7.7.2 Instance level data The first tiles on the dashboard shown in Figure 7-16 on page 180 show information on the  zCX instance level as seen from within the zCX. The uptime tile just tells since how long the zCX instance is up and running. The containers tile shows how many containers are currently running within this zCX  instance. This tile tells the CPU percent utilized for available CPU’s, from the Li nux perspective. To  interpret this value, keep in mind that you have configured a number of virtual processors to  the zCX instance. This does not mean that your zCX instance has exclusive access to these  processors. It gets only a share of the processors that are available to z/OS, based on the  decisions of the z/OS Workload Manager. The share that z/OS gives to zCX is seen by zCX as 100% CPU and the percentage shown in  the tile is relative to this share. This tile shows the amount of memory within the zCX instance that is currently in use for  processes, as a percentage of all memory available to the zCX instance. This tile shows the percentage of swap memory that is in use. This tile shows the absolute value for the swap space that is in use.
