| Description |
|
Sometimes a device provides some information in form of a bitmask. To check some of the bits one could use the trigger function "band". But this function only supports integers why the binary value has to be converted into an unsigned integer. Unfortunately the item value preprocessing doesn't provide such a functionality. So it would be very helpful if this will be implemented. |

For now you you may consider using JavaScript in pre-processing. |

I just tested it with Zabbix 4.4.5 and got it working with the following JS code:
// JavaScript function to convert a bitmask string // into an unsigned integer value function (value) { var regex = new RegExp('^[0-1]+$'); if (value.match(regex) === null) { throw "Value '" + value + "' is not a valid bitmask"; } return parseInt(value, 2); } So I agree that with JavaScript preprocessing Zabbix doesn't need to provide such a function by itself.
