High Availability:Software:CDR
From TBwiki
The CDRs are another critical section of a system. Toolpack can generate 2 types of CDRs: RADIUS and text base.
High Availability
Radius
As of now, Toolpack can send CDR to only 1 RADIUS server at a time. Therefore it is not recommended for a high availability system.
Text Base
Only the active instance of the gateway application will write the CDR information locally on the host. When there is a switchover the newly active gateway application will write the CDR locally on its host. To gathered all the CDR information, it is important to read the CDR from both hosts.
Note: CDR information may be missed during a switchover.
Security measure: Customers should copy the CDR from the Toolpack host on a regular basis to avoid lost of data in the event of a hard drive crash.
