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.
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.
Data ingestion rejections in VictoriaMetrics can be caused by several factors:
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 instability can disrupt the data ingestion process. This can be due to connectivity issues, high latency, or packet loss.
VictoriaMetrics may reject data if the rate of incoming data exceeds the configured limits. This is a protective measure to prevent overloading the system.
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'
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.
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.
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.
