The Edge Filer Status section enables you to monitor the following for the selected edge filer:
Edge Filer Name – The name of the edge filer.
Active Directory Connectivity – Whether the edge filer is connected to Microsoft Active Directory.
Cloud Connectivity – Whether the edge filer is connected to a CTERA Portal.
SMB/CIFS Service Status – The status of the SMB connectivity with the edge filer. More cache information is available under NAS Statistics.
Edge Filer Management Status – The status of the edge filer.
Local Cache – The amount of storage currently in the cache and the amount that is not used. More cache information is available under NAS Statistics.
Zone Sizes – The size of the storage in the folders in all the zones the edge filer can access.
Local Shares – The names of all the local shares and whether NFS has been enabled to access the shares.
Device Location – The location of the Edge Filer. You can zoom in to get a more accurate location, or zoom out, using a mouse scroll or by using the + and – buttons.

The location requires that the edge filer longitude and latitude are saved in the device.

To set the location in the edge filer:

  1. Log in to the edge filer as an administrator.
  2. Select any option under System in the navigation menu (for example System > Network).
  3. In the address bar of your browser, delete the string that appears after the final ":" (for example, network if you clicked Network in the previous step) and type ‘cli‘ in its place.
  4. Press Enter.
  5. The CLI Execution page is displayed.
  6. Enter the following command: set /config/device/geoLocation lat *x* lon *y*
    where x is the latitude for the edge filer location and y is the longitude for the device location.
  7. click GO.

Setting /config/device/geoLocation (Success) is returned.

NAS Statistics

The NAS Statistics section enables you to monitor the following for the selected edge filer:
Data Consumption – The total size available for the cache, with the actual amount of storage currently in the cache and the amount of storage that triggers eviction from the cache. The Data Consumption graph also includes the total amount of data that is used by zones. Click on options from the table to enable or disable showing the information for the selected options. This is especially useful to monitor local cache usage. Click the down arrow displayed to the right of the title when you hover the mouse over the title and then View, to display a larger view of the graph.
Active SMB sessions – The number of SMB sessions actively used, over time. Click the down arrow displayed to the right of the title when you hover the mouse over the title and then View, to display a larger view of the graph.
Local SMB Traffic – The read and write traffic between the gateway and the local PC. Hovering the mouse over the view enables you to accurately display the values at a specific point. Click on options from the table to enable or disable showing the information for the selected options. Click the down arrow displayed to the right of the title when you hover the mouse over the title and then View, to display a larger view of the graph.

Sync Status and Throughput

The Sync Status and Throughput section enables you to monitor the sync status between the edge filer and the portal global file system and the traffic between the edge filer and the portal global file system over time. When syncing the edge filer with the portal global file system, files are downloaded from the portal to the edge filer and uploaded from the edge filer to the portal. When all files have finished being downloaded and uploaded the edge filer and portal global file system are synced.
Number of files left to download – The number of files that the portal global file system needs to download to the edge filer before they are synced.
Number of files left to upload – The number of files that the edge filer needs to upload to the portal global file system before they are synced.
Cloud sync traffic – The read and write traffic between the gateway and the portal. Hovering the mouse over the view enables you to accurately display the values at a specific point. Click on options from the table to enable or disable showing the information for the selected options. When the edge filer and portal global file system are synced the throughput will be 0kBs. Click the down arrow displayed to the right of the title when you hover the mouse over the title and then View, to display a larger view of the graph.

Health Monitoring

The Health Monitoring section enables you to monitor the following for the selected edge filer:
CPU – The percentage of the CPU being used. The color of the usage dials and percentages also indicates the health status. When there is a problem the color changes from green, symbolizing a healthy status, through orange, a warning, to red, symbolizing a problem.
RAM – The percentage of the memory being used. The color of the usage dials and percentages also indicates the health status. When there is a problem the color changes from green, symbolizing a healthy status, through orange, a warning, to red, symbolizing a problem.
CPU over time – A graph showing CPU usage over time, with a breakdown of the usage by components, such as system and user. Click the down arrow displayed to the right of the title when you hover the mouse over the title and then View, to display a larger view of the graph. Hovering the mouse over the view enables you to accurately display the values at a specific point. Click on options from the table to enable or disable showing the information for the selected options.
IOSTAT - Read and write bytes per sec – The I/O over time. Hovering the mouse over the view enables you to accurately display the values at a specific point. Click on options from the table to enable or disable showing the information for the selected options. Click the down arrow displayed to the right of the title when you hover the mouse over the title and then View, to display a larger view of the graph.
IOSTAT - Wait – The amount of time that the CPU is idle during which the system has pending disk read or write requests. Hovering the mouse over the view enables you to accurately display the values at a specific point. Click on options from the table to enable or disable showing the information for the selected options. Click the down arrow displayed to the right of the title when you hover the mouse over the title and then View, to display a larger view of the graph.
