Data resolution and retention

Event data resolution

To allow for more efficient troubleshooting, metrics in operational data are available with high resolution, either 5-minute or 15-minute, and low resolution, 1-day.

The VDI Experience license allows extra fine data resolution of VDI metrics at 30-second intervals. See the Retrieving high-resolution data for Desktop Virtualization documentation for details.

To access high-resolution data, you must use a timeframe expressed in minutes or hours in the during past clause.

devices during past 24h
| include session.events during past 24h 
| compute total_user_interaction = user_interaction_time.sum() 
| where total_user_interaction > 8h
| list device.name, total_user_interaction 

To access data in low-resolution, you must use a timeframe expressed in days in the during past clause.

devices during past 30d
| include session.events during past 30d 
| compute total_user_interaction = user_interaction_time.sum() 
| where total_user_interaction > 10d
| list device.name, total_user_interaction 

Contrary to metrics in operational data, trend data metrics are available only with low resolution, either 1-day or 7-days.

Retention per data category

Data retention refers to the period of time for which the specific set of data is stored and accessible through dashboards and investigations. The following table summarizes the general rules of retention per data category. The retention periods represent the default platform settings. You can customize them on the Data management page.

Data category	Data subcategory	Retention	Example
Object	Inventory objects	30 days from the time of the object’s last activity	devices mobile_devices users binaries packages
Object	Configuration objects	Indefinite, until deleted by a Nexthink account	campaigns remote_actions workflows monitors
Events	Operational data	30 days from the time of the event ℹ️ Exceptions: execution.events, connection.events, connection.tcp_events and connection.udp_events at high resolution are retained for 14 days. Additionally, you can only access a maximum of 8-days data in a single query. 30-second high-resolution data for VDI is only retained for the past 48 hours.	execution.events execution.crashes device_performance.events device_performance.mobile_events remote_action.executions workflow.executions web.events
Events	Trend data	Ranging from 90 days to 13 months, depending on the use case Software metering: 90 days Web applications trends: 90 days Remote action execution summaries: 13 months Workflow execution summaries: 13 months Custom trends: 13 months DEX trends : 13 months ℹ️ Exception: Campaigns data (campaign.*) is stored indefinitely.	custom_trend.* software_metering.events remote_action.executions_summary workflow.executions_summary ℹ️ Web applications and DEX trends are not available in NQL, they are only available in the related module dashboards.
Events	Audit logs	180 days from the time of the event	platform.audit_logs
Events	Execution logs	30 days from the time of the event	platform.custom_trends_logs platform.data_export_logs

The last_seen field in the NQL does not account for all the device connections to the Nexthink instance (such as TCP handshakes or remote actions), so it is not a reliable indicator of device retention period. Refer to NQL data model and Monitoring device last activity for more information.

Data availability in modules

Product modules allow you to access the object and event data described above. The available data value indicates how far back in the past you can retrieve the data for a given module.

Module	Available data
Amplify - usage data	90 days
Digital Experience	395 days
Alerts overview	30 days
Diagnostic view	14 days
Device View	30 days*
Applications - web applications	30 days - operational data 90 days - trend data
Applications - desktop applications	14 days
Live Dashboards	30 days - operational data 395 days - trend data
Remote Actions	30 days - operational data 395 days - trend data
Campaigns	10 years
Software Metering	90 days
Workflows	30 days
Desktop Virtualization	2 days - 30-second data resolution 30 days - 5-minute data resolution

* The number of hours displayed on the page depends on your screen resolution.

All time-related data displayed in the Nexthink web interface is converted to the user's time zone.
