How to find out why a stream from camera stopped showing output?

Post by linforpros »

Hello,
I would like to learn why one of the four cameras that are installed in the system stopped showing output.
To find out I did the following:

1. checked "top" and only three zmc processes are active [?]
2. checked ps aux|grep zmc and there are four processes active [OK]
3. Pinged all four cameras and they respond to ping with 0% packet lost [OK]
4. checked arp to make sure that things work on the hardware level [OK]
5. Finally checked logs from within zoneminder narrowing to zmc_m12 (the malfunctioning cam) [?]
6. The zm web console shows all cameras as "green" [OK]

The zm log do say some meaningful things but the interpretation is hard. See snippet below. Apologies for selective log.

I cannot however come to a conclusion where the culprit might be. The camera does not show anything. Just dead browser icon.
Below some of the tests that were run.

I probably could reboot the system nd things might just come back to normal but the point is I would like to diagnose the problem.
What else can I do to find out more?

Thank for any hints.
Linux 4.4.9-300.fc23.x86_64
Fedora release 23 (Twenty Three)
zoneminder-1.29.0-3.fc23.x86_64

You could be out of memory. Do a "dd" to see if anything is near 100% especially your tmpfs. Lower camera resolution to fix...

Thank you for giving a hint to find out more. Do you make anything out of this:

Code: Select all

df -h
Filesystem               Size  Used Avail Use% Mounted on
devtmpfs                 970M     0  970M   0% /dev
tmpfs                    978M  207M  772M  22% /dev/shm
tmpfs                    978M  672K  978M   1% /run
tmpfs                    978M     0  978M   0% /sys/fs/cgroup
/dev/mapper/fedora-root   49G  5.3G   44G  11% /
tmpfs                    978M  4.0K  978M   1% /tmp
/dev/sda1                477M  148M  300M  34% /boot
/dev/mapper/fedora-home   24G   54M   24G   1% /home
tmpfs                    196M     0  196M   0% /run/user/1000
It seems that the system is on the safe side when it comes to memory consumption.


I just managed to catch the server with "green" Log. And there is no "South_Window" camera - as I labeled it - in the log at all. How come the system is "green"? It should be in the alarm state that one of the cameras are not working as designed. What else can I do?

See below:

Re: How to find out why a stream from camera stopped showing output?

Post by linforpros »

I was unable to find out why the camera stopped showing output. After a reboot things returned back to normal. South_Window camera is good now.
A reboot proves that in was in the zoneminder where the problem was. So the issue remains uresolved for now. If the problem persists I will revisit it and troubleshoot it again.
