hi there, i read through some of the suggestions here. Here are some futher steps to troubleshoot:
The simplest explanation for this is that the metric have not yet been collected. They are collected once a day at a time specified in the news config file(2am), by a scheduled task managed by a WAS scheduler.
1) First thing to do is to wait 24hrs to see if they appear following day (or reset the time on the server to 24hrs ahead, which is probably not an option)
2) second thing to check is if you are authorized to access the metrics. The user accessing the metrics needs to be in the J2EE role for "metrics-reader", this should be set to everyone by default. but see here to check (see http://www-10.lotus.com/ldd/lcwiki.nsf/dx/Roles_ic301
3) if the user is in the correct role or the role is set to "everyone", then try to access the metrics via the wsadmin commands: (see here http://www-10.lotus.com/ldd/lcwiki.nsf/dx/Viewing_and_collecting_Home_page_metrics_ic301
if we are sure that 24 hrs has past from the time of install or the time of last attempt to access the metrics, and we still dont see anything via the webpage http://<servername.com:port>/homepage/web/servermetrics or via the wsadmin commands.
5) Then they need to check the DB (if they have access), and determine whether the metrics have been stored within the last 24hrs. To do this they need to look in HOMEPAGE.MT_METRIC_STAT table to see if there are entries collected at approx 2am for each day the server has been running. If there are no metrics for the current date, and the server was online when the metrics are scheduled to be collected, then its probably that there is an issue with the scheduler.
