How to get more verbose logs for CMP Server in RSA Certificate Manager
Detailed logging for CMP Server
Resolution
To get more verbose logging for the Certificate Management Protocol (CMP) Server, update the following configuration file (and then restart RCM services):

  RSA_CM/CmpServer/conf/cmp.conf

Set the following parameters in cmp.conf as shown:

  loglevel=3
  tracedetail=high

The CMP Server logs are found in the following locations:

-  RSA_CM/CmpServer/bin/cmptrace.log   (if tracefile in cmp.conf is set to the default "cmptrace.log")
-  /var/log/messages  (syslog logfile on Linux/Solaris platforms)
-  Windows Event Viewer Application logs on Windows platforms
In addition to the logs generated by RCM CMP Server, using tools such as Wireshark or tcpdump to capture network packets can be helpful in troubleshooting CMP messages (sent between CMP Client and CMP Server) at the protocol level.

For example, network packets captured by Wireshark and saved into a file, say testcapture.pcap, can be reviewed for CMP transactions as follows:
  - open testcapture.pcapng file in Wireshark
  - select an HTTP transaction row reflecting CMP transaction over HTTP, and right click then select decode as (HTTP)
  - apply filter as CMP, it will show the CMP messages

Here's an example of what a CMP transaction may look like:

No.     Time                       Source                Destination           Protocol Length Info
     20 2013-05-30 10:27:18.578356 100.101.44.88         100.101.44.143        CMP      316    PKIXCMP Status=rejection Body=error
