Custom labels and metadata

To add custom labels to a host, complete the following steps. Note that these are static labels. To add labels dynamically based on the contents of the processed data, use the processing steps in data flows.

  1. Find the host on the Hosts or the Topology page, and click on its hostname. The overview of the host is displayed.

  2. Select Edit.

    Edit host metadata

    You can add custom labels in <label-name>:<value> format (for example, the group or department a source device belongs to), or a generic description about the host. You can use the labels for quickly finding the host on the Hosts page, and also for filtering when configuring Flows.

    When using labels in filters, processing steps, or search bars, note that:

    • Labels added to AxoRouter hosts get the axo_host_ prefix.
    • Labels added to data sources get the host_ prefix. For example, if you add a rack label to an edge host, it’ll be added to the data received from the host as host_rack.

    On other pages, like the Host Overview page, the labels are displayed without the prefixes.

  3. Select Save.
