Read a server’s graphs and activity

The Stats tab draws how hard a server works over time. Use it to see whether a server is too small, too big, or busy at a certain hour. The data comes in 5-minute steps and is kept for 30 days.

Open the graphs

1. Open the server’s page, then the Stats tab.
2. Pick a time range: 1h, 6h, 24h, 7d or 30d, or Custom for your own dates. The default is the last 24 hours.

The graphs

• CPU Usage shows the share of the server’s vCPUs in use, in percent, from 0 to 100. Under about 70% most of the time is healthy. A server near 100% for long stretches needs more vCPUs. See Resize or reinstall a server.
• Memory Usage shows Memory Used against the server’s memory, shown as a line marked Allocated. Memory close to the allocated amount for a long time means the server needs more. Some servers don’t share this, and you see This Server Does Not Report Memory Usage.
• Disk Usage shows Read and Write. Switch between IOPS (operations per second) and Throughput (bytes per second).
• Network Usage shows Received and Sent for one interface. Choose the interface in Select Interface. Switch between Traffic (bytes per second) and Packets (packets per second).

Blank stretches are times the server was stopped. Counters Restarted marks a point where the server restarted its counters, for example after a reboot.

Change the view

• Statistic switches between Average and Peak. Peak shows the highest value in each step and needs 7 days or longer.
• Previous Period draws the period before as a second line, to compare.
• Drag across any chart to zoom. Reset Zoom goes back. Earlier and Later move the window.
• View as Table shows the numbers in a table.

Hover over a chart to read the values at one moment on every chart at once.

If something goes wrong

• That selection is too short to show. Drag across a wider stretch.
• The previous period is older than the 30 days the platform keeps.
• If the graphs are empty, the server may have been stopped in that period.

Review the server’s activity

The Activity tab is the history of one server. Every power action, resize, volume change, firewall change, backup and reinstall is listed, newest first. Use it to find out what changed and when.

Read the activity

1. Open the server’s page, then the Activity tab.
2. Each row shows Date, Action, Who, Status, Duration and Details.

• Action names what happened, for example Server Rebooted, Volume Attached or Firewall Rule Added. Backup actions read Backup Created, Backup Renamed, Backup Restored to a New Volume or Backup Deleted.
• Who is the person who started it. Stack Harbor means the platform or our team did it, for example Platform Maintenance or an Automatic Backup.
• Status says whether it worked.
• Details adds the size, volume, network, address, group, backup or snapshot it touched.

No activity recorded yet. means nothing has happened on the server yet.

A very old server can show This server has a long history: its oldest platform actions may not be listed.
