Bulk Statistic Enhancements
Previous Behavior: CPU and memory related bulkstats were not available at the card-level for MMEMGR tasks for
performance measurements.
performance measurements.
New Behavior: The following information can now be collected:
Total number of mmemgr tasks across all CPUs on this card.
Average percentage of CPU utilization of all mmemgr tasks across all CPUs on this card.
Average percentage of allocated memory utilization of all mmemgr tasks across all CPUs on this card.
Maximum percentage of CPU utilization of the busiest mmemgr task across all the CPUs on this card.
Maximum percentage of allocated memory utilization of the peak mmemgr task across all CPUs on this card.
Performance Indicator Changes
Card Schema
The following bulk statistics have been added to the Card schema to display card-level information for MME Manager
tasks:
tasks:
task-mmemgr-num
task-mmemgr-avgcpu
task-mmemgr-avgmem
task-mmemgr-maxcpu
task-mmemgr-maxmem
CSCup54025 - S1 and SGs associations not equally distributed across
mmemgr tasks
Feature Changes
Delay in Processing Traffic After Restart
Previous Behavior: After an MME reboot or an SGs service configuration change, the S1 and SGs associations were
not equally distributed across available MME Manager processes. On startup, the MME was starting to allocate traffic
to individual MME Manager processes before all MME Manager processes were activated.
not equally distributed across available MME Manager processes. On startup, the MME was starting to allocate traffic
to individual MME Manager processes before all MME Manager processes were activated.
New Behavior: The MME now waits for all MME Manager processes to become available before processing traffic.
