What exactly does max_traces_per_user mean?

[manojm321]

Hello,

    # Maximum number of active traces per user, per ingester. A value of 0
    # disables the check.
    # Results in errors like
    #    LIVE_TRACES_EXCEEDED: max live traces per tenant exceeded:
    #    per-user traces limit (local: 10000 global: 0 actual local: 1) exceeded
    # This override limit is used by the ingester.
    [max_traces_per_user: <int> | default = 10000]

does user map to service.name?

Hi! user and tenant are used interchangeably in Tempo. A tenant is defined by a header during ingestion, refer to the docs to enable multi-tenancy.

Thanks, can I set a limit per servce.name?

Unfortunately, no. Limits are configured per tenant.
