Telegraf doesn’t seem to send data to influxedb in dockerised images

Asked 2022-Mar-26 at 18:35

I have a dockerised telegraf (influxdata-docker/telegraf/1.21 at master · influxdata/influxdata-docker · GitHub) and influxdb (influxdata-docker/Dockerfile at master · influxdata/influxdata-docker · GitHub).

I’m trying to send data to influxdb from ttn but without any success. The config file for telegraf is:

Just in case somebody else has the same issue, it was finally due to the fact I was using ttn v3, ie. in telegraf.conf:

topics = [ "v3/+/devices/+/up" ]

instead of:

topics = [ "+/devices/+/up" ]

QUESTION

How can I use data from more than one measurement in a single Grafana panel?

Asked 2022-Mar-21 at 13:21

I am attempting to create a gauge panel in Grafana (Version 6.6.2 - presume that upgrading is a last resort, but possible if necessary, for the purposes of this problem) that can represent the percentage of total available memory used by the Java Virtual Machine running a process of mine. the problem that I am running into is the following:

I have used Springboot actuator's metrics and imported them into an Influx database with Micrometer, but in the process, it has stored the two values that I would like to use in my calculation into two different measurements. jvm_memory_used and jvm_memory_max

My initial Idea was to simply call a SELECT on both of the measurements to get the value that I want, and then divide the "used" / "max" and multiply that value by 100 to get the percentage to display. Unfortunately I run into syntax errors when I try to do this manually, and I am unsure if I can do this using Grafana's query builder.

I know that the syntax is incorrect, but I am not familiar enough with InfluxQL to know how to properly structure this query. Here is what I had tried:

I am not particulary experienced with Influx, but since your question is how to use/combine two measurements (query results) for a Grafana panel, I can tell you about one approach:

You can use a transformation. By that, you can keep two separate queries. With the transformation mode binary operation you can simply divide one of your values by the other one.

In your specific case, to display the result as percentage, you can then use Percent (0.0-1.0) as unit and you should have accomplished your goal.

How to obtain time interval value reports from InfluxDB

Asked 2022-Mar-14 at 12:14

Using InfluxDB: Is there any way to build a time-bucketed report of a field value representing a state that persists over time? Ideally in InfluxQL query language

More specifically as an example: Say a measurement contains points that report changes in the light bulb state (On / Off). They could be 0s and 1s as in the example below, or any other value. For example:

Assuming that msg.paylaod looks something like 2020-11-18T00:00:00.000Z then you have not quoted the time string you are inserting into the query.

It should look like this:

You can follow below steps:

Execute below command to check if you can access the auth list and see all tokens list and if you have read-write permissions :
influx.exe auth list
You can also view in dasboard:
If you are not able to see token, then you can generate a token with read/write or all access.

3. It might have also happened that the retention period that you choose must have been over due to which no measurement data is available. 4. You can create a new bucket and add token that you created in above step:

InfluxDB - ERR_EMPTY_RESPONSE - Used to come up in browser, now doesn't

Asked 2021-May-30 at 10:29

Running influxdb from a Docker container.

The YML includes Telegraf and Grafana, too.

I should point out that Grafana also is not loading in my browser.

When I run netstat -n -q, and I look for "8086", I find these entries:

0.0.0.0:8086
[::]:8086
[::1]:8086

But I don't see 127.0.0.1:8086 as I would expect.

InfluxDB - 2.0 - stand alone DB

Asked 2020-Oct-28 at 17:29

I am using Influxdb with Grafana for a while and I like it. I am confused with the new version of Influxdb2.0. I was searching the doc and could not find useful info.

I have some questions.

Will Influxdb be available only as bundled with db + ui as 1 single binary going forward? Can we have standalone DB?
Will the Flux replace the current SQL like InfluxQL ? Or InfluxQL will also be supported.

...

ANSWER

Answered 2020-Oct-28 at 17:29

Yes, I believe the intention is to bundle the UI into the single binary so that it is always available with no additional installs. You can continue to use Grafana though - ignoring the bundled UI entirely*. There's no problem to ignore it so the DB is still "standalone". Since it is OSS, you could build a binary without the bundled UI if that is important for your use case.
InfluxDB 2.0 OSS is currently in RC0 (as of late Oct 2020). This version supports both InfluxQL via a compatibility API (/query) and Flux via the new /api/v2/query API querying. The query and response formats are different. The docs have examples. In general, Flux is the direction InfluxDB is going.

*There may be some rough edges in the RC around configuring the first user without using the UI and only using the API. I have not tried this. I would expect the API to continue to improve is this area.

Your specified flux query would work if itemType was a tag, however, since it is a field one of the ways to make the query work is by setting conditions on the field name and its value as follows:
