Thanks,
I already looked through that information. I can not see any snmp way of asking for # of current connections.
That piece of info would work great to monitor for floods or some other problem.
The performance counters are stored somewhere, as the admin console displays them. I just need to track where.
Dennis,
Assuming you've already seen this HowTo:
http://directory.fedoraproject.org/wiki/Howto:SNMPMonitoring
I was looking for the same thing some time ago, and eventually decided that the objects offered via SNMP weren't cutting it, and so switched to fetching that info directly out of the monitor branch using ldapsearch, which provides, among other interesting bits, currentconnections, totalconnections and connectionpeak, e.g.:
me@somehost% ldapsearch -H ldap://my.ldap.host -b 'cn=monitor' -v -x -LLL cn='monitor' ldap_initialize( ldap://my.ldap.host ) filter: cn=monitor requesting: ALL dn: cn=monitor objectClass: top objectClass: extensibleObject cn: monitor connectionpeak: 1260 version: Sun-Java(tm)-System-Directory/6.2_GP_6597523 B2007.264.1019 threads: 30 currentconnections: 199 totalconnections: 454235 dtablesize: 65536 readwaiters: 0 opsinitiated: 5735651 opscompleted: 5735650 request-que-backlog: 0 entriessent: 1359462 bytessent: 1148150533 cache-avail-bytes: 7282450432 heapmaxhighhits: 0 heapmaxlowhits: 0 currenttime: 20080523175805Z starttime: 20080521135633Z nbackends: 12 currentpsearches: 0
...which is basically what the helper script mentioned on that page is doing. As you can see the example above is against Sun JDS 6, but IIRC, it works the same on FDS (sorry, don't have an instance available at the moment for testing.)
HTH,

I've got a question I've been trying to hunt down.
Is there any way for snmp to monitor connections to the directory server?
I see there are entries for snmp to see things like # of entries added since restart.. However are there any good resource summaries I can monitor? Ie the Performance counters in the admin console?
This might help - *http://tinyurl.com/667xpc*
