Linux Events

Logon Tracker also collects SSH events on Linux machines. The “LT Assigned Status” column reflects the status that Logon Tracker assigns to each event. These statuses are relevant to the module configuration (see Configuring Logon Tracker Agent Policy) and the UI search functionality (see Search Controls).

Note

For this release the Logon Tracker module collects only SSH related events.

Backfilled Event Timestamps

Depending on the configuration, Linux event timestamps may not include the year. To deduce the correct year for backfilled events, the last modified timestamp is used as a starting point. This is a best effort to determine the correct year for the events and may not be accurate in all cases.
