Polling Settings
The Polling Settings view establishes how often statistics are polled, and how long the data are maintained in the SolarWinds Platform database.
Changes to database maintenance and retention settings do not take effect until the SolarWinds Network Performance Monitor service is restarted.
Polling Intervals
Configure how frequently the polling engine requests information from devices.
-
Configure polling intervals (devices currently monitored and added in the future)
Use these steps to change polling settings for both currently monitored devices and for devices you will add for monitoring in the future.
- Go to Polling Settings and edit the polling intervals.
- Decide what to do about custom settings for individual entities you might already have:
- To keep customized values, make sure the Lock custom values box is selected.
- To overwrite any customizations you might have for individual entities, clear the Lock Custom Values box.
- Click Reapply. This sets the new value for currently monitored devices.
- Click Submit. This sets the new value for devices you might add for monitoring in the future.
When you return to Polling Settings, you will see that the value you changed is saved. The changed setting will be used for both devices monitored at the moment and for all devices that you add for monitoring from now on.
-
Change Polling Intervals only for devices you might add in the future
- Go to Polling Settings and edit the polling intervals.
- Decide what to do about custom settings for individual entities you might already have:
- To keep customized values, make sure the Lock Custom Settings box is selected.
- To overwrite any customizations you might have for individual entities, clear the Lock Custom Settings box.
- Click Submit. This sets the current value for devices you might add for monitoring in the future.
When you return to Polling Settings, you will see that the value you changed is saved. The changed setting will be used for all devices that you add for monitoring from now on. This change does not affect devices you are already monitoring at the moment.
-
Change polling intervals for already monitored devices
- Go to Polling Settings and edit the polling intervals.
- Decide what to do about custom settings for individual entities you might already have:
- To keep customized values, make sure the Lock box is selected.
- To remove any customizations you might have for individual entities, clear the Lock box.
- Click Reapply. This sets the current value for currently monitored devices.
- Leave the Polling Settings page without submitting your changes.
The change is applied on all devices you are currently monitoring in the database. When you return to the Polling Settings page, you don't see any changes. The setting you changed has the original value. Devices that you add for monitoring from now on are not affected by the change, they will use the setting currently specified on the Polling Settings page.
Available options
Setting | Default value | Description |
---|---|---|
Default Node Poll Interval | 120 seconds | The interval for polling the status and response time of monitored devices. |
Default Interface Poll Interval | 120 seconds | The interval for polling the status of monitored interfaces. |

Default Rediscovery Interval | 30 minutes | The interval for polling the entire network to detect any re-indexed interfaces. Monitored network devices are also checked for IOS upgrades or EnergyWise support. Rediscovery scans your network for changes to your monitored nodes. If you want to discover changes to your environment, schedule a network discovery to occur on a periodic basis and check the scheduled discovery results. The minimum rediscovery interval is five minutes (in earlier versions, the interval was one minute). You cannot submit polling interval settings if the default rediscovery interval is not set to at least five minutes. |
Default Asset Inventory Poll Interval | 1 day | The interval for checking asset inventory. Relevant for SAM and SCM. |
Lock Custom Values | Selected | Select this option to keep any customized status polling interval settings. |
Re-Apply Polling Intervals | Button enabled | Click Re-Apply Polling Intervals to apply the settings specified in this section to all objects in the database. Click Submit at the bottom of the page to use the current settings for new objects. If you leave the page without submitting the changes, your settings will be applied to objects in the database, but will not be saved as default. For objects added to the database in the future, the default settings will be used. Not submitting the changes can result in different settings for objects that are already in the database, and different settings for newly added objects. |
Polling Statistics Intervals
Configure the intervals on which Orion completes SNMP statistics polls.
-
Configure polling statistics intervals (devices currently monitored and added in the future)
Use these steps to change polling settings for both currently monitored devices and for devices you will add for monitoring in the future.

Click to immediately apply the settings specified in this section on all objects in the database. Make sure you click Submit if you want to use the current settings for new objects.
If you leave the page without submitting the changes, your settings will only be applied on objects in the database, but will not be saved. For objects added to the database in the future, the saved settings will be used. Not submitting the changes might thus result in different settings for objects that are already in the database and different settings for newly added objects.
Database Settings
Configure the time of day when the database maintenance runs, and how long data are retained in the SolarWinds Platform database.
For details about retention settings for monitored cloud accounts, see Edit retention settings for cloud-related statistics.
Shortening retention periods can improve your database performance. However, if you increase retention periods, it can cause excessive overhead on your SQL server and introduce issues such as:
- Increased I/O
- Increased table sizes
- Database maintenance issues where nightly maintenance fails to complete or runs indefinitely
- Web performance issues
- Chart loading issues
Consider your SQL environment resources, such as disk space and hardware configuration before you change the retention periods. See this SolarWinds support article for database best practices.
It can take more than 10 minutes to propagate some changes to SolarWinds Platform database settings.
