Can 'lastlogsize' be changed by API?

[RogerQea]

Hi, everyone.

I tried to use 'item.update' method to set 'lastlogsize' to 0. However, it did not return an error, but the value did not change.

Meanwhile, my zabbix's version is 2.2.14. I tried to do this on bash with curl. I think I can guarantee that I gave the right command, since I can change other values like 'descriptions' with equivalent command.

Is this a bug? Has it been fixed in newer versions? Or is zabbix designed to behave like this.

Could anyone help me with this please?

additional information

The following text is what shown on my shell when I tried to change "lastlogsize" and "description"; it can be clearly found that "description" has been successfully changed from "c1" to "c1test_writable", but "lastlogsize" is still "6923" not "0" . I hope this can provide some detail information and might be helpful. Is it really a bug? Should I ask this questions in the bug report session?
