Can I use backup gem with whenever in docker?

Environment:

  • Docker version 20.10.10,
  • Docker image: from Ruby 2.7.2
    Gems:
  • Backup: 5.0.0.beta.3
  • Rails: 6.1.5
  • whenever: 1.0.0

In schedule.rb, I have updated the command

every 1.minute do
  command "/usr/local/bundle/bin/backup perform -t db_backup -c /app/Backup/config.rb"
end

If I run the above command manually on docker bash mode, It works fine. However, when it runs from cron, there is an error showing the following:

/usr/local/lib/ruby/2.7.0/rubygems.rb:277:in `find_spec_for_exe': can't find gem backup (>= 0.a) with executable backup (Gem::GemNotFoundException)
    from /usr/local/lib/ruby/2.7.0/rubygems.rb:296:in `activate_bin_path'
    from /usr/local/bundle/bin/backup:23:in `<main>'

May I know what is a proper way for using backup gem with docker?

Azure Servicebus Completed Messages Metric – AVG, Count, Max… why is Count wrong?

I sent 100 messages, they all completed, bot Count is showing incorrect value while Max and AVG total to 100.

I’m trying to understand the aggregation chart for service bus topic messages. The values for completed messages Max and Avg are correct and total to 100, but Count is 0 or 1.

What am I missing?
