Hi. In this video we will introduce the dusk dashboard.
Let's navigate to our dashboard then, uh, it sits, uh,
on the port 8, 8, 8 9 on the local host. As we set it up,
uh, the main and most useful tab is the status tab. As we see here,
what you can see here,
we see here how many gigabytes in total, uh, is used, um,
and what is available in the cluster. We see that just, uh,
by starting the cluster, uh, we already using uh, uh,
more than 600 megabytes of memory.
We see here the memory consumption per worker
in task stream. We are able to see processing of tasks in a time series chart.
In, uh, progress, uh, we will see the overall progress of the computations.
And here in this section we see number of tasks, uh,
which are currently in processing C P U utilization and other
in workers' tab. We see information about our workers
task stream is basically same as in the first tab, uh, status, uh,
the time series chart of task processing.
In, uh,
system tab we have some information about our current state of the system
resources.
The profile tab, uh, is sometimes useful if you want to see which tasks, uh,
are too long to calculate. Or if you want to, Deb, back your calculations
in graph tab,
we'll able to see the dust graph of currently running calculations. But,
uh, if you have a big graph on many partitions rendering,
it may be very slow or it might be not rendered at all.
To explore the das graph is always better, uh,
to do before you run the calculations.
And in info tap we can get more information about locks and exceptions occurred
in each of the worker. These might be sometimes useful when, uh,
some of your workers crashes and you do not know why.
And in Morett Tap we can get even more detailed informations about our cluster
or running graph.
In our next video, we will start to do analytics on the whole data,
and we will see what is happening in the dashboard during calculations.
