Hello Zabbix Team,

I have started looking at building a pipeline to process and ingest the history, trends and problems NDJSON files into a more optimized time-series DB.
After building a small POC I encountered one major issue with the current history and trends real-time export protocol.

There exists no type field, so the content of the value field can be anything from a unsigned number to a string.
This is not really optimal as storing unsigned numbers, floats and strings is not the same, on the same note at query time not knowing the type beforehand is also not very optimal.

Would you guys please consider adding a field type to the current history and trends export that will indicate the type of the value.

Type Possible values:

• 0 - numeric float;
• 1 - character;
• 2 - log;
• 3 - numeric unsigned;
• 4 - text.

Regards and thanks for the hard work on the 4.0 release,
Sebastian
