[SR-Users] logging error events to database

Not directly from Kamailio, unless you want to "log" manually using
sql_query().
Commonplace approaches for this:
1) Forward Kamailio syslog data to a syslog-ng server - i.e. in your
local /etc/rsyslog.conf or whatever:
local0.error @remote.server:514
syslog-ng supports PostgreSQL and other storage destinations:
https://wiki.archlinux.org/index.php/syslog-ng#PostgreSQL_Destination
And it can filter and parse entries based on regular expressions to make
what you store more selective.
However, beware of the uncertain performance characteristics of this
setup under heavy loads, and also the poor suitability of RDBMs to
short-lived data sets that constantly turn over. Lessons learned the
hard way.
2) The Elasticsearch way -- which originally required Elasticsearch +
Logstash, but now apparently can work through syslog-ng directly:
https://www.syslog-ng.com/community/b/blog/posts/logging-to-elasticsearch-made-simple-with-syslog-ng
Of course, you can still go the traditional Logstash route.
I haven't personally used Elasticsearch, but it sounds like the better
way to go than a traditional RDBM if you're dealing with large volumes
of syslog data that are rotated out frequently.
On the other hand, if you're only looking to log occasional critical
errors, not "everything", then just about any approach will work fine.
