When you've graduated from free tools, try Scout.
Free monitoring tools get you off the ground. Scout is a tool for the next step.
Over half of Nagios, New Relic, and Zabbix users that deploy Scout become paying customers.
Scout collects key performance metrics automatically: CPU, Memory, Disk, Network, and process data are gathered from every server. Go from zero to 100% visibility in minutes.
Scout's plugin-based architecture makes it infinitely flexible. Our 80+ plugins monitor the staples like PostgreSQL, Nginx, and Redis and you can easily extend with your own. Best of all, most plugins can be configured with just a button click (or two).
Just install our agent and you've got monitoring. You'll be up and running quickly with our simple bash installer, Chef, Ansible, or Puppet instructions. You can even tweak how Scout monitors your different server roles without a complicated config syntax.
Your key performance metrics have never looked better.
Let's build a dashboard in under 60 seconds.
Your charts stay updated as your servers come and go. Filter by environment, server role, or server name (of course, we support regexes and wildcards).
Just click the icon to switch to realtime mode, updating your charts with fresh data every second.
Build your dashboards exactly how you need them.
Easily provide access to dashboards to those outside your regular dev team.
Have dozens of servers? Scout handles displaying metrics across many servers on a chart with ease.
View 30 days of high-resolution, one-minute updates and a year of daily summaries.
Going beyond simple threshold alerts, Scout also watches for significant trends in your data. For example, did the amount of free disk space go down dramatically in the last hour? Did the number of slow DB queries increase significantly relative to last week?
From the basics (email and SMS) to the more advanced (webhooks, Pagerduty, Hipchat, etc), it's easy to integrate Scout's notifications into your team's workflow.
Scout's Notification Groups make it easy to use different notification channels for different alert priorities (for example, use SMS for urgent notifications and email for warning notifications).
Leading companies depend on Scout.
Over the last 24 hours, we've processed 1,000,000,000 metrics, sent 10,0000 alerts, and rendered 100000 dashboards for 10,000+ happy developers.
“Scout's flexible alerting, intuitive charts and dashboards, and first-class support brought a grateful end to our previous monitoring jumble of Nagios-Cacti-Zabbix.” Didip Kerabat, DevOps at Kongregate
Added Memcached to your app servers? It's one-click and zero deploys to start monitoring it. In most cases there's no reason to SSH onto your servers to monitor.
From Apache to Zookeeper, we likely have you covered. All plugins in our directory are open-source, and many were created by members of our active community.
If you need custom monitoring functionality, it's easy to write a new plugin. Plugins are small Ruby programs that run each time the agent runs. Scout plugins tend to be very small and easy to work with.
Need to change an alerting threshold across your database servers? One click. Adding a plugin to your application servers? One click.
Scout’s roles-based approach keeps monitoring in-sync across your evolving server footprint.
Just install Scout’s lightweight agent - there’s no separate monitoring server to manage. Scout automatically monitors new servers when they come online.
Using configuration management tools? We've got you covered with a Chef recipe and a Puppet module.
Scout's roles-based approach makes monitoring forty servers as easy as monitoring four. Instead of updating monitoring settings on individual servers, just update the role settings. Everything stays in sync.
