Postgresql Zabbix error?

Question

PostgreSQL

Comrades, please tell me why item zabbix is ​​displayed

cannot convert value to numeric type

?

Answer 1

YES, this error occurs when the server receives values ​​that do not match the type specified in the item itself.
To see what's wrong, set the type of the value you're getting to text and see what comes up.

Answer 2

Perhaps the value coming to the server does not look like an unsigned numeric. For example, contains a decimal separator or a negative sign.
