1. Would say CDR_ODBC has a greater chance than CDR_CUSTOM (if I may call them both as such) to become a bottleneck under pressure ?
2. I didn't know about batch mode existence. Thanks for presenting it. In such batch mode, where are stored CDRs before being written to files or database ? Does it also apply to data later found in cdr-scv/Master.csv file ? 2018-02-22 18:14 GMT+01:00 Richard Mudgett <[email protected]>: > > > On Thu, Feb 22, 2018 at 5:23 AM, Olivier <[email protected]> wrote: > >> Hello, >> >> I'm load testing a new Asterisk 13 system (Debian Stretch, packaged >> asterisk). >> One system writes CDR though an ODBC connection to a local Postgres >> database over the LAN. >> >> >> When sending 50 new calls per second with SIPp, I'm seeing one system >> outputs : >> taskprocessor.c: The 'subm:cdr_engine-00000003' task processor queue >> reached 5000 scheduled tasks again. >> >> This [1] thread mentions such limit. >> >> I was thinking of simply writing CDR entries to a local file before >> centralizing them into my database. >> >> What would you suggest on this topic ? >> > > You should get better CDR performance enabling batch mode which is > disabled by default for legacy reasons. > > The CDR code processes all call events in one thread to create CDRs.
