Evaluating Performance and Correctness (2019)
TL;DR
VictoriaMetrics offers impressive data compression, reportedly 3-4x better than Thanos, but initial tests show Prometheus has slightly better compression and more comprehensive data storage.
✦ Why It Matters
Evaluate your data storage solutions by comparing compression rates and data completeness today.
Key Takeaways
- Prioritize data integrity when selecting monitoring tools.
- Conduct thorough testing of query performance and correctness.
- Be cautious of trade-offs between compression and data precision.
- Consider the implications of using independent implementations of query languages.
How It Works
The comparison involved setting up both Prometheus and VictoriaMetrics to ingest the same data, focusing on compression and query performance. Snapshots were taken to measure disk usage, and various queries were executed to assess data accuracy and response times.
⚠ The Catch
VictoriaMetrics exhibited significant issues with timestamp handling, returning incorrect results for recent queries and failing to manage NaNs properly, which could mislead users.
