Before this werk, the unit of a custom graph was configured by selecting from a
pre-defined list of
units. As of this werk, users have two configuration options:
* **First entry with unit**
With this setting, the unit of the graph will be set to the unit of the first entry of
the custom
graph that as a known unit. Metrics and scalars always have a known unit. Constants on
the other
hand do not. For operations, it depends on the type of operation. For example, the unit
of a sum
of metrics is computed by traversing through the elements of the sum and using the first
found
unit. On the other hand, the unit of a product is unknown. If no entry has a known unit,
the graph
will be rendered without a unit symbol.
* **Custom**
This setting opens a sub-dialogue that allows users to customize the graph unit. Users
can select
from multiple notations, set the unit symbol the and the number of decimal places.
When updating to Checkmk 2.4, in most cases, existing custom graphs will be updated
automatically to
retain the currently configured unit. The rare cases where this is not possible will be
set to
"First entry with unit" during the update.
