Strange behaviour of Celery-Flower

[mmoossen]

Hi, i realized a very strange behaviour of Celery-Flower.

• I got 30.000+ files to index.
• I clean the index with:

rabbitmqctl -n rabbit@search purge_queue open_semantic_etl_tasks
opensemanticsearch-delete --empty

• i navigate to /search-apps/files/ and press "index now".
• i can see files get indexed on the search page
• i can also see the indexed files in the logs with

systemctl status opensemanticetl

• and i also see the queued files with

rabbitmqctl -n rabbit@search list_queues

but MOST of the time, the celery-flower queue stays empty.

And really MOST of the time, but not all the time. SOMETIMES celery-flower shows the process, but MOST of the time NOT. But always all files get indexed!

The same behaviour can also be observed with incremental indexing.

1. have you had any behaviour like this?
2. do you know what could be wrong?

many thanks Michael

Which flavour of opensemanticsearch do you use? Celery flower is missing at all on my installation of open-semantic-search_21.12.26 on Debian 11.

We use the last version available at that time: open-semantic-desktop-search_21.01.03.ova

And it is definitively installed:

# apt list --installed | grep celery
python3-celery/oldstable,now 4.2.1-3 all [installed,automatic]

And it is accessible from this button:
