See which servers are running hot

The Capacity & growth report shows CPU, memory and disk for every server over a month you choose — and which disks are filling up.

See at a glance which servers are stretched on CPU, memory or disk, and which disks are about to run out of space — built for anyone deciding what needs resizing.

Overview

  • Shows CPU, memory and disk for every server in your fleet over a month you choose, side by side.
  • Highlights disks that are steadily filling up, with a rough time-to-full estimate.
  • Unlike a single server's own page, this report covers your whole fleet at once, which is what you want when comparing servers and deciding what to resize.

Read a row

  1. Look at the peak figure for the month — this is the highest the server hit.
  2. Check the average underneath it — this is the typical level.
  3. Glance at the small line next to the numbers to see the shape of the month at a glance.
  4. Watch for colour: numbers turn amber above 75% and red above 90%.

NotePeak and average together tell you something neither does alone. A server sitting at a steady 60% and a server with one bad afternoon can show the same average, but only the peak reveals the spike.

Understand "12 of 31 days"

  1. Check the days-measured note on each row before comparing servers against each other.
  2. If a server shows a low count out of the month's total, treat it as a partial reading rather than a full picture — it may have been added part-way through the month.
  3. If a row shows "No readings", read that as no data received, not as zero usage.

Check disk forecasts

  1. Look for a note like "full in ~9d" next to a disk that's on a steady filling trend.
  2. Remember this forecast is based on the last week of readings, so it only appears for a period that includes today.
  3. Don't expect a forecast on every disk — one-off dumps or caches that fill and empty aren't on a steady trend, so no forecast is shown for them.

TipIf a disk you'd expect to see a forecast for doesn't have one, it likely means its usage pattern isn't steady enough to project safely — that's by design, not a bug.

Export the report

  1. Select Export CSV to download the month exactly as shown, including the days-measured columns so the figures can be checked later.
  2. Know that every export is recorded in your Audit Log for accountability.
