保持你公司的关键业务的Linux系统顺利运行是一个挑战。当性能瓶颈和调整机会出现时,已经太晚了--你的用户已经被你缓慢或无反应的网站或应用程序所影响。这使你的用户感到愤怒,并使你付出代价。

你的Linux系统会产生数据--这些数据对你的系统管理职责来说是非常有价值的。这些数据可以帮助消除那些瓶颈,避免停机时间。数据可以帮助你做出关于负载分配的决定,以确保系统更有效地运行。数据可以帮助你为意外的流量高峰做更好的准备,并帮助你利用过去的数据做出有关未来的更明智的决定。 我们着手建立一个分析工具来解决这个问题。其结果是:Longview。

介绍长安街

longview1长垣县 是一个新的统计数据收集和图形服务。它记录了你所有的系统级指标,并以醒目的可缩放图表显示。Longview使你很容易即时了解你的服务器的资源使用情况,并发现CPU、内存、网络和进程等方面的趋势。

你可以获得整个机群的鸟瞰图,或者聚焦于一个特定的服务器,以显示有关运行进程、监听服务、活动连接和可用更新的详细信息。它可以让你监控磁盘I/O和网络流量以及更多。而且,这一切看起来绝对令人惊讶

安装

Longview代理是开源的,可以安装在任何支持的Linux系统上--它不需要是Linode。支持的发行版有:Debian,Ubuntu,CentOS, 和Fedora。还有一个为酷孩子准备的客户端的tarball分布。

自动安装很简单--只需登录Linode管理器,点击Longview标签,点击 "添加客户端",然后复制/粘贴单行安装命令到任何支持的Linux系统。不一会儿,你的图表就会开始填充。longview-agent使用你的系统的软件包管理工具,所以以后更新和/或删除它很容易。

它的成本是多少?

基本的Longview是完全免费的,包括5分钟的数据解析和30分钟的数据保留。

将你的账户升级到Longview Pro,你就可以获得每分钟的分辨率和无限的数据保留,并且可以成包使用:

  • 多达3个服务器:20美元/月
  • 多达10个服务器:40美元/月
  • 多达40台服务器:100美元/月
  • 多达100台服务器:200美元/月

    Since this works on non-linode systems, does that mean I can install this on my Raspberry Pi at home?

  2. Author Photo

    Yes, we just rolled support for ARM systems. Please give it a shot!

    Completely replaced Copperegg with this monitoring (and I happen to like it a lot better). Thanks Linode. 🙂

    This is nice and cool and certainly useful but I’m a bit disappointed by the price structure, it’s a bit steep to have to pay US$20 if you have only 1 or 2 instances.
    The free version is barely enough to wet your appetite: 30 minutes of retention is really not much to make it useful, by the time you notice something strange has happened, it’s already gone.

    Not trying to be difficult — but why would I use Longview at the free level when it only provides 30 minutes of data when I could use New Relic (obviously the biggest competitor here) at the free level they provide 24 hours of data? I don’t follow how 30 minutes of historical data is really going to be all that convincing at the free level.

    Ubuntu 13.04 is still not supported? Installed without any errors, but don’t see any data.

    Setting up linode-longview (1.0.0) …
    * Starting Longview Agent longview [ OK ]
    System start/stop links for /etc/init.d/longview already exist.

    @Endijs Lisovskis: It is supported! Please open up a ticket if you’re having problems and we’ll get right on it.

    Longview Pro is priced very competitively. Look around.

    We had to start somewhere with Longview free, and this is what we came up with. It may (or may not) change in the future, but at least starting low gives us the opportunity increase what you get with the free version.

    Regardless, this is just version 1.0, and many additional features are planned.

    @xxdesmus Good question. Would like to see some case studies too.

  10. Author Photo

    How does this affect Longview Pro beta users?

  11. Author Photo

    I just installed Longview Agent to my local ubuntu server. It works very well.
    One for a Linode still has no restriction. Switch to free soon?
    And any plan to open-source Longview Server as well as Agent?

  12. Author Photo

    I was just curious if you guys had built this with accessibility in mind. For example for us blind folks who can’t see graphs, seeing a text version of the stats would be awesome, maybe with some statistics to go along with it.

  13. Author Photo

    Any chance you are going to revisit Linode Managed pricing to do a similar kind of pricing structure? We are still interested, but unfortunately not at anywhere near the $1600-2000 per month it’s going to cost us based on having 16-20 smallish nodes.

  14. Author Photo

    I have one linode instance,the free version is enough for me.

  15. Author Photo

    I agree with @xxdesmus. The 30-minute retention on the free version doesn’t make any sense. It’s gone by the time you’re able to view it. Why putting in effort to implement it, if the metrics are barely there.

    I think 24 hours of retention is reasonable to do with free. For people with on 1-2 nodes, it’s good enough. For bigger customers it’s a stepping stone to see if it fits the needs and upgrade instantly to pro.

  16. Author Photo

    Any chance for some docs on how the agent interacts with the dashboard, and what exactly thr dashboard does with this data?

  17. Author Photo

    I installed it. Tried it. and… another me too behind @xxdesmus … 30-min is useless to help understand if Longview provides me the view of my system(s) I need in order to evaluate if it would be worth upgrading to the pro version.

    I installed Longview and it looked nice but what can one do with 30 minutes? As per the suggestion in the comments above, I installed New Relic’s PHP and OS agents and now I have 24 hour retention. Let’s face it, we’re not all running big companies off our Linodes.

    I guess Longview makes sense if you need more than the 24 hours retention, in which case it’s cheaper than New Relic:

    Longview: 1-3 servers for $20/mo
    New relic: 1 server for $50/mp ($25/mo with annual commitment)
    2 servers? $100/50. 3 servers? $150/75.

    To be fair to New Relic, they do have special pricing to SMBs, and will contact you when you sign-up. Still, as Caker said, this is a v1.0 for Longview, and as we know, all 1.0 products can only improve. 🙂

    As a new-relic and server density customer, I find the Longview offering very competitive and something that I will be investing in.

  20. Author Photo

    It would be nice if we could see disk space as a percentage of available capacity on the dashboard screen.

  21. Author Photo

    http://www.bijk.com – $11mth for 1 server, including 15 SMS notifications and 12mths retention. You’ll have to do better longview.

  22. Author Photo

    24 hours would be the sweet spot here.

  23. Author Photo

    Linode, thank you for new feature, but I would agree with others, who say that 30 min is useless.
    I have just 1 linode for now + backup plan and I think it’s too much for me for Longview Pro.

    Btw, talking about munin and Relic, do you plan to have metrics for nginx/apache/mysql/php?

    Thnx.

  24. Author Photo

    Just wanted to add that LongView now offers 12 hours of data for the free plan.

    I was JUST ABOUT to skip installing it after reading all the complaints about how 30 minutes is useless – you guys should update this post!

    I have followed steps for installation of longview
    but when i paste “curl -s https://lv.linode.com/Xnt2 | sudo bash” (changed) it giving me error like
    -bash: curl: command not found
    sudo: unable to resolve host .
    Please tell me the solution.

    Note I have replaced the key from my Linode in above command

  26. Author Photo

    You’ll need to install curl to fix that issue, and correctly set your hostname to fix the second. Details on setting your hostname can be found here:

    Someone mentioned this above.
    It would be nice if we could see disk space as a percentage of available capacity on the dashboard screen.
    I agree – would be great. Our linodes have had full disks on a number of occasions.
