IHS Access Log for WebSphere Commerce sites

While doing the production server trouble shooting for many of the issues, the investigation starts from the IHS access logs. But the default IHS log configuration will not give you enough details for troubleshooting and diagnose the root cause server. It will be more complicated when there is a cache layer exists as well. The following log level will give you all the information needed for trouble shooting. The log will provide the output in a csv format so that it will be easier for further processing if needed

LogFormat  "\"%h\",\"%{%Y-%m-%d-%H.%M.%S.000000}t\",%p,\"%H\",\"%m\",\"%U\",\"%q\",%>s,\"%b\",\"%{WAS}e\",%D,\"%{CACHED_RESPONSE}o\"" common

h - Client IP
t - Access Time
p - Port
H - Protocol
m - Request method
U - URL without query String
q - Query String
>s - Status of the request
b - size of response in bytes
{WAS}e - Name of the WAS server
D - Time taken to serve request in micro seconds
{CACHED_RESPONSE}o - The request served from dyna cashe or not

If we want to shoe the request and response cookie values then we could use the following parameter for a short period of time

{Cookie}i - Cookie request header
{Set-Cookie}o - Cookie with response
