Linode Longview

企業のビジネスクリティカルな Linux システムを円滑に維持することは困難です。パフォーマンスのボトルネックやチューニングの必要性が明らかになる頃には、ユーザーは既に低速または応答しない Web サイトやアプリケーションの影響を受けています。これはあなたのユーザーを怒らせ、あなたにはコストがかかります。

Linux システムは、システム管理者の職務にとって非常に価値のあるデータを生成します。それはボトルネックを解消し、ダウンタイムを回避するのに役立つデータです。負荷分散に関する意思決定に役立つデータです。トラフィックの予期しない急増に対する準備を改善し、過去のデータを使用して将来に関するより多くの情報に基づいた意思決定を行うのに役立つデータです。 我々はこれらの問題を解決するための分析ツールの構築に取り組みました。その結果が、Longviewです。

Longview の概要

Longview1Longview は、新しい統計収集およびグラフ化サービスです。すべてのシステム レベルのメトリックをログに記録し、目を引くズーム可能なグラフに表示します。Longviewを使用すると、サーバーのリソース使用率を即座に把握し、CPU、メモリ、ネットワーク、プロセスなどの傾向を簡単に把握できます。

フリート全体の鳥瞰図を取得したり、特定のサーバーに焦点を当てて、実行中のプロセス、リスニング サービス、アクティブな接続、および利用可能な更新に関する詳細情報を表示したりできます。これにより、ディスク I/O とネットワーク トラフィックを監視できます。何より素晴らしく見えるのです!

インストール

Longviewエージェントはオープンソースであり、サポートされている任意のLinuxシステムにインストールできます。 - Linode である必要はありません。サポートされているディストリビューションは、Debian、Ubuntu、CentOS、および Fedora です。クールな奴らのためのクライアントの tarball ディストリビューションもあります。

自動インストールは簡単です - Linode マネージャにログインするだけで、[ Longview ]タブをクリックし、[クライアントの追加]をクリックして、サポートされている任意のLinuxシステムに1行のインストールコマンドをコピーして貼り付けます。瞬時にグラフが設定され始めます。longview-agent はシステムのパッケージ管理ツールを使用するため、後で更新や削除を行うのは簡単です。

費用はいくらですか?

基本版Longviewは完全無料で、5分間のデータ解決と30分のデータ保存が含れます。

アカウントをLongview Proにアップグレードすると、毎分の解像度と無制限のデータ保持が可能になり、次のパックで利用できます。

  • 最大 3 台のサーバー: $20/月
  • 最大 10 台のサーバー: $40/月
  • 最大 40 台のサーバー: $100/月
  • 最大 100 台のサーバー: $200/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.
