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

...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.)

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*
