An overview of the nifty new Performance Monitoring Toolset (View video , Show Description )The objective of this session is to introduce the powerful Performance Monitoring Toolset in ColdFusion 2018, available across both Standard and Enterprise editions. Get a good understanding of all the capabilities of this toolset. It is the only tool that you need to take care all your needs around performance and stability. The toolset takes care of end-to-end performance management right from connector, application, individual lines of code, database, incoming/outgoing services, system metrics, memory management to JVM metrics. Gain insight on why this a better tool than anything you currently have or plan to have.

Troubleshooting with FusionReactor, part 4: Post-crash Troubleshooting (View video , Show Description )In the previous sessions of this series we have talked about aspect of using FusionReactor which were focused on what it could tell you while problems were happening or starting to happen. But what if your monitored instance or server has crashed/restarted?
FusionReactor tracks up to 1 week's worth of information in the core metric graphs if the server crashed or restarts, this information is no longer available (as it's stored in memory). But FR still has the information in the logs and it's still available in the Archive metrics.
In this final session introducing troubleshooting, we will focus on the aspects of FusionReactor which can be used AFTER a crash/restart of your monitored instance. In addition to two features which have long existed in FR (alerts and logs), we will especially focus on two newer features that can dramatically ease the process of post-crash troubleshooting:
- Archived metrics
- Alerts and logs
- FR cloud: alerts and profiles

Hidden Gems in CF2018 (View video , Show Description )It's that time again: another new version of CF has come out (CF2018), and it's time for veteran CF troubleshooter and presenter Charlie Arehart to continue his tradition of identifying "hidden gems" in the new release, as he's been doing since CF4. Sure, most people can name a few of the big, new features in each release, while others will lament "there's not much new", when in fact there is! Just as in every release of CF, there are always lots of things that go unheralded and which may be just what you've been waiting for or that may delight you, whether solving a long-standing problem for you or providing a new technique, and whether related to coding, troubleshooting, administration, enterprise integration, and more. Charlie will also help identify edition differences, pricing, migration issues, etc., and as always where to find out more.

Troubleshooting with FR, part 3: When requests are slow for less obvious reasons (View video , Show Description )In the previous session of this series, we looked at the features of FusionReactor that generally make it easy to see why a request or transaction is slow, but we acknowledged that sometimes those features don't identify the reason.
In this session we will look at a few of the features of FusionReactor that can be used to understand some less obvious reasons for slowness:
- Stack tracing requests
- Profiling requests
- CPU sampler
- Memory profiler
As useful as these features can be, they do all require that FR be running at the time of the hangup. What can you do when you are not able to get to FR during a hangup? Or if you are looking at it after a restart? We will cover that in the final part of this series.

Troubleshooting with FR, part 2: Why are requests/transactions running slowly? (View video , Show Description )In the previous session of this series, we took a broad view at how FusionReactor can help you understanding what is or has been going on recently in your server/instance, especially in terms of request or transaction processing.
In this session, we will delve into using aspects of FusionReactor to help understand WHY requests or transactions are running slowly. There are some aspects which stand out quite clearly to explain a slow request, if you know where to look. As such, we will cover FR features like:
- Request details
- JDBC processing within requests
- Other monitored relations/transaction types within requests
- JDBC history over all requests and applications (recent, slow, longest, and errors)
That said, some problems will remain elusive, because they have to do with a request doing something that is not so clearly identified with these features. In part 3, we will move on to using features of FR that can be used in such cases.

Troubleshooting with FR, part 1: What has just happened on my server? (View video , Show Description )In this session, the first of 4 parts, we will focus on using the key aspects of FR related to finding what is or had been going on recently in a given server/instance. And whereas some folks tend to presume that problems are due to resource issues like high use of memory or CPU constraints, often it's more important to step back first and look at the overall state of request and transaction processing, which may give real insight into the nature of problems (or indeed to confirm where there IS a problem, even when users or other monitors are reporting problems).
As such, this session will focus on making the most of these key features in FusionReactor:
- Web Metrics
- Request history (recent, slow, and longest)
- Requests error history
- CPU, memory and garbage collection information
There can be many explanations for WHY requests are slow or WHY resource usage is high. We will delve into additional features to better understand that in later parts of the series. In this first session, the goal is to get a clear understanding of the overall nature of problems, before diving into their causes.

Making your applications fast and furious with the new Performance Monitoring Toolset in CF 2018! (View video , no description * )

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).
