No reading after reboot

[qingxiang-jia]

After restart, the applet no longer has network readings. However, if I re-add it to the desktop, it will work fine.

Same issue.

Thanks for the info. Can you please confirm if you are monitoring a single or multiple, wireless or wired connection(s)?

I've been building on a laptop with wired (via dock) and wireless connections to test dual monitoring and it seemed to be working. Yesterday i disconnected the laptop from dock and booted, had similar results you mention. I had to enter the 'Interfaces(s)' settings section to get the monitoring working again.

Add those line to the end of addSource() function:

    //2nd
    function addSources() {

...
        netDataAccumulator =        { down:  0, up:  0 };
        dbusData.subscribe(sensorList);
        //numberOfNets = count;
        numCheckedNets = checkedCount
        ready = true;
+        console.log("network_plasmoid_debug:")
+        console.log(sensorList)
    }

Reboot system, then execute command LC_ALL=C journalctl --user -b:

Feb 20 18:37:24 debian plasmashell[1863]: qml: network_plasmoid_debug:
Feb 20 18:37:24 debian plasmashell[1863]: qml: []

---

I noticed that the addSource() is not called after network state changed.

I'll try that thanks. There's code that 'should' refresh the interfaces on boot up / app start. In 'Network Interface(s) settings there is similar references to refreshing DBUS data. Strange. I'll run some tests and feedback. Ta.

[CatEricka]

This maybe has a serialization error because of:

        plasmoid.configuration.netSources = netInterfaces       // PUSH FOUND INTERFACES TO STORED SETTINGS 
        pcn = plasmoid.configuration.netSources                 // REFRESH DATA IN VARIABLE

    <group name="Network">
        <entry name="netSources" type="StringList">
            <default></default>
        </entry>
    </group>

It's StringList.

For me, the computer has two internet card, one is wired, the other is wireless. When this issue happens, the settings page has none of them, only one checkbox that cannot be interacted with.

Thanks for the help!

This maybe has a serialization error because of:

Try to serialize the object to JSON (this is just a try and should not be merged directly):

By the way, there still have a issue: if you add a network connection, there is no way to detect the new network unless poll sensors regularly

Yes, that i am aware of. If the user heads into the Network Interface(s) section it should then update the interfaces. Like you say unless the polling is constantly checking for changes it wont auto update. Something to add to the 'needs adding' list. Thanks CatEricka, i'll take a look at that code when i get a chance.

v0.3 should fix this issue. I've done a lot of testing and it works on my system. @CatEricka was absolutely correct, it was a serialisation issue. Many thanks for pointing me in the right direction and the fixes/code.

After restart, the applet no longer has network readings. However, if I re-add it to the desktop, it will work fine. Checking the box doesn't do anything unfortunately.

Seeing the same problem as @qingxiang-jia. Running plasma-applet-net-bandwidth-monitor v0.3. After I logoff and-or reboot the NIC is unchecked and no readings are shown.

My system:

After removing and readding the widget to the panel:

Anything I can test to make this great applet work?

[CatEricka]

@adrianvg You are running v0.2, because v0.3 'Network Interface' renamed to 'Network'. The installation and uninstallation of plasmoid seems to be a bit of a problem, manual removal may be works.

Huh? Taking a second look. I installed v0.3 from "Install widget from local file", after downloading it from this site.

This is v0.3:

That's why I said: "The installation and uninstallation of plasmoid seems to be a bit of a problem, manual removal may be works."

For my case the install directory is $HOME/.local/share/plasma/plasmoids/.

[adrianvg]

Ok, now I got the correct version. Needed some work to uninstall the old version and getting the new one in.

The network tab seems weird though. Nothing is listed, but the widget still seems to read from something.

Will try to logoff and reboot and see if it sticks.

[adrianvg]

Logged off and on again and the readings still work! And now also shows the NIC.

Logging off and rebooting same as above - I'm happy. Thanks to you all; @CatEricka, @LeeVD !

Maybe there is some error in the configuration file, open file $HOME/.config/plasma-org.kde.plasma.desktop-appletsrc if it exists, then search netSources. Delete this entry, and then re-add the widget.

v0.3 works fine on my desktop, mine version of netSources is:

[Containments][1][Applets][62][Configuration][Network]
netSources=[{"path":"network/enp13s0"\\,"name":"Wired connection 1"\\,"index":8\\,"checked":true}]

Works fine for me now. Seems the logoff was needed to settle things. See above post!

Yah, sometimes need logoff; I don't really understand why, but at least the install and uninstall of plasmoid have had this issue for the last few months. Until last week, the size and position of widgets would be messed up every time I loggin. At least this week the widgets aren't run around anymore. (My OS: Debian bookworm)

[CatEricka]

Just in case someone needs this: There was a issue with the previous config file, v0.3 changed the format of the config format (it is now an escaped JSON string) in order to properly serialize netSource object to the config file. The code of v0.3 was not considered for compatibility issues (as the old code was actually incorrect and the netSource object was never properly serialized, which is why #11 happened), so some conflicts may need to be handled manually.

The config file for plasmoid is $HOME/.config/plasma-org.kde.plasma.desktop-appletsrc, this file also stores all desktop custom settings, including desktop icons.

It should be noted that this is not the issue mentioned above, but a issue of plasma itself.

@LeeVD Connecting with VPN is no problem, shows speed as expected.

[LeeVD]

In my testing I saw the install and uninstall wasn't always accurate. Last attempt i used plasmapkg2 to install the plasmoid v0.3 file which worked, after I uploaded v0.3 to pling/kde store and i went to the desktop section to get widgets/plasmoids it showed it needed upgrading. I'm not sure of the expected plasma way to handle upgrading the software, if anyone knows that please let me know.

It seems a reboot/log off may be necessary for the new version to work correctly. I'll add that to the read me section. Due to code rewrites and future additions, i sometimes change the variable types, I'm sure that doesn't help either!

Thanks for the feedback @adrianvg @CatEricka. I'm glad things are finally working...ish :)
