- MustGather information for CRL (Certificate Revocation List) problems
- MustGather information for NLS / UTF-8 problems
- MustGather information for Certificate problems
- System and web server information MustGather tool
Other diagnostic information
- Diagnosing problems in environments with third-party modules
- Using IBM HTTP Server V6.1 diagnostic capabilities with IBM® WebSphere®
Application Server
- Using IBM HTTP Server diagnostic capabilities with WebSphere
Application Server (for releases older than V6.1)
- preparing for possible problems ahead of time
- configuring IHS and the OS to take core dumps
- diagnosing suspected problems with mod_deflate
- getting backtraces from core dumps manually
- web server hangs with IHS V2.0 or above on Solaris
General information
- IBM HTTP Server performance tuning
- Disabling the HTTP TRACE method
- Common questions about IBM HTTP Server
- Descriptions for common error log messages

- mod_prctl - allow core dumps on Linux® V2.4 kernels
- mod_tracepid - get information on the request being processed at the
time of a crash
- mod_net_trace - trace network activity between IHS and the web browser
or other client
- mod_backtrace - automatic backtraces for child process crashes
- mod_whatkilledus - automatic collection of information about the
request which caused a crash
Diagnostic modules for IBM HTTP Server V2.0 and above
Note: IBM HTTP Server V6.0 and V6.1 are compatible with IBM HTTP Server
V2.0. The version number of IBM HTTP Server V6.0 and higher reflects the
release of WebSphere Application Server with which it corresponds. All
information on IBM HTTP Server V2.0 also applies to IBM HTTP Server V6.0
and V6.1, unless stated otherwise.
- mod_prctl - allow core dumps on Linux V2.4 kernels
- mod_net_trace - trace network activity between IHS and the web browser
or other client
- mod_backtrace - automatic backtraces for child process crashes
- mod_whatkilledus - automatic collection of information about the
request which caused a crash
- mod_backdoor - a way for an administrator to send requests to the
server when it is otherwise unresponsive
- mod_mpmstats - monitor server status
All of this documentation is included in the IHSDiag package.
