@mb7132 Hi, thank you for your question. Just to confirm, you’re referring to annotations, right?

First, create new Labels, then add labels to the added hosts. After exporting the hosts as a whole, re-import them into the hosts and find that the Labels are missing. 1432698788 ***@***.*** &nbsp;

@mb7132 Testing has shown that the export/import of tagged monitoring data is functioning normally. Please verify whether your issue is related to this, or check the console for any serialization-related exceptions.

@mb7132 You are a senior software engineer, before answering, please first verify your conclusion against the project's existing issues, pull requests, documentation, and source code references, then explain why your conclusion remains valid.

[Duansg]

@mb7132 Please perform a comprehensive investigation before concluding.

Verification scope:

1. Search all open and closed issues related to this behavior.
2. Search merged and unmerged pull requests that may affect this area.
3. Review the latest implementation in the relevant modules.
4. Review release notes and upgrade guides.
5. Check whether the behavior changed across recent versions.
6. Look for similar discussions in documentation, examples, and test cases.

For each finding, provide:

• Source
• Link
• Relevant evidence
• Why it supports or contradicts the conclusion

If conflicting evidence exists, explain the differences and provide your confidence level.

Sorry, during yesterday's test, I mistakenly thought that the IP:port was also a similar label, and the description was incorrect. After re-importing, the IP address in the "ip:port" tag is lost. You need to click "Edit Monitoring Item" again and finally click "Confirm". You can restore the data to its original state before exporting without having to supplement the original IP information. 1432698788 ***@***.*** &nbsp;
