Unable to connect to the IBM MQ queues via the extension plugin

Hi All,

We are trying to monitor the IBM MQ queues via the IBM MQ ActiveGate extension plugin but facing issues only when we use the encryption. Without encryption, we are able to make successful connection to the queue manager and able to retrieve all the metrics.

Dynatrace config error

Could not get data from queue manager: Unable to get data from queue manager XXX01. Could not connect to Queue Manager: Code: MQCC_FAILED, Reason: MQRC_SSL_INITIALIZATION_ERROR

IBM system logs - Error info

AMQ9639: Remote channel 'XXX.XX.SSL.DYNATRACE' did not specify a CipherSpec.

EXPLANATION:

Cause . . . . . : Remote channel 'XXX.XX.SSL.DYNATRACE' did not specify a
CipherSpec when the local channel expected one to be specified.

Though we have specified the same cipher both at the IBM system end and also in Dynatrace configuration still the issue persist - Cipher used - TLS_RSA_WITH_AES_256_CBC_SHA256

Please advise.

Thanks and Regards,

Arish

Hi @diego_morales,

Thanks for your reply, I indeed opened a support ticket but they did mentioned on the less visibility of this issue in the past. So thought of posting in the common forum to get more insights.
