 Description   

I'm creating some scripts that outputs more than 64KB, which is the current size limit of text checks (see ZBX-952). I would suggest to increase this limit to 16MB to match the database field capacity, at least in mysql, which is of type mediumtext (2**24-1 bytes, see http://dev.mysql.com/doc/refman/5.0/en/storage-requirements.html)

Actual for master items that collect prometheus metrics.

Just as another example, kubernetes kube-state-metrics could easily be more than > 64KB

We are going to increase this limit in Zabbix 4.4, stay tuned!

Wow, so fast! Thank!

It seems I misunderstood this feature request. I thought it was about ability to process larger values. I am afraid we won't be able to increase size of the text fields in the DB in Zabbix 4.4. Perhaps later.

Sorry for the confusion.

I thought that limiting the database also affects the processing of dependent data elements. Now I checked on version 4.2 and saw that the data outside 64Kb is being processed normally.
