There are multiple reasons why a session may not be reporting any log on duration data. The most common reasons are the following:
- If any stage or duration took less than .001ms, the measurement does not register a valid value.
- If a substage is not configured as part of log on duration then it will not be displayed.
- Reconnected sessions will not show all stages (because not all stages occur during a reconnect).
