When running an application or website, you’d be wise to not only keep track of your visitor statistics, but your performance as well. While we’re used to setting up downtime monitoring right after deployment, this isn’t always the case with performance monitoring. A slow site means a slow income, especially nowadays when visitors expect sites to load in just a couple of seconds.

With excellent tools like New Relic around, application performance monitoring and management shouldn’t be such a hassle anymore. Better yet, they recently teamed up with Loggly, a service that provides log management and analysis for an even better insight into your application or site’s performance. Now you can easily dive further from what happened into how it happened.

In this article I will show you how both New Relic and Loggly work as a combined tool. Once you get the basics I will show you how these two powerful tools combine into a developers dream for analyzing bad performance or downtime.

Why you should use Application Performance Management (APM)

New Relic welcome screen

You may have heard of New Relic before as they have had various great partnerships with SitePoint. They were also covered in detail by Darren Jones in his excellent article on real time Ruby monitoring.

New Relic offers several solutions for application performance management (APM). Whether you want to monitor your web application, mobile app or server, New Relic has the right tools for the job. They also have a free version of all of their products. For this article I will focus on New Relic APM, and let you have a look into its impressive dashboard.

New Relic's dashboard

For New Relic to work properly, you’ll need to have admin access to the server your app is running on. Once installed, your dashboard will come alive. After running a small load test you’ll get to see your app (a Magento webshop in my case) in action.

Initial load test for a Magento web app

The dashboard shows you the average loading times for your PHP application, the database and external sources (DNS for example). You can also see your throughput (75 requests per minute in this screenshot) and APDEX score (which is basically a satisfaction rate based on an average loading time of 0.5 seconds as default). You can then further zoom in on all of these parameters, like the external sources loading time or database calls.

New Relic allows you to zoom in on various loading parameters

There is also limited server information with CPU and memory usage, along with throughput and response time. For more extended server monitoring you should use New Relic Servers, but even in limited mode this is still valuable information.

Simple graphs of CPU usage

Since New Relic gives you real time reporting, you can instantly see the effect of changes you make. When running a second load test I turned on Magento cache during the test, causing an instant drop in PHP load times as well as fewer database queries. New Relic gives you a nice view of the results right away.

Along with real time reporting there are tons of additional reports for you to run. You can also set up alerts for specific events like downtime or slowdowns.

All in all, New Relic is a great tool for performance testing, but in some cases you’ll want to dive in deeper and look at your logs for detailed analysis. This is where Loggly comes in. It has an integration for New Relic which makes it very convenient to jump from an event from New Relic into logs hosted by Loggly. Let’s have a look.

Why you should value your logs

Loggly dashboard

Loggly is all about log management and analysis, and they provide you with some nifty tools to do this. Setting up is simple, with a couple of commands in the command line. After that, you’re in log heaven. Loggly gives you insight into every detail of your application.

Loggly reporting an app is out of memory

Where New Relic tells you what’s happening on the front-end, Loggly gives you an insight into what’s happening throughout your stack. In my screenshot you can see Loggly is reporting that my instance ran out of memory. New Relic, however, was only showing “lower” or “no” performance, because they don’t measure your server’s memory limit. Without Loggly, I simply wouldn’t have known what happened in this case.

Loggly displays the number of restarts from a web app

In the screenshot above, you’ll see the logs of multiple restarts in a short time. As you can see Loggly gives you extremely detailed information on the buildup of downtime on various levels. Loggly has a granular approach, as each event is stored separately where New Relic aggregates them.

An error or performance issue can have several underlying causes, but New Relic only shows you the end result and its impact. With Loggly you can trace each event back to its origins and see what happened in the moments before it occurred. It also allows you to pinpoint a specific user’s issue for example. Also when browsing through the logs I noticed someone tried to log in as root, an attempt which was blocked. This is all valuable information which New Relic can’t provide and Loggly does perfectly.

Loggly gives you multiple ways of building your own custom dashboards to monitor your apps or even sections of your app or site. You can integrate it with other tools like PagerDuty or HipChat for advanced notification. You can also set up various alerts within Loggly itself and it has an universal search bar to quickly get the relevant logs based on your search terms.

Browsing through tons of logs can be a tedious task, especially when you can’t really pin down what each entry meant on the front-end. To help you in your analysis, New Relic and Loggly teamed up to provide you an excellent integration. Using a Chrome extension, you can simply click on an event reported by New Relic and find the matching logs in Loggly. Let’s see how that works.

Getting the best of both worlds: Combining APM with log management for a detailed breakdown analysis

New Relic and Loggly on their own provide excellent ways of tackling problems in performance. But when doing an analysis you can’t easily put them back-to-back without constant switching. Especially with more popular apps or sites we’re talking in milliseconds, with tens or even hundreds of events and transactions happening each second.

For a solution, install the “New Relic – Loggly Extension“. After you’ve done that, you’ll get an “Search Events in Loggly” button on each error and event screen in New Relic.

Loggly's event search functionality

Every time you are looking at an event, error or transaction and you hit that button, the exact date and time parameters are passed on to Loggly. This way you’ll get a perfect match in Loggly without further adjustment of time. Loggly then allows you to scroll through its full log so you can see everything that happened before the actual event occurred.

Let’s have a look at a few load tests I did on my demo site. I loaded up the homepage with a number of products and turned the caching off, which leads to a lot of database calls for each visit. I then fired up a load tester (Load Impact) with 50 concurrent users and within a minute the site went down. After the first test I turned the cache back on and ran the same test but this time with 100 concurrent users. Again within a minute the site went down.

A load test for a web app

After a few minutes New Relic caught up so I could analyse what caused the actual downtime. I expected the database to break right away, but with cache turned on this shouldn’t be the case. Both times there were tens of PHP transactions (100 max at the second test), but in both cases the database was used even when caching was on (this could be due to widgets not being cached, for example).

Hitting the “Search Events in Loggly” button gave me the exact same timeframe so I could start digging. After comparing several events, it turned out that both Apache and MySQL ran out of memory. Apache was mostly responsible with cache turned on, but even then MySQL could be the one to give the final blow.

Investigating logs with Loggly

So the simple solution would be to upgrade the instance the web store was running on. It went from 512MB with a 1 core processor to 8GB with a 4 core processor.

A second load test

After the upgrade I ran an additional test, with cache turned on and 50 concurrent users. Again database calls were still done, but the performance was pretty consistent (although a bit slow) and there was no downtime.

Loggly was pretty happy too, with the only event being the instance re-sizing. Even though this is a pretty basic example, it does show how easy it is to analyze events in Loggly based on specific moments you see in New Relic. The Chrome extension makes switching a breeze.

That’s really all there is. But even though this sounds simple, it will save you a tremendous amount of time when you want to analyze multiple events. You can get the Chrome extension without additional cost, and setting up takes less than a minute (just enter your Loggly account name).

Get inspired: How you could benefit from APM with log management
New Relic and Loggly are a powerful combination, with both having enough features and tools to quickly analyze a problem and determine its cause. But my demo is just one example. While this is a common issue, finding a quick fix isn’t rocket science. But upgrading your instance is a short term solution as it will keep occurring when your web store becomes more popular.

What if you would want to have a closer look at why there are still database calls even with caching turned on? Or how about a slow performing checkout process, where caching wouldn’t help due the dynamic nature of the actual process?

Conclusion

Both New Relic and Loggly are effective tools to first identify a given problem, then isolate a specific occurrence after which you can reverse engineer the problem and find a solution. Everything is done in (almost) real time and in more detail than you will probably need (but it never hurts to have them).

Loggly has built a great interface for wading through your logs and finding what matters from among their millions of entries. But let’s not forget: they don’t just offer an analysis tool, they also store your logs as well. With a popular app or site your log growth will quickly become insane, sometimes turning into a performance problem on its own. Loggly does all the storing and backing up, so you won’t risk losing your valuable logs after a server has gone completely crazy.

Both New Relic and Loggly have free trials, for 14 days and 30 days respectively. They also offer Lite plans with New Relic having a 24-hour data retention and Loggly 7 days. This is sufficient for real time monitoring with the option for analysis afterwards.
