Checking Logs

There are two log files maintained for CentOS Subscription Manager in the /var/log/rhsm directory:

• rhsm.log shows every invocation and result of running the Subscription Manager GUI or CLI

• rhsmcertd.log shows every time a new certificate is generated, which happens on a schedule defined by the certFrequency parameter in the rhsm.conf file.

The rhsm.log log contains the sequence of every Python call for every operation invoked through the Subscription Manager tools. Each entry has this format:

YYYY-MM-DD HH:MM:SS,process_id [MESSAGE_TYPE] call python_script response

The response in the log entry can be very complex, spanning multiple lines, or relatively simply, with just a status code.

Because each log entry in rhsm.log relates to the Python script or function that was called, there can be multiple log entries for a single operation.

Example 14.10. rhsm.log Entry

The entries in the rhsmcertd.log file are much simpler. The log only records when the rhsmcertd daemon starts or stops and every time a certificate is updated.

Example 14.11. rhsmcertd.log Entry
