## What's changed? Added JEXL basic validation and supplemented optimized keywords. For reference: [JEXL Syntax](https://commons.apache.org/proper/commons-jexl/reference/syntax.html) 、[Api Docs](https://commons.apache.org/proper/commons-jexl/apidocs/org/apache/commons/jexl3/JexlContext.html) Therefore, it is not difficult to see that the following rules must be satisfied: 1. Must start with a-z, A-Z, _ or $. 2. Whitespace is a separator and cannot appear within an identifier. 3. Keywords are reserved characters and cannot be used as variable names or property names when performing operations. There are currently templates that do not match JEXL rules, which may cause threshold expressions to behave abnormally. For example: <img width="1508" height="530" alt="Snipaste_2025-10-16_16-38-03" src="https://github.com/user-attachments/assets/11896063-3e70-4a3c-a61a-a581d40360a7"; /> Modification details: 1. Supplement and refine retained keyword information 2. Added space validation 3. Added initial character validation 4. Refine the validation script and modify all existing templates containing erroneous fields. ## Checklist - [x] I have read the [Contributing Guide](https://hertzbeat.apache.org/docs/community/code_style_and_quality_guide) - [x] I have written the necessary doc or comment. - [x] I have added the necessary unit tests and all cases have passed. ## Add or update API - [ ] I have added the necessary [e2e tests](https://github.com/apache/hertzbeat/tree/master/e2e) and all cases have passed. > app-kafka_client.yml <img width="1506" height="863" alt="Kafka" src="https://github.com/user-attachments/assets/912214ed-2008-4338-aca2-bbd1f196e7f9"; /> <img width="1507" height="660" alt="Kafka_threshold" src="https://github.com/user-attachments/assets/a84f5790-cb8d-4e32-8983-b6e009c210e5"; /> <img width="1509" height="713" alt="Kafka_threshold1" src="https://github.com/user-attachments/assets/0ff09492-3fd3-48df-b7fd-f29570a3cb3e"; /> > app-pulsar.yml <img width="1511" height="578" alt="Puslar" src="https://github.com/user-attachments/assets/75507b18-5a9f-4038-b14a-a394b64a6a50"; /> <img width="1507" height="621" alt="Puslar_1" src="https://github.com/user-attachments/assets/84930db0-98b1-4b81-8bf2-e6700cd1d69e"; /> <img width="1511" height="620" alt="Puslar_threshold" src="https://github.com/user-attachments/assets/576ad2a2-5c59-4ba1-972b-405763ca9389"; /> -- This is an automated message from the Apache Git Service.
