pre-processing regex based on macro or variable in item prototye

[tamas-p]

Hi,

Is there any way to pre-process a return value on some dynamic way in item prototypes?

So I've got a api query which return about disks and bunch of properties.
I have regex to cut out the desired value from the line, but it each item required to have a the ID in the regex to know which device it belongs to...

Exaple regex:

(\S{1,10})\W\W(propertyName).*[.](1)\s[=]\s.{1,10}\W\s(\d{1,16}|[a-zA-Z 0-9]{1,16})

So in each item the red number would represent the disk id and group 4 would return a the actual value of propertyName
I have managed to chuck this into a discovery so it does find the disks and create the items, but currently without manual intervention, it would record the property of each disks in each item (as text).. If I could parameter up a regex in the item prototype, I could cut of the desired value, but I would need to insert in at least the discovered diskID in there.

Is there way with macro or whatever to do that?

Thanks again

Ok, just to answer my own question, it simply can use the discovery values as of

(\S{1,10})\W\W(propertyName).*[.]({#DISKID})\s[=]\s.{1,10}\W\s(\d{1,16}|[a-zA-Z 0-9]{1,16})

Also to add that the the discovery rule was based on JSON return, which returns like:
{ "{#DISKID}":"1" },
{ "{#DISKID}":"2" },
{ "{#DISKID}":"3" },
etc....
