The idea behind it is described in detail in https://github.com/prometheus/client_golang/issues/320 . This commit also updates the example given in promhttp/instrument_server_test.go , which nicely illustrates the benefit of this change. So far, currying could be emulated by creating different metric vec's with different values in their ConstLabels. This was quite difficult to grasp - which is essentially what was done in the example mentioned above. Now that this use case can be solved without ConstLabels, we can safely declare ConstLabels as rarely used. (Perhaps we can deprecate them entirely one day, but I'll take a raincheck on that when the changes of v0.10 have materialized.) This commit thus also updates the ConstLabel doc comments in the various Opts. (It contained fairly outdated stuff anyway.) |

Prometheus Go client library
This is the Go client library for Prometheus. It has two separate parts, one for instrumenting application code, and one for creating clients that talk to the Prometheus HTTP API.
This library requires Go1.7 or later.
Instrumenting applications
The
prometheus
directory
contains the instrumentation library. See the
best practices section of the
Prometheus documentation to learn more about instrumenting applications.
The
examples
directory
contains simple examples of instrumented code.
Client for the Prometheus HTTP API
The
api/prometheus
directory
contains the client for the
Prometheus HTTP API. It allows you
to write Go applications that query time series data from a Prometheus
server. It is still in alpha stage.
Where is model
, extraction
, and text
?
The model
packages has been moved to
prometheus/common/model
.
The extraction
and text
packages are now contained in
prometheus/common/expfmt
.
