What is the default cache max memory size InfluxDB?

By default, cache-max-memory-size is set to 512mb. This value is fine for most workloads, but is too small for larger write volumes or for datasets with higher series cardinality.

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 much RAM does InfluxDB need?

Regardless of the cluster load, we recommend the following guidelines for the meta nodes: vCPU or CPU: 1-2 cores. RAM: 512 MB - 1 GB. IOPS: 50.

Is large cache size good?

Cache size is important to your application because if it is set to too small of a value, your application's performance will suffer from too much disk I/O. On the other hand, if your cache is too large, then your application will use more memory than it actually needs.

Does increasing cache size affect performance?

Cache memory is a large determinant of system performance. The larger the cache, the more instructions can be queued and carried out. Storing instructions in cache reduces the amount of time it takes to access that instruction and pass it to a CPU core.

Is InfluxDB a SQL database?

InfluxDB is similar to a SQL database, but different in many ways. InfluxDB is purpose-built for time series data. Relational databases can handle time series data, but are not optimized for common time series workloads.

Can I use InfluxDB for free?

InfluxDB Cloud is the most powerful time series database as a service — free to start, easy to use, fast, serverless, elastic scalability.

Does InfluxDB use SQL?

SQL capabilities in InfluxDB

Starting with the IOx-powered version of InfluxDB, the platform supports native SQL queries. Specifically, InfluxDB supports the PostgresQL wire protocol dialect of SQL. At present, you can run SQL queries directly in the Cloud UI on IOx-enabled buckets by wrapping those queries in Flux.

What is the default user for influx?

username (Required) The username the provider will create at first - Default: administrator - Can be set with INFLUXDB_V2_USERNAME environment variable. password (Required) The password created for the username - Default: Administrator1.

How do I enable login for InfluxDB?

Locate the [http] section of your InfluxDB configuration file and set the access-log-path option to specify the path where HTTP log entries should be written. Notes: If influxd is unable to access the specified path, it will log an error and fall back to writing the request log to stderr .

How do I check my InfluxDB configuration?

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 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.

How to use InfluxDB command line?

Write data to InfluxDB with insert

Use insert into <retention policy> <line protocol> to write data to a specific retention policy. Write data to a single field in the measurement treasures with the tag captain_id = pirate_king . influx automatically writes the point to the database's DEFAULT retention policy.

Where is InfluxDB installed on Linux?

The configuration file is located at /usr/local/etc/influxd. conf with examples in /usr/local/etc/influxd.

Is there any GUI for InfluxDB?

The built-in web administration GUI is a simple way to interact with InfluxDB. For any significant use, whether writing or querying data, the HTTP API (reading, writing) or the command line interface are better options.

What is the default URL for InfluxDB?

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

Is there a UI for InfluxDB?

The InfluxDB user interface (UI) provides tools for building custom dashboards to visualize your data.

How do I check my InfluxDB configuration?

The InfluxDB system has internal defaults for all of the settings in the configuration file. To view the default configuration settings, use the influxd config command. The local InfluxDB configuration file is located here: Linux: /etc/influxdb/influxdb.

How much RAM does InfluxDB need?

Regardless of the cluster load, we recommend the following guidelines for the meta nodes: vCPU or CPU: 1-2 cores. RAM: 512 MB - 1 GB. IOPS: 50.

How do I open InfluxDB in my browser?

Accessing the UI

Once enabled, the Admin UI is available by default at port 8083 , i.e. http://localhost:8083. You can control the port in the InfluxDB config file using the port option in the [admin] section. You can also access remote InfluxDB instances, although you may only connect to one instance at a time.
