Begin ingesting cache spans

[DominikB2014]

Ingest general cache spans (i.e spans with op of cache.*)

Create metrics for db.redis spans with tags

• Environment
• Span op (cache.get_item, cache.save, etc)
• Transaction name
• Duration
• Cache hit or miss

The following tags will need to be added as well, but do not have data collect this data in the SDK yet.

• Domain/table ( or some identifier to which cache it is, db vs nodestore cache in your example)

const Prometheus = require('prom-client');

// Definir el histograma para la duración de las operaciones de caché
const cacheOperationDuration = new Prometheus.Histogram({
name: 'cache_operation_duration_seconds',
help: 'Duration of cache operations',
labelNames: ['transaction_name', 'action', 'environment', 'cache_result', 'domain_table'],
buckets: [0.1, 0.5, 1, 2, 5] // Definir los intervalos de duración
});

// Función para registrar una operación de caché
function recordCacheOperation(transactionName, action, environment, cacheResult, domainTable, duration) {
cacheOperationDuration.labels(transactionName, action, environment, cacheResult, domainTable).observe(duration);
}

// Ejemplo de registro de una operación de caché
recordCacheOperation('example_transaction', 'get', 'production', 'hit', 'user_data', 0.05);
