Troubleshooting Database Performance Issues with FusionReactor (View video , Show Description )Have you ever wondered if database performance issues were killing your web applications? Whether running CFML or Java apps (FR can monitor both), did you know that FusionReactor lets you view the JDBC activity for every request? You can see the SQL in queries (select, insert, update, delete, etc.) as well as stored procedure calls, and the arguments to either of those types. You can also see JDBC activity you may not code yourself, such as the SQL underlying ORM calls, or the client variable database processing in ColdFusion or Lucee.
In this webinar, veteran troubleshooter Charlie Arehart will guide you through the various aspects of how FR can watch every query, including how such monitoring is filtered by default and can be configured to suit your needs. He'll show you the various places JDBC activity is tracked in the FR web interface (including powerful aggregation across and within applications), as well as how it is tracked in Crash Protection alert emails, and how such activity is tracked in the FR logs (on an aggregate basis per request, or even logging individual slow queries). You can even optionally have FR track the query plan created by your DB server for each query!
Armed with such information, you can better understand either hangups or slowdowns that may be caused by database activity. And while FusionReactor has no insight into what's going on IN your database or database server, specifically, it can arm you with evidence of when it detects slowness, so that you can present more factual information to work with DBAs, if indeed it helps clarify that a problem is in fact in the database.

What's new in FusionReactor 7 and 7.1 (View video , Show Description )In this webinar you'll learn about what's new in FusionReactor 7 and 7.1. Did you know there were 20+ completely new core features and 100+ major improvements and bug fixes? Obviously we can't chronicle them all, but if you are either moving to the latest release of FR or have been running on it, you'll learn about many of the key benefits. Among the new features covered will be the new CPU and heap profiling, thread visualization, JMX metric monitoring, AWS cloudwatch integration, support for more frameworks, and more.
Among the enhancements we will discuss are enhanced tracking of request errors and calls to external resources, improvements to the interactive step debugger, auto detection of datasource names, and more. FusionReactor 7 also marked the production release of FusionReactor Cloud, and we will conclude with a brief introduction to that (covered already in another full webinar earlier in 2017).

More on FusionReactor Log Analysis via Excel (View video , Show Description )In this presentation, we will show you the fundamental steps of getting the logs into Excel, and then we'll go further with several specific sorts of analysis which can be done against such log data via spreadsheets, the kinds of useful troubleshooting information we can obtain this way, and we will take time especially to leverage the unique value of pivot tables. You'll see how easy it is for you to use such spreadsheet features, by demonstration of the simple (but not always obvious) steps to follow.
This is a follow-up to last month's webinar, "Making the Most of FusionReactor's Logs". In that one, we discussed the benefits of analyzing FR's logs (for post-mortem, trend, or spot troubleshooting), and we reviewed at a high level the many tools available to do such analysis. In this webinar, we will go deeper into using spreadsheet tools like Excel (though the concepts apply as well to OpenOffice Calc and Google Sheets).

Troubleshooting JVM memory problems with FusionReactor (View video , Show Description )Are you aware of all the ways that FusionReactor can help you troubleshoot memory problems? They're the bane of Java-based applications and application servers, right? Actually, sometimes what seems to be a "memory leak" actually has a root cause having nothing to do with JVM tuning or GC algorithm choices. Indeed, there are many tools and techniques that many turn to when trying to solve such problems, as well as tips and gotchas that may or may not really prove accurate or true for your own problem. There are also a fair share of (well-meaning) myths that swirl around resolving JVM memory problems.
n this webinar, veteran troubleshooter Charlie Arehart will show the ways that FusionReactor can be used to understand (and indeed prove or disprove) JVM memory problems. Is there a problem with your heap, or might you be misunderstanding something you see? If memory use truly is high, what might be the cause? Or might you have a different kind of memory problem in another JVM memory space, like the code cache, or the metaspace (in Java 8 and above, or permgen in 7 and below)? Is garbage collection happening? Is it hurting? Would forcing one help clear up a misunderstanding? FusionReactor can show all this and more as we'll see in this webinar, and soon it will help even more!

Making the Most of FusionReactor's Logs (View video , Show Description )In this webinar, veteran server troubleshooter Charlie Arehart will take you on a guided tour of the logs, with a focus on how to get to them (in the FR UI and in the file system), how to find and use the online help for the logs, and most important how to use tools to make them easier to digest. We'll start with spreadsheet tools (Excel, OpenOffice Calc) which can do a great job lining up columns, as well as offer feature to sort, filter, and of course sum (where appropriate) the data in metric columns.
Then we'll move on to the more advanced notion of pivot tables (or data pilots as their known in Calc), which can do a great job slicing/dicing the data, creating aggregate counts, and lots more. We'll wrap up with the nifty free LogParser tool from Microsoft (which lets you query logs using SQL, from the command line), as well as some other log viewing tools which at least can make it easier to view the FR logs in a nice columnar display. We'll conclude pointing out still other tools/services that focus on digesting/archiving logs of any sort, and then finally we'll discuss briefly FusionAnalytics, a sister tool to FusionReactor which provides a lot of the above in a single package, which we'll go over in more detail in a later webinar.

FusionReactor: Post-crash troubleshooting (View video , Show Description )Most people think to use FusionReactor to troubleshoot a problem WHILE it's happening (looking at slow requests and queries, etc.), but they may find that once their instance (of CF, Lucee, or a Java server) has crashed/restarted, they can't see anything in FusionReactor about what went on BEFORE that crash/restart. In this webinar, veteran troubleshooter Charlie Arehart will guide you through using aspects of FR that CAN very much be helpful to understand and even resolve the causes of such crashes, especially via the FR logs and Crash Protection alert emails.
He'll review some specific examples of common problems and how to troubleshoot them this way. He'll also briefly discuss the separate tools FusionAnalytics and FusionReactor Cloud, which each show information across restarts. Finally, he'll show how there's even value in the currently displayed FR information, at least to compare what the logs show to what's "normal" as shown now.

Setting up and Using the FusionReactor Enterprise Dashboard (View video , Show Description )For users of FusionReactor Enterprise or Ultimate (or the Trial or Developer editions), it's possible to setup an Enterprise Dashboard (ED) which can watch any number of FusionReactor instances (Enterprise/Ultimate/Trial/Dev) in a single screen (and optionally from a separate server from your monitored instances).
In this webinar, veteran troubleshooter Charlie Arehart will demonstrate first how the ED lets you watch the overall health of one or many FR instances, how you can choose to see a subset of metrics about a monitored instance, or how you can drill down into the more detailed FR UI for a given instance. We'll then discuss the implementation and configuration of the ED, including how and where it can be implemented (pros and cons of various choices), and how to add instances to the ED (whether automatically or manually), and how multiple instances can be "grouped' within the ED for still better manageability.
The FR Enterprise Dashboard also reacts to when a monitored instance becomes unresponsive, and we'll see demonstrations first of how it indicates visually the overall health of the monitored instance(s), as well as how it can be configured to send an email notification of when an instance becomes unresponsive. The ED can even be configured to restart an unresponsive instance (and the determination of when a server is deemed unresponsive is itself configurable, as we'll see).
