VictoriaMetrics Data ingestion rejected

What is VictoriaMetrics Data ingestion rejected

Understanding VictoriaMetrics

VictoriaMetrics is a high-performance, cost-effective, and scalable time-series database designed for large-scale monitoring and observability. It is optimized for fast data ingestion and querying, making it a popular choice for handling metrics and time-series data.

Identifying the Symptom: Data Ingestion Rejected

When using VictoriaMetrics, you might encounter an issue where data ingestion is rejected. This can manifest as error messages in logs or a noticeable lack of new data appearing in your database.

Common Error Messages

Error: "Data ingestion rejected due to incorrect format." Error: "Network issues detected, data ingestion failed." Error: "Rate limit exceeded, data ingestion rejected."

Exploring the Issue

Data ingestion rejections in VictoriaMetrics can be caused by several factors:

Incorrect Data Formats

VictoriaMetrics expects data to be in a specific format. If the data format is incorrect, the ingestion process will fail. Ensure that your data adheres to the expected format as outlined in the VictoriaMetrics documentation.

Network Issues

Network instability can disrupt the data ingestion process. This can be due to connectivity issues, high latency, or packet loss.

Exceeded Rate Limits

VictoriaMetrics may reject data if the rate of incoming data exceeds the configured limits. This is a protective measure to prevent overloading the system.

Steps to Fix the Issue

Verify Data Formats

Ensure that the data being sent to VictoriaMetrics is in the correct format. Refer to the official documentation for the expected data format. Use tools like curl or wget to test data ingestion manually:

curl -X POST http:///api/v1/import -d 'your_data_here'

Ensure Network Stability

Check your network connection for any issues. Use tools like ping or traceroute to diagnose network problems. Ensure that your network configuration allows stable and consistent connections to the VictoriaMetrics server.

Adjust Ingestion Rate Limits

If you suspect that rate limits are causing the issue, consider adjusting the rate limits in your VictoriaMetrics configuration. This can be done by modifying the -maxConcurrentInserts parameter:

victoria-metrics -maxConcurrentInserts=1000

Refer to the command-line flags documentation for more details on configuration options.

Conclusion

By understanding the potential causes of data ingestion rejections in VictoriaMetrics and following the outlined steps, you can effectively diagnose and resolve these issues. For further assistance, consider reaching out to the VictoriaMetrics community or consulting the official documentation.
