Monitoring your Load Balancer for Actionable Insight in 5 Simple Steps – How to install Kemp 360 Vision
If you have deployed a load balancer you are on the road to full application availability as a result of application redundancy.
This is great, but in order to fully optimise your application delivery and minimise downtime risk, implementing monitoring of your application delivery is key. I believe the load balancer is a great resource to monitor in order to gather actionable insight into your application (see Top 10 Reasons to Monitor your Load Balancer).
While many advanced monitoring tools exist it can be difficult to distal the unlimited data points into the most impactful information. In today’s complex networks, processing data across multiple vendors will likely result in data-fatigue.
Kemp 360 Vision is designed to provide a simple way to monitor your application delivery for the most common issues and present this insight in an easily consumable format. Vision doesn’t just tell you something is down it also tells you the impact and provides you with context such as how regularly this occurs and recommended remediation steps.
Best of all, Vision can be set up in a matter of minutes with just 5 simple steps:
Step 1: Sign In and Create a Kemp 360 Vision Agent
The first thing you need to do is login to https://Vision.kemptechnologies.com. This will create your Vision Account. Once here your first action is to create a Vision Agent. You only need to add a few pieces of information and Vision will create a Virtual Machine for
deployment in your network. For requirements see here.
Step 2: Deploy the Kemp 360 Vision Agent in your environment
Once the Vision Agent has been created and downloaded, deploying it in your network is easy. Once downloaded, simply unzip the file and deploy in your chosen Hypervisor.
Once the VM is created, power it on and within about a minute it should connect back to the Vision service.
This can be seen in the User Interface as shown.
If the agent has been turned on but doesn’t connect it could mean there is a firewall rule blocking the connection. You can run a diagnostics from the Vision agent (see here).
Step 3: Point Vision At Your Load Balancer
Now you can add resources for monitoring. The most insightful resource to add is your load balancer cluster. Vision supports Kemp LoadMaster, F5 or NGINX.
Step 4: Setup your preferred Communications Channel
Now you are monitoring your need to configure notifications through desired communication channels. There are 3 options here email, slack or sms. This should enable you to receive notifications whether in the office or on the go to the appropriate channel.
Once a communications channel is added this needs to be verified. Simply click on the link contained in the sent email to do this.
Step 5: Tune and Test
Now the cluster is added and you have a communication channel enabled you are ready to go!
You can customise which applications you wish to receive notifications for by clicking on the cluster and going to the ‘Edit’ page. You may also configure maintenance schedules – these are times in which maintenance is completed and you do not want to receive any notifications.
Since my applications are still not live, in order to test I will cause both my HTTPs Servers to fail. This would mean anyone accessing my Web service application would be unable to connect if this was live.
As you can see from the LoadMaster user interface, Web Service HTTPs is now unavailable.
Shortly after (around 2 minutes) I receive a notification to my chosen email address. As you will see this doesn’t just tell me the application is down but includes the following insight:
- Highlights the relevant Real Servers
- Indicates if it is likely a server or specific application issue.
- Highlights previous occurrences,
- Checks for recent configuration changes
- Gives remediation advice.
Most importantly the notification enables the me to engage with Kemp Customer Support promptly if application delivery assistance is required. This could be very useful in times of application outage
A full list of all the application delivery issues detected by Vision can be found here.
As you can see getting from a load balanced application to a load balanced application with monitoring and actionable insight takes just a few simple steps but offers massive additional value. So, what’s stopping you – simply sign in a complete setup – you will not regret it!
