Two questions

[Ernst2020]

Hi,

Two questions:

1. Is there a way to make a distinction between hardware and software probes?

2. Is logging on a hardware probe in RAM? If not, the SD card will have low life expectancy.

Regards,

Ernst

1. Where exactly? We do have a way to differentiate them on the API level thanks to env vars that hw probes set
2. Everything is in RAM, the sd card is read-only and is barely touched (Note that in certain cases we do write to some card partitions, but its something we thought out :) ). We work with an experienced IoT developer and of course we thought of such issues. And the OS itself https://www.yoctoproject.org is also designed for such use-cases, which we compile specifically for our hardware and software. It's part of what makes the probe secure, not only we don't open any ports, we don't even include most of the unrelated software that could potentially be abused.

For example here is the relevent disk config https://github.com/jsdelivr/globalping-hwprobe/blob/master/meta-jsdelivr/recipes-jsdelivr/jsdelivr-scripts/files/jsdelivr-startWorld.sh

Ok. Thanks!

1. Will need to explore the API more.
2. Excellent. Some users were worried about this.

Had a look at the API docs at https://globalping.io/docs/api.globalping.io#overview

No mention of env_vars?

Sorry I meant an internal API. Meaning we have this information but I wasn't sure where you wanted to see it or how to use it. So that we could potentially add it

[Ernst2020]

Ah. I wanted to see how many of the shipped HW probes are currently installed since only 27 new probes appeared since October 5th.
Can you easily generate an overview of which of the probes in NL are hardware based? And email me?

[MartinKolarik]

We only have that information for adopted probes, and there are 31 HW adopted probes in NL at the moment. I suspect most of them are related to the recent shipment.

If I am not missing something, every probe returns hw status to the API. There are 140 NL probes currently, 35 of them are hardware.

[Ernst2020]

Still the internal API is meant I guess?

[alexey-yarmosh]

yes(

[Ernst2020]

Any plans to add the distinction to externally visible data?

Ah, we're returning the property only if it's true, slightly confusing 😄

Generally speaking, the goal is to include data that has a clear use case and value to most users. I don't really see that here.

We could make the probe type public as part of this page jsdelivr/www.jsdelivr.com#689
I'll make a note
