We want to monitor our email traffic using perfmon. Which stat do we monitor? We see loads Emailsp/min and smtp use etc. but we are not sure which one will give us a definate figure.

Hi, Would you please let me know which SMTP information you would like to monitor? The total message sent size, the total number of messages sent and received or others? Regarding the Exchange performance, I suggest you read following information TechNet Support WebCast: Performance baselines and troubleshooting analysis in Microsoft Exchange Server 2003: http://support.microsoft.com/kb/891814/en-us Troubleshooting Microsoft Exchange Server Performance http://technet.microsoft.com/en-us/library/aa997270.aspx Mike

Hello,Addition to Mikes response, you can use MOM/SCOM to monitor your Exchange performance automatically or you can even use manual method for monitoring and alerting on specificproblem when queues get build-up http://searchexchange.techtarget.com/tip/0,,sid43_gci1306015,00.html Amit Tank | MVP - Exchange | MCITP:EMA MCSA:M | http://ExchangeShare.WordPress.com

basically how many mails are recieved and sent over a specified time period. at the moment we use recieved/min and sent/min but the figures we get from there do not match our pure message server.

Hi, I think that you can use following counters to monitor the message received and sent: Performance Object: SMTP Server Counters: Messages Received Total Messages Received/sec Messages Sent Total Messages Sent/sec Mike
