Fixing the Missing Resource Usage Statistics

When logging into the swarmpit manager, the gauges that should be displaying the Disk, Memory and Processor usage might not display at all, and the charts might also appear completely empty. The issue is stems from the swarmpit agents unable to connect back to the swarmpit manager.

In order to resolve this issue, edit the swarmpit agent compose file and set the environment variables HEALTH_CHECK_ENDPOINT and EVENT_ENDPOINT to point to the exposed swarmpit manager port.

For example, if the swarmpit manager exposes a port, in this example 61616:

version: '3.8'
services:
  swarmpit:
    image: swarmpit/swarmpit:latest
    ports:
      - 61616:8080

then the corresponding swarmpit agent compose file should refer to the 61616 port and the FQDN that the swarmpit manager is running on:

version: '3.8'
services:
  swarmpit-agent:
    image: swarmpit/agent:latest
    environment:
      - DOCKER_API_VERSION=1.35
      - HEALTH_CHECK_ENDPOINT=http://manager.tld:61616/version
      - EVENT_ENDPOINT=http://manager.tld:61616/events

where:

• manager.tld is the hostname and suffix of the docker manager and,
• 61616 is the port
