QUESTION
I am using Apache Zeppelin (0.9.0) and Scala (2.11.12). I want to pull some data out of a dataframe and store it to InfluxDB, later to be visualized in Grafana, and cannot figure it out. I'm trying a naive approach with a foreach
loop. The idea is to iterate through all rows, extract the columns I need, create a Point object (from this InfluxDB client library), and either send it to InfluxDB or add it to a list and then send all the points in bulk, after the loop.
The dataframe looks like this:

I'm trying to query data from InfluxDBv2 (2.0.2) using python3. The query is in flux, it works well inside InfluxDB (it displays the data well). I've tried to executed inside the same VM (Ubuntu 18.04) and the host machine (Windows10 Jupyter python-kernel=python3).

QUESTION
I have a Node.js application that I am trying to get to query InfluxDB's cloud offering, I have set it up so I can write data fine now I need the query part. My data contains a few values - or will anyways - I have an elapsed time, service, and serviceID.
Here is my query when I output it before running it

QUESTION
I have a Lambda function that is designed to take a message from a SQS queue and then input a value called perf_value
which is just an integer. The CloudWatch logs show it firing each time and logging Done
as seen in the .then()
block of my write point. With it firing each time I am still only seeing a single data point in InfluxDB Cloud. I can't figure out why it is only inputting a single value then nothing after that. I don't see a backlog in SQS and no error messages in CloudWatch either. I'm guessing it is a code issue or InfluxDB Cloud setup though I used defaults which you would expect to actually work for multiple data points

QUESTION
I am working on a project where I have an InfluxDB bucket that has a measurement of elapsedtime
and a tag of service
. I want to query Influx to be able to get all datapoints in the last 1 hour for foobar
as the service. Ideally I will add a time measurement later on which I could use to base my 1 hour off since the system that gets the elapsed time and the system that writes it to Influx are different and have about 1-2 minutes of latency between them.
I have taken some example code from here and I have gotten this which is nearly identical since I am unsure of what needs to change and could not understand the documentation (head's cloudy?).
The end goal of this is to be able to have a graph that shows the elapsedtime
for a service when I query my application - which queries Influx. I would like to be able to query based off a preset list of service and times but that is application side of things and I am giving here as context to what I'd like this to result in eventually.
ANSWER
Answered 2020-Sep-22 at 00:12The issue ended up being that the code I had copied was TypeScript which as you can imagine doesn't work in a JavaScript file. Silly mistake on my end
QUESTION
I'm running influxdb and grafana on Docker with Windows 10.
Every time I shut down Docker, I lose my database.
Here's what I know:
- I have tried adjusting the retention policies, with no effect on the outcome
- I can shut down and restart the containers (docker-compose down) and the database is still there. Only when I shut down Docker for Windows do I lose the database.
- I don't see any new folders on the mapped directory when I create a new database (/data/influxdb/data/)'. Only the '_internal' folder persists, which I assume corresponds to the persisting database called '_internal'
Here's my yml file. Any help greatly appreciated.
...ANSWER
Answered 2018-Jan-19 at 22:28I think problem is related to mounted volume not docker or influxdb. You should first find where influxdb stores data(by default it is in your home folder "~user/. influxdb" in windows) and then generate influxdb.conf file, finally mount the volumes.
QUESTION
Currently I'm trying to connect to a InfluxDB hosted on Platform.sh without any luck.
I followed the setup instruction described on https://docs.platform.sh/configuration/services/influxdb.html. After these steps the service was available on Platform.sh.
After that I used Platform.sh's community guide (https://community.platform.sh/t/how-to-access-influxdb-credentials-on-platform-sh/148) to connect to the database.
I then ran the following command and selected the application (Grafana) that is connected to the InfluxDB-service

Answered 2020-Mar-19 at 06:46As I learned on the Platform.sh forums I had to create an admin user. After the tunnel was open I had to run:

I have a problem related to importing dependencies in Scala build.sbt. I add something like this:
...ANSWER
Answered 2020-Jan-23 at 20:57Scala 2.9? I am not sure such a version ever existed. Usually Scala version numbers are using three components.
Looking at https://mvnrepository.com/artifact/com.paulgoldbaum/scala-influxdb-client this library exists for 2.10.x, 2.11.x or 2.12.x.
Use 2.12.10 for the scalaVersion
.
QUESTION
I want to send data to an InfluxDB using Apache Camel. I am at such a beginner's level, that I cannot even understand camel's documentation. I am struggling what exactly needs to be written in the tag of the spring configuration XML. In the documentation it says:
- URI format:
influxdb://beanName?[options]
- The InfluxDB endpoint is configured using URI syntax:
influxdb:connectionBean
How do I use this information? Could you provide me a more instructive example of how the config.xml looks like and how this is called in code?
Thanks
...ANSWER
Answered 2019-Oct-08 at 12:05I think you need to configure a spring boot InfluxDb class instance and then reference it as stated in the documentation using beanName.
This can be created using spring boot auto configuration:
- https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-nosql.html#boot-features-connecting-to-influxdb
- https://docs.spring.io/spring-boot/docs/current/api/org/springframework/boot/autoconfigure/influx/InfluxDbAutoConfiguration.html
According to Spring AnnotationNameGenerator the name of the default (from the yml auto configured bean) should simply be influxDB
. We can also look at the bean definition code and confirm it is creating an InfluxDB
class instance.
So then configure influxdb://influxDB
in camel.
Besides auto configuring this alternative should work too (untested - source):
QUESTION
Headers are included but static library (influxdb) is not.
My tasks.json file:
...ANSWER
Answered 2019-Oct-07 at 22:02Add an an additional reference to -lInfluxDB
should be the end of the command line. I don't know how to do this in tasks.json.
I believe the GNU linker only forward resolves dependencies. That is if library A depends on B, then -lA
must appear before -lB
in the command line order. If both A and B dependon each other, you can do -lA -lB -lA
or read this.
