 +
 +Use the "ngrep" tool : 
 +<code>
 +ngrep
 +</code>
 +
 +<code>
 +ngrep -d lo -s 1500 port 5038 -T
 +</code>
 +==== Monitor memory/CPU ====
 +
 +A very simple way to follow the memory and CPU indicators :
 +
 +<code>
 +root# top -b -d 5 -p $(pidof voximald) | awk -v OFS="," '$1+0>0 {print strftime("%Y-%m-%d %H:%M:%S"),$1,$NF,$5,$6,$7,$9,$10; fflush() }' | tee datas.csv

 </code> </code>
 +
 +==== Set the right TimeZone ====
 +
 +Install the NTP package to synchronize your server to the world's time.
 +
 +<code>
 +#timedatectl set-timezone America/New_York

 +
 +or, for french servers,
 +
 +<code>

 +</code>
 +
 +or automatically,
 +
 +<code>
 +#dpkg-reconfigure tzdata
 +</code>
 +
 +==== Monitor the file descriptors ====
 +
 +List the file descriptors used by a process :
 +
 +<code>
 +# ls -l /proc/[PID]/fd
 +</code>
 +
 +==== Generate a CallStacks or Coredumps ====
 +
 +Generate the threads stacks or a coredump file for the process (voximald) :
 +
 +<code>
 +gdb -ex "thread apply all bt" --batch /usr/sbin/asterisk $(pidof asterisk) > /var/log/voximal/backtrace-asterisk-$(date +%s).txt
 +
 +gdb -ex "thread apply all bt" --batch /usr/sbin/voximald $(pidof voximald) > /var/log/voximal/backtrace-voximald-$(date +%s).txt
 +
 +gdb /usr/sbin/asterisk$(pidof asterisk) -ex "gcore /tmp/asterisk-$(date +%s).core" --batch
 +
 +gdb /usr/sbin/voximald $(pidof voximald) -ex "gcore /tmp/voximald-$(date +%s).core" --batch
 +</code>
 +
 +==== Execute the Asterisk with GDB (debugger) ====
 +
 +Launch the Asterisk process with the debugger (gdb) :
 +
 +<code>
 +gdb -ex=r --args asterisk -cvvvvvv -U asterisk -G asterisk
 +</code>
 +
 +==== Attach the GDB (debugger) to the Asterisk ====
 +
 +Launch the debugger process and attach to the running Asterisk :
 +
 +<code>
 +gdb /usr/sbin/asterisk $(pidof asterisk) -iex "set pagination off" -ex cont
