Devices

Edit online

The Devices (Device Manager) page in Data Insight is the eventual successor to the Device Manager in SevOne NMS. At present, it enables you to quickly filter, search, sort, and export the inventory of devices SevOne monitors. It also allows quick access to related reports via Global Report Linking.

To access the page, click Devices in the left navigation bar.

Filter

Edit online

The left panel is to add/apply the Filter. Enter the fields in the panel to apply the filter(s) on.

  1. Click the Datasource drop-down and select the SevOne NMS cluster or appliance. This is a required field.
    Note: If you are unable to connect to a datasource from the list available, you will get an error indicating that your SevOne Data Insight is unable to communicate to the selected NMS datasource.
  2. Click the Peers drop-down and select one or more peers from the drop-down. For example, select qa-b9b95.

    Example

    Important: Since 1 peer is added in field Peers, you will see Filter Count as the filter count in the upper-right corner. This means that there are 2 pieces of the information, staging-soa and staging-soa1, that the filter will be applied on.

    Device Filter

    To delete the filter(s) added, you can either:

    1. click on the peer selected, qa-b9b95. If you click Delete icon next to qa-b9b95, it will delete the peer and the filter count in upper-right corner will go away as there are no peers set in field Peers.
    2. click Delete icon to delete on Peers field to clear all peers added as a filter.
    3. click Delete icon next to Filter Count to delete all filters.
  3. Click the Device Groups drop-down and select one or more devices from the list.
  4. Click the Alerts drop-down and select one or more alert severity level (Emergency, Alert, Critical, Error, Warning, Notice, Info, Debug). For example, select Emergency, Alert, and Warning.
    Important: Since 3 alert severity levels (Emergency, Alert, and Warning) are added in field Alerts, you will see Filter Count in the upper-right corner. i.e.,
    • 1 filter added in field Peers
    • 3 filters added in field Alerts

    which results in 4 pieces of information that the filter will be applied on.

    Device Filter

    To delete the filter(s) added, you can either click Delete icon to delete one filter at a time on the field or click Delete icon to delete all filters on the field. Or, you can click Delete icon next to Filter Count to delete all filters.

  5. In the Discovery Status drop-down, select one or more discovery status. For example, New, Queued, Working, Finished, Deleting, and None.
  6. Under Technology, click Show more to view the entire list of available plugin technologies. For example, SNMP, AWS, AZURE, BULKDATA, COC, etc. Each plugin has 3 columns.
    1. Working - select the check box to filter the list of devices and display the devices where the plugin is successfully collecting the metrics.
    2. Not Working - select the check box to filter the list of devices and display the devices where the plugin is not collecting the metrics.
    3. Disabled - select the check box to filter the list of devices and display the devices where the plugin is disabled.

Based on the filter(s) selected in the examples above, the top-right and bottom-right panels reflect the results i.e., Filter Count filters have been applied.

In the top-right panel, you will see the number of devices and its respective device alerts, after the filter was applied.
