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:

client_log_level=DEBUG

2. Restart WCS with the command:

service webcallserver restart

3. Run traffic pcap-dump using the command

tcpdump -i any -s 0 -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.

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

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

ls -lt

Sample result:

Getting logs with report.sh script

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

cd /usr/local/FlashphonerWebCallServer/tools
sudo ./report.sh --sysinfo --conf --tar

Script gets current logs and displays the result:

Scheduled report:

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

Progress:
