There is a bunch of Linux Server Monitoring software available. The problem is sifting through it all. The first thing to do is identify what it is you want to monitor then you can find what software will work best for your needs. As far as system monitoring goes there is old school and new school. Any combination of tools could be used and there are also a number of ways you can home brew some monitoring solutions. Click for the large version of the Linux Server Monitoring Image. (Read on …)
A friend sent me an article from the register on VoIP today (http://www.theregister.co.uk/2008/08/12/iphone_voip/)
Now, it states that voip for apps on the iPhone could only be used if cost is an issue. I think that voip on phones is a good idea, even if voip is not on phones it can still be implemented very well. They state that 35 GBP will get you 10 hours of talk time, while this seems like a lot, how much international time is that? With an Asterisk box one can easily set up a voip trunk that would allow its owner to dial in and call internationally for the cell cost of local minutes and the cost of the voip provider. This could potentially save a lot of money.
With every plan, you get unlimited data. If you only get 450 minutes with your plan, you could use a native application with unlimited data to talk more. I’ve also thought about creating “push-to-talk” PTT, sort of like the other walkie talkie services offered. If you could do this with Voip, it wouldn’t be limited to cell phones like the other major services are, people at their laptops or desktops could also participate where cell phone coverage isn’t available.
I’d like to see more people take advantage of Asterisk and start creating innovative phone services. I don’t think that having an application that utilizes VoIP would necessarily be a bad thing. I actually think that VoIP on the iPhone is a good idea and will continue to do so until it starts interfering with the providers income and in result interfering my bill.
