Hey, got some crashes with the plugin. Here are some logs:

Was it working before? As you get a connection refused error. That means that most possible your credentials are wrong. What version of the mkp do you use?

[d3sh0m3d]

No I just found a plugin for the powerfault here, I used the mkp version 2.5. Tried different credentials for the plugin but none is working. Is there any service i need to enable in the powerfault? Like SMI-S or something?

[Yogibaer75]

One other thing is the firmware of your ME4. Some days before i made a change on the special agent to support newer versions of the ME4 firmware. You can try to change this back to the old behavior.

modify the agent_dellpowervault like this

    url = "https://" + args.hostaddress
+    auth_string = hashlib.md5("{}_{}".format(
-    auth_string = hashlib.sha256("{}_{}".format(
    args.username, args.password).encode("utf-8")).hexdigest()

You see that you only need to replace the actual sha356 with the old md5. If your ME4 works after the change then you should update the firmware of your device to a newer version.

Just tried to change the hashlib to md5 but still get the same error

Then i cannot help directly. But you can have a look here at the Dell documentation of the API. https://www.dell.com/support/manuals/de-de/powervault-me4024/me4_series_cli_pub/using-a-script-to-access-the-cli?guid=guid-9ae5ccd6-a207-42df-b2f3-1e02a487a354&lang=en-us Keep in mind that you need web access from the monitoring to the Dell system.

Ok now I saw the problem, thanks for your tip with the web access, tried a curl and get a "access denied". Now open the port on the firewall and it works now. Thanks a lot.
