  • PMM Dashboard is showing N/A or null for all hosts

    New Home page in 1.81 dashboard is showing N/A or null for all hosts. Any timeout value to increase? I can see in PMM Demo all values are listed correctly.

    Thanks

      Hi there, sorry for the delay.
      Can I just check you ran through the troubleshooting list https://www.percona.com/blog/2018/01...t-pmm-metrics/ ?
      Meanwhile, I will see if I can get any more info for you..

        sureshr7 , Stateros - how many Hosts do you have in your installations? and what PMM server parameters (CPU, Memory)
        Also you can use https://yourserver/graph/dashboard/db/prometheus for additional investigation

            I have the same problem with all clients except one which shows up properly on the Home dashboard. If I open the system overview they show correct values for all clients

              pmm-admin list and pmm-admin check-network said everything is ok.
              https://yourserver/graph/dashboard/db/prometheus - also ok, all services UP and ok

                  Yeah , its a bug. I also tested and it works fine as far as FQDN does not have dot "." in between them as "client_name" in pmm.yml file on pmm client machine. Re-install everything with this fix , it should work.
