Logging

Since @subsquid/cli@2.0.0

Subsquid Cloud automatically collects the squid logs emitted by the processor, API server and the database pods. For more details on how to use the built-in logger in the squid processor, logging namespaces and severity flags (via environment variables SQD_DEBUG, SQD_TRACE, SQD_INFO), see the Logging page. The environment variables can be passed to the squids during the deployment to the Cloud, see Environment Variables for details.

To inspect and follow the squid logs from all the squid services, use sqd logs:

sqd logs <name>@<version> -f

There are additional flags to filter the logs:

• -f to follow the logs
• -c allows filtering by the container (can be processor, db, db-migrate and query-node)
• -l allows filtering by the severity
• -p number of lines to fetch (default: 100)
• --since cut off by the time (default: 1d). Accepts the notation of the ms library: 1d, 10h, 1m.

Example

sqd logs squid-substrate-template@v1 -f -c processor -l info --since 1d
