MQ Auditor is a solution that allows a company to audit and track all MQ API calls performed by MQ applications that are connected to a queue manager. The API Exit operates with WebSphere MQ v7.0, v7.1, or v7.5 in Windows, Unix, IBM i, and Linux environments. Under WMQ v5.3 and higher, MQA audits the following MQ API calls: MQCONN, MQCONNX, MQOPEN, MQGET, MQPUT, MQPUT1, MQINQ, MQSET, MQCLOSE, MQDISC, MQBACK, MQBEGIN, and MQCMIT. Under WMQ v220.127.116.11 and higher, MQA audits the above calls as well as the following calls: XASTART, XAEND, XAOPEN, XACLOSE, XACOMMIT, XACOMPLETE XAFORGET, XAPREPARE, XARECOVER, XAROLLBACK, AX_REG, and AX_UNREG. Under WMQ v7.0 and higher, MQA also audits the following additional MQ API calls: MQCALLBACK, MQCB, MQCTL, MQSTAT, MQSUB, and MQSUBRQ.
