Importing historic tools knowledge into AWS IoT SiteWise


AWS IoT SiteWise is a managed service that helps clients accumulate, retailer, arrange and monitor knowledge from their industrial tools at scale. Prospects usually have to carry their historic tools measurement knowledge from current techniques corresponding to knowledge historians and time collection databases into AWS IoT SiteWise for guaranteeing knowledge continuity, coaching synthetic intelligence (AI) & machine studying (ML) fashions that may predict tools failures, and deriving actionable insights.

On this weblog submit, we are going to present how one can get began with the BulkImportJob API and import historic tools knowledge into AWS IoT SiteWise utilizing a code pattern.

You need to use this imported knowledge to achieve insights via AWS IoT SiteWise Monitor and Amazon Managed Grafana, practice ML fashions on Amazon Lookout for Tools and Amazon SageMaker, and energy analytical purposes.

To start a bulk import, clients have to add a CSV file to Amazon Easy Storage Service (Amazon S3) containing their historic knowledge in a predefined format. After importing the CSV file, clients can provoke the asynchronous import to AWS IoT SiteWise utilizing the CreateBulkImportJob operation, and monitor the progress utilizing the DescribeBulkImportJob and ListBulkImportJob operations.


To comply with via this weblog submit, you have to an AWS account and an AWS IoT SiteWise supported area. If you’re already utilizing AWS IoT SiteWise, select a unique area for an remoted surroundings. You might be additionally anticipated to have some familiarity with Python.

Setup the surroundings

  1. Create an AWS Cloud9 surroundings utilizing Amazon Linux 2 platform
  2. Utilizing the terminal in your Cloud9 surroundings, set up Git and clone the sitewise-bulk-import-example repository from Github
    sudo yum set up git
    git clone
    cd aws-iot-sitewise-bulk-import-example
    pip3 set up -r necessities.txt


For the demonstration on this submit, we are going to use an AWS Cloud9 occasion to signify an on-premises developer workstation and simulate two months of historic knowledge for just a few manufacturing strains in an car manufacturing facility.

We are going to then put together the info and import it into AWS IoT SiteWise at scale, leveraging a number of bulk import jobs. Lastly, we are going to confirm whether or not the info was imported efficiently.

AWS IoT SiteWise BulkImportJob Architecture

A bulk import job can import knowledge into the 2 storage tiers supplied by AWS IoT SiteWise, relying on how the storage is configured. Earlier than we proceed, allow us to first outline these two storage tiers.

Scorching tier: Shops regularly accessed knowledge with decrease write-to-read latency. This makes the recent tier ultimate for operational dashboards, alarm administration techniques, and some other purposes that require quick entry to the current measurement values from tools.

Chilly tier: Shops less-frequently accessed knowledge with larger learn latency, making it ultimate for purposes that require entry to historic knowledge. As an example, it may be utilized in enterprise intelligence (BI) dashboards, synthetic intelligence (AI), and machine studying (ML) coaching. To retailer knowledge within the chilly tier, AWS IoT SiteWise makes use of an S3 bucket within the buyer’s account.

Retention Interval: Determines how lengthy your knowledge is saved within the sizzling tier earlier than it’s deleted.

Now that we realized concerning the storage tiers, allow us to perceive how a bulk import job handles writes for various eventualities. Check with the desk beneath:

Worth Timestamp Write Habits
New New A brand new knowledge level is created
New Current Current knowledge level is up to date with the brand new worth for the supplied timestamp
Current Current The import job identifies duplicate knowledge and discards it. No adjustments are made to current knowledge.

Within the subsequent part, we are going to comply with step-by-step directions to import historic tools knowledge into AWS IoT SiteWise.

Steps to import historic knowledge

Step 1: Create a pattern asset hierarchy

For the aim of this demonstration, we are going to create a pattern asset hierarchy for a fictitious car producer with operations throughout 4 totally different cities. In a real-world situation, it’s possible you’ll have already got an current asset hierarchy in AWS IoT SiteWise, during which case this step is non-compulsory.

Step 1.1: Evaluate the configuration

On this step, for demonstration objective, we are going to simulate two months of historic knowledge for 4 stamping presses throughout two manufacturing strains. In a real-world situation, this knowledge would sometimes come from supply techniques corresponding to knowledge historians and time collection databases.

The CreateBulkImportJob API has the next key necessities:

  • To determine an asset property, you have to to specify both an ASSET_ID + PROPERTY_ID mixture or the ALIAS.On this weblog, we will probably be utilizing the previous.
  • The information must be in CSV format.

Observe the steps beneath to generate knowledge in line with these expectations. For extra particulars concerning the schema, seek advice from Ingesting knowledge utilizing the CreateBulkImportJob API.

  1. Evaluate the configuration for knowledge simulation.
    cat config/data_simulation.yml
  2. Run python3 src/ to generate simulated historic knowledge for the chosen properties and time interval. If the entire rows exceed rows_per_job as configured in bulk_import.yml, a number of knowledge recordsdata will probably be created to help parallel processing. On this pattern, about 700,000+ knowledge factors are simulated for the 4 stamping presses (A-D) throughout two manufacturing strains (Sample_Line 1 and Sample_Line 2). Since we configured rows_per_job as 20,000, a complete of 36 knowledge recordsdata will probably be created.
  3. Confirm the generated knowledge recordsdata beneath knowledge listing.SiteWise historical CSV data files
  4. The information schema will comply with the column_names configured in bulk_import.yml config file.

Step 2.2: Add historic knowledge to Amazon S3

As AWS IoT SiteWise requires the historic knowledge to be out there in Amazon S3, we are going to add the simulated knowledge to the chosen S3 bucket.

  1. Replace the info bucket beneath bulk_import.yml with any current non permanent S3 bucket that may be deleted later.
  2. Run python3 src/ to add the simulated historic knowledge to the configured S3 bucket.
  3. Navigate to Amazon S3 and confirm the objects had been uploaded efficiently.SiteWise Bulkimport historical data in S3

Step 3: Import historic knowledge into AWS IoT SiteWise

Earlier than you possibly can import historic knowledge, AWS IoT SiteWise requires that you just allow Chilly tier storage. For added particulars, seek advice from Configuring storage settings.

You probably have already activated chilly tier storage, think about modifying the S3 bucket to a brief one which will be later deleted whereas cleansing up the pattern sources.

Observe that by altering the S3 bucket, not one of the knowledge from current chilly tier S3 bucket is copied to the brand new bucket. When modifying S3 bucket location, make sure the IAM function configured beneath S3 entry function has permissions to entry the brand new S3 bucket.

Troubleshoot frequent points

On this part, we are going to cowl the frequent points encountered whereas importing knowledge utilizing bulk import jobs and spotlight some doable causes.

If a bulk import job isn’t efficiently accomplished, it’s best follow to seek advice from logs within the error S3 bucket configured in bulk_import.yml and perceive the foundation trigger.SiteWise BulkImportJob Error Bucket

No knowledge imported

  • Incorrect schema: dataType doesn't match dataType tied to the asset-property
    The schema supplied at Ingesting knowledge utilizing the CreateBulkImportJob API needs to be adopted precisely. Utilizing the console, confirm the supplied DATA_TYPE supplied matches with the info sort within the corresponding asset mannequin property.
  • Incorrect ASSET_ID or PROPERTY_ID: Entry isn't modeled
    Utilizing the console, confirm the corresponding asset and property exists.
  • Duplicate knowledge: A worth for this timestamp already exists
    AWS IoT SiteWise detects and routinely discards any duplicate. Utilizing console, confirm if the info already exists.

Lacking solely sure components of knowledge

  • Lacking current knowledge: BulkImportJob API imports the current knowledge (that falls inside the sizzling tier retention interval) into AWS IoT SiteWise sizzling tier and doesn’t switch it instantly to Amazon S3 (chilly tier). Chances are you’ll want to attend for the following sizzling to chilly tier switch cycle, which is at present set to six hours.

Clear Up

To keep away from any recurring costs, take away the sources created on this weblog. Observe the steps to delete these sources:
