Live activity monitoring remains blank

Before posting something, READ the changelog, WATCH the videos, howto and provide following:
Your install is: Bare metal, ESXi, what CPU model, RAM, HD, what EVE version you have, output of the uname -a and any other info that might help us faster.

Live activity monitoring remains blank

Post by mamakos » Thu Jan 06, 2022 10:05 pm

Hello,
On my lab I cant get any live interface utilization diplayed. it remains blank

MX-2 is on Master EVE-NG node
MX-1 is on Satellite EVE-NG note
7750 is on Satellite EVE-NG node

Is there a missing package on the master ?
Wireshark capture works fine
Link Quality management is also working fine


And the eve-ng-pro is the latest. On a previous Pro installation it was working fine( but I only had one master device at that time)
I already stopped/closed/restarted the lab.
it isn't working for any of the links (either regular nodes interface, nore the management interface like FXP0 on Juniper nodes)

On the screenshot, you'll see that pings are geting through ge-0/0/0 on MX-2, which is the link that is supervised.

And on the master here is what docker I have

No issues, Graph works on vMX master or sat

Well I did not ask IF it were working on YOUR side but WHY it did not on MY server.
As I stated, I know it should work as I saw it working in the past on an other setup. So somewhat this is something broken on my setup or a limitation due to HW or SW

So what could possibly go wrong here ?
What can I check for ?
I already stopped/closed/restart the lab and each node.

Thank you

Check if satellite has same version as master

Code: Select all

dpkg -l eve-agent
also you can run on master

Code: Select all

unl_wrapper -a updatesat
it will sync master version with sat

and does master only works with graph or not?

Yes, of course, satellite and master do have the same EVE relase (the latest, see below).

They are both baremetal R640 with slight different HW (CPU/NIC)

Link activity does not work at all in this lab, :
- neither on links from VM on master to "cloud_on_master"
- nore on links from VM on satellite to "cloud_on_master"
- nore on master side for master to satellite link
- nore on satellite side for master to satellite link

On a previous setup I had the graphs on the master side only as far as I remember. I do no recall if I had an issue on the satellite or if I just did not check interfaces on the satellite

I used another lab (which I tested on the other EVE-NG pro setup, i.e. same JunOs/Timos VM relases) and it still does not display anything (all nodes are hosted on the master in this lab). So there must be something wront on my current setup :(

Here are the HW description + dpkg status on both hosts

Uldis,

PS : I already cleared my web browser's cookies/cache content, tried another lab. I tried in native console and HTML5 console

I found an interesting error message in /opt/unetlab/data/Logs/ssl-error.log each time I try to get interfaces statistics

Code: Select all

[Tue Jan 11 22:14:34.617669 2022] [proxy:error] [pid 74729] (111)Connection refused: AH00957: HTTP: attempt to connect to 127.0.0.1:19999 (*) failed

And when trying with HTML5 DESKTOP, I get the same error messages
[Tue Jan 11 22:24:29.663253 2022] [proxy:error] [pid 74729] (111)Connection refused: AH00957: HTTP: attempt to connect to 127.0.0.1:19999 (*) failed

So the reverse proxy is not the problem. My EVE-NG setup does have a problem.

I restarted the master (and satellites) and voilà it works !
And now I do have a 19999 listening socket

Code: Select all

root@muztc628:~# netstat -anp | grep 199
tcp        0      0 0.0.0.0:19999           0.0.0.0:*               LISTEN      4443/netdata

So can you tell me how to restart the process that is responsible for it without rebooting the whole setup ?
