Remote monitoring with GKrellm(d)

Atreja Alwinnen · 19. Februar 2017

Hi all,
i am new to OMV and Linux as well.
With the help of this forum i was able to install OMV and to configure it to fit my needs.
I get everything working (Virtualbox, Nginx, MySQL, Teamspeak, Owncloud, FTP, SMB) except remote monitoring with gkrellm.
I would like to monitor CPU usage, Memory consumption and LAN traffic with my Windows machine.
On my old Windows Home Server OS i used gkrellm to monitor it over LAN, but with debian i can not get i to work.
i installed gkrellmd via apt-get

So the deamon seems to be running, but from Windows i can not connect to it.
If i start
gkellm.exe -s 192.168.0.2 -p 19150 (wich worked for my Windows Home Server)
nothing happens. No Firewall is running on the Windows machine.
Does OMV block traffic on port 19150 by default? I made no changes to iptables or the Firewall settings under Network in the OMV control panel.

Maybee someone has a solution for this, or know an other Program, that can monitor Linux system from a Windows OS? If possible with a desktop widget.

You can use Netdata.
It's a nice, friendly program like this.

That does not look right to me. However, I could be mistaken because I have zero experience with gkrellm.
If you are looking for the right command and switches to be used, check this.

Thx for the replies,

@tinh_x7
WoW. That is an amazing Programm, i will have a look at it.
Does ist support Desktop Widgets for Windows, or does ist run only in a browser?

@iddqd
That was my starting command for the working Gkrellm connection to my Windows Home server.
So, it should work for the Debian Server too.

Maybee there is a version mismatch between the Windows Port and the Debian version of Gkrellm.

tinh_x7 · 19. Februar 2017

It runs in a Windows browser.

Dropkick Murphy · 20. Februar 2017

First, you have to verify that the port is the right one...

Code

netstat -tulpen |grep -i gkrell

FYI: Gkrellm isn't good as Netdata.

Netstat Show:

Code

netstat -tulpen |grep -i gkrell
tcp        0      0 0.0.0.0:19150           0.0.0.0:*               LISTEN      996        16699       2453/gkrellmd

So, the port seams to be correct, or am i wrong?

Dropkick Murphy · 20. Februar 2017

Port is correct. Sure that -p means Port? It should be -P imho...
The missing "r" is just a typo I think?

Atreja Alwinnen · 20. Februar 2017

You are right 'p' is wrong and 'P' is correct, but it still don't work.

Code

"C:\Program Files\GKrellM\bin\gkrellm.exe" -s 192.168.0.2 -P 19150

That is my shortcut to Start GKrellM. Without -s Option the Program start correct and monitor my lokal system.

Hummm...Doku says:

-s, --server hostnameRun in client mode by connecting to and collecting data from a gkrellmd server on hostname

IP is not a hostname...

HTH

Atreja Alwinnen · 20. Februar 2017

With the Host name i get an error message like: Unable to connect to 'Hostname':19150

Atreja Alwinnen · 21. Februar 2017

After booting my Windows Machine today the GKrellm Window appears.
The Shortcut is still set to

Code

C:\Program Files\GKrellM\bin\gkrellm.exe" -s 192.168.0.2 -P 19150

I only reinstalled Gkrellm on Windows, but it was the same version as before.

I rebootet OMV a few times yesterday but that was all Virtualbox related, nothing changed to Gkrellm.

So, i have no idea, why it is working right now.

Thx to all who helped me with my Problem.
