InfluxDB is a powerful time-series database designed to handle high write and query loads. It is optimized for time-stamped data, making it ideal for use cases such as monitoring, IoT, and real-time analytics. InfluxDB supports a SQL-like query language called InfluxQL, which allows users to interact with and analyze their time-series data efficiently.
When working with InfluxDB, you might encounter the error message: ERR: invalid precision. This error typically surfaces when you attempt to write data points with a time precision that InfluxDB does not recognize or support.
Upon executing a write operation, you receive an error message indicating an invalid precision. This prevents the data from being successfully written to the database, potentially disrupting data collection and analysis workflows.
The ERR: invalid precision error occurs when the specified time precision in your write request is not among the supported options. InfluxDB requires a valid time precision to accurately store and retrieve time-series data. Supported precisions include:
ns - Nanosecondsu - Microsecondsms - Millisecondss - Secondsm - Minutesh - HoursThis error is often caused by a typo in the precision value or using a precision format that is not supported by InfluxDB. It is crucial to ensure that the precision specified aligns with one of the supported formats.
To fix the ERR: invalid precision error, follow these steps:
Check the precision specified in your write request. Ensure that it matches one of the supported formats: ns, u, ms, s, m, or h. For example, if you are writing data with timestamps in milliseconds, use ms as the precision.
If the precision is incorrect, modify your write request to use a valid precision. Here is an example of a correct write request using curl:
curl -i -XPOST 'http://localhost:8086/write?db=mydb&precision=ms' --data-binary 'weather,location=us-midwest temperature=82 1465839830100400200'
After making the necessary changes, execute the write operation again to ensure that the error is resolved. If the data is successfully written, the issue is fixed.
