15 Best Splunk Alternatives 2022

Splunk is an excellent tool. In fact, it’s one of the most encompassing, analytical, and widely used log-management software available.

The machine data analytics platform comes with its own SPL language for transforms, queries, visualizations, and statistical analysis. It’s also one of the most adaptable, flexible, and universal tools.

However, Splunk isn’t right for everyone, especially if you have a business that needs to monitor large data volumes. Thankfully, there are some better options on the market that can help you collect and centralize log data from a huge range of sources, with alerts, graphs, and other high-quality real-time monitoring capabilities.

Splunk has some drawbacks despite its feature-rich platform that make it a lousy option for businesses.

One of them is its high cost, which can be backbreaking for small and medium-sized businesses.

Plus, Splunk isn’t open source and has a slow search speed. Many developers have also raised concerns about its inability to handle large swaths of data and that it’s not as versatile as other tools in its category.

If you’re looking to switch from Splunk or want to check other options before making your decision, we’ve rounded up the 15 best Splunk alternatives you can pick from.

How To Choose The Best Splunk Alternatives

Splunk has several rivals, considering it’s not an open-source tool. However, you need to research multiple tools before opting for a paid subscription so that you find one that matches your business needs.

How do you get the best Splunk alternative? Check for the following:

Best Splunk Alternatives

1. SolarWinds Security Event Manager

SolarWinds Security Event Manager is a security, information, and event management (SIEM) tool that provides your business with next-generation analytics, detection, and response.

The software has centralized log collection so it will gather logs and apply threat intelligence to detect and respond to threats automatically.

The alerts are sent to you anytime there’s a security event, and they’re routed to your email for follow-up purposes.

SolarWinds comes with a dashboard, where you can see charts and graphs, automated threat detection and response, centralized log collection, notifications, and compliance reports.

With the dashboard view, you can see the events throughout your environment holistically through pie charts and graphs among other visualization options. This way, you can identify performance trends quickly like login failures by source machine for compromised machines.

Compliance reports help you audit your network and are regulated by PCI DSS, HIPAA, FISMA, SOX, GPG13, and GLBA.

It’s a good alternative because it can act as a log server, manager, and consolidator while providing a facility where you can view and sort messages before analyzing them. Plus, it can implement security scanning and you get a security monitor that would replace the functions in Splunk.

2. Loggly

Loggly is a free log monitoring tool based on SaaS that can process large data volumes from any source. You can see log events in real-time from different sources including mobile apps, databases, cloud platforms, operating systems, and more.

The dashboard displays an overview of your systems performance across the environment with metrics that drill down to the request level.

You can collect and aggregate logs, view graphs and charts to visualize performance, and get alerts and reports so you can analyze better and know what’s happening in your environments.

The software alerts you through Microsoft Teams, Slack, PagerDuty and other Webhook-compatible tools. You can also change the time period of a chart using the time feature to spot more performance concerns or use the prebuilt templates to develop your own dashboard.

What makes Loggly better than Splunk is that it comes with a barebones free edition, which Splunk doesn’t provide. Plus, Loggly has several custom-built features that enhance search results making log search faster compared to Splunk, which is fast when searching for short time windows.

And while Splunk uses distributed tracing for events, performance issues, and failures, Loggly uses a common trace ID to isolate logs for specific requests, events, or transactions to give you a common view of events and impacted systems.

Loggly also generates log views based on their customized views and inherent structures while Splunk has a monitoring console that views log index and volume status to give you health checks of multiple deployments.

3. Datadog

This is a log management and cloud monitoring solution that lets you collect log data centrally from any source. You can search, collect, and filter your logs to identify security events, which you can view through graphs or charts on your dashboard.

There are several major differences between Datadog and Splunk which can help you make the choice between the two. Splunk is a log management tool while Datadog is a monitoring and analytics tool that your IT and DevOps team can use to monitor your environment.

Datadog is also useful in integrating other products to measure performance better, while Splunk lacks this functionality.

Splunk also requires technical support to install it on the system while Datadog comes with easy-to-use features for implementing and installing it. When it comes to programming languages, Datadog supports PHP, JAVA, Ruby, Node, Python, .NET and Go while Splunk doesn’t have standards for using such languages.

Datadog can send alerts and alarms when an issue crops up in the system so you can act immediately but Splunk lacks these additional tools – the system admin handles the alerts.

Other differences include that Datadog monitors the performance of your environment while Splunk monitors your data and converts it into a readable format for analysis. Datadog’s customized dashboards make it functional for performance monitoring, while Splunk needs to be used as is.

Finally, Datadog supports multi-cloud visibility to monitor the performance and data of cloud services while Splunk analyzes log files generated from the systems.

4. Sumo Logic

Sumo Logic is a log management tool based on SaaS that you can use to monitor services in the cloud or on-premises. The platform has a wide range of integrations for Google Cloud, AWS, Kubernetes, Microsoft Azure, and Docker so it can fit with your current services and tools.

The software features log collection, charts and graphs in the dashboard, real-time alerts, threat intelligence, and integrations all of which help you get a comprehensive view of security events.

Sumo Logic is offered in the cloud as SaaS to its users, while Splunk is offered on-premises though it has a limited cloud product. Sumo Logic’s data models design should be finalized upfront and data extraction follows this pattern, while Splunk lets you store data in indices and you can do data modeling flexibly during run time.

Sumo Logic is a cost-effective solution for SMBs, while Splunk is expensive and best for large companies with a larger user base. Sumo Logic has fewer apps in its stable than Splunk, but Sumo Logic has an app integration facility in the cloud, which Splunk lacks.
