Working with Clusters

Click the Cluster option to see a set of diagrams with the following information:

Cluster Load History

  • RAM of Containers (red line) - real used memory by containers
  • RAM w/o buffers (orange line) - consumed memory that can't be reused (RAM of containers with all memory leaks and different overheads for system processes etc)
  • All used RAM (green line) - used memory with buffers



You can find out how many environments can be added due to the available extra load using the following formula:

Number of extra environments = (80% - RAM w/o buffers) / Average load usage per environment

80% is the maximum possible load of containers.
By subtracting the RAM of containers w/o buffers from these 80% you can get to know how much the load can be enlarged.

The Average load usage per environment can be calculated in such a way:

Average load usage per environment = RAM of containers / Active environments

To get the number of Active environments, navigate to Cluster > Environments. Sort environments due to the Running status and see the total number of displayed environments.


Example:


Calculating the Number of extra environments due to the screenshots provided above:

RAM w/o buffers = 30%
RAM of containers = 20%
Number of running environments = 99
Average load usage per environment: 20% / 99 env = 0,2 %


Number of extra environments
(80% - 30%) / 0,2% = 250 env

So we can say that due to our example 250 more environments can be created.
