Unable to display the service name variable in the Grafana Dashboard

[dxsup]

Description:
The variable queried below cannot be displayed on the dashboard:

label_values(increase(kindling_span_trace_duration_nanoseconds_count{}[1m]))

Error Message:

    "error": "cannot fetch time series for \"filters=[{__name__=\\\"kindling_span_trace_duration_nanoseconds_count\\\"}], timeRange=[2025-01-14T06:35:23Z..2025-01-14T07:35:23Z]\": cannot find metric names: error when searching for metricIDs in the current indexdb: the number of matching timeseries exceeds 30000; either narrow down the search or increase -search.max* command-line flag values (the most likely limit is -search.maxUniqueTimeseries); see https://docs.victoriametrics.com/#resource-usage-limits"

The VictoriaMetrics startup parameter -search.maxSeries needs adjustment. The default value is set to 30000, but increasing it to 250000 can resolve this issue. It is advisable to set this parameter to 100000 in the standard deployment.
