RHDS multiple network interfaces and SNMP counters index strings limitations
Issue
How to configure SNMP monitoring of several Red Hat Directory Server (RHDS) instances on a single multi-homed platform?
The administration guide have some steps, but it shows the SNMP mibs are configured via port assignments.
This is a problem when running multiple instances using multiple network interfaces, all listening on the same TCP port number 389.
