History

Activity lists saved sessions. Switch to Changes for what monitoring rules found, newest first. The badge counts changes you have not acknowledged.

Settings › History sets how many sessions are kept and for how long. The choices are 100, 250, 500 or 1000 sessions, and 30, 90, 180, 365 or 730 days. A new install starts from 500 sessions and 180 days unless you change it.

Favourites and imported sessions are not removed by those limits.

  1. Open a session to read it or repeat it with the same setup.
  2. Pull to refresh reads saved results again. It does not start a measurement.

What the result means

A check with no answer is stored as no answer, never as 0 ms. A scan that stopped early stays marked as partial.

Illustrative example. Not a map of a physical network and not a live capture.

Comparison

Choose Compare two sessions and two port scans or discoveries of the same target, then Show differences.

The baseline is first. Address, name, type, open ports and services line up in the same rows.

A plus is new, a minus is no longer seen, a pencil is changed. A field that was not measured says so. It is not shown as removed.

If device history is not available yet, devices are matched by address only.

What the result means

When identity evidence ties the two rows together, the device stays the same device after an address change. The address change is a change of address, not a new device and not proof that the old address is offline.

Charts and export

Dashboard charts of a profile show devices that responded per saved scan of the same range. Striped bars are scans that stopped early. Missing scheduled scans are dashed, not zero, and only where a rule schedule expected a scan.

The latency chart uses real checks, including saved Ping runs to that address. Checks without an answer break the line. They are not 0 ms.

Every chart has Show as table.

  1. Export JSON for exact values, CSV for a spreadsheet (formula-like cells are escaped), or PDF for a readable report.
  2. An export contains addresses, names, open ports and raw outcomes of that session. It does not contain SNMP credentials.

What the result means

Share an export only with people who should see that network.

Deletion

  1. Lower the session count or the number of days in Settings › History and confirm. Favourites stay.
  2. Delete a network profile separately. That removes the profile, its rules, baseline and changes. Sessions remain in Activity.
