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).
We’ll quickly reprise 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.

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.
In 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!
In past webinars we have mentioned in passing, at various levels of detail, the availability, power, and value of FusionReactor’s many logs. While those stressed their value (whether for post-crash troubleshooting, or for observing trends, and more), they could only barely mention the tools available to help you make the most of them. 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.
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.
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).
Join us for Troubleshooting and Identifying Issues using FusionReactor 6. FusionReactor is an invaluable asset to have when trying to resolve application issues. Join us as we explore how you can find and fix you application issues with FusionReactor
Join us as we explore how to use FusionReactor Ultimate to identify and fix application issues that you would not usually be able to find an application performance monitor. Without hours or even days of work going through logs. This webinar is recommended for users of all abilities and is a perfect introduction or refresh on how to use FusionReactor to fix your application issues.
FusionReactor CLOUD moves FusionReactor from being an on-premise monitor into a Hybrid monitoring solution – extending FR’s feature set to enhance the monitoring, historic data analysis and alerting capability to new levels. Join us to learn what FusionReactor CLOUD has to offer, how it’s positioned within the Fusion product portfolio (compared to FusionReactor and FusionAnalytics) and gain an insight into the future product roadmap.
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…
So you have installed FusionReactor now what …? In this webinar we will be showing you how to get FusionReactor configured and ready for action. We will be covering the more advanced settings and features in FusionReactor. Along with showing you how to you can get to the root of the problem as fast as possible to resolve your Java application issues.
