10.2 System Performance
Diagnosing CPU slowdowns and overloads
Tasks such as Ethernet packet processing, voice encryption, and call control affect call
processing. To determine how busy the system is at processing calls, the CPU usage of
these tasks is calculated.
Show Status Resource
System resource commands provide information for diagnosing a system that is running
slow or is overloaded:
CP CPU
: The percentage of CPU used for call processing in the last second. The "XX …
" is a graphical indication of the use.
CPLoad
: The average of the percentage of CPU used for call processing in the last
minute. The "XX … " is a graphical indication of the use.
TotCPU
: The percentage usage of CPU since start time. The default start time is when
the system started. Use TotCPU when trying to measure how busy the system is over a
period of time that is longer than 1 minute. Example usages are how much CPU is used
when starting up, or how much CPU is used for an upgrade. Total values of less than
100% may indicate that the startup/upgrade times can be improved.
Resource History Files
A history of the system’s resource usage is stored in CSV files. These files are collected
with system diagnostics and you can manually or automatically schedule the files for
transfer from the controller using ftp.
CPU history file
CPU usage information is collected once per second. This data is written to the disk once
every 15 seconds (bulk write of data to the disk). Writing the data this way reduces the
number of disk accesses and the CPU overhead. A new file is created after 8 hours.
SiloShow (MEM) history file
SiloShow data is collected once every 2 minutes and added to the siloshow resource file.
One file is created per day. Here is a partial example of the MEM file. It contains one of
the system partitions and two process partitions, with two memory snapshots.
