Splunk alerts

What is Splunk?

Splunk is a big data tool that captures, stores and correlates data in real-time and in a form that you can search for specific pieces of that data. It also generates everything from dashboards, various visual outputs, and alerts. Given the high volume of data that Splunk takes in, a critical piece of the tool it’s analyzation capabilities and ability to set up Splunk alerts, which will help you monitor events in real-time as they happen. Let’s dive into those alerts a bit deeper and see what they can offer you and your company, no matter the size or industry if your business.

Creating real-time alerts

One of the best kind of Splunk alerts you can set up is a per result alert, which triggers alerts to you and your team anytime a certain pattern of events happens. It can be critical in identifying trends and when you schedule them you can save valuable network resources. You can also set up “windows” of time, that give you intervals of say 10 minutes for example, to look for pattern for events. This is another good method if you are limited on resources.

Scheduled alerts

Another form of Splunk alerts to be aware of are scheduled alerts. In scheduled Splunk alerts, you can track things such as an error during a Splunk instance and get pushed an email alert if there are more say 10 errors in a twelve-hour window of time. You can schedule this same alert to say every day at the same time, depending on when your networks and servers see the most action over them. You can also trigger the email alert if the search has more than say seven results. You can have the emails come daily, at the time of the event, or get a weekly email detailing results. Email alerts can be a great feature because you can stay up to date around the clock, just by checking your email.

Custom field Splunk alert

As you get comfortable with Splunk and its functionalities, you need to define what exact criteria you’ll be looking for when it comes to everything from security to bandwidth. Whether you have an in-house app developer or use a third party, you’ll want to make sure the custom Splunk alerts are configurable by you and your staff. The alerts and rules you set are only as good you understand them, and more importantly can react to them. You can also convert a custom script into a Splunk alert action, customizing the alert to your company and the specific events that you normally see. Those scripts can come via SQL, or various other programming languages.

Splunk dashboards and alerts method

Whether you choose to get your alerts via email or within your dashboard, you’ll want to make sure your system is intuitive and one you can pick up quickly. Make sure your staff is trained to recognized alerts and what to do with them, so you can neutralize or react to anything that comes your way. Another increasingly popular way to get alerts is via SMS, which allows true around the clock and mobile reaction times. Many tools and resources now also offer a mobile version of their tool, which is great for those on the go professional or those that work remote. Downloading a trial demo version of any software you are considering is good practice, and the one that handles your Splunk alerts should be no different.
