Monitoring

Each deployed squid version exposes Prometheus metrics for external monitoring with e.g. Grafana.

Processor metrics

The processor metrics are available at https://squid.subsquid.io/${name}/v/v${version}/processors/${processor}/metrics. It is also exposed for the production alias at https://squid.subsquid.io/${name}/processors/${processor}/metrics.

${processor} here is the processor name; it defaults to processor unless specified.

The metrics are documented inline. They include some values reflecting the squid health:

  • sqd_processor_last_block. The last processed block.
  • sqd_processor_chain_height. Current chain height as reported by the archive.
  • sqd_processor_archive_http_errors_in_row. The number of consecutive failed Archive requests
