Influxdb select time

To use with InfluxDB, influxdb select time, cast the return value to a timestamp. The following example uses the sample data set provided in Get influxdb select time with InfluxDB tutorial. To use with InfluxDB, cast the return value to a string. The following example uses the sample data set provided in the Get started with InfluxDB tutorial.

I am using influxdb and in the select query I read time and newTs as db field represents epoch in ns as below. So how can I use variable in the where clause, I have added newTs as integer variable in the database, even I tried newTs::integer in the select query but it fails. How to solve this problem? Can any expert please guide me on this, it would be of great help? I searched a lot on Google and Influx Documentation but failed to find this precise information. There may be a workaround, but I suspect your best bet would be trying to run the query in Flux instead.

This Product. Time Series Database:Time Syntax. By default, the start time of the time range is specified by the The end time of the time range is the time that is returned by the now function. If you do not specify this element, the default value. If you do not specify this element, the default value You can add a character to the end of an epoch timestamp to indicate a non-nanosecond time granularity. All timestamp formats support the basic arithmetic operations. The query returns the data whose timestamps occur from If the nanosecond time granularity is not specified for the start timestamp, the.

Example 1: fill Example 2: fill linear Example 3: fill none Example 4: fill null Example 5: fill previous, influxdb select time. The query returns two series of results: one for each tag value of the location tag. The first date-time string does not include a time; InfluxDB assumes the time is

This page documents an earlier version of InfluxDB. InfluxDB v2 is the latest stable version. See the equivalent InfluxDB v2 documentation: Query fields and tags. See the Sample Data page to download the data and follow along with the example queries in the sections below. Use this syntax to differentiate between field keys and tag keys that have the same name. Other supported features: Arithmetic operations , Functions , Basic cast operations , Regular expressions. For more information, see error about mixing aggregate and non-aggregate queries.

InfluxQL is designed for working with time series data and includes features specifically for working with time. You can review the following ways to work with time and timestamps in your InfluxQL queries:. If you are using the InfluxQL shell , use the precision helper command precision rfc to view results in human readable format. Specify alternative formats with the epoch query string parameter. Other supported features include: Absolute time Relative time.

Influxdb select time

A time series database TSDB is specifically made for data that can be evaluated as a "time-series," which includes sensor outputs, market trends, CPU utilization, and application performance metrics. Most popular types of databases both SQL and NoSQL are not optimized for handling large-scale scans, or summarization or aggregation of time-series data. Time-series databases have built-in functionality to work with aggregation, down-sampling, data lifecycle management and summarization. InfluxDB uses the line protocol for sending and storing data. The line protocol is the text-based format that uses the syntax below to write points to InfluxDB. The above syntax is used to insert a single point to an InfluxDB database.

Doc umentation. See the Frequently Asked Questions document for more information. That's why I mention doing it on a boolean or low numbered int column. Note that the whitespace between the - and 6m is required. How to find out? You signed out in another tab or window. Use this syntax to differentiate between field keys and tag keys that have the same name. The query returns data with timestamps between August 18, at I created variable with date as string and compared with influxdb field of date. Otherwise, if it's something you'll want to pull up frequently and it's a series with many events, you'll want to issue it as a continuous query that gets fed into another series once we add support for those. I think I have the exact same problem as feliksik In Grafana, I want to compare the now value to the most recent value from a sensor to see if the values are stale or current. We are continuing to support Flux for users in 1. Note that fill linear fills the results for the TZ time interval and the TZ time interval using the values from the TZ time interval and the TZ time interval.

Returns the current system time UTC. Windows use preset round-number boundaries based on the specified interval that are independent of time conditions in the WHERE clause. Downsample data into time-based intervals.

The subquery supports all clauses listed in this document. Downsampling is a common use case for the INTO clause. Flux is going into maintenance mode. The first query returns an error because the string field value includes white spaces. In InfluxDB, queries merge series automatically. Maarten September 22, , pm Specify a time range with epoch timestamps. For Nibeckj original use case, the query would look something like:. I have a sync task that periodically puts data in InfluxDB, where I manually set the time field of each entry. Relative time range : Define query time bounds with a duration literal added to or subtracted from timestamp literals.
