Unspecified value in evar for occurrences

Hi All,

When we are taking occurrences as metrics. we are getting "unspecified" value in report. but when we applied as "instances" as metrics we can't see "unspecified" value in report.
what could be the reason? is it because the evar is expiring on visits and the evar value is persisting on post pages after the hit?


evar97 setting :


launch configuration

Hi @vidhyaak1,

The instances metric that is associated with an evar counts the number of times that evar fires. Occurrences counts all hits.

So for example, you have this visit

Hit 1: evar110 fires

Hit 2: evar110 persists

Hit 3: evar110 is expired

 

You would get a value of 1 for the evar110 instances metric. This is because the evar fired only once, it doesn't count the number of times the evar persists. And the value for the dimension evar110 will be whatever the value of the evar is.

For occurrences, it would give a total of 3, because there were 3 hits. The row with the value of evar110 (dimension) would be 2, because it fired once and persisted once. Then there would be a row for "unspecified" with a value of 1, because there was 1 hit where evar110 wasn't present.

 

In general, it's a good idea to click the filter and deselect "show unspecified" when working with evars, because often the unspecified column will have the most values (depending on what metric your're working with).
