Within the Cluster section, you can see the platform monitoring information on the following topics:
To improve graphs usage experience, you can: specify the required interval by adjusting the Start/End Date and clicking Refresh
- hide some graphs by clicking on the appropriate records in the legend
- hover over the chart to view the exact values for the moment
During the platform upgrade, you may need to Activate Maintenance Mode (with the same-named button at the top of the section) to ensure that no user-called processes are interrupted by the performed activities.
After confirmation via the pop-up, the dashboard becomes unavailable, redirecting to your “under maintenance” page; herewith, end-user applications are not affected. Click the button one more time to Deactivate Maintenance Mode.
Cluster Load History
This graph allows to review the load on your cluster:
- RAM of Containers (red line) - memory consumption by containers
- All used RAM (green line) - total memory used
- RAM w/o buffers (orange line) - consumed memory that cannot be reused (RAM of Containers with all memory leaks, overheads for system processes, etc.)
Based on the obtained values, you can estimate how many additional environments your platform can handle. Use the following formula:
Number of Extra Environments = (80% - RAM w/o Buffers) / Average Load Usage per Environment
Here, 80% is the maximum allowed load for all containers. By subtracting the RAM w/o Buffers, you can find out how much the load can be increased.
Average Load Usage per Environment = RAM of Containers / Active Environments
To get Active Environments, navigate to the Cluster > Environments section, filter by the Running status, and see the number at the bottom of the list.
Calculating the Number of Extra Environments due to the screenshots provided above:
RAM w/o Buffers = 46% RAM of Containers = 38% Number of Running Environments = 265 Average Load Usage per Environment: 38% / 265 = 0,14 % Number of Extra Environments: (80% - 46%) / 0,14% = 242
Here, you can analyze the number of performed application deployments (Deploys) and total environments count (Envs) on the platform.
The frame shows the statistics on the total number of nodes for the different container statuses: Running, Stopped, Suspended, and Other.
This diagram shows the stacks, which are currently used on the platform, as well as their respective number. Additionally, you can filter the result by container statuses (Total, Launching, Down, Sleep, Running).
For the convenience of analysis, graphs are grouped by types: custom Docker containers (dark gray), load balancers (green), application servers (blue), databases (orange) and other stacks (light gray).
