simultaneous stream limit.

[tokensolution]

Hello all, have the latest ZM plugin running with 5 Reolink cameras, on both Firefox and Chrome I can only watch 4 streams at a time (despite documentation saying I should see 6 on Chrome- I'm sure things have changed since the documentation).

Since most all documentation on ZoneMinder is in regards to being installed on some bare metal nix build, and I'm not a FreeNAS wiz, how do I go about either of these mitigations below?

Multi-Port, Storage Areas and more

Recent ZM versions (I think ZM 1.32+) added a feature that allows you to stream as many monitors as possible and not be limited to the…

I was poking around and it looks like zoneminder uses nginx for the FreeNAS plugin version.

Or better yet, this trick:

https://www.freebsd.org/doc/handbook/firewalls-ipfw.html You're looking for the section on port redirection to use the second option (iptables is a linux thing).

It's potentially simple, but it's a lot more than I have time to work through to prepare the commands for you.

This is still an issue. The zoneminder plugin is great, but without multiport enabled...you can only watch 4 cameras at once.

This is what I am doing right now:

Did not really help at all. This is crazy, I just want to see all my cameras in one browser

I can access the cams, but what is the point, I have to open a browser for 4 cams each time? If I have 12 cams, I need 3 browsers open to see montage correctly?

My old zoneminder I can see my 6 cams just fine......this new version..why did they switch to a different type of viewing?

I don't think you read the OP and my update...

It seems to me you're not doing that.

If you read this article, you would see exactly why:

So the FreeNAS zoneminder plugin is kinda broke, but still works great. I spent so much time messing w/ multiport settings/etc. No matter what I did I could not get more then 4 cams to stream.

Two changes need to be done to stream more than four cameras. The multi port stuff as talked about here, but there are not enough fastcgi processes avail to stream more then 4 cams.

fcgiwrap_flags was set to 4. For now I upped it to 10:

Everything is working fine now. I could not get multiport to work, but after doing the above, it works fine.

To get muliport to work I just followed the instructions after that and added some listen directives:

And fixed my zoneminder config:

All is well. Like I said, it took me a few hours to realize why mutiport is not working. I think I will file a bug soon to increase fcgi children in rc.conf

TrueNAS does not have any way to have a list of editable variables for a package? This would be a good place to have one. Where you edit in the gui, and it seds/sets in the shell?

In an effort to figure things out I also did this:

I increased pm.max_children to 50:

I do not remember what it was.

I have not changed that back yet in my config.

I don't this it in my working config now, but I also experimented with setting fastcgi_buffering off and also setting size to zero. I was getting this:

2021/01/05 11:26:05 [warn] 26709#100726: *91 an upstream response is buffered to a temporary file /var/tmp/nginx/fastcgi_temp/4/00/0000000004 while reading upstream

That was the hint I needed to know something was up w/ fastcgi.

Where do I report this issue? Is there a git someone could point me to?

 

[webdawg]

Is this correct?: https://github.com/freenas/iocage-plugin-zoneminder

 

[webdawg]

Is the forum dead?

I guess?

I pushed the changes: https://github.com/freenas/iocage-plugin-zoneminder/pull/12
