If you found some error in WCS operation and this error can be reliably reproduced on your server, you can prepare an error report as described below:

Collect debug logs and traffic dump

1. Enable logging of debug information by adding to the /usr/local/FlashphonerWebCallServer/conf/flashphoner.properties settings file this line:

...

servicesudo webcallserversystemctl restart webcallserver

3. Run traffic pcap-dump using the command

sudo tcpdump -i any -s 40960 -B 10240 -w log.pcap

4. Reproduce the error you experience

5. Stop traffic dumping by pressing Ctrl+C in the window of the temrinal where tcpdump was started.

6. Find debug logs. To do this:

...

Getting logs manually

1. Go to the location of the today's logs, for example

cd /usr/local/FlashphonerWebCallServer/logs/client_logs/2018-04-19

62. 2 List all logs to the screen and sort by the modified date

...

Here
13i19gto2ob34utrfs6v2er1it-11-11-11 - is a directory containing the debug log for the first client connection
7g2hq7ah5sda3r108917v15k4c-11-10-46 - is a directory containing the debug log for the second client connection

Getting logs with report.sh script

Since build 5.2.241, it is possible to get collected logs with the following commands

sudo ./report.sh --sysinfo --conf --tar

Script gets current logs and displays the result:

Scheduled report:

* netstat
* lsof
* pmap
* jstack
* sysinfo
* conf
* tar

Progress:

[DONE] logs
[DONE] netstat
[DONE] lsof
[DONE] pmap
[DONE] jstack
[DONE] sysinfo
[DONE] conf
[DONE] tar
Report complete in 15 seconds. Check /usr/local/FlashphonerWebCallServer/report/report-2019-07-17-10-28-35

In this example, collected logs archive is here:

cd /usr/local/FlashphonerWebCallServer/

...

tools
sudo ./report.sh --sysinfo --conf --stats --tar
