    Description

      User Impact: Wrong representation of data on Home Dashboard, could create confusion to end user

      It seems with 2.27.0 we have some glitches in the way we show DB Conns and Disk Reads, if you observe the attached image

       

      You will observe 2 issues:

      1) "DB Conns" shows lots of lines for "All", yet only the single metric value for the individual hosts?

      2) "Disk Reads" in this chart show lines with 0B/s? (this is something I have seen in the previous versions too)

       

      STR:

      1) Open PMM 2.27.0 Home Dashboard, and observe the values on the stats panel for the above two metrics.
