InfluxDB ERR: database not found

The specified database does not exist in the InfluxDB instance.

Understanding InfluxDB

InfluxDB is a 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 provides a SQL-like query language called InfluxQL, which allows users to interact with the database efficiently.

Identifying the Symptom: ERR: database not found

When working with InfluxDB, you might encounter the error message: ERR: database not found. This error typically occurs when attempting to perform operations on a database that InfluxDB cannot locate.

Understanding the Issue

What Causes the Error?

The error ERR: database not found indicates that the database you are trying to access does not exist in your InfluxDB instance. This could be due to a typo in the database name, or the database might not have been created yet.

Common Scenarios

  • Attempting to write data to a non-existent database.
  • Querying a database that has not been created.
  • Using an incorrect database name in your configuration or queries.

Steps to Fix the Issue

Verify the Database Name

First, ensure that the database name you are using is correct. Check for any typographical errors in the database name. You can list all existing databases using the following command:

SHOW DATABASES

This command will return a list of all databases in your InfluxDB instance. Verify that the database you intend to use is listed.

Create the Database if Necessary

If the database does not exist, you will need to create it. Use the following command to create a new database:

CREATE DATABASE your_database_name

Replace your_database_name with the desired name for your database. Once created, you can proceed with your operations.

Check Configuration Files

If you are using configuration files or environment variables to specify the database name, ensure that these are correctly set. Double-check any scripts or applications that interact with InfluxDB to confirm they are using the correct database name.
