Is it possible to give a custom timestamp in Prometheus for X-axis <https://stackoverflow.com/questions/68095611/is-it-possible-to-give-custom-timestamp-in-prometheus-for-x-axis> ? Example: I* am getting **my_metric_name *152.401 1630134000012 *at metric endpoint but in Prometheus graph, I am getting the value *152.401* when it is scraped, but I want it should be displayed at *1630134000012(Saturday, August 28, 2021, 7:00:00.012 AM) *this time in Prometheus graph.*
Is it possible? if yes, can you please let me know how? Thank you. On Sunday, August 29, 2021 at 11:06:27 AM UTC+5:30 Prince wrote: > Thank you, understood.
