Sematext Review and Alternatives

Sematext is a SaaS platform that offers log management, system monitoring, real user monitoring, synthetic monitoring, and distributed tracing.

In this review, we will look at the features of Sematext and why you would use it.

Sematext isn’t the only log manager or system monitoring service on the market. So, we will also be examining some of the rivals to the business, focusing on those alternatives that deliver log management and analysis.

About Sematext

Sematext Group started in 2010 as a consultancy, originally called Sematext International. It was founded by Otis Gospodnetić in Brooklyn, New York, where it is still headquartered, and its founder still leads it. Gospodnetić became an authority on Apache Solr and Apache Lucene, which are two open-source search platforms. Sematext was created to help businesses adopt these technologies, and the company also gained expertise in Apache Mahout, a machine learning system, and Nutch, a Web crawler.

Sematext Monitoring was launched in 2013, exploiting Solr and Elasticsearch to explore system data and interpret live status reports into dashboard output. Essentially, this service behaves like a log message server, and so it wasn’t unexpected when the company produced Sematext Logs in 2014. In addition, distributed Tracing was added as a service in 2015.

Sematext moved its software to the Cloud in 2017, delivering it in the SaaS model. In addition, the company’s latest modules were added to the SaaS platform in 2019 and 2020. These are Sematext Experience, a real user monitoring service for Web pages, and Sematext Synthetic Monitoring, which is also aimed at monitoring the performance of websites.

Sematext Logs

Sematext Logs

The Logs module is probably the company’s most successful package. This is a hosted implementation of the ELK Stack. ELK is the group of services produced by Elastic BV in the Netherlands. The stack includes Elasticsearch, a data search engine, Logstash, a log file collector and parser, and Kibana, a Web interface for statistical analysis packages. The three elements fit together to create a suite of log management and analysis services.

Elastic BV released ELK to the public for free. However, the company charges for a SaaS version of the suite. In this, Sematext presents direct competition because Sematext Logs is precisely the same thing.

ELK is a great tool. However, it is a framework, and you still need to set up log collectors on your site and upload those messages to the Sematext server. The Sematext dashboard includes a free library of third-party agents that you can download and install. However, it is still up to you to set up those systems.

You need to create your queries to sort through all of the logs and work out how to feed those through to widgets in Kibana to get meaningful data shown on the screen. Once you have mastered selecting specific information from logs as they pass through the Logstash server, you can quickly learn how to look for security breaches and activity anomalies.

Sematext Infrastructure Monitoring

Sematext Infrastructure Monitoring

Sematext Infrastructure Monitoring places performance thresholds and resource utilization notification levels on gathered system metrics. So, if a problem starts to develop, that marker gets triggered, and an alert is generated. Getting alerts forwarded to essential technicians by email or Slack message means that IT operations staff don’t need to watch the system monitor’s dashboard all of the time. Instead, thresholds should be set at levels that allow technicians time to deal with the problem before it becomes noticeable by the users.

The Infrastructure Monitoring service watches over the performance of servers, applications, and services, such as virtualizations and Web servers. It doesn’t cover network performance. Instead, the system will track issues with databases, containers, and Java applications (through JVM). It can also reach out and collect statistics from Cloud platforms, including AWS, Azure, IBM Cloud, and Google Cloud Platform. It can fetch data from the iOS and Android mobile platforms as well.

Endpoint monitors in the service can collect data from Windows, macOS, and Linux. You can also get status data directly from the major Web browsers, and the system will scan devices for software and work out an applications dependency map.

Sematext Experience

Sematext Experience

Sematext Experience is an absolute user monitoring service. This tool can exercise interactive elements in a Web page to ensure that it works appropriately while running live. The module also gathers performance data on pages as they are delivered to each visitor. You will get alerts if errors occur in delivery or loading.

This tool records actual events in the website’s life.

Sematext Synthetic Monitoring

Sematext Synthetic Monitoring

Accurate user monitoring can be expensive, and many of the stats you want to know about your website’s performance can be gathered through automated tests. This is the service offered by Sematext Synthetic Monitoring. The tool sends out requests for pages and checks on their delivery speed and load times. Tests can be launched from several points around the globe so that you can keep informed about your site’s availability to all users wherever they are.

Tools in this package include SSL Certificate monitoring with alerts on verification problems. You will also get traces on HTTP, DNS, and file transfer protocol issues.

Sematext Tracing

Sematext Tracing

Sematext Tracing service follows distributed applications and microservices, using telemetry to record resource usage and performance of those interdependent functions and offloaded services. In addition, the system uses the OpenTracing protocol to catch debug messages from impenetrable functions and API backends as they run.

The Sematext Tracing service will generate an application dependency map that exposes the supporting services for each API and front-end module, drilling down recursively to find services that support services. The package has powerful tracing capabilities for code written in Java. This service is bundled in with the Sematext Infrastructure Monitoring package.

Sematext deployment options

Sematext is primarily a cloud platform. However, it is also available as an on-premises software package, called Sematext Enterprise, if you would instead host the system yourself. The software runs on Docker containers.

Sematext Enterprise doesn’t include Sematext Synthetic Monitoring. However, all of the other modules are available for on-premises installation.
