I want to change the WMI Volume Sensor primary Channel to "Free Bytes" per default for every existing and new sensors. Is it possible?
I afraid that it is not possible to change the primary channels in multiple, already existing sensors at the same time, nor to set it for future sensors, sorry.
is it possible to change the default for new sensors? So every new sensor will have "Free Bytes" as default? And is it possible to set default limits for new created channels?
You can do this by creating a device-template based on device having a WMI Volume Sensor configured as you like it. When using this template to create another device and apply this template, it will create WMI Volume Sensors with the same channel as primary and the limits you configured there.
I don't think it's possible since the WMI Volume Sensor is excluded from device-templates.
Ah, now you got me :) However I had success creating a template with the sensor in it....I'll see to it, it is possible that documentation needs to be updated.
@tsebast: Sorry, my bad, by mistake I chose the wrong sensor when creating the template, so you and the manual are right, this sensor does not work with template, so there's no way to change those defaults. Sorry again for the confusion.
Thank you Erhard. Can you give me a hint why it's not possible - and not planned - to change defaults for channels and limits? Would be a huge relief!
You're welcome. Thing is on one hand it's a UI issue, since there are a lot of different sensor types, each one would need its own "customizing interface", because channels can differ hugely between sensor types and it wouldn't make sense to implement such a customizing ability only for a selected few, it's either all or none.
What will probably make more sense would be improving "mechanisms" that are already in place like Multi-Edit and usage of device templates to provide more flexibility in the future, though complexity is an issue here, depending on the sensor type. It's currently not something we put a priority on. In the end it's all about resources and we have to plan very carefully on which topics our precious developers are putting their focus on :)
