The locations of the following libraries referenced in this procedure depend on the OS and Web server version you are using:
libpassthrough.so for the Sun Web server on UNIX platforms, passthrough.dll on Windows
mod_loadbalancer.so for the Apache Web server on UNIX platforms, mod_loadbalancer.dll on Windows
sun-passthrough.dll for Microsoft IIS (Windows only)
Check the plug-in version with the following command (UNIX only):
Web Server 6.0 or Web Server 6.1
strings libpassthrough.so | grep BuildId |
Apache Web server
strings mod_loadbalancer.so | grep BuildId |
Verify the checksum of the plug-in library using one of the following commands:
cksum
elfdump —k
sum
md5sum
Edit and add the relevant configuration files to generate more debug information.
Sun Java Web Server 6.0
Edit the server-root/web-identifier/config/magnus.conf file, adding the following line at the end:
LogVerbose on
Edit the server-root\web-identifier\config\magnus.conf file, adding the following line at the end:
LogVerbose on
Sun Java Web Server 6.1
Edit the server-root/web-identifier/config/server.xml file, setting the loglevel property of the LOG element to FINEST.
Edit the server-root\web-identifier\config\server.xml file, setting the loglevel property of the LOG element to FINEST.
Apache
Edit the server-root/config/httpd.conf file, setting the LogLevel option to debug.
Edit the server-root\confighttpd.conf file, setting the LogLevel option to debug.
Edit the server-root\web-identifier\config\loadbalancer.xml file and set the require-monitor-data property to true.
<property name="require-monitor-data" value="true"/> |
This generates debug information for the Load Balancer plug-in in the Web server error log.
