after the installation of ITE Works 4.9.2 and the exchange content pack. I checked all the dashboards to be sure the data was correctly processed and I realized that some panels were blank.
One of them, Inbound Messages - Microsoft Exchange, the panel related to the inbound message volume is empty. looking into the search,
`msgtrack-inbound-messages`|eval total_kb=total_bytes/1024|timechart fixedrange=t bins=120 per_second(total_kb) as "Bandwidth"
I realized that the first macro does not return a column total_bytes so the eval cannot create the new field total_kb so the timechart can not visualize anything.
is there some configuration missing on my side or is it a known bug of the content pack?
