What is InfluxDB command?

InfluxDB's command line interface ( influx ) is an interactive shell for the HTTP API. Use influx to write data (manually or from a file), query data interactively, and view query output in different formats.

How do I start InfluxDB UI?

To run InfluxDB, start the influxd daemon (InfluxDB service) using the InfluxDB command line interface. Once you've started the influxd daemon, use localhost:8086 to log in to your InfluxDB instance.

What is Cpl command?

cpl is a run command shortcut to open the Add/Remove Programs or Uninstall a Program list on Microsoft Windows XP, Vista, 7, 8, and 10. To use the appwiz. cpl command on your computer, press the Windows Key ( ) + R on your keyboard at the same time. The Run Command window should come up. In this box, type appwiz.

How do I connect to InfluxDB UI?

The InfluxDB UI is packaged with InfluxDB and runs as part of the InfluxDB server. To access the UI, start the influxd service and visit http://localhost:8086 in your web browser.

How do I use influx query?

To perform an InfluxQL query, send a GET request to the /query endpoint, set the URL parameter db as the target database, and set the URL parameter q as your query. You can also use a POST request by sending the same parameters either as URL parameters or as part of the body with application/x-www-form-urlencoded .

What is influx tool?

InfluxDB's Command Line Interface ( influx ) is an interactive shell for the HTTP API that comes with every InfluxDB package. Use influx to write data (manually or from a file), query data interactively, and view query output in different formats: Go straight to the documentation on: Launching influx.

How does InfluxDB work?

InfluxDB organizes data on disk into immutable runs of values for a single column of a series. A delete operation needs to undo a lot of that work for a subset of points. In InfluxDB, deleting a row from the database produces a tombstone. A tombstone includes a series key and the min and max time of the deleted range.

What is InfluxDB URL?

InfluxDB OSS is accessed at localhost:8086 by default, but you can also customize your InfluxDB host and port. Default host: localhost. Default port: 8086. http://localhost:8086/

Why do we use InfluxDB?

InfluxDB is purpose-built for time series data. Relational databases can handle time series data, but are not optimized for common time series workloads. InfluxDB is designed to store large volumes of time series data and quickly perform real-time analysis on that data.

How does InfluxDB work?

InfluxDB organizes data on disk into immutable runs of values for a single column of a series. A delete operation needs to undo a lot of that work for a subset of points. In InfluxDB, deleting a row from the database produces a tombstone. A tombstone includes a series key and the min and max time of the deleted range.

How to query data from InfluxDB?

To perform an InfluxQL query, send a GET request to the /query endpoint, set the URL parameter db as the target database, and set the URL parameter q as your query. You can also use a POST request by sending the same parameters either as URL parameters or as part of the body with application/x-www-form-urlencoded .

Is InfluxDB NoSQL?

InfluxDB is a NoSQL database. In many real-world projects, it typically needs to develop data collect applications to collect and send data to the process engine, and then the process engine will process the collected matrix to save in the database.

How to store data in InfluxDB?

InfluxDB stores data in shard groups. Shard groups are organized by retention policy (RP) and store data with timestamps that fall within a specific time interval called the shard duration. The shard group duration is also configurable per RP. To configure the shard group duration, see Retention Policy Management.

Why use InfluxDB instead of MySQL?

"Time-series data analysis" is the primary reason why developers consider InfluxDB over the competitors, whereas "Sql" was stated as the key factor in picking MySQL. InfluxDB and MySQL are both open source tools.

How to create a database in InfluxDB?

A fresh install of InfluxDB has no databases (apart from the system _internal ), so creating one is our first task. You can create a database with the CREATE DATABASE <db-name> InfluxQL statement, where <db-name> is the name of the database you wish to create.

How do I check logs in InfluxDB?

If InfluxDB was installed using a pre-built package, and then launched as a service, stderr is redirected to /var/log/influxdb/influxd. log , and all log data will be written to that file. You can override this location by setting the variable STDERR in the file /etc/default/influxdb .
