Telemetry Collection Failure

Question

Hello all, we are experiencing telemetry failure as shown in image below. The second image below says that there is a credential issue but I checked and the credentials are fine. I even reinputted the credenetials on Secure Connect Gateway and retested telemetry but no luck. Also, telemetry is failing on servers with iDRAC 7 and 8. I don't think iDRAC version is the cause since servers with iDRAC version 8 have telemetry working fine. Under iDRAC settings -> Network -> services, the configuration is the same for the working and non working servers. Also on iDRAC there is no mention of WSMAN protocol so I couldn't do anything about as suggested by the error. I really doubt that the login credentials are to blame here as I am able to login fine as an admin. Any clues or leads are appreciated, thank you!

@DELL-Joey C​  Hello so the resolution for my case appears to be resetting the SCG VM. Also initially I did not have a credential profile assigned to the telemetry collection process but it was only after resetting the SCG VM that telemetry data collection worked across all devices. I appreciate all the help troubleshooting!

Hi,

I gave a rought look at the compatibility guide here https://www.dell.com/support/manuals/en-us/secure-connect-gateway/scg_5.x_ve_sm/12th-generation-poweredge-servers?guid=guid-5fcf90c1-1bc5-41a1-b331-c10059a01b12&lang=en-us seems that the iDRAC version should be sufficient to get compatible with SCG.

Next is to check if the ports are open for different protocols: https://www.dell.com/support/manuals/en-us/secure-connect-gateway/scg_5.x_ve_sm/supported-servers?guid=guid-59624dd9-861d-457b-b358-87a9a01f6e6a&lang=en-us

After verifying the ports, you may try log in to the SCG virtual appliance CLI via SSH using your root credentials, run a ping test to the target device. Since you the error points to WSMAN, try curl -k -v https://<target_device_IP>:443

Also, can you check if the servers that are having issues, are installed with iDRAC Service Module.

Hello, thank you for the response, please see below for requested information:

1) Please see direct messages.

2)

for IP 10.12.14.107, that is PowerEdge R520, with iDRAC 7 version 2.65.65.65

for IP 10.12.14.27 that is PowerEdge R530, with iDRAC 8 version 2.86.86.86

for IP 10.12.14.154 that is NX3230 with iDRAC 8 version 2.83.83.83

I want to note that we have a NX3230 with iDRAC 8 version 2.83.83.83 that had successful (partial) collection of telemetry so I'm not sure if iDRAC version or Server type is the issue.

@DELL-Joey C​  Hello thank you for the detailed response 1) The compatibility matrix shows no issue with my setup 2) I tested the ports using Test-NetConnection -ComputerName 'host_name' -Port 443 mentioned in the link and port 135 is open on the target device. Port 22 and 443 are closed according to this command 3) I also tried the curl command you mentioned via command line and the output shows that: TCP reachability ✓ TLS handshake (TLSv1.2, cipher negotiation, certificate exchange) ✓ The web server responds correctly (302 redirect to login page) ✓ Also service module is not installed on any of the devices' iDRAC. I tested on another device and it was partially successful for telemetry data collection (also iDRAC8). Appreciate the continued support, will keep trying telemetry data collection on other devices to find a pattern
