Keeping your company’s business-critical Linux systems humming along smoothly is challenging. By the time performance bottlenecks and tuning opportunities present themselves it’s too late – your users are already affected by your slow or unresponsive website or application. This infuriates your users and costs you money.
Your Linux systems generate data — data that can be extremely valuable to your sysadmin duties. Data that can help eliminate those bottlenecks and avoid downtime. Data that can help you make decisions about load distribution to ensure systems run more efficiently. Data that helps you be better prepared for unexpected spikes in traffic, and helps you make more informed decisions concerning the future, using data from the past. We set out to build an analytics tool to solve this problem. The result: Longview.
Longview is a new statistics collection and graphing service. It logs all of your system-level metrics and displays them in eye-catching zoomable graphs. Longview makes it easy to gain instant insight into the resource use of your servers and to spot trends in things like CPU, memory, network, and processes.
You can get a bird’s-eye view of your entire fleet, or focus in on one particular server to display detailed information about running processes, listening services, active connections, and available updates. It lets you monitor disk I/O and network traffic and a whole lot more. And, it all looks absolutely amazing!
The Longview agent is open-source and can be installed on any supported Linux system – it does not need to be a Linode. Supported distributions are: Debian, Ubuntu, CentOS, and Fedora. There is also a tarball distribution of client for the cool kids.
Automatic installation is easy – just log into the Linode Manager, click the Longview tab, click “Add Client” and then copy/paste the one-line installation command into any supported Linux system. Within moments your graphs will start populating. The longview-agent uses your system’s package management tools, so updating and/or removing it later is easy.
