@afoninsky

a small feedback based on evaluation of vector in staging (close to production) on mambu.com

In general, I've found it useful and easy to build composable observabity architectures. I expect it will allow us to move from vendor-locks and be more flexible in solutions we are going to do.

I've splitted vector into small microservices, created helm chart and deployed them to kubernetes environment. It's easier to control them in that way and flexible enough. Every service performs a single operation: receives logs from AWS ELB, redirects logs to datadog, converts logs to metrics, expose metrics as prometheus collector, etc.... Also some of vectors acts as agent on external hosts, collecting information and sending it to common queue.

Things I miss, please inform if there is an issue or want me to create one:

ability to expose vector metrics and make them as a part of pipeline (found an issue about it so it's planned)
http endpoints which acts as kubernetes healtchecks, both readiness and liveness
javascript parser (found an issue, looks like a killer-feature to me as I will be able to move 99% of processing logic into vector)
kubernetes operator, in further I want to provide access for other teams so they will be able to create own pipelines using CRDs (will evaluate it later, does not look very complicated to create my own)
reading configs from yaml files, it's useful to generate configs based on template using jsonnet or helm (I think I've seen it planned)

a question: if I use "log_to_metric" transform and later push to "statsd" sync - is it possible to specify metric timestamp? usecase: store events from http logs in past

"That's why we apply widely accepted best practices when it comes to security"
is there any description which practices are applyed, and how? not an issue, but it would help to pass internal security check :)

Is there no TLS support?

Hi, quick question since I couldn't find an issue or any similar issue on the web. I am using the kinesis firehose sink but it seems to be unable to get the stream I defined.

Error:

Jan 22 16:29:36.082 ERROR vector::topology::builder: Healthcheck: Failed Reason: Stream names do not match, got other-independent-stream, expected my-log-stream

Config:

# Set global options

  type         = "file"
  include      = ["/opt/server/queries.log.*"]
  ignore_older = 86400

[transforms.server_query_parser]
  type = "json_parser"
  inputs = ["server_queries"]
  drop_invalid = true

  inputs = ["server_query_parser"]
  region = "eu-west-1"
  stream_name = "my-log-stream"   <---------------
  encoding = "json"
  healthcheck = false

Would anybody know and can give hints what the cause might be?

Hi,

not sure if a bug or I do something wrong. Hopefully somebody can confirm.

The systemd vector service cannot be started because it looks like that the user+group is not created when installing the RPM:

Jan 23 12:04:56 ip-172-31-44-22.eu-west-1.compute.internal systemd[1]: Started Vector.
Jan 23 12:04:56 ip-172-31-44-22.eu-west-1.compute.internal systemd[1]: Starting Vector...
Jan 23 12:04:56 ip-172-31-44-22.eu-west-1.compute.internal systemd[1]: vector.service: main process exited, code=exited, status=217/USER
Jan 23 12:04:56 ip-172-31-44-22.eu-west-1.compute.internal systemd[1]: Unit vector.service entered failed state.
Jan 23 12:04:56 ip-172-31-44-22.eu-west-1.compute.internal systemd[1]: vector.service failed.

After I modified /usr/lib/systemd/system/vector.service and changed the users to root it worked:

8,9c8,9
< User=vector
< Group=vector
---
> User=root
> Group=root

The RPM was installed per docs on amazon linux 2 with following commands:

curl -O https://packages.timber.io/vector/0.7.X/vector-x86_64.rpm
sudo rpm -i vector-x86_64.rpm

I checked the issues but couldn't find a fitting one. Is the RPM supposed to create a new user+group?

@gedkins

There's a couple of us here interested in developing http and TLS source support for Vector (timberio/vector#328 and https://github.com/timberio/vector/issues/1553). We have some code ready! Should we submit everything we have as one pull request or chop it up into pieces (e.g. one for http, one for https, one for documentation, one for the logplex source refactoring)?

hello again
a questions regarded to "stream-based topology": https://vector.dev/docs/setup/deployment/topologies/
1) I see that vector has "kafka" source/sync, so it's possible to implement this topology... but it streams only "logs" events, what about "metrics"?
2) Do you plan to support less-expensive event-streams like "nats streaming server", or vendor-specific like "google pubsub"?

8 replies

3) not related to topology itself - what about 3d part of o11y: you've covered logs and events, are you planning to cover traces somehow?

hey winners, we're in the process of planning out some new goodies for our config spec, so far we have two proposals that aren't necessarily mutually exclusive but we'll likely only pick one to start with. If you have some time check out timberio/vector#1653 and timberio/vector#1679 and give a thumbs up/down on any proposals you like/dislike accordingly.

Andrey Afoninsky

@afoninsky

do you have a list of transforms, sources/syncs which will be introduced in 1.0.0? roadmap or something

Hi All,

I am finishing implementation of influxdb sink and I have one question about integration tests. Where is a correct place to start InfluxDB for integration tests?
It’s ok if i add influxdb-docker image into docker-compose.yml and integration tests from influxdb_metrics.rs use it?

You can check progress of influxdb sink here: https://github.com/bonitoo-io/vector/blob/influxdb_metrics/src/sinks/influxdb_metrics.rs

hello everyone
I have an issue with connecting to kafka from docker

current config:

Hi, I'm from Humio and was giving Vector a whirl today.. I was trying to read from from a Kafka source, after sending nginx logs with the Kafka sink... I get the following error, tried it in RUST_BACKTRACE=full mode but didn't add any additional context... I get this: Feb 15 00:54:42.530 ERROR source{name=kafka type=kafka}: vector::sources::kafka: Kafka returned error error=KafkaError (Message consumption error: NotImplemented (Local: Not implemented))

[sources.kafka]

is my config

this is an MSK cluster running 2.2

Hey @schofield ! Thanks for letting us know. I’ll file an issue and get someone on the team to take a look on Monday. It looks like something simple. My hope is that we can resolve it quickly.

We haven’t tested explicitly with Amazon’s Kafka service, so it might be that, but my assumption is that it shouldn’t matter.

Grant Schofield

@schofield

cool, also I got a strange error regarding humio, there aren't a lot of logs I'm shipping when using the file source but see Feb 15 01:16:26.584 TRACE sink{name=humio type=humio_logs}: tower_limit::rate::service: rate limit exceeded, disabling service

will check back Monday

Oh and the Kafka did work fine with our own kafka connect sink, and kafkacat works...

Binary Logic

@binarylogic

Thanks @schofield, we'll see what's going on with MSK. I've opened timberio/vector#1833 to look into it.

Regarding the rate limit error, you just need to raise https://vector.dev/docs/reference/sinks/humio_logs/#rate_limit_num . Let me know if we should raise the default there.

@schofield

thanks, missed that one, will give it a go

@afoninsky

just noticed:
you've added "loki" sync as a part of the sprint
and it appeared in documentation which is good: https://vector.dev/docs/reference/sinks/loki/
the problem is - there is no information that it's a part of a nightly build, and not a part of latest stable (0.7.2) so it does not work

hello, guys! I use vector as tcp > kafka transport.
some short time after the start, sink stucks, nothing happens, no suspicious messages in broker and vector logs (in debug mode too)

for a litte time before stuck, in vector log disappears sink messages (only source messages remains)

Has anyone encountered this problem?

Hello, I am routing glog file to elasticsearch.

[transforms.add_metadata] 
  type = "lua"
  inputs = ["src"]
  source = """
event['app'] = event['file']:match('/log/(.+)%.INFO')
"""

[sinks.proj_sink]
  type = "elasticsearch"
  inputs = ["add_metadata"]
  host = "http://1.2.3.4:5"
  index = "proj-{{host}}-{{app}}"

The above snippet does not work. The log shows nothing.

However

  index = "proj-{{host}}"

works and msgs have correct app field. Why can't I use {{app}} in index?

Hi all, I'm not able to get the aws_ec2_metadata transform working. It seems to be connecting correctly to the metadata endpoint, but never makes a request. Here's my sample config:

data_dir = "/var/lib/vector"

[sources.stdin]
