Summary: Getting the exception java.net.ConnectException:
Connection timed out: connect
Product: JMeter
Version: 2.2
Platform: PC
OS/Version: Windows XP
Status: NEW
Severity: critical
Priority: P2
Component: HTTP
AssignedTo: jmeter-dev@jakarta.apache.org
ReportedBy: [EMAIL PROTECTED]
Steps two recreate
-----------------------
Idea of the test
-------------------
To run stress test with 180 users with Ramp-up period of 10 minutes over a 24
hours duration on an application running on a Tomcat Server.
1. Created a Test Plan with the following elements
1. 9 Thread Groups (The above specified 180 users are distributed among
these 9 Threads)
Thus the 9 threads have n1, n2 , ..... n9 number of users/Threads where
n1 + n2 + ... n9 = 180
2. Ramp-up period for each Thread group is calculated as nx * 3.333333
As the over all ramp-up period for all the 180 users is 10 minutes which is
600 seconds, Ramp-up period per user is 600/180 = 3.333333
Thus making the ramp-up periods of the 9 thread groups as n1 * 3.333333 , n2 *
3.333333 ......n9 * 3.333333
When I ran the jmeter, it is throwing the following exception .
