7.6. Additional Sources of Diagnostics Information

The following additional sources of management data may be also used:

When trying to understand some unexpected network or SBC behaviour the following facilities can be also helpful:

  • Audio can be recorded as described in Section Audio Recording.
  • CDRs, as described in Section Call Data Records (CDRs), include useful information.
  • The ABC SBC can be configured to send notification by email if some serious error such as exhausted disk space occurs. Configure the recepient email address under “Config‣Global Config‣Monitoring‣Email for sending alerts”. Configure SMTP server to which the emails will be passed under “Config‣Global Config‣Monitoring‣Mailserver for sending alerts” if you need to use external mail server, or use default “localhost” to send the alert emails directly from the ABC SBC server. Configure various thresholds for alerts based on high system load, memory used, cpu waiting percentage and disk usage percentage under “Config‣Global Config‣Monitoring”.
  • There is a hidden webpage that includes a snapshot of all important system information. It can be found in the web interface under the path /frafos-sbc/sysinfo.php.cgi . Always provide this webpage when communicating with customer support. The webpage can take several minutes to appear because it gathers extensive amount of system information.
  • There is a hidden webpage that creates a compressed tarball file with a snapshot of all important system information, dump of ABC SBC database configuration tables and latest coredump file (if existing) and starts download of the file. It can be found in the web interface under the following path: /frafos-sbc/sysdata.php.cgi Please have this snapshots ready when approaching customer support. This diagnostic tarball is created also automatically when any new coredump file is detected. There is also another hidden webpage under the following path: /frafos-sbc/sysdata-latest.php.cgi This link initiates download of the latest already created diagnostic tarball file, without creating new one. The diagnostic files are placed in /data/sbc-sysdata dir by default.
