      What were you trying to do that didn't work?

      When pcp2openmetrics reads data from an PCP archive on big endian architecture (s390x) the tool crashes, reporting an python exception.

      Please provide the package NVR for which bug is seen:

      pcp-6.2.1-1.el9.s390x

      How reproducible:

      Always

      Steps to reproduce

      1.  Install pcp & pcp-export-pcp2openmetrics packages on s390x architecture
      2.  Start pmcd and pmlogger
      3.  Wait a bit until archive files are populated with some data (i.e. 90 seconds)
      4. Run pcp2openmetrics from the created archive
        pcp2openmetrics -a /var/log/pcp/pmlogger/$(hostname)/ 'kernel.all.load'

      Expected results

      The tool shows the exported data in the openmetrics format

      Actual results

      # pcp2openmetrics -a /var/log/pcp/pmlogger/$(hostname)/ 'kernel.all.load'
      { "//": "Writing 1 archived metrics to stdout..." }
      { "//": "(Ctrl-C to stop)" }
