Manter os sistemas Linux críticos para os negócios da sua empresa funcionando suavemente é um desafio. Quando os gargalos de desempenho e as oportunidades de ajuste se apresentam é tarde demais - seus usuários já estão sendo afetados por seu site ou aplicativo lento ou sem resposta. Isto enfurece os seus utilizadores e custa dinheiro.
Os seus sistemas Linux geram dados - dados que podem ser extremamente valiosos para as suas tarefas de administrador de sistemas. Dados que podem ajudar a eliminar esses erros e evitar tempos de inatividade. Dados que podem ajudar a tomar decisões sobre a distribuição de carga para garantir que os sistemas funcionem de forma mais eficiente. Dados que o ajudam a melhorar e preparar para picos inesperados no tráfego e o ajudam a tomar decisões mais informadas sobre o futuro, usando dados do passado. Nós nos propusemos a construir uma ferramenta analítica para resolver este problema. O resultado: Longview.
Apresentação de Longview
Longview é um novo serviço de recolha de estatísticas e de gráficos. Ele registra todas as métricas do seu sistema e as exibe em gráficos atraentes com zoom. Longview torna fácil obter uma visão instantânea do uso dos recursos dos seus servidores e detectar tendências em coisas como CPU, memória, rede e processos.
Você pode obter uma visão aérea de toda a sua frota, ou concentrar em um servidor específico para exibir informações detalhadas sobre processos em execução, serviços de escuta, conexões ativas e atualizações disponíveis. Permite monitorar a E/S do disco e o tráfego de rede e muito mais. E, tudo parece absolutamente incrível!
Instalação
O agente Longview é open-source e pode ser instalado em qualquer sistema Linux suportado - não precisa ser um Linode. As distribuições suportadas são: Debian, Ubuntu, CentOS, e Fedora. Há também uma distribuição de tarball de cliente para as crianças legais.
A instalação automática é fácil - basta entrar no Linode Manager, clicar na guia Longview, clicar em "Add Client" e depois copiar/colar o comando de instalação de uma linha em qualquer sistema Linux suportado. Dentro de momentos os seus gráficos começarão a povoar. O agente longview utiliza as ferramentas de gerenciamento de pacotes do seu sistema, por isso é fácil atualizar e/ou remover mais tarde.
Quanto custa?
O Longview básico é completamente GRATUITO e inclui 5 minutos de resolução de dados e 30 minutos de retenção de dados.
Atualizar a sua conta para o Longview Pro permite uma resolução a cada minuto e uma retenção de dados ilimitada, e está disponível em pacotes de:
- Até 3 servidores: $20/mês
- Até 10 servidores: $40/mês
- Até 40 servidores: $100/mês
- Até 100 servidores: $200/mês

Since this works on non-linode systems, does that mean I can install this on my Raspberry Pi at home?
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.
How does this affect Longview Pro beta users?
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?
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.
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.
I have one linode instance,the free version is enough for me.
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.
Any chance for some docs on how the agent interacts with the dashboard, and what exactly thr dashboard does with this data?
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.
It would be nice if we could see disk space as a percentage of available capacity on the dashboard screen.
http://www.bijk.com – $11mth for 1 server, including 15 SMS notifications and 12mths retention. You’ll have to do better longview.
24 hours would be the sweet spot here.
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.
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
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:
https://www.linode.com/docs/guides/getting-started/#sph_setting-the-hostname
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.
