There's several, depending on use case. Each make different tradeoffs, so you have to decide what's important for you.
For example Prometheus (which I work on) is great at reliable monitoring and powerful processing of metrics at high volumes, but it'd be unwise to use it for event logging or customer billing.
If you're doing IoT or event logging then InfluxDB might be a good choice for you, though if you're doing more text-based logging then Elasticsearch is nearer to what you're looking for.
