This chapter describes the CloudFS Map view (CloudFS UI), which lets you see the health of the overall file network.
The CloudFS UI provides a graphical view of all the configured nodes. It displays the current status and allows you to step back in time to see behavior of various statistics.
The following figure shows the CloudFS UI. The UI includes a map image of the geographical area containing the nodes along with custom controls.
When the map is loaded initially (or the CloudFS tab is clicked), the zoom level is adjusted automatically and centered to show all the node markers on the map. You can zoom in and out, pan, change between satellite and map view, or do other map functions.
The map image shows the nodes based on their site location entered in the System Settings section of the WebUI. You can specify a location using address, city, or latitude/longitude. The map places markers on the map at the correct location.
Location of nodes on Map
The location of each node is derived from the information entered in Location field on the Configuration > System Settings page (System Settings).
The node uses the specified location to obtain the corresponding latitude and longitude and stores the information for use in the CloudFS UI. In some cases, however, this process doesn’t work. For example, if the node is in a private cloud, the address might not be translated into latitude and longitude and the node might not be displayed in the correct location on the map.
In this situation, you can obtain the latitude and longitude independently (from a site such as http://www.latlong.net/Show-Latitude-Longitude.html), and specify the values in the Location field on the System Settings page.
The setting must be entered in the format given in the following example, including the square brackets. After the entry is saved, the node is able to use the values to place the node on the map.
Using the CloudFS UI
You can do the following with the CloudFS UI:
- Select nodes
- Select visualization options
- Select a date range
- Event and Alert Playback Bar
- View statistics information
- View alert information
Click Select nodes in the lower right corner of the CloudFS UI to select the nodes to include in the visualization.
Select Visualization Options
Click View in the lower right section of the CloudFS UI to show the available visualization options:
- Alerts. Select to include alerts in the visualization. See View Alert Information.
- Stats. Select to include statistics in the display.
- Individual stats. Select checkboxes for the items you want to include. See View Statistics.
Select a Date Range
By default, the dashboard shows data for the past month, but you can change the start date to be any date within the past month. The end date of the range is always the current date.
- Click the calendar icon in the lower left corner of the page.
- Click a date in the calendar to change the start date.
- Click Apply to save and change the displayed data.
Event and Alert Playback Bar
The playback bar allows you to move through the date range you specified to view statistics and alert information during that period.
- Play/Stop. Click to start or stop playback.
- Loop. Click this icon and then click the Play icon to start a looping playback. Click the Loop icon again to stop the looping.
- Handle. Use the handle to move through the time period manually.
- Alert makers. These indicate alerts that occurred at particular times during the playback period.
Click the icon in the upper left corner of the CloudFS UI to display statistics for the nodes in your visualization. Click a node name to display the statistics for that node. To select the types of statistics displayed for the nodes, use the checkboxes in the View > System Statistics popup (located in the lower right corner of the window).
The statistics are for the time shown in the playback bar. If you keep the Statistics window open and run a playback, you’ll see the statistics change during the playback period.
You can also view statistics by hovering over a location on the map and clicking the node name.
View Alert Information
If you enabled Alerts in System Stats popup, orange alert markers are shown in the playback bar. Each indicates alerts that occurred at that point during the playback period.
Click a marker to display a list of alerts that occurred at that time.
Click an alert message to view additional details about the alert.
