What’s Changed?¶

EnOS 2.1 Release introduces the following behavioral changes.

API¶

For details of changed APIs, log into the EnOS Management Console and click EnOS API > Release Notes from the navigation menu.

Model Service¶

API	What’s Changed
Search Thing Model	The field `tags` in the `expression` supports arithmetic operators “exists” and “not exists”.

Connection Service¶

API	What’s Changed
Get Device	4 new parameters are supported in Device struct to indicates the latest time when a device was updated: `measurepointLastUpdate`, `eventLastUpdate`, `attributeLastUpdate` and `featureLastUpdate`.
Search Device	A new field `deviceTags` is supported in `expression`.
Search Product	A new field `deviceTags` is supported in `expression`.

Alert Service¶

API	What’s Changed
Create Alert Rule	A new parameter `triggeringDelayTimer` is supported in request body to indicate the time of delaying the alert triggering.
Search Active Alert	The response parameter `value` in the `ActiveAlert` struct supports recording the measurement point value when `triggeringDelayTimer` starts counting. The field `tag` in the `expression` supports arithmetic operators “exists” and “not exists”.
Search Alert Rule	A new parameter `triggeringDelayTimer` is supported in `AlertRule` struct to indicate the time of delaying the alert triggering.
Search History Alert	The function is changed to query historical alarms in the last three months. The response parameter `value` in the `HistoryAlert` struct supports recording the measurement point value when `triggeringDelayTimer` starts counting. The field `tag` in the `expression` supports arithmetic operators “exists” and “not exists”.
Update Alert Rule	A new parameter `triggeringDelayTimer` is supported in `alertRule` struct to indicate the time of delaying the alert triggering.
Aggregate Active Alerts	The field `tag` in the `expression` supports arithmetic operators “exists” and “not exists”.

Asset Tree Service¶

API	What’s Changed
Search Asset Node	In request body, use `expression` parameter to replace previous parameter `filter`.

TSDB Data Service¶

API	What’s Changed
Get Asset AI Raw Data	A new parameter `withQuality` is supported in request URI to get the quality indicator.
Get Asset Generic Data	A new parameter `withQuality` is supported in request URI to get the quality indicator.
Get Asset Raw Data by Time Range	A new parameter `withQuality` is supported in request URI to get the quality indicator.
Get Asset DI Data	Interpolation is supported in getting the asset status (DI) data. When no data is found at the query start time, the latest DI data in the past 30 days will be returned with the time stamp of the query start time.
Get Asset Raw Data by Time Range	A new parameter `orderBy` is supported in the request URL, which can be used to sort the response results by a certain field.

EnOS Edge¶

Service/Function Module	Before	After	Impact
Template	You must send all measurement point data that EnOS Edge collected to EnOS Cloud	You can choose not to send a measurement point data to EnOS Cloud.	Configure Upload Type in EnOS Edge > Template > Edit Template > Points Mapping .
Template	Only system timestamp can be used for a measurement point.	You can use OEM timestamp for a measurement point and use system timestamp only if there is no OEM timestamp.	Enable Using OEM Timestamp in EnOS Edge > Template > Edit Template > Points Mapping .
DPF	You cannot deduplicate status word.	You can now deduplicate status word.	N/A
DPF	Only the system timestamp of a measurement point can be received.	Both system and OEM timestamps can be received.	N/A

Device Connection¶

Optimization for “per-product secret” authentication protocol¶

Original Behavior	Current Behavior
After EnOS issues the `deviceSecret` to a device, no `device_secret` will be issued regardless of whether the device is activated by the `deviceSecret`.	A device can still request and get the `deviceSecret` if the device does not carry a `deviceSecret` for activation after EnOS issues a `deviceSecret` to the device. This improvement is mainly applicable for the scenario where the `deviceSecret` is missing.

Serach Function Enhancement¶

Service/Function Module	Before	After
Product Management	You can search for a product only by product key.	You can also use model or product name to search for products.
Device Management	You can search for devices only by device key.	You can also use model, asset ID, device name to search for devices.
Asset Tree	Searching by device key and model supports only exact matching.	Fuzzy matching is supported for searching by device key or model.

Other Function Enhancement¶

Service/Function Module	Before	After	Impact
Model, Product, Device, Asset Tree	Only em dash (-), underscore (_), period (.), and colon (:) are supported in model, device, product, asset tree, and asset names.	Slash (/), asterisk (*), plus (+), number sign (#), and space ( ) are also supported in in model, device, product, asset tree, and asset names.	None
Device	Users can only use model, device name, device key, and asset ID to search for a device.	Product name can be used to search for device and exporting devices of the same product in batch is supported.	None
Device	Users have to define sample data for, start, stop, or delete simulators one at a time.	Defining data sample for, start, stop, and deleting simulators in batch are supported.	None
Alert	Users have to create severity, type, content, and rule one at a time.	Up to 10000 entries can be uploaded in batch for severity, type, content, and rule by editing and uploading template.	None
Alert	Users have to use content and rule ID for searching.	Added support of using model for searching content and rule, and exporting selected search results.	None

Data Asset Management¶

Stream Data Processing¶

Starting from this release, the AI aggregation template is renamed window aggregation template. Supports aggregation for numeric types of data.

Data Cleanup¶

Added “Cleanup Failure” status of TSDB data cleanup jobs. When a data cleanup job fails, it can be restarted through the Restart icon in the Operations column. Data that is already deleted by the job cannot be restored.

Application Enablement¶

API Management¶

Added the message prompt for the interruption of API staging process.
Deleted the message box for response parameters.
When importing APIs, API Management will check whether the imported APIs already exist. Existing APIs cannot be imported again. This improves the efficiency of API migration.

Enterprise Container Platform¶

Starting from this release, the EnOS Service Hosting Center is renamed to Enterprise Container Platform.
When creating an application, either Deployment or Stateful Set for a container can be created, i.e. it is not allowed to create both.
Optimized the pipeline creation process.
The default values of CPU Maximum and Memory Maximum of Resource Quota when creating Deployment and Stateful Set are changed to “1.0 Cores” and “1.0G” respectively.
The Number of Files when creating a Storage container is changed to 10 million.
Docker Registry is selected by default when creating a pipeline.
Optimized the password display operation in the service directory, and modified the password creation rules to support for uppercase/lowercase English letters, numbers and !@#$%^&*/-, with no password displayed during editing.
Type is selected by default when creating a Service.
Type is selected by default when creating Redis, Mongo and MySQL.
Pod IP is not displayed before until the health check is completed for Redis, Mongo and MySQL.
