====== Monitoring traffic distribution by class ======

SSG allows traffic distribution by class to be monitored.

1. Enable traffic prioritization. For the example, we will use the following prioritization rules:
<code bash>
dns cs0
http cs0
https cs0
Bittorrent cs7
ICMP cs0
TCP Unknown cs7
GOOGLEVIDEO cs1
default cs2
</code>

2. In the ''/etc/dpi/fastdpi.conf'' configuration, set the parameter:
<code bash>dbg_log_mask=0x4</code>

3. Enable common channel polysync (the example shown is polysync with full channel width restriction):
<code bash>
htb_inbound_root=rate 1300mbit 
htb_inbound_class0=rate 8bit ceil 1300mbit
htb_inbound_class1=rate 8bit ceil 1300mbit
htb_inbound_class2=rate 8bit ceil 1300mbit
htb_inbound_class3=rate 8bit ceil 1300mbit
htb_inbound_class4=rate 8bit ceil 1300mbit
htb_inbound_class5=rate 8bit ceil 1300mbit
htb_inbound_class6=rate 8bit  ceil 1300mbit
htb_inbound_class7=rate 8bit  ceil 1300mbit
htb_root=rate 1300mbit 
htb_class0=rate 8bit ceil 1300mbit
htb_class1=rate 8bit ceil 1300mbit
htb_class2=rate 8bit ceil 1300mbit
htb_class3=rate 8bit ceil 1300mbit
htb_class4=rate 8bit ceil 1300mbit
htb_class5=rate 8bit ceil 1300mbit
htb_class6=rate 8bit  ceil 1300mbit
htb_class7=rate 8bit  ceil 1300mbit
</code>

4. Update the configuration:
<code bash>
service fastdpi reload
</code>

<note important>
If polyscing for a shared channel is applied for the first time, you must restart the service:
<code bash>service fastdpi restart</code>
</note>

5. Use the following custom settings for the zabbix agent installed on the SSG:
{{ :dpi:dpi_components:platform:mon_stat:ssg_userparams.conf |}}

6. Import the template to the Zabbix server as described in the section [[dpi:dpi_components:platform:mon_stat#server_setup|"Monitoring via SNMP agent"]]:
{{ :dpi:dpi_components:platform:mon_stat:zbx_export_templates.xml |}}

<note important>If necessary, change the interface names in the template and in the custom parameter file</note>

===== View flow and protocol statistics =====
==== By flow ====
  - IPv4/IPv6 
  - protocol type: 0 - IPv4, 1 - IPv6
  - total allocated records 
  - a queue with a short lifespan:\\
    - occupied records\\
    - reusable\\
    - difference 3.1 - 3.2 (number of active flows)\\
  - also for the long line\\
  - also total\\
//Example://\\
<code ini>fdpi_ctrl stat --flow
IPv4 0 6784000 834 814 20 0 0 0 834 814 20</code>

==== By protocols ====
  - internal index of protocol statistics\\
  - protocol name\\
  - protocol port number\\ //direction subs --> inet//\\
  - number of packages\\
  - volume in bytes ip total\\
  - dropped packages\\
  - dropped byte\\ //direction inet --> subs number of packages etc.//\\
