6 Many different tools available Some free, some commercial Some work with CF, some are not specific Among them Performance analysis and monitoring tools Load testing tools Debugging tools (server and client) Log analysis tools Other tools Check out especially my CF411.com 6

8 CFStat Command line tool, found in [cf]\bin\ Not available in multiserver/multi-instance mode CF Performance Monitor stats Windows tool, but with CF-specific info Note: Previous two be enabled in CF Admin (debugging page) GetMetricData CFML function Options include perf_monitor, simple_load 8

11 FusionReactor Also works with OpenBD, Railo SeeFusion These both work with CF 6, 7, and 8 Both have free trials 11

12 All 3 CF monitors really open the black box of CF See all currently running requests Can terminate long-running ones View past long-running requests (while server is up) See details of each queries executed in request See stack trace to view line of code being executed CF8 monitor can view all sessions, applications, and more FR and CF8 monitor can be configured to send notifications of problem states Requests taking too long, too little memory, etc. FusionReactor also Writes out substantial log files Can run scripts when monitored server stops/starts And much more 12

13 New tool coming from Intergral Makers of FusionReactor Powerful tool that solves problem of server analysis over CF restarts Saves you the hassle of reading log files Does powerful analysis across many logs CF FusionReactor Others will be added Designed to permit you to point to new logs 13

14 Windows Task Manager SysInternals ProcessExplorer Powerful replacement for Task Manager Windows Performance Monitor SysInternals Process Monitor Combines former Filemon, Regmon tools 14

15 Consider tools available for databases Free SQL Server Profiler/Trace Spotlight on MySQL Commercial Spotlight on SQL Server (others for DB2, Oracle, etc.) Confio Ignite (for multiple DBMSs) MonYog (for MySQL) Others exist as well, of course 15

19 [cf]\runtime\logs Or in Multiserver (Multi-instance) mode, [jrun4]\logs -event, -err, -out logs Note Can modify CF so that different files hold different log info levels (info, debug, metrics, etc.) See (and others) for how to edit [cf]\runtime\servers\coldfusion\server- INF\jrun.xml 19

20 Debugging & Logging>Logging Settings Log slow pages taking longer than X seconds Enable logging for scheduled tasks Server Settings>Mail>Mail Logging Settings Error Log Severity Log all mail messages sent by ColdFusion Datasource Advanced Settings Log Activity Writes substantial amount of data about connection to database, including all data returned Note: need to name directory AND filename 20

21 Web Server Logs Database server logs Windows Event Viewer (interface to logged data) Windows Performance Monitor and logging options Equivalents on other OS platforms FusionReactor logs Verbose GC logging 21

22 Universal Viewer (ATViewer) Log Parser (free, from Microsoft) Sawmill Universal Log File Analysis & Reporting (not free) Many web server log analysis tools, of course Google Analytics AWStats (awstats.sourceforge.net), etc. None of these are CF-specific, of course 22
