Slicehost 上的 Ubuntu 8.10 监控软件？
我是服务器管理新手，我正在寻找一些选项来监视 slicehost 上的切片（ruby on Rails 站点）。理想情况下，状态和负载的实时视图会很棒。
有什么建议吗？
I am new to server administration and I am looking for some options for monitoring my slice (ruby on rails site) on slicehost. Ideally, a live view of status and loads would be great.
Any suggestions?

Slicehost 和Scout
我们一直在使用 scout 来监控我们的 Rails 应用程序及其在 slicehost 上的切片。效果很好，而且安装起来非常非常容易。对我来说，主要特点是（相当）广泛的监控代理和低成本。
Scout 和 NewRelic
为了回答 ChrisH 的评论，我在使用 Scout 几个月后与 NewRelic 进行了比较。
NewRelic 提供与 Scout 相同的信息，但格式更好。
NewRelic 能够监控分布在多个主机上的应用程序 - 这是 Scout 无法做到的。然而，当垂直缩放非常容易时，您可能不需要水平缩放 Slicehost。
Scout 免费提供更多监控选项，第一层商业产品更便宜（15 美元 vs 40 美元），但它们限制了您可以存储的历史数据量。
Scout 似乎有更广泛的监控选项 - 他们有一个开放的代理 API，这使得开发新代理变得简单 - 所以你可以获得诸如内存缓存监控之类的东西。
我不喜欢 Scout 的一件事是他们不管理异常。不确定 New Relic 是否这样做，但这似乎是监控产品中的一个巨大漏洞

Slicehost & Scout
We've been using scout to monitor our Rails apps and their slices on slicehost. Works pretty well and is very, very easy to install. Key features for me are the (reasonably) wide set of monitoring agents and the low cost.
Scout and NewRelic
To answer ChrisH's comment I did a comparison with NewRelic after having used Scout for a few months.
NewRelic presents the same information as Scout but in a nicer format.
NewRelic is able to monitor an application which has been split over multiple hosts - not something that Scout can do. However you probably don't need to scale Slicehost horizontally when it is so easy to scale vertically.
Scout gives more monitoring options for free and the first tier commercial offering is cheaper ($15 v $40) but they limit the amount of historical data you can store.
Scout seems to have a wider set of monitoring options - they have an open agent api which makes it simple to develop new agents - so you can get things like memcache monitoring.
One thing I don't like about Scout is that they don't manage exceptions. Not sure if New Relic does this but it seems like a huge hole in the monitoring offering

如果你有 iPhone，你应该看看 iStat。有一个开源版本的监控守护进程可以在 Ubuntu 上运行良好。
If you have an iPhone, you should take a look at iStat. There's an open source version of the monitoring daemon that runs nicely on Ubuntu.
