Web Sites and Services MP Overview Monitor availability and performance of Web Sites and Web Services Perform HTTP requests against the monitored applications (aka synthetic transactions) Collect and alert on availability and performance metrics Build SLA reports based on collected metrics

Web Sites and Services MP Synthetic Transactions Synthetic Transaction Surrogate, fake, or test transactions created by performance management solutions and sent through the system Great for monitoring application performance from the client perspective. Perform HTTP requests against the monitored applications Rules triggered by timed-providers which in turn run a response Used in other MPs including Active Directory MP, Exchange MP

Web Sites and Services MP Architecture Console with WSS Configuration Wizard Management Server One. Point DB Server MOM Agents with WSS Client Component Web Sites & Services

Web Sites and Services MP Monitoring a web page or individual URL Web pages consist of base page and content Images, Scripts, Style sheets, Frames, Links Implicit content monitoring Supply base page URL and choose type of content to be monitored Pros: no need to update the monitor when the Web page content changes Explicit content monitoring Supply base page and content URLs Pros: monitoring criteria can be set for each URL

Web Sites and Services MP Monitoring a web site A Web site is collection of Web pages Each Web page can be monitored with implicit or explicit inclusion of content Manually create HTTP requests is easier for implicit inclusion of content Capture Web site navigation (via Internet Explorer) is easier for explicit inclusion of content

Web Sites and Services MP Monitoring a web application A Web application transaction is an ordered sequence of Web pages Use Capture Web site navigation for easy authoring Resulting Request Sequence monitors Web pages using explicit inclusion of content Can be “converted” to implicit inclusion Mark each Web page as “critical” request Prevent expired certificates by monitoring days to HTTPS certificate expiration date

IIS and WSS MP working together IIS Management Pack Infrastructure Monitoring Monitors server fundamentals: services, sites, app pools Access to IIS generated performance data Can not always tells between inactive and unreachable websites Some errors may be false alarms 404 s from stale links / bookmarks 500 s from malformed requests Monitors all IIS Services and Servers: SMTP / FTP / NTTP not just Web Services / Sites

IIS and WSS MP working together WSS Management Pack Monitors health of the actual Web application by exercising its functionality Overall response time is extrapolated from data points at each monitoring interval. Offers understanding of client experience Can monitor health even when there is no activity No false alarms due to updated content Can be deployed separately to monitored server Able to monitor non-IIS servers With the IIS MP, gives a complete web monitoring solution

Summary MOM 2005 provides a complete monitoring and alerting solution for Windows infrastructure IIS Management pack provides IIS perspective WSS Management pack provides client perspective Together, provide a complete web monitoring solution Is MOM 2005 all you need?
