FINOPS · AUTOSTOPPING
Stop paying for servers nobody is using.
AutoStopping watches the compute you choose and stops it when CPU and network have both been quiet for your idle window. Start it again with one action, and see the savings it made.
The usual way
Staging runs all night, and all weekend.

How it works
Choose, watch, stop
Choose resources and an idle window
Pick a cloud account, the resources this rule covers and an idle threshold in minutes.

Example data.
Watch CPU and network
A resource is idle only while both signals stay below their thresholds. Rules are checked every 5 minutes.
✓ CPU 1.2%
below 2%
✓ Network 18 KB/s
below 50 KB/s
Example data.
Stop, then start with one action
The rule stops chosen resources after the idle window. Use Start on the rule when you need them again.
active → cooling → stopped
Power state: stopped · read live from AWS
Start with one action on the rule.
Example data.
Idle detection
Idle means really idle
Move the CPU and network readings. Both must stay below their thresholds for the idle window before a stop. When network cannot be read, the CPU threshold is stricter.
When network cannot be read, CPU must be below 1%.
Example data.
Supported compute
Only the compute you choose
A rule names one cloud account, the resources it covers and an idle threshold in minutes. Only resources you put in a rule are ever stopped.
Example data.
Rule detail
Every stop on record
Each rule shows Idle time, Compute, Savings and Last activity. Its detail drawer shows cumulative savings, spend versus savings for the last seven days and state changes. Savings use the latest cost report; when cost is unknown, they stay at 0.

On the Pro plan
Stop the waste you can see coming
Put a quiet idle window around the compute you choose, then see when it stopped and what it saved.
Questions
Frequently asked questions
AWS EC2 instances and Auto Scaling groups, Azure virtual machines, and DigitalOcean Droplets. Azure virtual machines are deallocated when stopped; DigitalOcean Droplets are powered off. Only resources you put in a rule are ever stopped.
