Influxdb select time

Hello NibeckjWelcome. You can create variables for those times and use the flux date package. Anaisdg : Can you please give another hint how to combine create-variable and the influxdb select time

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.

Influxdb select time

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. Either way, since this is purely an Influx and not a Grafana question, the Influx forum may be a better place to find a solution. Thanks svetb for reply. I am running query under grafana itself. So what are the ways by which I can workaround this problem. Any reason for this kind of restriction? Also one more question I had, can I create new variable say TimeCopy from Time and use this as integer for comparison with my variable? I tried this as well, but TimeCopy and Time field both can not co-exists in influx, afaik. I understand. You should certainly be able to do that, yes.

What would be my best option?

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.

Hello Nibeckj , Welcome. You can create variables for those times and use the flux date package. Anaisdg : Can you please give another hint how to combine create-variable and the date-packages? Nibeckj : Did you find a solution to your problem. For Nibeckj original use case, the query would look something like:. Thanks a lot for the quick help! Such an easy solution.

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.

Can any expert please guide me on this, it would be of great help? Support and feedback Thank you for being part of our community! See Mathematical Operators for more on supported operators. Nibeckj May 25, , pm 1. The query returns data with timestamps that occur between August 19, at and August 19, at InfluxDB Clustered is currently in limited availability and is only available to a limited group of InfluxData customers. Sample syntax for multiple subqueries:. If interested in being part of the limited access group, please contact the InfluxData Sales team. For more information, see Frequently asked questions. Integers and unsigned integers are parsed as Unix microsecond timestamps and return the corresponding RFC timestamp. The query returns data with timestamps that occur between September 17, at and days from now. Since those two fields are the only ones that exist in every serie.

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.

One raw point 6. Hi, I am using influxdb and in the select query I read time and newTs as db field represents epoch in ns as below. Any reason for this kind of restriction? The start time of the time range is specified by the TZ timestamp. The example below uses interpolate to fill null values by interpolating values between non-null values. If interested in being part of the limited access group, please contact the InfluxData Sales team. As another example, I recently wrote a bunch of points to a database with an accidental unwanted column. I am running query under grafana itself. See Database Management for how to manage databases and retention policies. Example 1: fill Example 2: fill linear Example 3: fill none Example 4: fill null Example 5: fill previous. Tuong March 1, , am I also trying to sum up data energy consumption between a time range using th hourSelection function. We had to create a dataset with less regular data to work with fill linear.
