What is Splunk?




Splunk is a Software product that helps you to search, analyze, visualize, report, and alert on the machine data it collects from any system or component. It is primarily used as a log aggregator letting users search insightful data from huge volumes of indexed logs.

Splunk Enterprise Solution is capable of ingesting data from almost anywhere such as sensors, devices, applications, and websites. This data can then be filtered and ingested by indexers which in turn convert it to individual events, ready to be queried and filtered. The product can be hosted and supported in-house or could be subscribed to over the cloud. Splunk is increasingly focusing on machine learning and Artificial Intelligence, providing users with features like predictive analytics, outlier detection, and forecasting time series, which helps them detect pattern deviations and notify issues even before it occurs.

What's the difference?




When to choose what?

‍If you are still confused about what to select – Let’s get this straight.

Make Grafana your partner if you have data expressed as numbers over time. Grafana is best used to represent time-series data (i.e. numeric data points sequenced over intervals of time) and it can generate colorful visualizations out of them. These data can be represented in real time over various types of panels and dashboards letting the users monitor different KPIs effortlessly. Grafana is also open-source, free, and easy to manage/set up. With newer containerized technologies like docker, pre-saved images and configs could be set up in a couple of minutes with only a few commands.

Grafana is your tool if you need a product only for data visualization without spending a fortune on it. You can easily integrate it with simple and low-maintenance time-series databases like Graphite. Now, if Grafana is the right choice for you and installation and setups are just not your thing, check out Hosted Graphite. It’s a cloud-hosted offering that's taking care of monitoring, graphing, and alerting at any scale. Read more on monitoring with Graphite here.

Splunk is your product if you need a more versatile solution that can ingest any kind of data or logs and give you the capabilities to query and search through the data quickly. Splunk is mostly used as a log-aggregator that continuously takes in logs or any kind of streamed data, then indexes and stores this data in indexers, and gives you the capability of searching and filtering using search heads. Splunk’s power lies in indexing data that could be in any form and could come from anywhere irrespective of whether they are formatted or not. Splunk makes it searchable for you.

However, with great power comes great maintenance and cost. Splunk is a premium licensed product and setup for an Enterprise ingesting large volumes of logs would take a good amount of expertise, effort, and strategies to make it work and be successful. Also, Splunk Enterprise solution prices customers based on the amount of data indexed, so you might want to restrict indexing to important data only, as it increases your resource cost for maintenance.

If you are a large enterprise and are susceptible to multiple daily issues with systems, infrastructure, applications, etc. that directly impacts your revenue, Splunk might sound like a great investment and could help your support teams to troubleshoot issues faster. With the support of Artificial Intelligence and machine learning, issues could be detected even before they occur, saving downtime and revenue loss. So, choose Splunk only if you need its power and abilities of it. As the saying goes - “Don’t buy a Ferrari just to put it in your garage”.
