Host Tags (the number in the property name (e.g. tags.tag.0) references tag order in the tag evaluation list)
Evaluation type 0 evaltype 0 - (default) And/Or;
2 - Or.
Tag name 1 tags.tag.0 Any string value.

Parameter Tag name required if configuring Tags.
Operator 0 tags.operator.0 0 - Contains;
1 - Equals;
2 - Does not contain;
3 - Does not equal;
4 - Exists;
5 - Does not exist.

Parameter Operator required if configuring Tags.
Tag value 1 tags.value.0 Any string value.

Parameter Tag value required if configuring Tags.
Columns (see below)
Order 0 order 2 - (default) Top N;
3 - Bottom N.
Order column 0 column Column numeric value from the configured columns.
Host count 0 count Valid values range from 1-100.

Columns

Columns have common parameters and additional parameters depending on the configuration of the parameter Data.

For all parameters related to columns the number in the property name (e.g. columns.name.0) references a column for which the parameter is configured.

The following parameters are supported for all columns.

Parameter type name value
Name 1 columns.name.0 Any string value.
Data

(required)
1 columns.base_color.0 Hexadecimal color code (e.g. FF0000).
Item value

The following parameters are supported if Data is set to "Item value".

The first number in the Thresholds property name (e.g. columnsthresholds.color.0.0) references the column for which thresholds are configured, while the second number references threshold place in a list, sorted in ascending order. However, if thresholds are configured in a different order, the values will be sorted in ascending order after updating widget configuration in Zabbix frontend (e.g. "threshold.threshold.0":"5""threshold.threshold.0":"1"; "threshold.threshold.1":"1""threshold.threshold.1": "5").

Parameter type name value
Item 1 columns.item.0 Valid item name.
Time shift
