Ruby, Elixir, Node.js & Python Host Monitoring
Get a 360° view of your host metrics.
Software can only run with hardware, whether it’s shared or completely self-managed. Our hardware monitoring keeps an eye on all the metrics for all your servers.

All Host Metrics in one place
Get real-time and historical data for CPU, memory, disk, network usage, and more. All from one simple overview.
Spot performance issues fast
Visualize key metrics to quickly identify underperforming hosts, outliers, and performance issues.
Target the root of a problem
Easily identify whether hardware or code is causing issues. View detailed host metrics on all error and performance incidents.
All Host Metrics
One complete picture of your hardware.
AppSignal provides you with metrics for all your hosts. Stop using separate and complicated host monitoring tools. Simply run AppSignal and get host data alongside your errors and performance insights. In real-time, but also for two days or two years ago.
CPU usage
Get information about CPU usage, now or in the past.
Disk I/O
Check disk performance at any given moment.
Disk usage
Are your disks half full or half empty? Find out easily.
Load average
Use load average insights to know if you need to scale up.
Memory usage
How is your memory holding up? See how much is being used.
Network usage
Need a bigger pipe? Keep track of data sent and received.
Drill down
Inspect and compare hosts.
Get a quick overview of your hosts with the most important metrics. Drill down into a specific app, or compare multiple hosts to find which host is not behaving as it should.

Visualise
CPU, disk, network, memory.
Compare all host metrics you can think of. The graphs make it easy to spot outliers and identify under-performing hardware.

Host metric context
Check host metrics for troublesome requests.
Sometimes issues are caused by your hosts running amok. That’s why we keep track of host metrics for each error sample. Discover when to optimize your infrastructure before blaming lines of code.

Make your next crash make sense.
