Subject: [PATCH 112/115] CONTRIB: Add DP Request analysis script
|
|
|
|
Run this script using stap as root and Ctrl-C to print the summary
|
|
report
|
|
stap -v /usr/share/sssd/systemtap/dp_request.stp
|
|
|
|
This script will use the data provider request probe markers to provide
|
|
elapsed time of each request and more information about the slowest
|
|
request in the summary report.
|
