Sologger

Sologger is a set of Rust libraries and binaries for parsing raw Solana RPC logs into structured records and transporting them over TCP to Logstash or OpenTelemetry endpoints.

Practical overview

When it fits

Use Sologger when you have Solana RPC logs and want to structure them for program-level observability or transport them to a Logstash or OpenTelemetry endpoint.

Who it is for

  • Solana developers who need structured logs for on-chain programs.
  • Operators connecting Solana RPC logs to a Logstash or OpenTelemetry observability pipeline.
  • Application developers who want libraries for extracting, structuring or exporting Solana logs.

Documented uses

  • Parse raw Solana RPC logs into structured logs for specified program IDs.
  • Extract logs from Solana API structures such as blocks, transactions and responses.
  • Forward structured logs over TCP to Logstash or OpenTelemetry.
  • Prepare a documented Compose configuration for monitoring chosen program IDs with Parseable or OpenSearch.
Before you choose

Requirements & limits

The repository specifies the Apache-2.0 license and links to a browser-based Sologger UI.

  • The Logstash and OpenTelemetry transports are enabled through separate build features.
  • The README recommends separate binaries if both Logstash and OpenTelemetry support are required.
  • Sologger's default config path is ./config/local/sologger-config.json; SOLOGGER_APP_CONFIG_LOC can override it.
  • The repository's Compose examples use program IDs in sologger-config.json to select programs for monitoring.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Build a Sologger binary for one transport

Build the binary with Logstash or OpenTelemetry transport enabled.

Before you start

  • The Sologger source repository
  • Rust Cargo
  • Choose either Logstash or OpenTelemetry as the binary's transport

Steps

  1. For Logstash transport, run the command below.

    Documented command
    cargo build --features 'enable_logstash'

  2. For OpenTelemetry transport, run the command below.

    Documented command
    cargo build --features 'enable_otel'

Expected outcome

A Sologger binary built with the selected transport feature.

Guide limitations

  • The README says enabling both features in one build is possible but not recommended; it recommends building and running separate binaries when both destinations are needed.
  • This guide covers building only; configuration and running the binary are separate steps.

Set up a Docker Compose example for program monitoring

Prepare a documented Sologger Compose example to monitor selected Solana program IDs with a log management system.

Before you start

  • The Sologger repository's Docker Compose examples
  • Program IDs for the Solana programs to monitor

Steps

  1. Choose the repository's Parseable or OpenSearch Docker Compose example.

  2. Update the program IDs in sologger-config.json for the programs to monitor.

Expected outcome

The example configuration is set to monitor the selected program IDs.

Guide limitations

  • The documented steps cover selecting the example and editing program IDs, not starting the Compose services or confirming a running pipeline.
