What is Telegraf?

What is Telegraf? Telegraf is a plugin-driven server agent for collecting and sending metrics and events from databases, systems, and IoT sensors. Telegraf is written in Go and compiles into a single binary with no external dependencies, and requires a very minimal memory footprint.

What is cardinality in InfluxDB?

series cardinality The number of unique database, measurement, tag set, and field key combinations in an InfluxDB instance. For example, assume that an InfluxDB instance has a single database and one measurement. The single measurement has two tag keys: email and status .

What is InfluxDB cloud?

InfluxDB is a time series database designed to handle high write and query loads. Telegraf. Open source server agent to collect metrics from stacks, sensors and systems. InfluxDB Enterprise. Turns any InfluxData instance into a production-ready cluster that can run anywhere.

How do I monitor InfluxDB performance?

To monitor the internal performance of InfluxDB, enable the InfluxDB input plugin in the Telegraf configuration files used to run Telegraf on InfluxDB instances. The InfluxDB input plugin pulls InfluxDB internal metrics from the local InfluxDB /debug/vars endpoint.

What is shard duration in InfluxDB?

Shard Duration The shard duration determines how much time each shard group spans. The specific interval is determined by the SHARD DURATION_ of the retention policy.

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 retention policy in InfluxDB?

A retention policy (RP) is the part of InfluxDB data structure that describes for how long InfluxDB keeps data. InfluxDB compares your local server’s timestamp to the timestamps on your data and deletes data that are older than the RP’s DURATION . A single database can have several RPs and RPs are unique per database.

How do I create a measurement in InfluxDB?

In INFLUX DB , you cant create empty measurements. You need to add some data as well. You can check Field and tag keys by executing show field keys or show tag keys . In this way, you can create measurement with specifying your required field and tag keys.

Is InfluxDB SQL?

InfluxDB is similar to a SQL database, but different in many ways. … 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.

What is tag in InfluxDB?

InfluxDB lets you specify fields and tags, both being key/value pairs where the difference is that tags are automatically indexed. Because fields are not being indexed at all, on every query where InfluxDB is asked to find a specified field, it needs to sequentially scan every value of the field column.
