Deploying APM in the Enterprise. In the last installment we covered how you find, test, and justify purchasing an APM solution. This blog will focus on what to do after you’ve made a purchase and started down the path of deploying your coveted APM tool (ahem, ahem, AppDynamics, ahem). Just clearing my throat, let’s jump right in…
Welcome to Part 4 of my series It’s time for a celebration, time to break out the champagne, time to spike the football and do your end zone dance (easy there Michael Jackson, don’t hurt yourself). All of the hours you spent turning data into meaningful information, dealing with software vendors, writing requirements, testing solutions, documenting your findings, writing business justifications, and generally bending over backwards to ensure that no objection would stand in your way has culminated in management approving your purchase of APM software. Now the real work begins…
The 7 Ps
A co-worker of mine shared some words of wisdom with me a long time ago which have served me well over the years. It’s a little saying called the 7 P’s and goes something like this… Piss Poor Planning Promotes Piss Poor Performance. Deploying and using APM software is not a time for spontaneity or just winging it. If you want to make mistakes and derive little value from the investment you just put your reputation behind then by all mean just jump in with little or no planning. If you want to be a rockstar you need a solid plan for deploying, configuring, verifying, operationalizing, using, and evangelizing your APM tool (ahem, ahem, AppDynamics, ahem). Just clearing my throat again, I think there’s a bug going around ;-P
This blog post is a great general outline for planning your implementation. Everything covered in this post should be part of your planning process and should be considered the bare minimum for APM deployment planning within your organization.
The planning stage is a perfect time to ask your APM vendor for documentation on best practices related to deploying their software. Your vendor (AppDynamics, wink) has seen their software deployed in many situations across many industry verticals. They will have important advice for you on how to make the deployment and operation of their product as successful as possible. Use your vendors depth and breadth of information to your advantage, you’re paying them so it’s the least they can do.
Controller: The Brain, Narf!
The first major decision will be an easy one. You probably already covered this during the evaluation, vendor selection, and negotiation phases but we will recap here. You need to decide if you will host your own controller or use the vendors SaaS environment. In case you don’t already know, a controller is the server component that collects, stores, analyzes, etc… the monitoring data from the agents. Basically the controller is the brains behind the operation. There are many factors that you need to consider when deciding to use a SaaS or On-Premise model and we will not cover them in this post. Your vendor of choice (ahem, ahem, AppDynamics, ahem) will help you decide which option is right for your business circumstances.
Easy peasy lemon squeazy! I have just embedded those words in your head for potentially days, weeks or years to come. Sorry about that but it really describes the SaaS option well. You don’t have to get a server racked, VM allocated, disk space configured, solve a Rubiks Cube in 3 minutes or less, or whatever other convoluted deployment process your company may have in order to host your own software. All you really need to do is point your agents at the SaaS controller and you are off and running. Your chosen APM vendor (AppDynamics of course) will handle the server sizing, capacity, maintenance, etc… for you. Nice!
So you’ve decided to host your own controller(s). We have many clients that choose this route for one reason or another and we make every effort to support you just as well as using the SaaS option. In this case we wont be doing all of the work for you so you need to get cracking on your server deployment process. I hope it’s super easy and streamlined and you can have a new host set up and ready to load software in an hour or less. In reality it may take you a few weeks or even months so you need to be familiar with the lead time so that you can appropriately plan the rest of the deployment. You NEED a controller so there is no point in deploying agents without one. Use this lead time to generate the most awesome plan ever!
Agents: Deploying and Configuring
Agents need applications to do anything meaningful so it’s a requirement that you figure out what applications you want (or will be allowed) to monitor. You most likely had at least one problematic yet important application in mind when you started your search for an APM tool. Create a list of the applications that need monitoring and prioritize that list. I personally prefer creating a top 10 list (you could also call it a “next 10” list) that is an equal mix of application I suspect will be difficult to instrument as well as applications I think will be really easy. I do this because you usually don’t work at deploying agents to application components in a serial manner. It’s typically a parallel process where you can jump from one deployment to the next while you are waiting for approvals, personnel, or anything else that gets in your way of doing actual work.
Deploying APM agents should be easy. Add a very small amount of software to the server you want to monitor, reference the agent software in your application configuration and restart your application. It’s basically that easy to deploy an agent. It should also be really easy to configure. In fact, the agent should automatically detect what it needs to monitor and simply just work. This is how AppDynamics works but the same does not hold true for most other APM vendors. Hopefully you saw this when you ran each vendor solution through your POC environment. In the interest of full disclosure I will admit that there are circumstances where NO APM solution can automatically detect your application properly and there is more configuration work to do. This is a problem that every APM vendor has to deal with but thankfully AppDynamics sees this condition with only a very small subset of its customer base. Usually you plug in our agent and we show you what you need to see. It just works!
Awesome, now that we just saved you 80% of the configuration time versus deploying “the other guys” what’s next?
After you deploy agents (whether it be straight to production or advancing though pre-production environments) and you have used the monitored application a bit, you want to look at the user interface to see if the information contained within looks correct.
- Look at your application flow map to see if you are missing any application components.
- Check the business transactions to see if the expected transactions are there and reporting metrics.
- Do you have end user experience metrics showing up?
- Do you have transaction snapshots showing your custom code executing in the run time?
- Send out test alerts to see if they make it to their destination. (Alerting is important so we will cover it in another blog post)
If things don’t look right you need to figure out why. It might be that your application really is different than you thought (we see this quite often), or it could be a problem with the monitoring. Resolve any issues you see before declaring deployment and configuration victory.
Production Load Cannot Be Simulated Exactly!!!
To realize the most value from your APM purchase you MUST run it in production. No matter how good your Quality Engineering team is they cannot code all of the crazy things your users will try to do in production. It can also be very difficult to duplicate your application environment in production. Example, you have 5000 JVMs spread across multiple cloud provider data centers. Replicating that environment would be time consuming and really expensive.
Beyond the technology aspects of running in production you also need to consider your existing processes. Your shiny new APM tool will provide incredible insight into application issues as long as you have it integrated into your processes. Here are some points to consider:
- Are alerts configured so that they are routed to the proper people?
- Does the operations center know about the new alerts that will be coming from your new APM product?
- Is there a process that application owners can follow to request monitoring by your new tool?
- Is there a process to smoothly and efficiently on-board a new application?
- Is the APM tool integrated with other corporate systems? (LDAP, Events Aggregations, Business Intelligence, etc…)
What I am trying to say is; Give your company every opportunity to use the hell out of your new tool!
Teach Them Well
Educate and evangelize, this will pay dividends ten fold.
Create a short training curriculum for anyone who will need to work with your APM tool. You should have training material for basic usage, advanced concepts (memory leaks, policies, dashboard creation, etc…), and operations (alerts/events) training. You need to make sure the people who will touch the product or consume the data have the information they need to be successful. Their success drives your success.
Tell everyone you can about the success you are having with your new tool. Don’t be annoying to the point where people run the other way when they see you coming but make sure they know what you are working on and how much of an impact it is having on the business.
For every problem you solve with your new APM tool take 30 minutes to put together a 3–5 slide presentation. Include the following information on each presentation you create:
- Problem Description: Describe the application, problem, and impact level.
- Resolution: Describe the resolution steps and root cause. Use screenshots from your APM tool.
- Business Impact: Describe how long it took to resolve the issue, how long it normally takes without APM, and quantify the impact to the business of this outage for both scenarios (with and without APM).
These short presentations will equip you with the information you need to defend your decision to purchase APM, justify a larger investment, and propel yourself to rockstar status within your organization.
There is a lot of work that needs to be done to successfully deploy, configure and use an APM tool in the enterprise but the potential rewards are staggering. Think about how much lost revenue can be avoided by ensuring your revenue generating applications don’t go down at peak times. People notice when the decisions you make and the work you do directly impact the bottom line. Put in the effort and get noticed!
Join me next week for the next installment in this series. It will be a blog post dedicated to alerts, yes they are that important.

Sharding has become a popular means of achieving scalability in application architectures in which read/write data separation is not only possible, but desirable to achieve new heights of concurrency. The premise is that by splitting up read and write duties, it is possible to get better overall performance at the cost of a slight delay in consistency. That is, it takes a bit of time to replicate changes initiated by a "write" to the read-only master database. It's eventually consistent, and it'...

Conferences agendas. Event navigation. Specific tasks, like buying a house or getting a car loan. If you've installed an app for any of these things you've installed what's known as a "disposable mobile app" or DMA. Apps designed for a single use-case and with the expectation they'll be "thrown away" like brochures. Deleted until needed again. These apps are necessarily small, agile and highly volatile. Sometimes existing only for a short time - say to support an event like an election, the Wor...

The cloud has transformed how we think about software quality. Instead of preventing failures, we must focus on automatic recovery from failure. In other words, resilience trumps traditional quality measures. Continuous delivery models further squeeze traditional notions of quality. Remember the venerable project management Iron Triangle? Among time, scope, and cost, you can only fix two or quality will suffer. Only in today's DevOps world, continuous testing, integration, and deployment upend...

Many people recognize DevOps as an enormous benefit – faster application deployment, automated toolchains, support of more granular updates, better cooperation across groups. However, less appreciated is the journey enterprise IT groups need to make to achieve this outcome. The plain fact is that established IT processes reflect a very different set of goals: stability, infrequent change, hands-on administration, and alignment with ITIL. So how does an enterprise IT organization implement change...

Containers and Docker are all the rage these days. In fact, containers — with Docker as the leading container implementation — have changed how we deploy systems, especially those comprised of microservices. Despite all the buzz, however, Docker and other containers are still relatively new and not yet mainstream. That being said, even early Docker adopters need a good monitoring tool, so last month we added Docker monitoring to SPM. We built it on top of spm-agent – the extensible framework f...
