Hadoop System Monitor

System monitor displays status summary of all the NameNodes, DataNodes, ResourceManagers and NodeManagers in the QueryIO cluster. Status of nodes can be empty, suspended, ok, warning, error or failure.

Status view provides a quick color-coded view of the state of the configured hosts and all the nodes configured on those hosts. Status is displayed in a graphical view with nodes against time. Displayed status time windows can be changed to 1 hour, 1 day, 7 days, 30 days, 90 days, 180 days or 360 days from the drop down menu.
