How do I manage discovery settings?

Follow

Once the Auvik collector is successfully installed on a network, it automatically scans its local subnet to find more networks and devices. By adjusting the discovery settings, you can control how frequently the scan is completed, specific OIDs that should be monitored, and which services should be used to access data.

Changing the discovery settings from your MSP dashboard applies the settings to all your clients. To change a setting for a specific client, you must change the setting from that client’s dashboard. Note: Settings changed from the client’s dashboard are not overwritten by any settings changed from your MSP dashboard.

Setting descriptions

Setting

Description

Subnet scanning frequency

In seconds, how often you want Auvik to scan a subnet. 

The recommended value is 30 seconds or higher. 

To stop scanning, you must mark the subnet as Don’t Scan. When you stop a network from being scanned, any devices already discovered continue to be monitored, but no new devices will be discovered.

Subnet per period

How many subnets should be scanned in a five-minute period.

Used to limit the number of subnets scanned to avoid overwhelming a large network with scanning traffic.

Device deletion threshold

How many days an identified device needs to be offline before it’s deleted from inventory. 

A device is considered identified if it’s been successfully logged through one of Auvik’s discovery protocols (such as SNMP or WMI), and we’re receiving updated details to classify the device.

Once the deletion threshold has been reached, the identified offline device is removed from inventory, including all device history.

Unidentified device deletion threshold

How many days an unidentified device needs to be offline before it’s deleted from inventory. 

A device is considered unidentified if SNMP isn’t successful or isn’t available. Unidentified devices appears as generic devices.

Once the deletion threshold has been reached, the unidentified device is removed from inventory, including all device history.

We’re continually adding new data to Auvik so that unidentified devices show up less and less. To request we add information for a device Auvik can’t currently identify, contact support@auvik.com with the device OID.

Configuration backup period

In minutes, how often you want a device to be polled for configuration changes. 

This setting doesn’t change how often Auvik initiates a login to the device.

If you don’t want Auvik to back up configurations, change the time interval for backups to 0 days. The no-backup setting applies globally to all devices—it can’t be changed for a specific device. 

HealthCheck ICMP ping timeout.

How many seconds before ICMP pings should time-out.

Stacking feature

Select whether to enable or disable the identification of stackable switches. Enabled by default.

We don't recommend disabling stacking as your visibility into switch stacks will then be limited. If you do disable it, Auvik removes all previously identified member associations. You can always re-enable stacking later. 

CLI session feature

Select on-demand or persistent CLI sessions to devices.

On-demand is the default. 

On-demand: Auvik will SSH or Telnet into a device when we need to run commands. We then close off the session. Use this in cases where the account Auvik is using may be locked while in use.

Persistent: Auvik keeps the SSH or Telnet session open indefinitely (until it times out or the device kills it) and continues to run commands on the intervals we need to. Use this when there’s a limit to the number of logins 

that can occur on a device.

Intelligent platform management interfaces as independent devices

Select whether to enable or disable IPMI devices, such as iDRAC or iLO, from showing as independent devices. Enabled by default.

If enabled, an IPMI device shows as a separate device on the map. If disabled, an IPMI device doesn’t show on the map as a device because it’s included as an IP address for the parent device.

Serial number source for WMI

Select whether to pull the serial number for Windows Server or workstations with the OS or BIOS. OS is the default.

Be aware! Switching the serial number source can affect your Autotask or ConnectWise Manage integration.

If you’re using serial numbers as device identifiers and Auvik has already synced configurations against the OS serial number, the next sync could result in duplicate configurations being created because the serial numbers will no longer match.

If you're not using serial numbers as device identifiers, and are syncing the serial number field, it will be updated on the next sync. On the off chance that serial numbers are the same across multiple devices, those devices may be merged into a single configuration during an inventory sync.

Topology discovery

(Coming soon) 

Select the algorithm (1st gen or 2nd gen) you’d like to use to draw your network maps. After saving the changes, it may take a few minutes for your maps to be redrawn.
