Virtual Service Metric - Transaction Daily Counts for "Time Duration = All",
but it is generating a report having last 1 month's data only.
All supported DevTest releases.
By default, VSE transaction metrics holds data for last 30 days. Due to that, you are able to see only 1month data. Below property represents the metrics deletion age.
lisa.vse.metrics.delete.age=30d
If you are using external database and want to store data from more than 30 days, you can add this property in local.properties file on the Registry machine and change the age.
ex: lisa.vse.metrics.delete.age=60d
this will delete metrics data older than 60 days.
Refer to section "Database Maintenance" in the documentation of the DevTest release you are running.
