Hi Manish:
I looked at the APM database table:
create table ts_concurrent_sessions (
ts_id int8 not null unique,
ts_session_count int4 not null,
ts_creation_date timestamp with time zone not null,
ts_year int2 not null,
ts_month int2 not null,
ts_week int2 not null,
ts_day int2 not null,
ts_hour int2 not null,
version_info int8 not null,
ts_soft_delete bool not null,
primary key (ts_id)
);
This looks like across all monitored applications is the way this is measured and I don't think concurrent session has a business application in the pull-down. So based on what I am seeing , the answer to your questions now.
Please let us know if we can consider this thread answered or if there are follow-up questions,
