Short answer: No.

The Go `time.Time` type includes the time zone. It can use any time
zone. The library will then use the capabilities of the Go `time.Time`
type to convert it into Unix-time, as required by the exposition
format, which is independent of time zones.

This here is the mailing list to discuss development of the various

Thank you. Got It.

for NewMetricWithTimestamp(time.Time,metric)  Is it compulsory that the 
time should be in UTC?

In general you shouldn't set the timestamp for a metric at all. There 
are very few use cases where it should be used, with the main one being 
when connecting another scrape based metric system to Prometheus (e.g. 
CloudWatch).


For everything else you set the metric to the latest value (for a gauge) 
and it will then update Prometheus during the next scrape. If you must 
know the exact time of the last event (for example to alert if events 
stop happening) you'd have a gauge whos value is that timestamp. But in 
none of those situations would you set the metrics timestamp.

So that means in the Prometheus graph the data will be getting displayed 
from the time of scraping and at a regular intervals (scrape interval).
Example: my_metric  1669.574 1630299163151(data and it's timestamp). So 
this data 1669.574 will be displayed at starting scrape time not at this

 However it is sounding like Prometheus may not be the right system 
 depending on what you are trying to do. Prometheus is a metric system, 
 which works by sampling the current state of a system at regular time 
 periods, meaning the exact timestamp doesn't generally matter.

 It sounds like you are instead wanting to record events - things that 
 happen at a specific period of time, not at a regular frequency. For that 
 use case you should look at an event store - something like Elasticsearch, 
 InfluxDB or a standard relational or no-SQL database.

Re: [prometheus-developers] Adding timestamps to Gauge Metric

[Stuart Clark]

The key things you just said were "event" and "logs", both of which are not the 
metrics that Prometheus is designed for. Now it is possible to convert 
events/logs into metrics, but this sounds different to what you are wanting. 
Metrics created from logs would have regularly scraped metrics (where no 
timestamp is included) which might contain a counter of the number of events or 
the value of the last event (or maybe even a gauge containing the last 
timestamp of the event). These are then perfect for alerting when events stop 
happening, happen too often or produce values outside of allowed parameters.

If instead you are wanting to be able to store individual data points when 
events happen (which might be at any point, not aligned with a regular scrape 
interval) as it sounds then you want something different to Prometheus. You can 
use a standard SQL or no-SQL database (such as MySQL or DynamoDB) or a time 
series database (such as InfluxDB or Timescale DB). For many of the different 
options you can visualise them using Grafana, which allows you to show data 
from both Prometheus and your event store

Re: [prometheus-developers] Adding timestamps to Gauge Metric

[Prince]

So let's suppose we are monitoring an event in such a way that the logs of 
this event are in a file and there is some value for that event and 
correspondingly time at when we got that value.
So in the Prometheus graph we can not show the value at that time 
Because I have a similar situation where I have a value and timestamp for 
that value. But when the Prometheus server starts running it shows the 
value at the current time not at it's a timestamp.

Re: [prometheus-developers] Adding timestamps to Gauge Metric

[Ben Kochie]

Yup, Prometheus is a monitoring system, not a general use time-series
database.

Specifically, Prometheus has a "look back window" where Prometheus will
take the timestamp of your query and look back in time for samples to match.

This is fundamental to how PromQL works.

So no, what you are asking for is not possible. PromQL graph queries base
the X-axis on the input parameters of the range query. The start, end, and
step.

See the documentation on the API:
https://prometheus.io/docs/prometheus/latest/querying/api/#range-queries

 So NewMetricWithTimestamp() returns a Metric interface object that you
 can then emit from a Collector's Collect() method. See this example from
 cadvisor:
 https://github.com/google/cadvisor/blob/19df107fd64fa31efc90e186af91b97f38d205e9/metrics/prometheus.go#L1931-L1934

 You can see more usage example here:
 https://sourcegraph.com/search?q=context:global+prometheus.NewMetricWithTimestamp&patternType=literal

 In general, it seems like you are building an exporter (a process
 that proxies/translates existing values into the Prometheus format, in your
 case those existing values are coming from a file), so you are not
 instrumenting the exporting process itself, and thus you probably don't
 want to use the "NewGauge()" / "mygauge.WithLabelValues().Set()" functions
 that are for direct instrumentation of a process. Instead, you'll want to
 implement a Collector interface that just returns a set of proxied metrics,

Re: [prometheus-developers] Adding timestamps to Gauge Metric

[Stuart Clark]

That very much depends on whatever tool you are using to display graphs.

However it is sounding like Prometheus may not be the right system depending on 
what you are trying to do. Prometheus is a metric system, which works by 
sampling the current state of a system at regular time periods, meaning the 
exact timestamp doesn't generally matter.

It sounds like you are instead wanting to record events - things that happen at 
a specific period of time, not at a regular frequency. For that use case you 
should look at an event store - something like Elasticsearch, InfluxDB or a 
standard relational or no-SQL database.

Re: [prometheus-developers] Adding timestamps to Gauge Metric

[Prince]

Is it possible to give a custom timestamp in Prometheus for X-axis 

?
Example: I* am getting **my_metric_name *152.401 163013412 *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 *163013412(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.

 Hi,

 You should be able to use the NewMetricWithTimestamp() function for 
 this: 
 https://pkg.go.dev/github.com/prometheus/client_golang/prometheus?utm_source=godoc#NewMetricWithTimestamp

 Note that client-side timestamps should only be used in exceptional

 there and mostly show empty graphs). If that is not the case, consider

Re: [prometheus-developers] Adding timestamps to Gauge Metric

[Prince]

Thank you, understood. I have used the following:

in Collect()
 *  t := time.Date(2021, time.August, 28, 07, 0, 0, 12345678, time.UTC)*
*s := prometheus.MustNewConstMetric(c.metric, prometheus.GaugeValue, 
float64(s.value))*
*ch<- prometheus.NewMetricWithTimestamp(t,s)*

*I am getting **my_metric_name 152.401 163013412 *(both things the 
value and timestamp), but I am not getting this timestamp in the x-axis of 
prometheus graph. Can You please let me how can I get that timestamps in 
The x-axis of prometheus graph?

Re: [prometheus-developers] Adding timestamps to Gauge Metric

[Julius Volz]

So NewMetricWithTimestamp() returns a Metric interface object that you can
then emit from a Collector's Collect() method. See this example from
cadvisor:
https://github.com/google/cadvisor/blob/19df107fd64fa31efc90e186af91b97f38d205e9/metrics/prometheus.go#L1931-L1934

You can see more usage example here:
https://sourcegraph.com/search?q=context:global+prometheus.NewMetricWithTimestamp&patternType=literal

In general, it seems like you are building an exporter (a process
that proxies/translates existing values into the Prometheus format, in your
case those existing values are coming from a file), so you are not
instrumenting the exporting process itself, and thus you probably don't
want to use the "NewGauge()" / "mygauge.WithLabelValues().Set()" functions
that are for direct instrumentation of a process. Instead, you'll want to
implement a Collector interface that just returns a set of proxied metrics,
as outlined here:

*
https://pkg.go.dev/github.com/prometheus/client_golang/prometheus#hdr-Custom_Collectors_and_constant_Metrics
* https://prometheus.io/docs/instrumenting/writing_exporters/#collectors

Re: [prometheus-developers] Adding timestamps to Gauge Metric

[Prince]

Thank you, As I understood the  NewMetricWithTimestamp() takes two 
parameters one the time and the other one is metric. So as my metric name 
is go_duration, so I did this :

*1st way:*
*go func(){*
go_duration.WithLabelValues("type").Set(12345.678)
prometheus.NewMetricWithTimestamp(time_var, go_duration )
*}()*

*2nd way: *
*go func(){*
prometheus.NewMetricWithTimestamp(time_var,go_duration.WithLabelValues("type").Set(12345.678))
*}()*


Using 1st way not getting the timestamp only values are getting scarped.
Using 2nd way getting error as: 
"go_duration.WithLabelValues("type").Set(12345.678) 
used as a value"

Re: [prometheus-developers] Adding timestamps to Gauge Metric

[Julius Volz]

Hi,

You should be able to use the NewMetricWithTimestamp() function for this:
https://pkg.go.dev/github.com/prometheus/client_golang/prometheus?utm_source=godoc#NewMetricWithTimestamp

Note that client-side timestamps should only be used in exceptional
circumstances, and if you still expect those timestamps to be regularly
updated (because otherwise Prometheus will just collect a dot here and
there and mostly show empty graphs). If that is not the case, consider
omitting the client-side timestamp and instead sending a metric that
includes the last-update timestamp in its sample value (like the
node_exporter does for the mtime metric in its "textfile" collector module:
https://github.com/prometheus/node_exporter/blob/b6215e649cdfc0398ca98df8e63f3773f1725840/collector/textfile.go#L38
)

Julius

[prometheus-developers] Adding timestamps to Gauge Metric

[Prince]

Hi everyone, I am new to prometheus. I am using type Gauge. I wanted to get 
the timestamp along with the value. It will be great if anyone can help on 
this.
example:
go_duration.WithLabelValues("type").Set(12345.678)

so here collector is getting only 12345.678, I am reading this data from a 
file where along with the vale there is a corresponding timestamp is there. 
I want that too.
