[Zabbix-users] The value from tomcat using lld can't be saved correctly in Zabbix 3.4.12

[Ming K. <min...@gm...>]

I am trying to use zabbix lld to monitor tomcat 7.0.x in zabbix 3.4.12.

I can see the data is get correctly from agent and server can also receive
the data correctly from log file when I enable debug information. But the
strange issue is: the data can't be saved to database correctly, all these
data are saved as 0 in database.

For example:

The zabbix server got the value of  errorCount  which is 4, but  it was
saved as 0 in history_uint table, this only happens on zabbix lld way.

How could I go about this:

Below is the log info form zabbix_server.log:
