http://www.msexchange.org -------------------------------------------------------Thanks James. When using exmon, what fields would show IO usage? There is obviously bytes in and bytes out but what about packets or operations? Our disk is being slammed by IO and I sometimes wonder is it really the amount of data being transferred or could it be lots of searches, indexing, etc where people aren't necessarily transferring large attachments but are just doing a lot of manipulation of e-mail. For example, which would make more IO - copying one large file from one disk to another or thousands of small files equal to the large file. Users on the top of the list in bytes in and bytes out are always changing. I noticed that users in the top of the list of packets and operations are usually the same bunch. Thanks again. ___________________________ Nathan Nimori Systems Engineer East Side Union High School District -----Original Message----- From: exchangelist-bounce@xxxxxxxxxxxxx [mailto:exchangelist-bounce@xxxxxxxxxxxxx] On Behalf Of James Chong Sent: Wednesday, May 28, 2008 11:34 AM To: exchangelist@xxxxxxxxxxxxx Subject: [ExchangeList] Re: Messages stuck in "local delivery" queue http://www.msexchange.org -------------------------------------------------------Could be several reasons 1. DSACCESS related issues. Turn up diagnostic logging. 2. Sites and services are misconfigured and Exchange is using a remote GC for lookups 3. You are incurring additional IO for some reason. See if there is some process running; some large mail sent etc. Run perform and check your physical disk avg disk sec reads and avg disk sec write. If you're over 50ms sustained you need to investigate. Also can look into using exmon to see if a particular user is incurring the additional IO 4. Turn up diagnostic logging msexchangetransport 5.
