What could be slowing down Datapower?

  • 1.  What could be slowing down Datapower?

    Posted Wed June 09, 2021 11:31 AM
    We are running Datapower version 2018.4.1.6 as a container in our IBM Kubernetes cluster.

    A few days ago my team notified us that the Datapower client has been very slow and the temporal solution has been to scale down then up the deployment, therefore restarting the application.

    While that may work just fine, I'd like to find the root of the problem and fix it, but I don't even know where to begin.

    Any suggestion is welcome, thank you so much!

    Would you know if slowness is in the responses from APIs or in publishing said APIs?

    Otherwise, without any other info we recommend to take some latency logs to find out exactly where that latency is coming from.

    Here are some links to help you with that:
    https://www.ibm.com/support/pages/analyzing-datapower-latency-log
    https://www.ibm.com/support/pages/troubleshooting-datapower-how-set-extended-latency-log-target
    https://www.ibm.com/docs/en/datapower-gateways/2018.4?topic=targets-latency-messages

    If that slowness is due to the backend, the document cache, or parsing, the latency logs will tell you. If you don't know why the latency is showing in a specific action, if it's showing up everywhere, or intermittently then a support ticket is recommended to review the data.

    One reason for the slowness could indicate an internal memory leak of some sort. Since 2018.4.1.6 there have been many memory leak fixes. If that is the case, then upgrading to a newer fix pack might solve the issue.

    Either way, we advise you to open up a support case and to take multiple nbleak reports for some time interval to show what might be the cause.

    Some information on how to set up nbleak can be found here: https://www.ibm.com/support/pages/mustgather-memory-growth-datapower-firmware
