10 Best Splunk Alternatives to Consider in 2023
Splunk is a data management and analysis platform that allows you to observe, search, analyze, visualize, and create reports on vast amounts of machine data so that you can easily make sense of the data and use it to increase the efficiency and productivity of your business.
As machine data is often complex and unstructured, making sense of it can be a tedious process, especially when considering the volume of the data. By using a platform like Splunk, you can process such data in real-time and extract the relevant data so that you can pinpoint the source of the problems on your system.
It is an enterprise-ready solution with several offerings that you can take advantage of to reach full-observability of your infrastructure. For example, you can ingest and index all kinds of data from your entire stack and use this data to detect anomalies, identify performance trends, or correlate events. Splunk is also a big data analytics platform and SIEM solution.
The most significant downsides to Splunk are its setup complexity, price tag, performance with large datasets, and outdated user interface, which make it an unsuitable solution for many businesses especially for small and mid-sized organizations. Several Splunk alternatives may prove a better fit for monitoring, observability, and log management.
In this article, We'll discuss 10 of the best ones along with their pros and cons to help you make the best choice.
1. Better Stack
Better Stack is an observability platform that helps you collect insights across your stack, detect critical incidents, and escalate appropriately. It does this through its two main products: Logtail, which is focused on log management and Better Uptime for monitoring and incident management.
Logtail is a ClickHouse-powered log management and analysis tool that offers sophisticated data collection, processing and reporting features. It is an excellent Splunk alternative that provides tools for collecting data across your entire stack and centralizing them in one place.
It integrates seamlessly with a host of technologies like Kubernetes, Heroku, Logstash, Rails, Docker, AWS, etc, and you can ingest and ship your data using any log shipper of your choice. Thanks to custom-built technology and ClickHouse , you can search and filter your logs quickly and efficiently, and receive automated alerts when something goes wrong.
Tighter security is one of the main priorities in log monitoring, and Logtail itself is one of the most secure tools available. Using industry-standard best practices and cooperating only with data centers compliant with DIN ISO/IEC27001 certifications, your data is safe during both transit and storage.
With Better Uptime, you can also set up uptime monitoring for your applications, APIs, Cron jobs, and more, with on-call scheduling, so that the right person gets notified promptly if something happens. Several integrations are available and you can also create a branded status page to communicate incidents, planned maintenances and other developments with your users.
Both products provide a free plan with generous limits where you can get to experience them and evaluate if they meet your needs and the paid plans for each start at $24/month.
2. Elastic Stack (ELK Stack)
The Elastic Stack (formerly known as the ELK Stack) is an open-source log management solution that comprises four distinct tools:
- Elasticsearch: a distributed JSON-based search and analytics engine.
- Logstash: for log ingestion and pipeline processing.
- Kibana: data visualization for Elastic search.
- Beats: a set of lightweight single-purpose data shippers.
Since Elastic Stack's core components are open source, you can download and run it without cost. When you install the stack, you'll immediately get access to all the tools you need to collect data from multiple sources, process it, and store it in one centralized location that can scale as data grows. You'll also be able to view and analyze the data through a web-based user interface.
A crucial advantage of the Elastic Stack over Splunk (due to its open source nature) is access to a massive community of developers and library of plugins for extending the capabilities of the stack. On the other hand, the Elastic Stack can be quite complex to setup and configure before it can function as a production-grade log management tool, and your data needs to be well structured before you can get the most out of it, while Splunk is more usable with unstructured data.
3. New Relic
New Relic is another observability tool primarily used to monitor application and infrastructure performance. It started as an APM but has evolved into a full observability suite with tools for log management, network monitoring, Kubernetes monitoring, and many more for monitoring mobile, web, and cloud applications in real-time. These features overlap with Splunk's infrastructure monitoring solutions making New Relic a worthy alternative to consider if such monitoring feature in your primary observability needs.
Their standard offering provides the ability to ingest up to 100 GB of data for free with just one full platform user. Additional costs depend mostly on the amount of data ingested ($0.30/GB beyond the free limits) and how many full platform users are required. You can check out their pricing page for further details.
Dynatrace is a Splunk alternative that offers a plethora of observability products ranging from application and infrastructure monitoring to cloud automation, security, and log management. It uses its OneAgent technology to collect performance metrics for the various kinds of entities in your environment (servers, databases, containers, and more) and unifies them in one place. Once the data collection pipeline is setup, you'd be able to use the following proprietary technologies to gain insights into your infrastructure:
- Smartscape for detecting causing dependencies across your entire environment.
- PurePath for end-to-end application tracing.
- Davis AI for automated remediation of detected problems.
Note that Dynatrace can be deployed on-premise or adopted as a SaaS solution, whichever is more appropriate for your use case. Dynatrace also offers a quite unique pricing model based on the monitoring units that are utilized in your Dynatrace deployment. A free trial is also offered so that you can evaluate Dynatrace's products and services without cost.
