kandi X-RAY | client_golang Summary
This repository generally follows Semantic Versioning. However, the API client in prometheus/client_golang/api/… is still considered experimental. Breaking changes of the API client will not trigger a new major release. The same is true for selected other new features explicitly marked as EXPERIMENTAL in CHANGELOG.md. Features that require breaking changes in the stable parts of the repository are being batched up and tracked in the v2 milestone. The v2 development happens in a separate branch for the time being. v2 releases off that branch will happen once sufficient stability is reached. In view of the widespread use of this repository, v1 and v2 will coexist for a while to enable a convenient transition.

QUESTION
I have a dependency issue with Go and was trying to understand the root cause, hopefully someone can shed some light.
I'm using the Prometheus go client ( https://github.com/prometheus/client_golang ) as a dependency in my Go project. This has a transitive dependency called xxhash, which is discoverable by module aware versions of Go through the virtual path of github.com/cespare/xxhash/v2. It looks like this utility was recently updated to use go modules and this is indicated by its v2 suffix.
I'm running go 1.17.7 in module mode and using the default GoPath. When I try to run go mod tidy it returns the following error.
...ANSWER
Answered 2022-Mar-28 at 20:19The original GOPATH configuration was using a mirror proxy, in the form of Artifactory, for dependency resolution. Checksum collisions prevented pulling in all dependencies. I reverted to proxy.golang.org to resolve the issue

i read the (go)mem info from runtime.MemStats, but cant found rss value, i use m.HeapSys-m.HeapReleased, but found the value is very not like rss ,also i dump the Rss by other tool(github.com/shirou/gopsutil/process), i want to know how to get the rss by memstats, and why m.HeapSys-m.HeapReleased, and m.Sys not equal the rss, so different the value ?
...ANSWER
Answered 2022-Feb-23 at 16:04[H]ow to get golang rss from runtime.MemStats [?]
You cannot. runtime.Memstats doesn't provide that information.
why m.HeapSys-m.HeapReleased, and m.Sys not equal the rss [?]
Because RSS is a completely different metric.
QUESTION
I'm trying to compile kaniko on a raspberry pi.
I don't program in golang, but I was able to compile kaniko successfully a few weeks ago on the same raspberry pi, and even wrote myself a guide of the steps to follow, but now, following the same steps, something is broken.
kaiko requires go, but a more recent version of go then found in the raspberry pi repos, so I download and install go from scratch. go requires go to compile, so I first install it (an older version) from the repos, and then remove it after it's done compiling a more recent version of itself:
Install go:
ANSWER
Answered 2022-Feb-04 at 19:56Based on the comments, my suggestion is to add $HOME/go/bin to the path and use the default GOPATH.
Go mod depends on the bin directory inside the GOPATH. It installs new packages there. The go binary itself can actually reside somewhere else. If you follow these install instruction https://go.dev/doc/install, go itself will actually be in /usr/local/go but the GOPATH is still $HOME/go.
I would also recommend, not involving apt in this at all. This looks like trouble in the form of conflicts with different installations.

I am working my way through a tutorial on go-kit which is using etcd for service discovery. I am using Goland to build a multi-container architecture locally and have just got to the bit where one service (notificator) is being registered in etcd.
All seems fine but when I run:
docker-compose up --build notificator
I get:

QUESTION
I have a Go app that sends data to a prometheus gauge
...ANSWER
Answered 2022-Jan-09 at 15:57The client library will throw this error if the number of labels in With doesn't match the number of labels in NewGaugeVec. So you likely forgot to add labelC: "..." somewhere in your code. You should be able to find the line in the stack trace.
QUESTION
Using github.com/prometheus/client_golang/prometheus library to instrument GO app, for metrics:
In the below code:
...ANSWER
Answered 2021-Oct-26 at 03:07As the package documentation states:
Buckets defines the buckets into which observations are counted. Each element in the slice is the upper inclusive bound of a bucket. The values must be sorted in strictly increasing order. There is no need to add a highest bucket with +Inf bound, it will be added implicitly. The default value is DefBuckets.
Histogram counts observations in buckets. With this declaration, you declare buckets with upper limits of 0.05, 0.1, 0.25, ..., 5, 10, +inf. Each observation will be counted in one of these buckets. For instance, the Observe(0.42) will increment the buckets whose upper limits are >=0.5.

QUESTION
I am new to Prometheus and need help to understand why past metric data is not shown when the target node restarts.
I have set up a Golang web server (target). This server makes use of the Go Prometheus Docs Golang Prometheus client to prepare metrics and exposes metrics on port 3000. Prometheus scrapes data from this target.
Prometheus Config file:
...ANSWER
Answered 2021-Sep-17 at 13:52Looks like you made the hostname part of the metric name. This produces new metrics for every container. The table view only shows metrics that were contained in the most recent scrape for each target.
To fix the issue remove the hostname part from the metric name so the names don't change between restarts. If this is really useful information, add them as a label instead, although that is almost certainly a bad idea.

I am trying to create a REST API using Golang to provide metrics to Prometheus. I already have REST API available that is available on for example: http://localhost:46743/prometheusJobs The API works fine after testing on swagger, I get the response content as followed, for now it's just the sample of text format I got from Prometheus documentation.
This is my Go function to output (provide) the metrics to Prometheus, for now it's just a string as I would like to test first:
