This package consolidated and files logs as well as searching them.

A dashboard view provides a holistic perspective of events throughout your environment. There is a range of visualization options such as graphs and pie charts that allow you to identify performance trends at a glance. For example, you can view Login Failures by Source Machine pie chart to help identify compromised machines.

Compliance reports enable you to audit your environment easily. There are out-of-the-box compliance reports available for regulations such as HIPAA, PCI DSS, SOX, FISMA, GLBA, GPG13, and more. Reports can be customized or generated with built-in templates.

Who is it recommended for?

This is one SIEM option that any business should consider. It is easier to set up than Splunk and you have fewer deployment options – this tool is only available for on-premises installation on Windows Server and there is no cloud version. The service also provides log management.


  • Comprehensive SIEM Solution: Offers robust log management and threat detection tailored for enterprise needs.
  • User-Friendly Interface: Simplifies log analysis without requiring complex query languages.
  • Ready-to-Use Templates: Facilitates quick setup with numerous templates for immediate operational capability.

A customizable dashboard offers graphs and charts you can use to visualize performance. The time shift feature allows you to change the time period a particular chart shows helping you to spot performance concerns more easily. If you don’t want to build your own dashboard then you can use one of the prebuilt templates instead.

Create alerts to notify you about security events in your environments. The software sends alerts by Slack, PagerDuty, Microsoft Teams, and other Webhook-compatible services so that you always receive the latest information. If you wish to create a report then you can convert the dashboard into one and export it in PNG format.

Who is it recommended for?

This system is a good tool for businesses that need to manage, file, and archive log messages. This task is necessary for compliance with data protection standards such as PCI DSS. The SaaS package is available in a free version, called Lite, which has a low data throughput allowance.


  • Cloud-Based Flexibility: Adapts to any scale without the need for onsite infrastructure adjustments.

One sensor that’s useful for log management is the Windows Event Log Sensor, which you can use to monitor Windows log files, including system and application logs. Another valuable sensor is the Syslog Receiver Sensor, which allows you to monitor the number of received syslog messages per second, number of warning messages per second, number of error messages per second, and more.

With threshold-based alerts, you can configure Paessler PRTG Network Monitor to send you notifications whenever a key parameter is exceeded. The system can send notifications as email, SMS messages, push notifications, Slack messages, SNMP traps, or automatically respond by executing HTTP actions or programs.

Who is it recommended for?

The PRTG tool is great for monitoring networks, servers, and applications. it is a collection of a lot of monitors and the log sensors are just two of them. The system is free if you only activate 100 sensors. Access PRTG on its SaaS platform or download the software onto Windows Server.

7. Site24x7 Log Management (FREE TRIAL)

site24x7 log management tool dashboard screenshot

Site24x7 Log Management is a service on the Site24x7 cloud platform. The platform installs a collection agent on the monitored network and that unit collects circulating log messages. The system will gather logs from operating systems and software packages and the service includes storage space for log files.

Key Features:

  • Diverse Log Collection: Supports both Syslog and Windows Events, ensuring comprehensive log gathering.
  • Efficient Log Uploads: Facilitates the easy uploading of logs for centralized management.
  • Advanced Log Parsing: Converts logs into a standardized format for uniform analysis.
  • Flexible Log Forwarding: Enables the redirection of logs to other systems or applications as needed.
  • In-Depth Log Analysis: Offers tools for detailed examination and interpretation of log data.

Why do we recommend it?

The Site24x7 Log Management system is part of a platform of system monitoring and management tools. So, you don’t just get a log manager within this package, you get all of the tools needed to run an IT system. The log manager can be used to construct performance monitoring or security monitoring systems.

The log server receives all log messages, converts them into a standard format, and tags them according to source. The dashboard shows statistics about the arriving log messages, mainly about volumes per source and overall. These statistics about messages can have alerts placed on them. So, for example, if log rates suddenly drop or surge, the network manager would probably need to know.

The system can be set up to forward alerts to technicians as notifications. These can be sent by SMS, push notification, voice call, email, or Slack message. It is also possible to set up your own alerts within the log message data viewer. That utility includes basic analytical tools and you can store your searches to run repeatedly and then name processes to launch if a specific condition is detected. Thus, you can create your own early warning system for performance problems or security issues.

Who is it recommended for?

This log manager is primarily designed to consolidate and store log messages. It provides log volume statistics and has a data viewer that can implement data analysis. However, its data analytics capabilities are not as powerful as those available in Splunk. The tool can be used to filter messages and pass them through to third-party tools for action.


  • Versatile Data Viewer: Comes equipped with robust sort, filter, and grouping capabilities for log analysis.
  • Trigger-Based Searches: Allows the creation of search-based triggers for automated response actions.
  • Automated Process Capabilities: Provides options for process automation based on log analysis outcomes.

Mezmo Log Analysis is very similar to the base package of Splunk because you can use its query tool to mine log messages for data and create your own security or performance assessment system. The log manager includes a filtering and query language to parse and selectively forward or consolidate and file messages.

Alerts notify you about system events immediately. The platform integrates with over services such as PagerDuty, Slack, Webhook, and other APIs, so you can receive alerts to wherever you and your team are most active. Usage reporting provides you with an update on your log usage so you can see when you need to manage resource consumption.

Team controls provide you with multiple features you can use to support an entire team. For example, role-based access control enables you to limit access to sensitive data, and SSO/SAML user authentication makes sure that only authorized users can access protected data.

Who is it recommended for?

This package is suitable for businesses that want to develop their own in-house monitoring tool for performance or security analysis. There are few out-of-the-box features because this is more of a framework of tools, just like Splunk. The company also recommends the platform for the development of applications for sale to other businesses.


  • Intuitive Interface: Boasts a clean, minimalistic design that emphasizes crucial data points for quicker insights.
  • Flexible Filtering: Features robust exclusion rules that are straightforward to customize, enhancing log data relevance.

The Mezmo platform also offers a distributed tracing function as a separate service. Both of these services are available from the cloud and are provided on a subscription basis. The Log Analysis module has a Community Edition, which is free to use. This has no data retention option and so you would need to set up immediate forwarding with that option. The cheapest paid edition is called Professional and it offers 25 user accounts. The price starts at $0.80 per GB of data with a three-day retention period. You can get a 14-day free trial of this edition.

Choosing a Splunk Alternative

We highly recommend researching multiple tools before committing to a purchase to ensure you adopt a solution that closely matches your requirements.
