Influx DB

[jjang@gtd.eu]

Hi,

I have some questions regarding to Influx DB.

- Which version of InfluxDB open source supports Winccoa 3.17?
- Which version of InfluxDB enterprise edition supports Winccoa 3.17?

- Which version of InfluxDB open will support Winccoa 3.18?
- Which version of InfluxDB enterprise edition will support Winccoa 3.18?


Thank you so much!

Regards,

Junho

Hi Junho,

I checked in 3.17 and it is packed with influx 1.7.4.

However, on my laptop I am using latest version from InfluxDB website without issues (1.7.10).
C++
I think that it doesnt really matters as far as it is 1.x (open source or enterprise) as I guess ETM used standard c++ client which is C++ client library for InfluxDB 1.x/2.x

(see https://github.com/awegrzyn/influxdb-cxx )

Should thus even work with 2.0 then (I am curious and may install beta to try it out )

Best regards

As "adeneau" has already written WinCC OA uses the open source version 1.7.4.
Which Influx DB version an upcoming version of WinCC OA will use is not defined right now.

Why is this information needed?
Have you planned to use your own installation of InfluxDB?

The normal use case is that the customer uses the InfluxDB as it is delivered and installed with WinCC OA.

We would like to use the high availability feature but apparently the open source version of InfluxDB doesn't provides it.

How could we do to have WinCCOA with high availabiltiy InfluxDB?

Hi,

I'm Marc, working also with Junho.

I have some more questions regarding WinccOA 3.17 with InfluxDB.
We have seen that InfluxDB server for Windows is still in experimental and that InfluxDB under Windows is not recommended for production environments (see: https://www.influxdata.com/blog/running ... n-windows/)

The InfluxDB using WinCCOA3.17 for windows is the versión of Influx in experimental?
Would you say that it is stable enough?

In a couple of occasions we have seen the 'db/winccoa' folder disappear when we where trying to visualize the data using Chronograf, and in another occasion when trying to read the data using Python (from influxdb import InfluxDBClient)

Would you say that it would be better to setup an external InfluxDB service on a Linux VM, and connect from WinccOA to the InfluxDB on that Linux machine in order to use the InfluxDB stable version?

Many thanks for your time,

The article you are referring to is nearly 2 years old.
Do you have any updated information that it is still experimental?

What does it mean in detail that the "db/wincc_oa" folder disappears?
Is it deleted from the file system?

Not sure 100%, but the last week I was in a meeting with people from InfluxDB and it seemed to me that they were speaking about Linux and MacOs.

I can also see that for the versión 2 (future version), for the moment they do not write about Windows in their 'getting started' guide (only macos, Linux, Docker and kubernetes are named):
https://v2.docs.influxdata.com/v2.0/get-started/

Could you verify with the InfluxDB people that the open source InfluxDB Windows version used by WinCCOA is stable in production?

>> ""What does it mean in detail that the "db/wincc_oa" folder disappears? Is it deleted from the file system?""
Yes, it was deleted from the file system twice; but I cannot reproduced it again, thus for the moment, don't take it into account. If I could reproduce it in the future, I would let you know.


>> ""The normal use case is that the customer uses the InfluxDB as it is delivered and installed with WinCC OA.""
I understand that the server of InfluxDB is running under Windows under the use case that you are indicating.

If you are interested in using the high availability option of InfluxDB you can install the enterprise edition on your own and connect it to WinCC OA project.
Please take into account that the enterprise edition is officially not supported. If you use it you do this on your own risk.

It is planned for the future to also support the enterprise edition. When this will be done is not defined right now.

Just for your information: When you are interested in the support of the enterprise edition please get in contact with your common WinCC OA support or your WinCC OA sales contact.
We can prepare an offer for you for a specific test using the InfluxDB enterprise edition.

Many thanks for the answers Leopold

We'll let you know if we need support for the enterprise edition.

Indeed I have the same concern. According to Influx official documentation, Windows support is experimental.
Source: https://docs.influxdata.com/influxdb/v1 ... fluxdb-oss

Also there is a similar topic in Influx DB community where a staff member says:

"...At this time we have no plans to support running InfluxDB natively on Windows." (Dec. 2019)
Source: https://community.influxdata.com/t/infl ... ows/8085/5

Could you please clarify this?

Thanks!
