Best browser for Zabbix Kiosk

[kekkykekke]

This would rather go to the "discussion" category if there would be any. I just put it here.

The goal of this discussion is to look for reliable browser displaying Zabbix on a kiosk machine 24/7, aka some browsers with no memory leak, overload, swapping , crashing, stuck whatnot.

So far I did not find a good one.

Here are the ones I tried:

• Firefox
• Netsurf (not working)
• Dillo (not working)
• Artic fox
• Palemoon

The thing about with the firefox vairants that over time they start swapping, pulling the cpu like crazy, in case of temporary network connectivity loss between the kiosk machine and the zabbix server, they are not able to autoreconnect (zabbix screen will be just showing loading on all charts forever). The last issue can be compensated with autoreload addons which reload firefox periodically eg in every 5 minutes so even if it would stuck it will keep on displaying.

Suggstions?

I'm bumping this up as I start giving up on this completely

No matter what hardware/browser/os I try the end result always seems to be the same Zabbix kills any browser on the long run.

This wouldn't even matter if there would be a proper way to restart the browsers, since it's a kiosk all you would might notice that the browser restarts once in a while then opens however if Firefox crashes for example depending on the versions it will always nag you to either restore the pages when you reopen regardless that you specifically set that in the config or with never versions it will say "Tab Crashed Gah" no way around telling him that I do not care if it's crashed just restore it.

If it would normally terminate aka close then it would restore the tab without telling you a thing...

I'm not planning on replacing Zabbix with any other monitoring system just looking for some alternative option to accomplish what I want.

Now I even start thinking on dumping the whole SCREEN as a static html with Selenium or some tool into a html file and use some super simple browser like Netsurf to keep reopening that periodically to have a real kiosk feeling.

Any suggestions???

I'm running zabbix on a kiosk which is just running chrome. I have a shortcut that opens the zabbix dashboard in kiosk and fullscreen. I then use task scheduler to open the shortcut on boot. It then kills chrome at 3am and opens the shortcut again shortly after. 99% of the time the session is retained and logs in automatically. For us, not being able to see the dashboard on "the big screen" for 30 seconds or so isn't a big deal. For us, the only thing going on at 3am is backups or scheduled maintenance.

Do you mind to share what Zabbix version you running there? Mine is Zabbix 4.0.1

I really reluctant to update it as I don't need any feature but if the new ones improve the Web UI stability and lower the overhead for client computers (what I strongly doubt) I will give a shot to upgrade it.

This version is coming from: 29 October 2018, I also tried to match it with older browsers come out around that time not much luck.

I give a shot to an older version of Chromium now but the problem is there is no auto reload addon for it, which is needed for me as I explained the WAN link to the Zabbix server can drop out and then it loads into a forever loading loop the autoreloader helps on this one.

I would just like to say a thank you for you
The situation improved hell of a lot.

UVM: pid 57438 (firefox), uid 1000 killed: out of swap
UVM: pid 90080 (firefox), uid 1000 killed: out of swap

Firefox still crashes eventually but it takes about 4 days and the graphs are way more beautiful and responsive. I gave the box 5GB swap. I restart the whole DM every night at 3 AM, this is "just good enough" for me.

Well I would just really add to this that the high CPU usage occurs when the remote server becomes unreachable it seems the client side JS is killing the machine no matter what hardware or browser you put underneath it:

cpu MHz : 2893.292
cpu MHz : 2893.307
cpu MHz : 2893.291
cpu MHz : 2893.259

Literally it pulls the CPU on 100%
This is really something to fix in new releases if the connection is broken there is no reason to hammer the machine just wait and retry.

You can submit a bug about it, if you can describe options to reproduce it etc...
