     +====== FastPCRF Logs ======
     +{{indexmenu_n>2}}
     +===== Tracing =====
     +The level of detail in the logs is set by the ''trace'' parameter in the **''/etc/dpi/fastpcrf.conf''** configuration file.
     +<note important>The ''trace'' parameter is ignored if the ''[[en:dpi:bras_bng:radius_integration:radius_auth_fastpcrf_setup:radius_auth_fastpcrf_setup_full|verbose]]'' parameter is set to ''1'' — this value enables trace output for **all** subsystems.\\ To configure logging for one specific or several subsystems, the ''verbose'' parameter must be set to ''0''.</note>
     +The ''trace'' parameter is a bitmask, where each bit enables detailed logging for a specific subsystem:
     +  * ''0x00000001'' — connection monitor — RADIUS connection monitor. Monitors connection activity and decides to switch to a backup RADIUS server if necessary.
     +  * ''0x00000002'' — task scheduler — internal task scheduler.
     +  * ''0x00000010'' — auth server — responsible for receiving authorization requests from fastDPI (fastDPI -> fastPCRF communication).
     +  * ''0x00000200'' — radius_client connections — detailed logging of Access-Request queries and Access-Accept/Reject responses.
     +  * ''0x00000400'' — radius_client monitor — logging of Server-Status requests checking RADIUS server liveliness and responses to them.
     +  * ''0x00001000'' — CoA server — CoA event logging.
     +  * ''0x00002000'' — CoA listener - creation of connections with CoA clients.
     +  * ''0x00004000'' — CoA processor - detailed logging of CoA requests.
     +  * ''0x00010000'' — fdpi_ctl - logging of events for sending data to fastDPI (fastPCRF -> fastDPI communication).
     +  * ''0x00020000'' — fdpi_crl FIFO - events of the message queue from fastPCRF to fastDPI. CoA requests that need to be sent to all fastDPI servers enter this queue.
     +  * ''0x00100000'' — logging of start/stop accounting sending.
     +  * ''0x00200000'' — logging of interim update accounting sending.
     +  * ''0x00400000'' — logging of receiving raw accounting data from fastDPI.
      
     +<note important>The ''trace'' parameter is hot: its value can be changed on the fly using the ''service fastpcrf reload'' command</note>
     +
     +FastPCRF logs its actions to the **''/var/log/dpi''** directory.
     +
     +Log purposes:
     +
     +===== fastpcrf_alert.log =====
     +Log of fastPCRF startup/shutdown. If any errors occurred during startup/stop, you will see them in this log.
     +
     +===== fastpcrf_ap0.log =====
     +Log of receiving authorization requests from fastDPI (fastDPI -> fastPCRF communication):
     +  * connection errors with fastDPI;
     +  * traces of authorization requests received from fastDPI;
     +  * traces of receiving accounting data from fastDPI.
     +
     +===== fastpcrf_ap1.log =====
     +CoA log:
     +  * connections with CoA clients;
     +  * receiving and processing CoA requests;
     +  * communication with DHCP and DHCPv6 servers when processing ''Framed-Pool'' and ''Framed-IPv6-Pool'' attributes.
     +
     +===== fastpcrf_ap2.log =====
     +Interaction with RADIUS authorization servers:
     +  * connection and disconnection of RADIUS servers;
     +  * Access-Request authorization queries;
     +  * Access-Accept/Reject responses.
     +
     +===== fastpcrf_ap3.log =====
     +Accounting log:
     +  * connection and disconnection of RADIUS accounting servers;
     +  * maintenance of the internal accounting database;
     +  * start/stop of subscriber accounting;
     +  * sending accounting data.
     +
     +===== fastpcrf_ap4.log =====
     +Log of fastPCRF -> fastDPI communication:
     +  * connection with fastDPI via the control port;
     +  * sending authorization results to SSG;
     +  * sending CoA requests to SSG.
     +
     +===== fastpcrf_stat.log =====
     +Internal fastPCRF statistics:
     +  * memory allocation;
     +  * number of requests sent to RADIUS and responses received;
     +  * CoA statistics;
     +  * statistics on connections with RADIUS servers and with fastDPI.
     +
     +FastPCRF periodically dumps its internal statistics into this log.
