Error in Datadrift Monitor in Azure ML - Analyze existing data

I have created a monitor using Data drift detector in Azure ML.
When I am monitoring it through studio interface using data---->data monitor
it shows below error.
"Failed to load metrics.
Service is temporarily unavailable. Please try again later"
I am unable to see metrics visualization for analyzing data drift.
Even in notebook also it goes in Queue state for long time and don't display metric.

Record Access Control Point BLE explanation - glucose

I'm trying to get glucose measurements from glucose meter (Contour One Plus) with Bluetooth LE. I'm able to connect to device. I don't know how to start with Record Access Control Point. I can discover all of characteristics and services. I am asking for an explanation of the theoretical basis.
So, If I'm connected to the device - the first step is to send a request to RACP that I want to read the data? And what happened next? If Response Code Values send value="success" I should look on Glucose Measurement characteristic?

Example disk space, CPU and / or memory monitoring configuration for Graphite

We are looking for a simple monitoring tool for basic stuff like disk space, CPU, folder sizes, memory usage.
Graphite looks promising. For a demo I want to create some example data to put in Graphite for one or more of such metrics.
What is best way to approach this. I have Graphite running in a Docker. How do I configure Graphite and send some test data to it? For example for
daily disk space metrics
daily folder sizes
hourly CPU
hourly memory
Graphite is not a data collector. From graphiteapp.org:
What Graphite is and is not.
Graphite does two things:
Store numeric time-series data
Render graphs of this data on demand
Graphite is not a collection agent, but it offers the simplest path for getting your measurements into a time-series database. Feeding your metrics into Graphite couldn't be any easier.
You will need a collector, Collectd and Telegraf seem to be popular choices at the moment but there are many others, see list of collectors. Disclosure: I contributed to both projects so might be biased.
Your intervals are very long, Graphite is usually used with way smaller intervals, 10s to 1m. I don't see why it won't work with intervals of hours though. Make sure to configure your storage-schemas.conf accordingly, the default setting is 1m.

Get time from remote time server in R

How can the current timestamp be queried from a remote server (e.g., NIST, windows time server) using R?
I'm guessing it is possible to obtain time using NIST Internet Time Service (https://www.nist.gov/pml/time-and-frequency-division/services/internet-time-service-its), but unsure how this would be done.

sending multiple sensor data on kaa server using C SDK

I need to read multiple sensor data from one single bradboard which is connected to a raspberry pi. We are getting one sensor's data properly, but when we are connecting multiple sensors, we are not sure how to read data from multiple sensors. I am using C SDK of KAA server. i have used the demo_client file to write in log record and dh11.c file to find temreture value. thanks in Advance.
You should modify the code to do separate readings of the sensors samples and upload them to Kaa server as a set of records (this would be the simplest to start with).
Then, you will most probably need to modify the log schema to be able differentiating the telemetry date between sensors.
