Cisco Cisco Content Security Management Appliance M1070 Mode D'Emploi

This page also shows a graph that displays the amount of CPU used by different functions, including 
mail processing, spam and virus engines, reporting, and quarantines. The CPU-by-function graph is a 
good indicator of which areas of the product use the most resources on your system. If you need to 
optimize your appliance, this graph can help you determine which functions may need to be tuned or 
disabled.

The memory page swapping graph shows how frequently the system must page to disk, in kilobytes per 
second. 

The system is designed to swap memory regularly, so some memory swapping is expected and is not an 
indication of problems with your appliance. Unless the system consistently swaps memory in high 
volumes, memory swapping is normal and expected behavior (especially on C170 and C190 appliances).  
To improve performance, you may need to add Email Security appliances to your network or tune your 
configuration to ensure maximum throughput.

This graph also indicates a threshold for memory page swapping that is a visual reference only. To adjust 
the position of this line, see 

. You can configure your Email Security appliances to send you alerts 

that will suggest actions that you can take to address capacity issues. 

The resource conservation activity graph shows the number of times the Email Security appliance 
entered Resource Conservation Mode (RCM). For example, if the graph shows 

n

 times, it means that the 

appliance has entered RCM 

n

 times and exited at least 

n-1

 times. 

Your appliances should enter RCM infrequently and only during a very large or unusual increase in mail 
volume. If the Resource Conservation Activity graph shows that your appliance is entering RCS 
frequently, it may be an indication that the system is becoming overloaded.

The All page consolidates all the previous system capacity reports onto a single page so you can view 
the relationship between the different reports. For example, you might see that the message queue is high 
at the same time that excessive memory swapping takes place. This might be an indication that you have 
a capacity problem. You may want to save this page as a PDF file to preserve a snapshot of system 
performance for later reference (or to share with support staff). 

In some graphs, a line indicates the default value that may indicate a possible problem if it is frequently 
or consistently crossed. To adjust this visual indicator, see 

The Email > Reporting > Reporting Data Availability page allows you to view, update and sort data 
to provide real-time visibility into resource utilization and email traffic trouble spots.
