I'll be speaking at next week's dev.Objective() Conference, in Minneapolis (June 15-17). The conference is always a great time, in a great location, with great people, and lots of useful information shared, and I appreciate the conference team selecting me again to be a speaker. If you'll be attending, I hope to see you.

See you at dev.Objective() in mid-May (I'll be speaking)

Just wanted to share word (sorry it took so long) that I'd been selected as a speaker at the upcoming dev.Objective() conference, in Minneapolis in Mid-May. Hope to see lots of my fellow CFers there, and of course new folks who were not CFers.

While the conference name has changed (from cf.Objective()), there are still plenty of CF-oriented topics, and of course as nearly everyone would point out, it's good for everyone to expand their reach and focus.

To that end, I'll be doing a topic a bit different than my normal focus of CF server troubleshooting. Instead, recognizing that there will be folks there who either use other servers, or develop web apps or mobile apps, I'll do a bit of a "soft" topic on how to troubleshoot performance problems more generically, in:

Hey, my web app's slow. Where's the problem?

Looking to buy ColdFusion? Get it at a discount from the FR folks, and an additional discount off FR

Note: This blog post is from 2015. Some content may be outdated--though not necessarily. Same with links and subsequent comments from myself or others. Corrections are welcome, in the comments. And I may revise the content as necessary.
If you're in the market to buy ColdFusion, whether a full license or an upgrade from the prior release, you can get a discount off the retail (Adobe) price by buying from www.buy-adobe-software.com, which is a site by the fine folks who make FusionReactor, who are an official Adobe reseller. Why pay full price for CF if you can save, up to 10% currently?

Even better, for a limited time (as of this writing in Mar 2015), folks making such a purchase of CF there will get 20% off a purchase of FusionReactor Standard or Enterprise Subscription, if purchased at the same time. Such offers come and go, if you may be reading this later.

So if you're looking to buy CF, you can save money on CF AND get a great monitoring solution for CF. I work with it daily, using it on my sites and nearly always recommending it as the best tool for solving CF problems. (It also works with Lucee/Railo, and BlueDragon Server JX, as well as Tomcat, JBoss, Jetty, GlassFish, and indeed any Java application.)

See my FusionReactor category of blog posts for more I've shared on FR over the years.

FusionReactor updated today: some general info related to getting/applying FR updates

Note: This blog post is from 2015. Some content may be outdated--though not necessarily. Same with links and subsequent comments from myself or others. Corrections are welcome, in the comments. And I may revise the content as necessary.
How to update FusionReactorFusionReactor users will want to know that there was a new update released today, 5.2.6. The update is free for those on 5.2.x releases as well as those with maintenance agreements. And you can just download the installer and run it to update your current version (even back to FR 5.0, if you've not updated FR 5 since you first installed it).

But more than that basic info, I'd like in this post to take advantage of the chance to share a few things related to the topic of upgrading FusionReactor, including some common questions I often am asked as I assist people in using it:

  • Where do I get the update?
  • How do I find out what's new in the update?
  • Should I hesitate about applying the very latest FR update as soon as it comes out?
  • How would you I know there WAS an update to FR available?
  • Do I just need to run the full installer or can I update just one file perhaps?
  • Do I need to restart CF (or Railo/Lucee/Tomcat, etc.) for the update to take effect?
  • Can I update FRAM and choose NOT to update my monitored CF/Railo/Lucee/Tomcat/etc instance?
  • Why do you keep referring to "CF/Railo/Lucee/Tomcat/etc"? I thought FR was a CF monitor tool?
  • What if I'm on an FR version older than 5.0?

For these and more, read on.

My New Youtube Video on the Why and How of Using FR Stack Traces for ColdFusion Troubleshooting

Note: This blog post is from 2014. Some content may be outdated--though not necessarily. Same with links and subsequent comments from myself or others. Corrections are welcome, in the comments. And I may revise the content as necessary.
As many of my readers know, I'm a big fan of the FusionReactor server monitor for ColdFusion (and Railo, BlueDragon, Tomcat, and indeed any Java server). I help people use it every day (just like I also help people leverage other CF monitors like the CF Enterprise Server Monitor and SeeFusion).

One of the most important features is the stack tracing feature, used to understand what's holding up a long-running request.

My presentations at ColdFusion Summit, CFCamp, etc.

Note: This blog post is from 2014. Some content may be outdated--though not necessarily. Same with links and subsequent comments from myself or others. Corrections are welcome, in the comments. And I may revise the content as necessary.
I wanted to share word here of the presentations I'll be offering at the upcoming Adobe ColdFusion Summit 2014 in Vegas on Oct 16-17, as well as CFCamp 2014 in Munich on Oct 20-21.

Also, sorry for the long delay in blogging. Just been so busy doing my CF server troubleshooting consulting.

As for my sessions at CFSummit (next week), I'll be doing the following (and you can follow the links to learn more about the talks, their dates and times, etc.):

At CFCamp, the following week, I'll be offering:

I had also presented the Hidden Gems talk at NCDevCon 2014.

These are all great conferences, and, in addition to cf.Objective 2014 (where I spoke also, on different topics), they are each great ways to keep up on what's going on in the world of ColdFusion and related technologies.

Finally, if someday you're visiting this blog entry and find that one of the conference links no longer work, you can find my own link to all my presentations, at all conferences the past 15+ years (as well as to any recordings made available) at my presentations page.

Come say hello if you're at any of these events.

CF911: High CPU in ColdFusion? Some common but perhaps unexpected causes

Note: This blog post is from 2014. Some content may be outdated--though not necessarily. Same with links and subsequent comments from myself or others. Corrections are welcome, in the comments. And I may revise the content as necessary.
I often help people who are reporting that CF is "running hot on the CPU", maybe reaching 80 or even 100% of the CPU, whether in spikes or for extended periods. What might you propose people look at, when you've heard that? I've heard all kinds of things over the years, often focused on coding, or perhaps jvm tuning.

But as is often the case in a lot of the CF server troubleshooting consulting I do, I find the causes to be far less often what most people seem to suspect. So what would I look for when someone reported high CPU in ColdFusion (or Railo)? Read on.

Tracking ColdFusion sessions within FusionReactor, by way of FREC logging

Note: This blog post is from 2013. Some content may be outdated--though not necessarily. Same with links and subsequent comments from myself or others. Corrections are welcome, in the comments. And I may revise the content as necessary.
Someone asked on the FusionReactor mailing list (a Google Group) whether FusionReactor tracked CF sessions. I started to write a reply, with the good news/bad news in answer to that, and as sometimes happens, it became long enough that I thought it might be better suited as a blog entry that I could point to from the list instead, and which may also help those not on the list (which is a great resource, as a low-volume list with a high signal to noise ratio.)

Anyway, here is the answer I wanted to offer to that question...

Recording of my Adobe eseminar session, "Monitoring ColdFusion with FusionReactor"

Note: This blog post is from 2012. Some content may be outdated--though not necessarily. Same with links and subsequent comments from myself or others. Corrections are welcome, in the comments. And I may revise the content as necessary.
After my barrage Friday of four entries on the CF Server Monitor, here's something instead on FusionReactor. Some may know that last week I did a talk on the Adobe ColdFusion eseminar series, "Monitoring ColdFusion with FusionReactor". I got word today that the recording link has been posted.

You can find the recording here. Note that you need to login with an Adobe ID, just like when you download Adobe software or participate in their forums. (I have no control over that.)

Since that link just goes right to the recording, here is the description I'd used for the session, to help decide if the recording may interest you. BTW, I clarify on the session that FR is useful for more than just ColdFusion, in that FusionReactor can be used for Railo, BlueDragon, and OpenBlueDragon, as well as in fact any Java server (Tomcat, JBoss, Jetty, Glassfish, Websphere, etc.), and the session applies just as well to folks using those.

CF911: Want to monitor ColdFusion "out of process" (from outside the instance itself)? Many ways.

Note: This blog post is from 2012. Some content may be outdated--though not necessarily. Same with links and subsequent comments from myself or others. Corrections are welcome, in the comments. And I may revise the content as necessary.
I just blogged about how the hidden gem "enable monitoring server" option in CF 9.0.1 does NOT cause the CF Server Monitor to somehow magically run "out of process". See more on that.

Yet people will reasonably want to be able to have some mechanism that "watches" CF "from the outside", to know when it's gone down. How can you do that? That's what I'll point out in this entry.

And beyond talking about what goes along with the CF Enterprise Server Monitor, I'll also point out options for those who are NOT running CF 8, 9, or 10 Enterprise and therefore do not have the Enterprise Server Monitor. This also includes those CF 6 or 7. There are solutions for you, and also for those running Railo, BD, or indeed any Java server. More on all that in a moment.

This is part 4 of an unexpected series of entries today on the CF Enterprise Server Monitor. :-) I got on a roll, and each seemed deserving of its own topic. See the "Related Blog Entries" below this entry for links to those.

What the CF Server Monitor is, and is not
