iotedge check with confusing results

[Suizi11]

Expected Behavior

When running the iotedge check --verbose I want to have some details WHY checks were skipped.

It would be nice when running iotedge check-list is executed that checks which are required for connectivity checks are "marked" somehow.

Current Behavior

Check without --verbose

    container-connect-upstream-mqtt
    "
eval $check_iotedge_cmd

Result:

Configuration checks (aziot-identity-service)
---------------------------------------------
√ identityd configuration is well-formed - OK

Connectivity checks (aziot-identity-service)
--------------------------------------------
√ host can connect to and perform TLS handshake with iothub AMQP port - OK
√ host can connect to and perform TLS handshake with iothub HTTPS / WebSockets port - OK
√ host can connect to and perform TLS handshake with DPS endpoint - OK

Configuration checks
--------------------
√ aziot-edged configuration is well-formed - OK

Connectivity checks
-------------------
5 check(s) succeeded.
2 check(s) were skipped due to errors from other checks. Re-run with --verbose for more details.

Check with --verbose delivers exactly the same result

Steps to Reproduce

Provide a detailed set of steps to reproduce the bug.

1. Execute command shown in "current behavior"

Context (Environment)

Output of iotedge check

I found out that if special --dont-run are missing, the results are quite confusing. E.g. if I remove container-engine-uri then everything is clear.

Device Information

• Host OS [e.g. Ubuntu 18.04, Windows Server IoT 2019]: CentOS 8 (RHEL 8)
• Architecture [e.g. amd64, arm32, arm64]: amd64
• Container OS [e.g. Linux containers, Windows containers]: Linux containers, of course

Runtime Versions

• aziot-edged [run iotedge version]: 1.4.3
• Edge Agent [image tag (e.g. 1.0.0)]: 1.4.7
• Edge Hub [image tag (e.g. 1.0.0)]: 1.4.7
• Docker/Moby [run docker version]: 20.10.11+azure-2

Note: when using Windows containers on Windows, run docker -H npipe:////./pipe/iotedge_moby_engine version instead

@Suizi11 I'm not sure I understand the issue. I tried iotedge check --verbose on a machine and see this output for the Connectivity checks:

...
Connectivity checks
-------------------
√ container on the default network can connect to upstream AMQP port - OK
√ container on the default network can connect to upstream HTTPS / WebSockets port - OK
√ container on the default network can connect to upstream MQTT port - OK
    skipping because of not required in this configuration
√ container on the IoT Edge module network can connect to upstream AMQP port - OK
√ container on the IoT Edge module network can connect to upstream HTTPS / WebSockets port - OK
√ container on the IoT Edge module network can connect to upstream MQTT port - OK
    skipping because of not required in this configuration
32 check(s) succeeded.
3 check(s) raised warnings.
2 check(s) were skipped due to errors from other checks.

Are you saying that when you add the '--verbose' flag you don't see anything like above where it says 'skipping because of ...'?

[Suizi11]

@micahl you're right. Just execute the same command as in my "Current Behavior" section. There's no "skipping because of ...", although executed WITH --verbose. So, I've no clue which check has been skipped.

[micahl]

@Suizi11 Stepping back for a minute... why do you want to exclude running all of those checks?

This issue is being marked as stale because it has been open for 30 days with no activity.

@micahl I'm so sorry for this very, very late response

why: we've more than 5k devices in the field with 5k different local network conditions e.g. firewalls, that's why we execute a connectivity check regularly on the host level (OS), during this check we also want to iotedge check the connectivity to Azure IoT Hub to inform the customer if there's something not working within the local network
