cannot run active/active. Have I just not yet found the documentation on load distribution? 4. Both scenarios suggest a separate DB Server. Is this really necessary when running on VMware, since I can just grow the server resources when necessary? Finally, please feel free to offer any other advice that you think might be helpful before I dive into this. All input is greatly appreciated. Thanks!
