Zabbix script item HTTP API, data gets truncated

[vicar]

Hi all,

I'm trying to make an HTTP API request using a "script item" and then process it using JS, but Zabbix truncates the data it receives to 65 kilobytes.
Is there a solution to bypass this limitation and process the request in its entirety?

From doc's: https://www.zabbix.com/documentation...alerts/scripts

The return value is limited to 16MB (including trailing whitespace that is truncated); database limits also apply. When data has to pass through Zabbix proxy, it must be stored in the database, thus subjecting it to the same database limits.

Return value limit

The return value limit for receiving data from external sources (such as scripts or other programs) has been raised to 16MB. This affects:

• Agent items system.run[] and vfs.file.contents[]
• Custom agent checks defined in user parameters
• SSH agent, External check, and Script items
• Remote commands

BUT! I do not know if the same changes were made to the API.

Text data limit is 65536 bytes/characters. 1 Creating an item (zabbix.com)
Try to use http-agent and then do preprocessing with script, if that would work?

Hi Zabbixers,

We observed today using Zabbix Server 7.0.5 that indeed the API truncates the data ("lastvalue") at 64k, for example while using "item.get".
So we are asking ourselves the same question as Hamardaban , did the API get the same max size update.
Should we raise a bug request in your opinion ?

Thanks in advance for your advices.
