> However, with this commit ([https://github.com/apache/kudu/commit/e65ea38a4860c007d93ada9c991bccec903a80b1)] , string gauge related to clock_ntp_status is exposed.

> {code:java}
> # HELP kudu_master_clock_ntp_status Output of ntp_adjtime()/ntp_gettime() kernel API call
> # TYPE kudu_master_clock_ntp_status gauge
> kudu_master_clock_ntp_status{unit_type="state"} now:1706665936956760 maxerror:70013 status:ok {code}
> It prevents prometheus operators from collecting prometheus metrics for kudu.
