Hi atlas folks, is there a way to get the operating system uptime of a probe? The reason I'm wondering is that I want to differentiate a shut down probe (i.e. power outage, operator reasons) from a disconnected probe (i.e. Internet connectivity lost). Depending on the goal of a measurement these two cases should be considered differently. The one way I think this is currently possible is to look for results that the probe has uploaded from its local buffer after it has regained network connectivity. In case of a disconnected probe, there will be measurement results during the outage but not if the probe was fully turned off. This approach is however a bit hacky and requires you to query the event log and align that with the measurement results. Depending on how often your measurement runs, you might have to query data from the built-ins as well. Of course you can always try to look at probes from the same region/AS and see if they faced outages, but this requires a lot of additional data to be queried and will not be 100% accurate. I understand that this probably is only relevant for a subset of all probes, but also collecting the uptime as tracked by the OS would be a simple fix to easily differenciate between different disconnect reasons.
