Hi Mark/Mitch/Group..
I have read the past couple of posts from you and Mitch regarding MIBS
for Ex2K.  While Ex2K's support for SNMP is admittedly underdocumented
(even the WMI perfmon stuff Mitch was referring to), there is SOME
relief for you!

"Out of the Box", Ex2K supports SNMP queries through the SMTP.MIB
(attached for you to reveiew), as it can now use the Simple Mail
Transport Protocol service that installs as part of IIS.

(Be sure to load W2K SP3 as there are some SMTP relaying bugs fixed)

The key is whether or not the extension DLL (SMTPMIB.DLL) is loaded.  In
many cases, the file is there
(%SystemRoot%\System32\inetsrv\smtpmib.dll), but the SNMP registry hive
has not been updated to load it on startup with the SNMP service.

I an also quite sure that there is some support for the Mail and
Directory Management Management Information Base (MADMAN MIB)is also
supported.  Check out RFC-1566 (also attached).  It never hurts to load
the MIB and try your query.

If you are looking to monitor MORE than what you see there, then why not
take a look at my little SNMP agent called SNMP4W2K-PLUS.  It includes
SMTP support, and will modify the registry to load the SMTPMIB.DLL if
you tell it to, adds NNTP (news) support as well (through NNTP.MIB and
NNTPMIB.DLL) and adds SNMP support for Ex2K performance counter objects,
a list of which can be viewed in the PERFMIB.INI file here (bottom of
file, between 70 and 81).


BTW, here are a couple of good articles about Ex2K monitoring...



Best regards!

I spend some time looking at this. All the reading I did basically
points to Exchange 2000 not having a MIB for this. The MIB you are using
looks like Exchange 5.5. I used getif and browsed to that MIB on my
Exchange 2000 server. When I poll it there is no data. According to MS
you need to use a WMI performance monitor to look at these stats and
Exchange 2000 doesn't use snmp.

Thanks again Microsoft!

Let me know if you come up with anything different.
