Services chart

Admin panel

On the Services chart, you can monitor two types of services:

  • Metadata services (MDS). The number of all disks with the metadata role. Ensure that at least three MDSes are running at all times.
  • Chunk services (CS). The number of all disks with the storage role.

Typical statistics may look like this:

The green color on the chart indicates active services. If some time periods are highlighted in a different color, you can hover over them to check the services status. To see a list of service statuses, refer to Monitoring node disks.

Command-line interface

Use the following command:

vinfra cluster overview

For example, to view the information about the storage services in the cluster cluster1, take a look at these lines from the command output:
