Overview
We can enable Detailed logging in VEGA per module basis in order to speed up debugging.
...
Enable default logs as mentioned in Vega Troubleshooting-Information page. This will help to get top level module information which is having an issue and then we can enable detail logging for that module.
Precaution
Please make sure detailed loggings are not enabled during traffic (more than 0.5 CPS or so) where enabling detail logging can affect VEGA performance.
...
Please DO NOT enable details logging in a production environment where traffic keeps going constantly.
Logging Modules
“debug help” in Vega CLI will show you the list of all modules and their debugging level as defined in VEGA CLI Help section.
Details of each module are defined in the following subsections.
SIP Module
This module is responsible for complete SIP call processing.
...
debug disable _sip ietf123456789 (disable complete logging)
ISDN Module
This module is responsible for all ISDN Call processing.
...
debug disable _isdn ietf123456789 (disable complete logging)
POTS Module
This module is responsible for all POTS related call control and supplementary services processing.
...
debug enable _default 4 (for pots supplementary services logging)
CAS Module
This module is responsible for MFC-R2 protocol stack.
...
NOTE: Also refers to Vega R2 Debugging
DSP Module
Whenever we see some issues related to DSP module then we could enable DSP module logging.
...
debug disable _dsp ietf123456789 (disable complete logging)
LANAPI Module
Whenever we see some issues related to LAN/Networking/DHCP/DNS etc, we could enable this module logging to troubleshoot further.
...
debug disable _lanapi ietf123456789 (disable complete logging)
ROUTER Module
This module is responsible for relaying the messages between different modules like passing a message from SIP to ISDN will go via this module.
...
debug disable _router ietf123456789 (disable complete logging)
Ethernet Module
This is to look for Ethernet/NIC level issues.
...
debug disable _ethernet ietf123456789 (disable complete logging)
TN Module
This module is responsible for low-level ISDN protocol stack.
...
Note: Generally we like to enable ISDN module logging as well in order to capture complete ISDN processing starting from protocol to call control.
MG/MC/MT Module
These modules are responsible for Media/DSP and interface between DSP and SIP module. So whenever we like to debug media related issues where we don't see anything wrong in SIP and in DSP then we could enable this logging as well depends on issue scenario.
