Evaluating Performance
Evaluating Performance
iTP Secure WebServer provides environment variables that can be used for evaluating
the performance of the http daemon with respect to time:
•
TANDEM_PWAY_ALERT_TIME
•
TANDEM_REQUEST_ALERT_TIME
•
TANDEM_SOCK_ALERT_TIME
TANDEM_PWAY_ALERT_TIME
monitors the time taken for setting up a pathway link. A timer starts in the
WebServer when a Pathway link needs to be established, and ends when the link
is granted.
When TANDEM_PWAY_ALERT_TIME is set to a value greater than 0, and the
timer value is greater than the value specified, this EMS alert message is
generated:
Where:
m and n are the time taken, in seconds
w is the gfn number
x is the irp address
The unit of measurement for this environment variable is seconds.
Example:
#
# Configure the httpd server's attributes
#
Server $root/bin/httpd {
...
Env TANDEM_PWAY_ALERT_TIME=1
}
TANDEM_REQUEST_ALERT_TIME
monitors the time taken for processing a HTTP request. A timer starts when the
connection is accepted and ends when the request is processed.
