Why do I need a log analyzer?
Every single device or application connected to your network creates log files. Network administrators use these log files to view performance data. These tools are useful because they provide access to the data that the user wouldn’t otherwise have. A log analyzer collects data from a device’s log files and translates it into a data format that’s easy to read.
On a log analysis tool, this ranges from a graph display performance data to smaller dials. Reading performance data in a centralized format like this is much easier than reading through log files directly as text files.

All displays are top-notch and can be read with a glimpse. However, you can create unique log analytics dashboards by drag-and-drop if you require further customization. Log data can be viewed in real-time and historically. Once Datadog has recorded log data you can use filters to determine what information is listed.
To keep log data from being compromised, Datadog uses centralized data storage so that no data is left on the server. The main benefit of centralized data storage is that your data is protected in the event of an outage.
There are also smart alerts that use machine learning to detect anomalous log patterns and errors. Alerts can be sent through tools like Slack and PagerDuty so that your staff knows the moment there is an issue. You can also set your own alerts with Boolean logic to make sure that you don’t miss anything.
A data viewer in the system dashboard enables log files to be loaded and analyzed. An optional storage space package is also available.
Who is it recommended for?
As it is a cloud-based platform, Datadog is convenient for use by any business anywhere. It can centralize log management for multiple sites and even provide one point of storage for multinationals.

6. Loggly (FREE TRIAL)
Loggly is a cloud-based log consolidator that is available as a subscription service. You can pay for the Loggly service monthly or yearly, and there is even a plan that is free to use.
Key Features:
- Cloud-based
- Log consolidator
- Log storage space
Why do we recommend it?
Loggly is a similar service to Papertrail because both of these systems are based in the cloud and they can accept log messages from just about any type of system, including cloud platforms. The Loggly service automatically generates log message throughput statistics and you can implement your own analysis on log contents.
The online format of the service means that you don’t need to install or maintain software on your premises. However, you do need to set up periodic log file uploads. This task is guided by a Loggly wizard.
The main attraction of this service is its analysis utilities. To unify all log file records from disparate sources, the Loggly system standardizes the information in uploaded records and stores them in a standardized format. Loggly can handle records from many different sources, not just the standard operating system event logs from your servers. It can also take in logs from Amazon Web Services and applications such as Docker.
The Loggly service is available in three plan levels: Lite, Standard, and Enterprise. Loggly Lite is the free service. This has most of the features of the standard Loggly system except that it has volume limits. You are only allowed to upload 200 MB of log data per day with this service. Another limit on the free service is that it will only retain records for seven days. These restrictions may encourage you to opt for the paid version. The higher of the two charged plans, Loggly Enterprise is a bespoke package, which allows you to specify a data volume for your subscription – and it is priced accordingly.
Who is it recommended for?
The free Loggly option is called the Lite plan and it permits a throughput of 200 MB per day, which is a much larger allowance than that offered by Paprtrail and is sufficient for many small businesses. The highest plan provides much more automation, including alert channeling to third-party tools.
Pros:
- Lives in the cloud, allowing syslogs servers to scale regardless of onsite infrastructure
- Setup is easy, no lengthy onboarding process
- Can pull logs from cloud platforms such as AWS, Docker, etc.
- Data is immediately available for review and analysis
- Offers a completely free version with limited retention
Cons:
