New Relic Monitoring for Your Application inside the Cloud
New Relic is an application performance monitoring (APM) tool for Developers and Ops, focused on providing the deep insight into the project’s performance and reliability in real-time. Designed to pinpoint and diagnose the occurred issues, it can track throughput of your web transactions, analyze application exceptions, find slowness in queries or web requests and, generally, gives the great amount of useful data for the fast and comfortable troubleshooting.
Since New Relic is one of the most frequently used and extremely popular solutions for supervising application metrics, we have prepared a special add-on to simplify its delivery. Implemented on the base of JPS (Jelastic Packaging Standard), it gives opportunity to install this software in a single mouse click and start tracking the most crucial application server information in a matter of minutes. In addition, you can always stay up-to-date with the embedded option for automatic installation of available New Relic updates.
So, let’s explore how to unveil the latent performance capacities of your application with the help of New Relic - to proceed with the add-on installation, you’ll need to have:
- the already registered New Relic account, with your unique user identifier (i.e. license key)
- at least a single environment created at any of our partners’ Platforms, with the deployed app you’d like to track
Once these conditions are fulfilled, you can easily integrate New Relic agent to your cloud environment - just follow the steps below.
New Relic Add-on Installation
Anyway, the installation flow remains similar - so, as an example, we’ll use a Java environment with Tomcat application server.
To start with, click the Marketplace button at the top dashboard pane.
Switch to the Add-ons section in the opened tab, find the New Relic APM solution within the appeared list (you can use the search input above) and click on Install for it.
You’ll see the installation frame appeared: Here, the following data should be specified within the appropriate fields:
- Application name - enter the label for this app to be shown at your New Relic dashboard, e.g. my-project (an environment domain is substituted by default here if switching among several available ones)
- License key - a unique identifier, that is bound to each New Relic user and can be viewed at the Account settings section of its admin panel (stating it, you ensure that the collected data will be reported at your account)
The License key field at add-on installation frame contains the key mask by default. You can complete the installation leaving it unchanged, but, obviously, you won’t be able to explore the gathered statistics (because of the absence of the bound New Relic account).
Nevertheless, you can specify this parameter later within the New Relic add-on settings by means of the Jelastic Configuration Manager.The paths for the required file are:
- for Java app servers:
- TomEE, Tomcat 6, 7, 8, 9 - /opt/tomcat/lib/newrelic/newrelic.yml
- Jetty 6, 8, 9 - /opt/jetty/lib/newrelic/newrelic.yml
- for PHP app servers: the appropriate parameter can be found at the very end of the etc/php.ini file (within the [newrelic] section)
Besides, the rest of add-on parameters can be modified within these files too.
- Environment name - select the name of environment the New Relic agent should be installed to (the suitable ones are highlighted within the drop-down list)
- Nodes - pick the instance for being monitored (currently, only application servers are available for choosing) Click the Install button to confirm your entries and initiate the deployment process.
In several minutes, the add-on will be added to your application:
According to the above shown pop-up, you need to obligatory Restart node(s) to start gathering your app’s efficiency trends. This can be performed with the appropriate button next to your application server.Note: Please, pay attention that if your project is run in a single app server node, the restart will cause a temporary downtime of your application, thus we leave for you to decide when to perform this operation.
However, in case your app server is scaled horizontally, the downtime will be minimized, since all the server instances will be restarted sequentially. And starting with 4.9 Jelastic version, you are able to get rid of this inconvenience at all, through setting the delay for executing this operation at each next node within a layer. In such a way, whilst one node is undergoing the maintenance, the rest ones will remain active.
Now, you can log in to your New Relic account and look inside the collected data on your application performance metrics. Keep an eye on the most crucial parameters in real time through your custom report dashboards, get the automatic notifications on the critical issues occurred and much more - see the full list of the provided monitoring features.
As you can see, the New Relic add-on installation is really simple and will not take much time. At the same time, it’s powerful enough to help dealing with arisen problems and doing away with lack of performance.
