Configuration options

The following settings can be optionally configured:

• dsn The Cassandra server DSN (Data Source Name), for example 127.0.0.1. reference: https://pkg.go.dev/github.com/gocql/gocql
• port (default = 9042): The Cassandra server port
• timeout (default = 10s): The Cassandra server connection timeout
• keyspace (default = otel): The keyspace name.
• trace_table (default = otel_spans): The table name for traces.
• replication (default = class: SimpleStrategy, replication_factor: 1): The strategy of replication. https://cassandra.apache.org/doc/4.1/cassandra/architecture/dynamo.html#replication-strategy
• compression (default = LZ4Compressor): https://cassandra.apache.org/doc/latest/cassandra/operating/compression.html
• auth (default = username: "", password: "") Authorization for the Cassandra.

Example

exporters:
  cassandra:
    dsn: 127.0.0.1
    port: 9042
    timeout: 10s
    keyspace: "otel"
    trace_table: "otel_spans"
    replication:
      class: "SimpleStrategy"
      replication_factor: 1
    compression:
      algorithm: "ZstdCompressor"
    auth:
      username: "your-username"
      password: "your-password"
