I would like add threshold line to CA Nimsoft chart
Like in CA APM :
this will facilitate the Monitoring of the different metrics
Those USM graphs are hard-coded and cannot be changed anyway, at least as far as I know. So currently no way to do that.
One way might be to create probe that sends those threshold values to database and then use those in performance graphs or in dashboards.
There is already an idea about this: Put alarm thresholds on the UMP/USM graphs.
