OpenMediaVault integration issues

I'm trying to setup the OMV integration for system health monitoring, but I keep getting errors, I have created a user for the integration, I have also tested with the admin user, tried both external and internal urls (I suspect the external url was giving issues due to authelia) and it's still not working, this is the full object that appears in the console when loading: https://privatebin.io/?77d1d4784f79ea2b#25GYjqJEGhMppZKSuLojHjZT9bTdnTF8w3MSrN3pH8rJ I have installed the plugin My full docker compose: https://privatebin.io/?6bbef3ff2ebe26e2#27NvLvLxTZt7NAPTsZQvbo3We85feosBUTjLNzanFVNP Homarr version 1.17.0 Running on OMV 7.7.4-1 (Sandworm)

Solution:

So the account needs probably more permissions 😄

Ok, I have somehow managed to get it working, but after a reboot of the system it is back to not working

Nice! but I'm more concerned with the error at the end since that's the one that apears when I reload the dashboard with the heath monitoring present

This error occurs because the response of the api does not match our expected format. we expect the following:

z.object({
  response: z.object({
    version: z.string(),
    cpuModelName: z.string(),
    cpuUtilization: z.number(),
    memUsed: z.string(),
    memAvailable: z.string(),
    uptime: z.number(),
    loadAverage: z.object({
      "1min": z.number(),
      "5min": z.number(),
      "15min": z.number(),
    }),
    rebootRequired: z.boolean(),
    availablePkgUpdates: z.number(),
  }),
})

z.object({
  response: z.object({
    version: z.string(),
    cpuModelName: z.string(),
    cpuUtilization: z.number(),
    memUsed: z.string(),
    memAvailable: z.string(),
    uptime: z.number(),
    loadAverage: z.object({
      "1min": z.number(),
      "5min": z.number(),
      "15min": z.number(),
    }),
    rebootRequired: z.boolean(),
    availablePkgUpdates: z.number(),
  }),
})

When calling system.getInformation Not sure why, but maybe you have something of the features disabled / not enabled that were expected

Manicraft1001•4mo ago

@Meierschlumpf can we log more info from the zod validator?

Meierschlumpf•4mo ago

My changes regarding the test-connection changes, that I'm working on, will make it a lot easier to do so yes.

TheRedCyclopsOP•4mo ago

What is the exact call you're making? maybe I can manually trigger it to see the issue, I am using a separate account for the integration, but I have also tried with the default admin

Meierschlumpf•4mo ago

We make a POST request to /rpc.php with the following body:

{
  "service": "system",
  "method": "getInformation"
}

{
  "service": "system",
  "method": "getInformation"
}

and the required authentication through headers / cookies, depending on your setup

TheRedCyclopsOP•4mo ago

Dang, I'm really struggling to get it to accept the auth, could you give me any extra directions on what I should do?, this is my current command:

 curl -X POST -d '{
  "service": "system",
  "method": "getInformation"
}' -b ~/downloads/cookies.txt http://omv.local/rpc.php

 curl -X POST -d '{
  "service": "system",
  "method": "getInformation"
}' -b ~/downloads/cookies.txt http://omv.local/rpc.php

Where cookies.txt is the dump from the browser after logging in, for some reason it's still giving me the Session not authenticated error

Meierschlumpf•4mo ago

If you have cookie auth then they should be named OPENMEDIAVAULT-SESSIONID and OPENMEDIAVAULT-LOGIN (both like this or both with X- as prefix) Or if it is header authentication you can use the header with X-OPENMEDIAVAULT-SESSIONID

TheRedCyclopsOP•4mo ago

checking the file they are there, but OPENMEDIAVAULT-LOGIN has a dash at the end followed by a long seemingly random string

Meierschlumpf•4mo ago

That's weird that it has a dash at the end 🤔

TheRedCyclopsOP•4mo ago

OPENMEDIAVAULT-LOGIN-%242y%2410%24VYXgKFa6hIkpyGz6[more random string...] also, there are two ohh, wait, I've just realized I've dumped it from the access through the reverse proxy instead of direct as I'm doing on the command line

Meierschlumpf•4mo ago

Okay the %24 are probably encoded $

Does that look good?

Meierschlumpf•4mo ago

It looks like a response from omv yes, let me check quickly Hmm that looks correct

TheRedCyclopsOP•4mo ago

It did take a full 4 seconds to proccess 6 on a second request

Meierschlumpf•4mo ago

Okay, this should not really matter as we got the Invalid system information response error and not a timeout or similar

TheRedCyclopsOP•4mo ago

Ohh, wait I've got it (I think)

Meierschlumpf•4mo ago

Maybe the response we get back through homarr is the one that you get when you are unauthorized. Can you check through updating the integrations secrets? Okay if you have it even better!

TheRedCyclopsOP•4mo ago

using the account I created for the integration only this appears:

{
  "response": {
    "ts": 1746133957,
    "time": "Thu 01 May 2025 11:12:37 PM CEST",
    "hostname": "omv.internal"
  },
  "error": null
}

    "time": "Thu 01 May 2025 11:12:37 PM CEST",
    "hostname": "omv.internal"
  },
  "error": null
}

Meierschlumpf•4mo ago

Oh I see

Solution

Meierschlumpf•4mo ago

So the account needs probably more permissions 😄

TheRedCyclopsOP•4mo ago

I thought I had also tried with the admin account but it must not have updated for some reason any idea on what groups it needs to be part of? I'm seeing in the OMV wiki that any user on the openmediavault-admin group is a web interface administrator, but ideally I would like to not give a user that's just there to get stats admin permisions over the whole system

Meierschlumpf•4mo ago

Maybe with SNMP you can make the data read only? Other than that it states that it is only available to the admin group But SNMP is a seperat protocol on port 161 it seems that we don't support So it's probably only the admin credentials way that seems to work, except you want to touch ACL rules, which is not recommended

TheRedCyclopsOP•4mo ago

then there is really no point to having a separate user?

Meierschlumpf•4mo ago

I guess not really

TheRedCyclopsOP•4mo ago

It seems to still be failing

Meierschlumpf•4mo ago

Except maybe to sign in with only him to only have read rights by default

TheRedCyclopsOP•4mo ago

same error I think:

and this time I'm using the default admin user I've even made sure with curl with the exact same address and details the exact command used for testing that works is:

curl -X POST -d '{"service": "system", "method": "getInformation"}' -b ~/downloads/cookies.txt http://192.168.100.55/rpc.php | yq

Meierschlumpf•4mo ago

I think this one is on me. We have a sessionStore which stores the used secrets for calling the api in a cache so we don't authenticate all 5 seconds. But we don't invalidate it when other credentials are used... If possible you can remove the session in omv / wait until the session expires And then we should make changes so that the stored sessions are for specific credentials

TheRedCyclopsOP•4mo ago

That would definitely explain why it worked previously when I switched it to the unprivileged account Does just deleting the user work? Yes it does

Meierschlumpf•4mo ago

It should as then your api will respond with status code 401 (i suspect) and if this is the case we authenticate again

TheRedCyclopsOP•4mo ago

now the integration is working finally and since we know why it failed previously we can (probably) discard any hidden timebombs

Meierschlumpf•4mo ago

Okay great, so best would be if we 1. add more details to the Invalid system information response 2. add documentation that admin permissions are required as it otherwise does not show enough informations 3. we invalidate the credentials of integrations when the testConnectionAsync is run

TheRedCyclopsOP•4mo ago

I understand the first two, but shouldn't the credentials only be invalidated when the integration is modified?

Meierschlumpf•4mo ago

Yes that would make even more sense Okay but great, I suggest I'll create an issue for invalidating the credentials of the session store and one for the admin permissions for omv (the first one I'm already working on with some other changes)

TheRedCyclopsOP•4mo ago

sure, go for it, thanks for all the help and for the great dashboard

Meierschlumpf•4mo ago

You're welcome, have a good night

TheRedCyclopsOP•4mo ago

You too, shall I mark this issue as solved?
