Im Durchschnitt wird dieses Tutorial Install and Set Up InfluxDB on Ubuntu 16. timeserie,tag=value,tag=value, measure=value,measure=value timestamp Les datapoints sont indexés sur le timestamp (primaire) et sur les tags (secondaires) Premiers Pas Via le shell influx influx -host localhost Créer la base CREATE DATABASE mydb SHOW DATABASES USE mydb Insérer des points. The term is from a Greek word for "form" or "figure. 9 , Sensor=Room2. For some time we have been collecting metrics using Statsd, feeding them into Graphite and alerting on them via Nagios. Your Influx datasource is now set and ready to be queried. Influxdb is a time series database to make historical analysis, predictive analysis and anomaly detection. An example of how this emitter parses a Druid metric event into InfluxDB's line protocol is given here: The syntax of the line protocol is : [,=[,=]] =[,=] [] where timestamp is in nanoseconds since epoch. Open Monokot Server Administrator and connect to the local server. In addition, InfluxQL functions do not accept a tag value as a primary argument. The tag values are indexed. 在 InfluxDB 中 series 是一组数据的集合,这些数据共享一个 retention policy,measurement 和 tag set。理解 series 的概念才能设计好数据库的 schema。 最后 point 是在相同 series 中相同 timestamp 的数据。 InfluxDB Shell.

Check Name: Name for the check to be run, it is display in console for better understanding of performed check. host=lcg1423. Both tag keys and tag values are strings. You could find some performance tests for InfluxDB and Graphite here. fillNullValues("0"); It will replace all null values with 0. For example, in sample flow at node-red-contrib-influxdb three field values (numValue, randomValue, strValue) and two tags (sensor1 and device2) are written to the test measurement. SELECT MEAN(field_key) FROM measurement SELECT MEAN(field_key) FROM measurement WHERE time > now() - 1d GROUP BY time(10m) SELECT MEAN(field_key) FROM measurement WHERE time > 1434059627s GROUP BY tag_key Median. How to use libcurl. For example, to search all rows where temperature was greater than 90 degrees (e. 1 This will result in two rows being returned for our example data: To give a little more detail, data in InfluxDB is organized by time series, which is test_metric in our example.

Having rich tag sets allows you to combine data from different sources, which can be very useful or totally meaningless if the data are not related. I know I can get field values via the SHOW TAG VALUES function, but it prepends the key name, and I don't want the key name (would be nice if I could "SELECT 'value' FROM SHOW TAG VALUES). We can also collect and store data center temperature data in InfluxDB. 4, a mytag1 value of 12, and a mytag2 value of 14. Time-series databases, however, typically expect data in a simple format: metric name, metric value, timestamp and, optionally, some tags or keys. points使用Line协议写入influxDB,格式如下:.

InfluxDB is a time series database written entirely in Go. As the data grows in the InfluxDB , we might need to delete old data which is irrelevant. Both tags and fields can store values of certain types. Query performance scales with the number of series, so in our. You typically make a field as a tag because you need to use it as a condition in the where clause to improve query performance. Since these are integers, they appear not to work with the matching regexes at all, so something like where !~ /. writePoints sends a list of points together in a batch to InfluxDB. You can even use InfluxDB outside IT related usage for example you want to store time series market price of a. If you do not pass it, InfluxDB::LineProtocol will use Time::HiRes to get the current timestamp. In computers, a CSV (comma-separated values) file contains the values in a table as a series of ASCII text lines organized so that each column value is separated by a comma from the next column's value and each row starts a new line.
