    -====== FastDPI monitoring and logs ====== 
    -{{indexmenu_n>14}} 
    -System logs are presented as text files that are located in the /var/log/dpi directory for DPI and PCRF modules. 
    -Types of messages in the log: 
    -  - [CRITICAL] - critical error, system operation is impossible without troubleshooting 
    -  - [WARNING] - warning, the system does not stop, but it is worth eliminating this malfunction 
    -  - [TRACE] - messages when the diagnostic trace mode is enabled 
    -  - [INFO] - notification of system actions 
    -  - [ERROR] - error when connecting services and policies, incorrect configuration 
    - 
    -The FastDPI process by default logs all system actions to the following debug and statistics log files: 
    -  - [[en:dpi:dpi_components:platform:mon_stat:slave_log:start|/var/log/dpi/fastdpi_slave*.log]] - a log of traffic processing processes 
    -  - [[en:dpi:dpi_components:platform:mon_stat:stat_log:start| /var/log/dpi/fastdpi_stat.log]] - traffic processing statistics log 
    -  - [[en:dpi:dpi_components:platform:mon_stat:alert_log:start| /var/log/dpi/fastdpi_alert.log]] - common fastDPI functions log 
    - 
    -Note: For each handler, its own fastdpi_slave log is created, other log files are created in a single copy.

    -We offer you the following set of parameters that can be received from the VAS Experts DPI: 
    -  - fastDPI process errors from the ///var/log/dpi/fastdpi_alert.log// log file 
    -  - system log errors from ///var/log/messages// 
    -  - drops within the DNA interfaces 
    -  - traffic volumes on the interfaces 
    -  - availability of management interfaces  
    -  - the number of processed requests over HTTP and HTTPS 
    -  - the number of blocked resources over HTTP, HTTPS, IP 
    -  - the number of PPPoE sessions 
    - 
    - 
    -You can use zabbix agent for monitoring. Installation Description: 
    - 
    -1. Install zabbix agent on the server: 
    -  rpm -ivh http://repo.zabbix.com/zabbix/2.4/rhel/6/x86_64/zabbix-release-2.4-1.el6.noarch.rpm 
    -  yum install zabbix-agent 
    - 
    -2. Update SELinux policy 
    - 
    -''yum update selinux-policy'' 
    - 
    -3. Put {{ :dpi:dpi_components:platform:mon_stat:skat_userparams.zip |skat_userparams.conf}} to the /etc/zabbix/zabbix_agent.d/ directory and [[http://vasexperts.ru/upload/zabbix_agentd.conf|zabbix_agentd.conf]] to the /etc/zabbix/  
    - 
    -4. Edit /etc/zabbix/zabbix_agentd.conf file: 
    -  Server=%zabbix server address% 
    -  ServerActive=%zabbix server address% 
    -  Hostname=%server hostname% 
    -   
    -  
    -5. Change the context of the /var/log/dpi/fastdpi_stat.log file: 
    -  chcon unconfined_u:object_r:zabbix_log_t:s0 /var/log/dpi/fastdpi_stat.log 
    -  
    -6. Add to the /etc/sysconfig/iptables the following rule before -A INPUT -j REJECT:\\ 
    - -A INPUT -p tcp --dport 10050 -j ACCEPT 
    - 
    -7. Reload iptables rules: 
    -  service iptables reload 
    -  
    -8. Add zabbix agent to start on boot and start it: 
    -  chkconfig zabbix-agent on 
    -  service zabbix-agent start 
    - 
    -9. Import prepared template in Zabbix 
    -  * For version 4.2 (new) - {{ :dpi:dpi_components:platform:mon_stat:zbx_export_templates_4.2.zip |zbx_template_dpi_4.2.xml}} 
    -  * For version 3.4 (new) - [[http://vasexperts.ru/upload/zbx_template_dpi_3.4.xml|zbx_template_dpi_3.4.xml]] 
    -  * For version 2.4 (old) - [[http://vasexperts.ru/upload/zbx_template_dpi.xml|zbx_template_dpi.xml]] 
    -In the Zabbix server control panel add a new host, bind this template. 
    - 
    -10. Disable requests for network interfaces that are not used in dpi by clicking on __enabled__ on the right in the zabbix GUI\\
