compactor: no downsampling, why? How to enable/activate/implement downsampling? #6866

Kiara0107 · 2023-11-01T13:19:39Z

Thanos, Prometheus and Golang version used:

Thanos: v0.32.5
Prometheus: 2.47.2
GoVersion: go1.21.3
Docker version 24.0.7

Object Storage Provider: S3 - Wasabi

What happened: no downsampling, but also no error
Metric: thanos_compact_todo_downsample_blocks = 0 (flatliner)
Bucket_store_block_series tag block.resolution = 0 (always..)

What you expected to happen: since there is data for the last 10 months I would expect downsampled blocks.

How to reproduce it (as minimally and precisely as possible):
Prometheus docker run:

docker run -d -p 9090:9090 \
      -v /etc/prometheus:/prometheus/ \
      -u root \
      --restart unless-stopped \
      --network prometheusnet \
      --name prometheus prom/prometheus:latest \
      --config.file=/prometheus/prometheus.yml \
      --storage.tsdb.path=/prometheus \
      --storage.tsdb.min-block-duration=2h \
      --storage.tsdb.max-block-duration=2h \
      --storage.tsdb.retention.time=3d \
      --web.enable-lifecycle \
      --web.enable-admin-api

Thanos compact:

docker run -d -p 19191:19191 \
      -v /etc/thanos-store/storage-bucket.yml:/storage.yml \
      -v /etc/thanos-store/tracing-config-compact.yml:/tracing-config.yml \
      -u root  \
      --restart unless-stopped \
      --network prometheusnet \
      --name thanos-compact thanosio/thanos:v0.32.5 compact \
      --data-dir /var/thanos/compact \
      --objstore.config-file storage.yml \
      --http-address 0.0.0.0:19191 \
      --wait \
      --retention.resolution-raw=30d  \
      --retention.resolution-5m=90d \
      --retention.resolution-1h=730d \
      --tracing.config-file=/tracing-config.yml

Full logs to relevant components:
N/A there are no errors.. or mentions..

Anything else we need to know:
I've read the docs on https://thanos.io/tip/components/compact.md/#downsampling, https://thanos.io/tip/operating/compactor-backlog.md/ and https://thanos.io/tip/components/sidecar.md/
But still I'm clueless on how to enable downsampling.

Can you post a screenshot of the block UI from the compactor? You can access it on the http port which you've set to be 19191

Kiara0107 · 2023-11-02T10:39:42Z

Yes of course. This is what you expected?

fpetkovski · 2023-11-02T11:16:34Z

So downsampling happens only for blocks that are 2 days or 14 days in duration. Your bucket seems to have many 2 hour blocks, which is probably because no compaction is taking place. Do you see any logs related to compaction?

To-do compactions is doing something but stays very high, maybe it's busy? (I thought at least.. so I increased the concurrency from 1 to 6.. but don't see much happening..

fpetkovski · 2023-11-02T12:01:33Z

I am not sure if any compaciton is taking place. I think that pending values go down due to retention, and not because compactions are completed.

Kiara0107 · 2023-11-02T12:48:14Z

Any idea on how to check?

PabloPie · 2023-11-02T13:57:58Z

We seem to be having a similar issue since we upgraded to v0.32.X from v0.31. No error logs at all but we can see that the metric thanos_compact_group_compactions_total has been 0 since the upgrade, while thanos_compact_todo_compactions keeps increasing.

yeya24 · 2023-11-02T16:38:18Z

~~We have a guide on how to troubleshoot this problem https://thanos.io/tip/operating/compactor-backlog.md/#troubleshoot-compactor-backlog~~

Updated: nvm you already mentioned you read the doc. Downsampling is enabled by default. You can scale up compactors to catch up.

@Kiara0107 Can you check thanos_compact_todo_compactions metrics first? This metric need to be 0. Downsampling only happens after all compactions finish

One possibility of you have thanos_compact_todo_downsample_blocks to 0 is because your compaction is slow and your compacted blocks are not large enough to be able to downsample.

Kiara0107 · 2023-11-03T09:37:28Z

Yes it looks like there is no compaction done. I increased the concurrency now to 20 and see the MEM of the container increasing a lot. But other then that, no changes.

fpetkovski · 2023-11-03T09:55:54Z

Could you post a graph of bucket operations?

Also, this could be an bug introduced in 0.32 as noted in another issue. Could you try 0.31 to see if it makes a difference?

Kiara0107 · 2023-11-03T10:03:28Z

Will revert to 0.31

Kiara0107 · 2023-11-03T10:14:18Z

I think something is corrupted now, I face the "critical error detected; halting" message in the log (way to long to completely paste here)

Similar log for me actually:
populate block: chunk iter: cannot populate chunk 8 from block 01HA60TQ55Z0DRWHW5ZAD51AYB: segment index 0 out of range","level":"error","msg":"critical error detected; halting"

I guess a problem with a single block is halting all compaction?

Mine is slighty different, starts with:

Any suggestions on how to fix this 'overlap' error? Manually removing buckets from S3 doesn't feel like te way to go :S

PabloPie · 2023-11-03T11:47:29Z

It seems my compactor is now making progress. Apparently, the compactor had been running for weeks doing nothing after it encountered an error with a block (Our thanos compactor dashboard wasn't showing the most critical metric: thanos_compact_halted). I also enabled the flag suggested here, which only made the error worse, because it only skipped logging the error, not the block.

The only solution I could think of is manually marking the failing blocks for non-compaction with thanos tools bucket mark --id=01HA0N5HY0AWK2K75E7Z121JC8 --marker=no-compact-mark.json. Not sure if that can help you @Kiara0107.

fpetkovski · 2023-11-03T11:51:13Z

@Kiara0107 do you have replicated blocks, e.g. coming from prometheus pairs?

Kiara0107 · 2023-11-03T12:12:52Z

@fpetkovski yes I have. We have one Prometheus pair running

global:
  scrape_interval: 30s
  external_labels:
    prometheus: 'COLO06'
    prometheus_replica: 'observer1'

and

global:
  scrape_interval: 30s
  external_labels:
    prometheus: 'COLO06'
    prometheus_replica: 'observer2'

fpetkovski · 2023-11-03T12:27:23Z

In this case you should use prometheus_replica as the replica label on the compactor and enable vertical compaction.

Kiara0107 · 2023-11-03T12:53:18Z

My hero. Looks like that indeed is helping, Thanos-compact logs shows:

Which is for sure different then before. I will leave it to it now and see if compaction continues and downsampling will be activated.
Thnx for now :)

FYI I've added these 2 flags to the docker run command:
--deduplication.func=""
--deduplication.replica-label="prometheus_replica" \

yeya24 · 2023-11-19T08:25:12Z

Since it is a configuration issue, I will close this one.

We should update compactor backlog troubleshooting doc to mention checking compactor halt first.

#6906

jakuboskera · 2024-04-02T08:55:41Z

In this case you should use prometheus_replica as the replica label on the compactor and enable vertical compaction.

So everytime when I have two or more replicas of prometheus scraping same targets (same cluster) distinguished by label prometheus_replica which has different value, I should add these two params to compactor?

- --deduplication.func=
- --deduplication.replica-label=prometheus_replica

Or what is the best and recommended way how to setup compactor when I have HA prometheus in the same cluster?

Thanks
