celery-exporter's Issues

How to see exposed metrics.

After attaching to the celery-exporter container via docker exec command, I put the Rabbit MQ url and run the following

celery-exporter -b "amqp://guest@rabbitmq:5672"

In the Readme, it's written

If you then look at the exposed metrics, you should see something like this:
`

celery_tasks_total{name="my_app.tasks.calculate_something",namespace="celery",queue="celery",state="RECEIVED"} 0.0
celery_tasks_total{name="my_app.tasks.calculate_something",namespace="celery",queue="celery",state="PENDING"} 0.0
celery_tasks_total{name="my_app.tasks.calculate_something",namespace="celery",queue="celery",state="STARTED"} 0.0
celery_tasks_total{name="my_app.tasks.calculate_something",namespace="celery",queue="celery",state="RETRY"} 0.0
celery_tasks_total{name="my_app.tasks.calculate_something",namespace="celery",queue="celery",state="FAILURE"} 0.0
celery_tasks_total{name="my_app.tasks.calculate_something",namespace="celery",queue="celery",state="REVOKED"} 0.0
celery_tasks_total{name="my_app.tasks.calculate_something",namespace="celery",queue="celery",state="SUCCESS"} 1.0
celery_tasks_total{name="my_app.tasks.fetch_some_data",namespace="celery",queue="celery",state="RECEIVED"} 3.0
celery_tasks_total{name="my_app.tasks.fetch_some_data",namespace="celery",queue="celery",state="PENDING"} 0.0
celery_tasks_total{name="my_app.tasks.fetch_some_data",namespace="celery",queue="celery",state="STARTED"} 1.0
celery_tasks_total{name="my_app.tasks.fetch_some_data",namespace="celery",queue="celery",state="RETRY"} 2.0
celery_tasks_total{name="my_app.tasks.fetch_some_data",namespace="celery",queue="celery",state="FAILURE"} 1.0
celery_tasks_total{name="my_app.tasks.fetch_some_data",namespace="celery",queue="celery",state="REVOKED"} 0.0
celery_tasks_total{name="my_app.tasks.fetch_some_data",namespace="celery",queue="celery",state="SUCCESS"} 7.0
...

`

How to get this ? Do we have to configure anything in celery worker container ?

Get number of celery workers by queue name

I have 2 different kinds of celery workers each executing tasks from its own queue. Can I get celery_workers count for each worker type(using queue name) by celery-exporter?

RabbitMQ Resets connection

I am facing the following issue with my connection to rabbitmq, the connection is stable at works at the beginning but after that it gets reset.

I believe this has to do with heartbeat pings not getting back to rabbitmq and it cutting the connection.

Similar issue:
Polyconseil/aioamqp#96

Process hangs during startup if Redis instance is not responding

I tried to connect celery-exporter to a Redis based broker, which sits behind a firewall. Since i didn’t have my IP added to the firewall, i couldn’t connect to the Redis instance, which made celery-exporter hang without any response. After i added the IP to the firewall, it came up fine.

I would have expected a timeout error after a while, or at least an “Initial fetching of registered tasks”.

Metric data always shows pending and is not changing to success after completion. It only shows pending state.

I am using celery=5.0.2 and django=2.2.2. I have enabled these two settings in my django app: CELERY_WORKER_SEND_TASK_EVENTS = True
CELERY_TASK_SEND_SENT_EVENT = True

I am using the docker image and passing my broker url as args to it. It is able to connect to my broker and I can run it locally on port 9540 but only the pending counter is updating and doest change later.

Task thread can fail and not recover resulting in zero value metrics

Hi,

We run celery-exporter inside Kubernetes and communicate against a redis-broker.

We sometimes see failures like so:

[2020-05-21 13:21:01,747] root:INFO: Starting HTTPD on 0.0.0.0:9540                                       
[2020-05-21 13:21:02,842] task-thread:ERROR: Connection failed

Which looks like it hits some kind of issue, and then enters the recovery loop:

https://github.com/OvalMoney/celery-exporter/blob/master/celery_exporter/monitor.py#L63

At this point, the container remains up (and can communicate with it), but the metrics returned are always zero, so it does not capture events after this issue.

The underlying issue is not that important, and could be anything (i.e. network issue, pod restart, new rollouts etc).

I think either within this app, or within the scope of Kubernetes, there is an expectation of self-recovery.

If this issue were to propagate up to the parent process, and the main process died, that would actually be a good thing (at least for K8s), since the pod would get restarted.

If I restart the pod manually (which is my only workaround at the moment), things work as expected.

My thinking is that https://github.com/OvalMoney/celery-exporter/blob/master/celery_exporter/monitor.py#L64 is not working as expected...

Pip installation failed with crates.io error

Hi,
I'm using python 3.6 .when I try to install celery-exporter, it gave error in build rust
"Rust compiler not found".
I installed setuptools-rust. Rerun pip command for celery exporter Again I got error cargo not found.
Installed rust and cargo rpm using yum in CentOS. In build rust ,now it's trying to read subprocess.command(["cargo","manifest-metadata","cargo.toml"]) exit with error code 1 . It tries to reach crates.io/index github.com url.
My server is not having internet access. How shall I proceed?.

There is a internal artifactory for python packages but no repository for crates.io

celery_workers always 0.0

Hi. I'm using celery==5.1.2 and your exporter from branch for ver5, exporter was build in docker, connected fine, but metric celery_workers always show 0 count, can somebody help me with this?

Queue name in the Prometheus metrics

Hi, thank you for this project, I have a question please about the exposed metrics.

I'm trying the exporter locally, without any tasks I can check the celery_tasks_total metric in the Prometheus dashboard and I can see my tasks:

celery_tasks_total{instance="celery_exporter:9540",job="celery_exporter",name="info",namespace="celery",queue="default",state="STARTED"}

The queue as you can see is default, for this task the value is right because I have changed my default task name from celery to default, but the problem is that all the other tasks also have the queue as default even thought each task has a queue with the same name:

celery_tasks_total{instance="celery_exporter:9540",job="celery_exporter",name="process",namespace="celery",queue="default",state="STARTED"}

As you can see, here the queue should be process for my task process but it's default, that's also the case for other tasks.

Also when I delay new tasks to be processed, these metrics stay the same with their values of 0 and new metrics show up for every task but this time with the queue value of undefined with the correct number of tasks:

celery_tasks_total{instance="celery_exporter:9540",job="celery_exporter",name="info",namespace="celery",queue="undefined",state="STARTED"}

So what could be wrong here? I have my queues defined as the task_queues Celery option, and for all the tasks except the default one I'm setting the queue argument of the @app.task() decorator.

Best regards,

receiving celery_worker_tasks_active = 0

celery_worker_tasks_active{hostname="worker2"} 0.0
celery_worker_tasks_active{hostname="worker1"} 0.0

Hey! i get 0 active tasks even though there are currently 10. it seems to me that celery-exporter monitoring is not updating active tasks often enough

Task's queue is 'undefined'

By some reason the output is the following:

celery_tasks_total{name="local.update_record",namespace="celery",queue="local_develop",state="STARTED"} 0.0
# skipped
celery_tasks_total{name="local.update_record",namespace="celery",queue="undefined",state="STARTED"} 1.0

All recorded tasks have queue as "undefined".

Build binary wheels

I'd love to be able to install this without having a rust compiler. Have you thought of building binary manylinux wheels and pushing them to PyPI?

Update python build to work with rust compiler from stable release channel

I'm getting build failures when running pip install celery-exporter on a system with rustc 1.39.0 compiler installed on it:

    error[E0554]: #![feature] may not be used on the stable release channel

    warning: pyo3 was unable to check rustc compatibility.
    warning: Build may fail due to incompatible rustc version.

I'd like to use this library but don't think I can if it is not based on a rust environment from the stable release channel.

Is there a reason why this package relies on a rust environment based on nightly-2019-06-20?

Task send vs receive latency

I noticed that the latency monitoring seems to only account for the time between when a worker receives a task and when it starts the task.

However, it would be great if we could also track the latency from when a task is published. The task-sent event is disabled by default, but if enabled on a cluster, it could be valuable in understanding where scheduling latencies are occurring.

Remove `maturin sdists` in travis publish

Following maturin guide here during build phase it should build sdist if not explicitly disabled.

ATM with the latest release 1.5.0 I can see source distribution on PyPi https://pypi.org/project/celery-exporter/#files even if maturin sdist command was broken.

@xrmx @MRoci I think we could remove it or I'm missing something?

Can we have an environment variable for passing --transport-options ?

Similar to all these options:

DEFAULT_BROKER = os.environ.get('BROKER_URL', 'redis://redis:6379/0')
DEFAULT_ADDR = os.environ.get('DEFAULT_ADDR', '0.0.0.0:8888')
DEFAULT_MAX_TASKS_IN_MEMORY = int(os.environ.get('DEFAULT_MAX_TASKS_IN_MEMORY',
                                                 '10000'))
DEFAULT_QUEUE_LIST = os.environ.get('QUEUE_LIST', [])

Can we have an environment variable for passing transport options ?

Release version 1.4.1

Hi there!

Would you be open to releasing a new patch version of the lib/image with any bugfixes since the last release? I can see there's a 'latest' tag in the Docker Hub from October 2020 but no corresponding tag, and it'd be awesome if there was a tagged release associated with it.

Thanks for the useful project!

Executable binary for isolated hosts

Is there a way to make an executable binary for isolated hosts?
The problem is that I need to run it on hosts that don't have internet connection, so I can't install a bunch of dependencies and such.
I've tried to build it via pip on the same architecture machine that had internet access, moved the binary across but it doesn't work.

Metric showing in progress tasks and celery_task_total inconsistency

Hi,

The readme seems to suggest that the celery_tasks_total is a gauge but it's implemented as a Counter.

Is there any plan to "revert" this to a gauge showing the inflight tasks in each state currently? Or even introduce a new metric that covers this use case.

The default histogram buckets are on the order of miliseconds and seconds. For celery if you have long running tasks like re-encoding a video and then uploading gigabyte sized files it puts all the tasks in the INF bucket. A solution could be to add a config.py which lets you customize the histogram. The super nice part is that it'd be pretty easy to put the file as a ConfigMap in Kubernetes or build the container with the extra file(basically as an overlay).

I'm happy to put up a pull request for this would be useful for the community.

Python 3.9 wheel support (pypi)

Hello,

was doing upgrade today to python version 3.9 and it looks like wheel file for Python version 3.9 is not present in pypi: https://pypi.org/project/celery-exporter/#files
Not sure if this is by intent, perhaps 3.9 version is not yet supported and therefor missing wheel file?
Installation/compilation can be performed manually by installing rust on machine, but it would be so much nicer to have it as wheel file.

By looking at travis.yaml and tox.ini it seems that 3.9 version is working fine and build on travis is passing.
Please let me know if i can help anyhow in building wheel file for python 3.9
Tnx!

Can't reference to SSL broker

celery-exporter/celery_exporter/core.py

Line 29 in 497c8d8

self._app = celery.Celery(broker=broker_url)

can't set broker_use_ssl if necessary

Ex. if i use RabbitMQ with TLS i should pass the broker_url and tell Celery to use TLS/SSL with the mentioned arg.
celery-exporter -b "pyamqp://<user>:<pwd>@<host>:<port>/<vhost>" --enable-events

No response after running it with Docker

Hi!

I am using this exporter to get the queue length from celery and autoscale in K8 using Prometheus based pipeline.

After running this command.
docker run -it --rm ovalmoney/celery-exporter
There is no output. Kindly see below image.

I have no clue what is happening. Can anyone help me regarding this or tell me how to use this exporter with docker-compose ?

Not sure/understanding why, is it a key created by the exporter and removed or other things ?

Best regards,

Installation of pip package fails on Debian / Ubuntu stable versions

I'm trying to install the package on debian stable like so:

# Create venv
mkvirtualenv -p python3 celery-exporter

# Install rust version manager
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
source $HOME/.cargo/env

# Install rust nightly (celery-exporter wants either nightly or dev)
rustup toolchain install nightly
rustup default nightly

# Install exporter pip requirements
sudo apt-get -y install python3-dev python-dev
pip install setuptools-rust

# Install exporter
pip install celery-exporter

However the last command fails with:

+ pip install celery-exporter

FUTURE OF CELERY-EXPORTER

Hi guys,

I'm sorry but I'm not working for OvalMoney anymore and since then I lost my write privileges to this repository.
I don't think OvalMoney has any interest in contributing to this project in the future.

Queue length metrics ?

Hiya,

I'm just wondering how easy/hard would it be to implement number of tasks in a queue (to detect whether celery is choking for example) ? Let me know what would be potentially needed pls and if I'd be able to pull it together in a PR as a layman. Greets

Missing or Invalid Metrics?

I was searching for a celery exporter and came across this lib. A user on the SO post that lead me here claims there are missing and/or invalid metrics. Has anyone else experienced this? Attaching screenshot
