OSIsoft Cloud Services (OCS) is a highly flexible cloud-based platform that provides scalable, elastic, centralized environment to aggregate data for reporting, advanced analytics, and third-party applications. OCS is powered by OSIsoft's Sequential Data Store (SDS). In this GitHub repo, we provide samples which will help you get started with the OCS API against your OCS instance.

If you are interested in other OSIsoft samples please see OSIsoft Samples.

There is currently one type of sample in the repo:

• Getting Started - OCS focused samples for a task, usually implemented as a simple console app or single page application. There are also base libraries that may be used in other apps.

• This task and code uses services that are currently in preview. If you are interested in this functionality, please contact OCS support.

The official OCS samples are divided in multiple categories depending on the scenario and problem/task, accessible through the following table:

Task	Description	Languages	Test Status
Authentication - Client Credentials	Click for details on this type of authentication	.NET
Authentication - Hybrid Flow	Click for details on this type of authentication	.NET
Authentication - Authorization Code + PKCE	Click for details on this type of authentication	.NET JavaScript PowerBI Python
Types, Streams, and retrieving Data -- WaveForm	Covers some typical operations against the SDS, including client credential authentication, creating, updating, and deleting types, streams and events. This uses a non-time Series Type. Some tasks are different from the other "Types, Streams, and retrieving Data" task, so look at the task readme for details. This is a recommended starting example, and a good a base for all other Tasks. Details	.NET Libraries .NET REST API Java Angular NodeJS Python
Types, Streams, and retrieving Data -- Time-Series	Covers some typical operations against the SDS, including client credential authentication, creating, and deleting types and streams. This sample is based on Time-Series data. Some tasks are different from the other "Types, Streams, and retrieving Data" task, so look at the task readme for details. This is a recommended starting example, and a good a base for all other Tasks. Details	Python DotNet
UOM	Covers the basic functionality of the UOM system on OCS	.NET
OMF Ingress	Covers the basic functionality of configuring and using the OMF Ingress	.NET
CSV to OCS	Shows how to send a basic csv file to OCS using SDS calls	.NET
Grafana	Demonstrates how to build a Grafana plugin that retrieves stream data from Sequential Data Store	NodeJS
BulkUpload	Demonstrates how to build a Bulk Upload utility that sends SDS objects from json files	DotNet
Sample Libraries	These sample libraries are used as the base for the other samples. They are designed to be straightforward implementations of the REST APIs. They are for use in the samples. Details	Java Python	~~~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~~~~~
Data Views	These samples highlight basic operations of Data Views for OCS, including creation, updating, getting data from and deletion of Data Views. Details	Java Python
Data View Jupyter	This sample demonstrates how to utilize OCS Data Views to do some basic data analysis using Python Jupyter Notebook. Details	Jupyter Notebook

~~ These libraries are tested by being used in other apps.

Note: Tests with automated UI browser components (such as Hybrid Authentication, Authorization Code Flow and Angular samples) fail intermittently due to automatation issues.

For OMF to OCS samples please see the OMF repository: OSI-Samples-OMF

A credential file is used in the samples unless otherwise noted in the sample. The name and location of the credential file should be noted in the sample's readme.
Note: This is not a secure way to store credentials. This is to be used at your own risk.
You will need to modify these files locally when you run the samples.

The style guide describes the organization of the repo and the code samples provided. The test guide goes into detail about the included automated tests. The on prem testing document describes the software installed on our internal OSIsoft build agent.

If you have a need for a new sample; if there is a feature or capability that should be demonstrated; if there is an existing sample that should be in your favorite language; please reach out to us and give us feedback at https://feedback.osisoft.com under the OSIsoft GitHub Channel. Feedback.

If your support question or issue is related to something with an OSIsoft product (an error message, a problem with product configuration, etc...), please open a case with OSIsoft Tech Support through myOSIsoft Customer Portal (https://my.osisoft.com).

If your support question or issue is related to a non-modified sample (or test) or documentation for the sample; please email [email protected].
