The Net-SNMP folks have a great AgentX API I hear. I also need to write one for PostgreSQL. CC'ing various parties. With PgSQL its easy to write a POSTGRESQL-MIB -- you just transclude the pg_catalog and information_schema schemas in template1 into SNMP tables. With Xen we'd have to look at how a Net-SNMP daemon running in DOM0 could read the specs from "xm info" (/proc maybe) Sounds like a fun project. ~BAS > Do you know where one can find it ?

With PostgreSQL, a the agent can simply daemonize and talk to the
Postmaster using libpq and proper HBA. Everything in pg_catalog.* and
information_schema.* is already quantified in SQL data structures:
