Hi,
i have a tegra tx2 running mender-client on yocto zeus. I set `MENDER_UPDATE_POLL_INTERVAL_SECONDS = "0"`
because i wanted the user of the device to start update manually. Since then i experience that the update takes like 10 minutes longer where all the time is spend after reboot waiting for the server (-\> includes logs)
There is a warning about `UpdatePollIntervalSeconds is not defined` (but it is set to 0).
```auto

[10 minutes]

Successful update
```
I get those `msg="Failed to send status report to server` error every time i deploy an artifact. Also, when i manually run `mender send-inventory` i don’t have to wait those 10 minutes.
Does anyone know how these things are connected? Is it possibly a bad idea to set the polling interval to 0?

Yeah, I don’t know what would happen with this setting. @lluiscampos do you know?
I think if you just disable the Mender service and then run “mender -check-update” in your code that should accomplish what you are trying to do here.

@genericname Defining it to “0” is the same as not defining it, and the Mender client uses it’s default value which is 30 minutes.
@drewmoseley Both `-send-inventory` or `-check-update` require the mender service to be running (i.e. these cli commands just send signals to the service).
I don’t fully understand the use case. But it seems that you can achieve it setting `MENDER_UPDATE_POLL_INTERVAL_SECONDS` to something very big (one day? one week?) and then let the user manually call `mender -check-update` as @drewmoseley suggested (but with the service running).

Thanks, i wasn’t aware of that. So i will just set the intervall to some high number.
Regarding my other question, about the long update time after reboot until commit, (which i thought might be related) i have to dig a little deeper. Looks like this problem exists only with some of my artifacts.

Yes, I don’t know how could that happen. Report us back if you find out!
