| Description |

create a linux server with 0 swap create an item for example system.swap.size[,free]
the item will become unsupported and return system.swap.size[,free] [m|ZBX_NOTSUPPORTED] [Cannot be calculated because swap file size is 0.]
so preprocessing cant be used
i would have expected to have seen the value of 0 as this is what linux returns to me when running free
free -m

Hello! ZBX - is a bug tracker for identifying and fix some issues in Zabbix functionality |

hmm this item is reporting the wrong information literally making unsupported items using up pollers where it should not. Preprocessing should be handled on the proxy or zabbix server site not on the agent. The OS returns the value 0 so agent should imho report 0 as well or an indication that the swap doesn't exist like with a special value not return the items just unsupported for me more a bug then a feature. But if that is what it takes i will open a feature request for it |
