Disk Usage: no graph

Support

Since a day or two I don’t get a graph from the disk usage module. Any pointers on how to troubleshoot this?

Hi,

Run the following command:

/etc/e-smith/events/actions/nethserver-duc-index

I am getting this back:

 # /etc/e-smith/events/actions/nethserver-duc-index
Traceback (most recent call last):
  File "/usr/share/duc/xml2json.py", line 190, in <module>
    main()
  File "/usr/share/duc/xml2json.py", line 185, in main
    out = xml2json(input, options, strip_ns, strip)
  File "/usr/share/duc/xml2json.py", line 154, in xml2json
    return elem2json(elem, options, strip_ns=strip_ns, strip=strip)
  File "/usr/share/duc/xml2json.py", line 129, in elem2json
    size = recToDelete(child, a)
  File "/usr/share/duc/xml2json.py", line 100, in recToDelete
    size = int(obj.attrib['size'])
KeyError: 'size'

Just in case, I ran the command for a 2nd time, and got exactly the same messages back…

Hi @robb, could be an issue related to backup data path, can you provide the output of this command:

/sbin/e-smith/config getprop backup-data Mount

Hi Eduardo, thnx for the reply.
This is the ouytput for the command:

/sbin/e-smith/config getprop backup-data Mount
/mnt/backup

However, I do have the modified module for backup installed that adds backup to a webdav volume on a remote system. Could that be a cause for the graph not showing?

FYI some WebDAV server mounts may return negative values as storage left.

I have no graph at all… just a blank page… So no value whatsoever.

There is a bug on a property name (from size to size_actual). If the patch works, we will do the commit.

I have applied the proposed patch and now waiting for the result.
I checked collecd graphs and also there I see no graph for df. Is that related?

I can confirm that the patch works and after running the script again, I have back a nice looking graph. :heart_eyes:

@maddin have you tested the patch to check if your problem is related?

14

Can someone test it also on NS 6.8? (/cc @edoardo_spadoni)

Edit: issue opened https://github.com/NethServer/dev/issues/5214

15

I’d like to involve @Jim and @flatspin in this since they know the matter very well

16

I applied this changes on my NS6.8 and can’t notice any difference. My df graph worked before and seems to work fine now. Sorry.

Does this mean that the DUC module only needed a fix on NS7?

hi @edoardo_spadoni,

sry, no, and no need. Because of the wording I thought rob was talking about the visualization of the “Disk usage” - and that one does not show anything on my smartphone(chrome 55.0.2883.91 ANDROID 5.1) but under Firefox and laptop everything is fine!

So sry for false alarm!

NS 6 and N 7 use the same release of DUC, so we should fix both versions.

If you could install the package from testing and verify that everything is still fine, I will release the rpm on Monday :wink:

I will revert to old config and install from testing tomorrow. Let you know how it goes.
