Dashboard

Status Dashboard

The Dashboard summarizes appliance status

Links

The Status Dashboard provides links to all the main screens of the browser user interface (BUI).

Over 100 visible items on the Dashboard link to associated BUI screens indicated by a boarder or highlighted text that appears on mouse-over.

The sections that follow describe the areas of the Dashboard in detail.

Usage

The Usage area of the Dashboard provides a summary of your storage pool and main memory usage. The pool name may be clicked to change the pool which is displayed on the status screen, should multiple pools be configured on the appliance.

Image
Storage

The name of the pool appears at the top right of the Usage area. To the left is a pie-chart of used and available space. To go to the Shares screen for the pool, click the Storage pie-chart.

Memory

To the left is a pie-chart showing memory usage by component. To go to the Analytics worksheet for dynamic memory usage broken down by application name, click the Memory pie-chart.

Summary Pool Usage
Used
Space used by this pool including data and snapshots.
Avail
Amount of physical disk space available. Space available for file data (as reported in the Shares screen) will be less than this, due to the consumption of filesystem metadata.
Compression
Current compression ratio achieved by this pool. Ratio will display 1x if compression is disabled.
Dedup
Current data deduplication ratio achieved by this pool. Ratio will display 1x if data deduplication is disabled.
Summary of main memory (RAM) usage
Cache
Bytes in use by the filesystem cache to improve performance.
Unused
Bytes not currently in use. After booting, this value will decrease as space is used by the filesystem cache.
Mgmt
Bytes in use by the appliance management software.
Other
Bytes in use by miscellaneous operating system software.
Kernel
Bytes in use by the operating system kernel.

Note that users need the analytics/component create+read authorization to view the memory usage. Without this authorization, the memory details will not appear on the Dashboard.

Services

This area of the Dashboard shows the status of services on the appliance, with a light icon to show the state of each service. Image

Icons

Most services will be green indicating that the service is online, or grey indicating that the service is disabled.

See the icon status section for a reference of all possible states and icon colors.

Links

To go to the associated configuration screen, click on a service name.

The Properties screen appears with configurable fields, restart, enable, and disable icons, and a link to the associated Logs screen for the service.

Hardware

This area of the Dashboard shows an overview of hardware on the appliance. Image

Faults

If there is a known fault, the amber fault Status: Warning icon appears.

Links

To go to the Hardware Maintenance screen for a detailed look at hardware state, click the name of a hardware component.

Activity

The activity area of the Dashboard shows graphs of eight performance statistics by default. The example in this section shows Disk operations/sec. The statistical average is plotted in blue and the maximum appears in light grey.

Dashboard activity: Disk

To go to the Analytics worksheet for an activity, click one of the four graphs (day, hour, minute, second) for the statistic you want to evaluate.

To view the average for each graph, mouse-over a graph and the average appears in the tooltip. The weather icon in the upper-left provides a report of activity according to thresholds you can customize for each statistic on the Status Settings screen.

Graphs
Summary of Statistic Graphs
7 day graph (7d)
A bar chart, with each bar representing one day.
24 hour graph (24h)
A bar chart, with each bar representing one hour.
60 minute graph (60m)
A line plot, representing activity over one hour (also visible as the first one-hour bar in the 24 hour graph).
1 second graph
A line plot, representing instantaneous activity reporting.
Average

The average for the selected plot is shown numerically above the graph. To change the average that appears, select the average you want, either 7d, 24h, or 60m.

Vertical Scale

The vertical scale of all graphs is printed on the top right, and all graphs are scaled to this same height. The height is calculated from the selected graph (plus a margin). The height will rescale based on activity in the selected graph, with the exception of utilization graphs which have a fixed height of 100%.

Since the height can rescale, 60 minutes of idle activity may look similar to 60 minutes of busy activity. Always check the height of the graphs before trying to interpret what they mean.

Understanding some statistics may not be obvious - you might wonder, for a particular appliance in your environment, whether 1000 NFSv3 ops/sec is considered busy or idle. This is where the 24 hour and 7 day plots can help, to provide historic data next to the current activity for comparison.

The plot height is calculated from the selected plot. By default, the 60-minute plot is selected. So, the height is the maximum activity during that 60 minute interval (plus a margin). To rescale all plots to span the highest activity during the previous 7 days, select 7d. This makes it easy to see how current activity compares to the last day or week.

Weather

The weather icon is intended to grab your attention when something is unusually busy or idle. To go to the weather threshold configuration page, click the weather icon. There is no good or bad threshold, rather the BUI provides a gradient of levels for each activity statistic. The statistics on which weather icons are based provide an approximate understanding for appliance performance that you should customize to your workload, as follows:

Dashboard Tasks

Running the Dashboard Continuously

You might experience browser memory issues if you leave the Dashboard screen open in a browser continuously (24x7). The browser will increase in size (memory leaks), and need to be closed and reopened. Browsers are fairly good at managing memory when browsing through different websites (and opening and closing tabs); the issue is that the Dashboard screen is left running and not closed, which opens and reopens images for the activity plots.

To reduce the browser memory growth (which will degrade image rendering performance), disable the memory cache in Firefox, as follows:

  1. Open about:config
  2. Filter on "memory"
  3. Set browser.cache.memory.enable = false
