Why six are running, and what two would save.
#cloud-costprivate channel3 tool calls
Six identical instances, a question about why, and what two would save. It reads the instance group, a day of CPU per machine, and puts the saving beside the recommendation — a decision it hands to a person with the table already made.

Six identical webhook-handler VMs in a managed instance group, and six is the group’s configured target size — so all six are always up. About $70 a month together.
- Average CPU over 24 hours: 1.5–2.5% per instance, with brief spikes to ~100% on two of them
- At two instances: roughly $46 a month saved, with headroom for the spikes
They are real VMs, but they live in the staging project — the list you are looking at is testing’s. Console path below.

How the turn went
What they are, whether six is right, and where they live.
- 01
What are these
The instance group’s own metadata answers it: a managed group with a target size, which is why six are always running.
- 02
Whether six is right
A day of CPU per instance from Monitoring, into the sandbox for averages and peaks. The recommendation carries the numbers it rests on.
- 03
Where they are
“I don’t see these in the VM list” was answered by re-querying and naming the project — and giving the console path to find them.
What it needs
The setup, in the console.
What it will not do
Enforced outside the model.
Resizing the group is a write the presets cannot make. It recommends; it does not act.
It answers from the metrics it can read, and says which project they came from.
