Celery Integration

Kanchi monitors your Celery tasks by connecting to your broker and result backend. Most Celery configurations work out of the box, but some settings can improve your monitoring experience.

Task argument size limits

Celery truncates task arguments and keyword arguments at 1024 characters by default when storing task representations. If you're working with large payloads — like passing JSON blobs or file contents as task arguments — you'll see ... in Kanchi's task detail view instead of the full data.

This is a Celery limitation, not a Kanchi one. The good news: it's configurable.

Increasing the limits

Override Celery's defaults on your app instance:

from celery import Celery

app = Celery('your_app')

# Increase representation limits (default: 1024)
app.amqp.argsrepr_maxsize = 10000
app.amqp.kwargsrepr_maxsize = 10000

Performance consideration: Larger limits mean more data stored in your broker and database. If you're passing multi-megabyte arguments, consider storing them elsewhere (S3, Redis, etc.) and passing references instead.

When to adjust these values:

Task detail pages show truncated arguments (...)
You need full argument inspection for debugging
Your tasks legitimately require large payloads

Reference: See Celery's argsrepr_maxsize documentation for more details.
