Re: [smila-dev] SMILA ARM performance measurement?

[Stefan Ruppert <sr@xxxxxxxxx>]

Hi Sebastian,

yes, it was this wiki page. Depending on the goals written down there I 
think ARM is the right thing to go.

But as stated there exists only few non-commercial ARM agents. The only 
two non-commercial java based ARM agents I know are TPTP and MyARM. The 
open-arm development seems to be stopped since years.

Another plus for ARM is that more and more standard applications are ARM 
instrumented and thus can help to find bottlenecks in the complete 
toolchain. To name a few:
 * Apache HTTP Server
 * WebSphere
 * Internet Explorer
 * Firefox (coming soon)

SNMP is a way to get some metrics from a running application (server). 
ARM is designed to capture response times for single transactions 
(tasks) within a running distributed application. For example it is 
possible to measure the complete broken down response time of a web page 
visit:

Transaction name             AppName      Response time Status
+ ShowWebPage               WebClient         2.1s       GOOD
  - HTTP Request            WebClient         1.3s       GOOD
    - HTTP Server           WebServer         0.9s       GOOD
      - Application1        AppServer         0.6s      FAILED
        - SQL Query 1       DBServer          0.3s       GOOD
        - SQL Query 2       DBServer          0.1s      FAILED
  - Rendering               WebClient         0.7s       GOOD

For each of such a transaction additional information can be associated 
with the measurement. For example the URI, the Content-Length or SQL 
statement. Each transaction has a state which indicates if the 
transaction was executed successful (GOOD) or not (FAILED, ABORTED).

However SNMP can be used to provide some sort of metrics like mean 
response times of the transactions.

Regards,
Stefan
