Hi, I am running into an issue with vector that it's not closing file descriptors on rotation of files via logrotate (file source). These are nginx logs. This is is happening for already rotated *.access.log.1 files which are rotated a second time, to *.access.log.2.gz. These deleted file descriptors accumulate over a period of time and we have to restart vector to fix disk alerts. Fingerprinting is currently configured with checksum strategy, with file source configured to check only for *.access.log file

Hi all, how do you think of using vector as a forwarder of analytic events from Kafka to Kinesis? Though docs says vector is not for non-observability logs, it seems vector would work fine for that simple purpose.

Hey all :) When using the Loki sink, I am continuously getting entry out of order errors for my logs. Does anyone have any experience?

I (think) the problem is that because we deploy vector as a daemonset in our clusters (currently at 4 pods) it's a decentralised deployment, making things tricky for loki to handle. But we thought adding a unique label to each instance would solve the problem.

I added a unique label for each instance withlabels.vector_instance = "${HOSTNAME}" but I'm still getting the same error. I can verify the label exists by inspecting the logs in grafana because some are coming through, but most are being rejected!

I've also tried:

labels.vector_instance = {{ host }}
request.in_flight_limit = 1
request.rate_limit_num = 1

Hi Team,
We are not able to pass the ACL permissions to push objects to give full control on S3 bucket for owner, also i can see "bucket-owner-full-control" this ACL is not present in your Vector page at https://vector.dev/docs/reference/sinks/aws_s3/#acl. Please let us know how to grant full permissions to bucket owner when Vector trying to push data to S3 bucket should have canonical ID. Please respond back ASAP, it is very urgent we are stuck with this almost 3-4 days, your help will be truly appreciated... :-)

In the s3 sink module, is there a way I can specify the original tail file name or parts of the file name as tokens in the s3 prefix path expression?
As of now it seems like only strftime date expressions are allowed

Hi, Is there a transform for fields that allows only specific fields to be passed from a sink. I'm looking at a way to reduce the fields from journald (especially all the SYSTEMD* fields) I could us remove_fields but I would have to specify a huge list) It would be nice to have something like pass_fields (that would only output those specific fields)

5 replies

journalctl (which I believe the sink calls) does have a --output-fields argument that could solve this as well but this seems like a more general use case

Hey there

I got to know vector a few months ago and have been using it personally for all the non-profit projects I work on.
Now I would like to bring it's awesome performance to the team I work at currently but at that scope, it's not anymore just a small thing.

Our current setup consists of logstash scaling up or down dynamically depending on the load and all the apps pushing their filebeat, packetbeat, metricbeat, etc. data (elastic stack beats) to it. As I would like to transition to vector my first attempt would be bringing over vector to replace logstash to have all the current setup elastic stack compliant but benefit from the performance of vector.

I again read through some parts of your docs and found some stuff I'm currently concerned about.

One would be the at least delivered once guarantee https://vector.dev/docs/about/guarantees/#at-least-once
You state that you should specify some kind of path to have events queued up until they can be delivered once the destination is available again. A nice feature but that means my container has to be stateful?

I thought about having vector reading from a kafka topic but that raised also some questions. I read part of the kafka source code but couldn't find a part where the instances talk to each other. Does this mean each instance would consume the event? Is vector cloud native?

I may misunderstand some scaling vector but I couldn't find a part in the docs explaining those situations.

Hi, I'd like to clarify batching in the kafka sink: It's clearly stated in the docs that it doesn't batch data and send it event by event. Does this mean that batch.num.messages/queue.buffering.max.ms/batch.size/etc librdkafka parameters don't work in Vector?

Hi All,
Hope you can help me, I'm trying to stream data from Kafka to GCS.
The requirement is to create an object for each event from Kafka and the object name is compound from content in the event.
The first question, is it possible not to use the batch option? (or batch 1)
Second, I think I saw it possible to reference all fields can I use conversion and split of date from one field?
third, If I'm reading from Kafka can I skip disk buffer and still achieve at least one?

Thank you all!

@db2jlu_twitter I'm not super familiar with Clickhouse, but there is an open issue for metrics support: timberio/vector#3435 . It may just not be implemented yet.

Looking at that though, are you sure that's the reason? It seems like it might be a mismatch in the schema or datatypes in clickhouse or, possibly, that vector is sending invalid JSON

Hello, should vector be fingerprinting inputs from the file source when they are older than the ignore_older value?

I have an application that logs to many new logs, so I have an arbitrarily low ignore value to limit the scope of what vector sees, but I am running into issues with it opening too many files.

[sources.access-raw]
  # General
  type = "file"
  ignore_older = 300
  include = ["/var/log/od/access_*.log"]
  start_at_beginning = false
  oldest_first = true
  fingerprinting.strategy = "checksum"
  fingerprinting.ignored_header_bytes = 2048
  fingerprinting.fingerprint_bytes = 4096

Aug 25 14:39:14 vm8857 vector: Aug 25 14:39:14.117 ERROR source{name=access-raw type=file}:file_server: file_source::file_server: Error reading file for fingerprinting err=Too many open files (os error 24) file="/var/log/od/access_2020-02-24_13-53-24_pid_2074.log"

I could change max_open_files, which is limited to 1024 for the vector user, but it seems odd to have to do such a thing when only one log file at a time is being written.

Jesse Szwedko

@jszwedko

I tried this out. It looks like it isn't fingerprinting it, but I do see that it maintains an open file handle even if the file is older than the cutoff. I'll open an issue to see if this is expected
