LDAP-UX Integration Performance and Tuning Guidelines

Appendix A dirload Tool
The script on the following page can be used to monitor load on your directory server for an extended period of
time. To install this file on your directory server, cut and paste the script below. It will be saved under
/tmp/dirload. This script is designed to monitor load from LDAP-UX clients. It assumes that only LDAP-UX
clients are accessing the directory server being measured. It does not make an accurate measurement of requests
from other types of applications.
