Metrics and observability

Every dedicated project on comes with live infrastructure metrics, which provide an overview of the production environment’s resource usage.

Within the management console, metrics for your production environment can be found under the “METRICS” tab shown below.

Metrics dashboard

Available on this page are usage metrics for CPU, RAM, and persistent disk for each of the three hosts in your N+1 configuration, as well as an average across them. For each property, usage that crosses an 80% threshold will trigger a warning message displayed on this dashboard. Usage that crosses 90% will result in a critical message displayed.

Measurements are taken for each metric every ten seconds, and there is a taskbar in the top right-hand corner from which you can select a window to view those samples. You will be able to zoom-in to observe individual samples, but in the primary three views (the last 15 minutes, the last hour, and the last day) averages are shown over larger intervals depending on the view.

View Sample average Example
The last 15 minutes (15m) 10 seconds 10:00:10, 10:00:20, 10:00:30
The last hour (1hr) 1 minute 10:00, 10:01, 10:02
The last 24 hours (24hr) 20 minutes 10:00, 10:20, 10:40, 11:00

From each view, you can zoom onto a smaller sample interval by dragging your cursor over that area on the graph.

The sample interval then changes based on the range you choose to zoom in on.

View Sample average
< 30 minutes 10 seconds
30 minutes - 2 hours 1 minute
2 - 5 hours 5 minutes
5 - 24 hours 20 minutes

From the taskbar you can also filter out individual hosts.

Metrics - sampling

Standard Dedicated environments will have a single cluster of three hosts, with each additional cluster adding at least three additional hosts to the project. Dedicated environments with two clusters have a split architecture, and their metrics are displayed in two separate groups: one for the web hosts that handle web requests and one for the service hosts that handle database, cache, and other services.

Metrics - sampling

Each metric will display thresholds on the available resource after those resources used by the operating system have been subtracted (except for CPU). The images below have been taken from a single dedicated cluster, and can be an example for illustrating this difference.

Example: reading metrics 

The reference project shown in the sections below has configured a single Python application, and three services: Elasticsearch, Redis, and MariaDB. It has been granted 4GB of memory and 2 vCPUs per host based on its plan. Persistent disk for each service have been configured as such:

  • python: 1024MB, allocated to the mount exports
  • elasticsearch: 1024MB
  • mysql: 2048MB
  • redis: no disk defined


For the project, 2 vCPUs have been allocated per host, and in this case that value is displayed as the upper limit for the CPU metric.

Metrics - CPU


RAM measures overall RAM usage (including user, kernel, and buffer groups), displaying a percentage over the RAM available for each host. For this example, each host has been granted 4GB of memory, while the upper limit in the plot below is listed as 3.62GB. 0.38 GB of memory are in use by the operating system, leaving the remaining 3.62GB available to the host.

Metrics - RAM


Disk represents that amount of persistent disk granted by the plan over all services and mounts, which for production Dedicated environments is 50GB.

Metrics - disk

For each host, you will be provided first with disk metrics from the root (/) folder. Disk utilization here does not count against the 50GB set aside for your plan, but rather infrastructure disk which can include the /tmp directory. It has been included here in the dashboard so that you can keep track of build artifacts you write to /tmp, making sure that they do not get too large and fill up.

On the right are two directories specified for the mysql service (shown again below) and the exports mount. In this case, only 20GB out of the total 50GB have been allocated for the environment, and you can keep track of the defined space here.
