User Guide: Vista Manager AWC Plug-in version 3.16.0

# Vista Appliance Storage

AWC plug-in can use AT-VST-APL, which is on the same subnet as Vista Manager EX, as extended storage for AWC plug-ins. This feature is called Vista Appliance Storage (VAS) and can record the management status of the APs and the status of the associated wireless clients.
This screen allows you to detect and configure AT-VST-APL that can be configured as a VAS, observe the status of the VAS, and export and import the historical data recorded in the VAS.
The AT-VST-APL, which can be configured as a VAS, requires the AWC-VAS application to be running.
The AWC-VAS application is installed on the AT-VST-APL management screen.

> Note

> > When using the AWC-VAS application, AT-VST-APL must be configured for VAS only. Applications other than AWC-VAS cannot be used.

> Note

> > Set a static IP address for the AWC-VAS application container. If you set up a dynamic IP address and the IP address changes, you will need to re-register the VAS.

> Note

> > When using the AWC-VAS application, please set NTP to AT-VST-APL.

Selecting "Vista Appliance Storage" from the AWC Plug-in menu will display a list of VAS configured for the AWC Plug-in and a screen for managing the usage of VAS resources (CPU, memory, and disk).
◼ VAS Registration

1. Select "Vista Appliance Storage" from the AWC Plug-in menu.
2. Click "Detect" from the header.
   The "VAS Configuration" dialog box will appear.
3. Wait for a while until the AT-VST-APLs that can be configured as VAS are listed.
4. Select the desired VAS according to the IP address and MAC address.
5. Click on the Configure button.

If the VAS is successfully configured, the VAS information will be displayed in the VAS list on the "Vista Appliance Storage" screen.
Note that in order to record the management status of wireless APs and wireless client history in the configured VAS, it is necessary to set the Floor Map History Setting and Assoc Client History Setting in the "VAS History Mode Setting" and the Retention Period for saving data in the System Setting screen.
◼ Header

Table 1: Header
Item Name | Description
--- | ---
"Import" button | Displays "Import History Data" dialog box. Restores the previously exported VAS history data for the VAS selected in the VAS list. Select ZIP File: Select the previously exported VAS history data (extension: .zip) in the file selection dialog of the web browser. Period: Specifies the period in Coordinated Universal Time (UTC+0) for the data to be restored to the VAS from the exported historical data. For example, if you specify "2021-01-01 00:00" or later, the history data from "2021-01-01 09:00" or later will be imported in Japan Standard Time (UTC+9). To restore the history data after "2021-01-01 00:00" in Japan Standard Time, specify "2020-12-31 15:00" in Coordinated Universal Time. "OK" button: Imports history data. "Cancel" button: Cancels the import of history data.
"Export" button | Displays "Export History Data" dialog box. Download history data from the VAS selected in the VAS list, specifying the period. The format of the file name is "export_vas_atawc-X.X.X_-YYYYMMDDhhmmss.zip". Period: Specify the period for the data to be exported from the VAS, in terms of date and time in Coordinated Universal Time (UTC+0). For example, if you specify "2021-01-01 00:00" or later, the history data from "2021-01-01 09:00" or later will be exported in Japan Standard Time (UTC+9). To export the history data after "2021-01-01 00:00" in Japan Standard Time, specify "2020-12-31 15:00" in Coordinated Universal Time. "OK" button: Exports the history data. "Cancel" button: Cancels the export of history data. Note If the historical data is huge, please narrow the time period so that the exported file is less than 1000 MByte.
"Detect" button | Displays the "VAS Configuration" dialog box. By selecting a storage from the list and clicking on the "Configure" button, the selected storage will be configured as a VAS for the AWC Plug-in and added to the VAS list. X Storage: Displays the total number of VAS that can be configured in the AWC Plug-in. Search Vista Appliance Storage: Filter entries in the list by entering a partial string in the search box. The box will perform incremental search for the entries which have the matching string in one of "IP Address", "Port", or "MAC Address" fields. To remove the filter, delete the string from the Search field and press Enter. Note The search is case-sensitive. IP Address: Shows the storage's IP address. Port: Shows a port number used for communication with the storage. MAC Address: Shows the storage's MAC address. Status: Displays the storage status as Up, Down, or Unstable. Memory: Displays the capacity of the memory built into the storage. Disk Capacity: Displays the disk capacity built into the storage. Available disk space: Displays the free disk space of the storage. "Remove" button: Removes configuration of VAS storage from the AWC Plug-in system. "Configure" button: Performs configuration of storage. "Cancel" button: Discards any changes made to the storage configuration.

◼ VAS List

Table 2: VAS List
Item Name | Description
--- | ---
X Storage | Displays the total number of VAS configured for the AWC plug-in.
X SELECTED | Displays the number of VAS currently selected.
Search Vista Appliance Storage | Filter entries in the list by entering a partial string in the search box. The box will perform incremental search for the entries which have the matching string in either the "IP Address" or "MAC Address" fields. To remove the filter, delete the string from the Search field and press Enter. Note The search is case-sensitive.
IP Address | Displays the VAS IP address.
MAC Address | Displays MAC address of VAS.
Status | Displays the status of the VAS (Up/Down/Unstable).
"Edit" button (pencil) | The "Vista Appliance Storage Setting" dialog box will appear. You can set disk space thresholds for warning and stopping. Warning threshold: Specifies the threshold for displaying warning messages as a value from 1 to 90 (unit: %). If the amount of disk space used exceeds this value, a message will be displayed periodically in the notification section at the bottom of the screen. The default is 80%. Suspend threshold: Specify the threshold for suspending recording to VAS as a value from 1 to 95 (unit: %). When the amount of disk space used exceeds this value, a message will be displayed in the notification section at the bottom of the screen, and recording to VAS will be stopped thereafter. The suspend threshold should be set to a value greater than the warning threshold. The default is 90%. "Save" button: Saves changes to the threshold settings. "Cancel" button: Discard any changes to the threshold settings and close the dialog box.
