On upgrade, you may not have the new alarm messages which include top processes. Please confirm if the following alarm definitions are listed in the cdm.cfg.
If they are not, add them between the <messages> sections.
text = Average ($value_number samples) total cpu is now $value$unit, which is above the error threshold ($value_limit$unit).Top Processes $processes
level = major
token = cpu_error_processes
i18n_token = as#system.cdm.avrg_total_cpu_above_err_threshold_proc
text = Average ($value_number samples) total cpu is now $value$unit, which is above the warning threshold ($value_limit$unit).Top Processes $processes
level = warning
token = cpu_warning_processes
i18n_token = as#system.cdm.avrg_total_cpu_above_warn_threshold_proc
If they are available, we will need to set the CDM Cpu Active alarm.
To do so, open up the cdm probe.
In Setup > Message definitions click the CPU sub tab.
For High threshold be sure that the alarm is CpuErrorProcesses. For the Low threshold, insert CpuWarningProcesses.
