ChaosSearch Storage API - .NET
createObjectGroup API for ChaosSearch
This section provides an example C#/.NET script that enables users to automate the process of creating object groups all the way through initializing indexing.
Create Object Group API
This section shows an example of the createObjectGroup API.
The API request will:
- Create an Object Group
- Set the filter for grouping logs
- Create Live indexing set-up
- Define a retention policy
- Start Indexing
Note
Users must update the
accessKey
andsecretKey
fields with ChaosSearch API keys.
