EventLog Analyzer System Requirements

This section lists the minimum system requirements for installing and working with EventLog Analyzer - Distributed and Standalone editions

Hardware Requirements

Minimum hardware requirements:

  • Dual-core processor.
  • 2 GB RAM.
  • 50 GB hard disk space for the product.
  • 1024x768 display resolution.

Ideal hardware requirements:

  • Quad-core processor.
  • 6 GB RAM.

Event handling capacity:

Provided the minimum hardware requirements are met, a standalone installation of EventLog Analyzer can handle log rates, or events per second (EPS), as given below:

  Average log size Average EPS Peak EPS
Syslog 100 bytes 20,000 25,000
Windows event log 2 KB 2,000 2,500

To enhance the events handling capacity, a distributed EventLog Analyzer installation with multiple nodes can handle higher log volumes.


  • The number of processor cores determines the indexing and search performance of the installation. More the number of cores, better the performance of the tool.
  • It is recommended not to allocate more than 32 GB of RAM to a single instance of the EventLog Analyzer Server.

Customer Speaks
  • Credit Union of Denver has been using EventLog Analyzer for more than four years for our internal user activity monitoring. EventLog Analyzer provides great value as a network forensic tool and for regulatory due diligence. This product can rapidly be scaled to meet our dynamic business needs.

  • The best thing, I like about the application, is the well structured GUI and the automated reports. This is a great help for network engineers to monitor all the devices in a single dashboard. The canned reports are a clever piece of work.

  • EventLog Analyzer has been a good event log reporting and alerting solution for our information technology needs. It minimizes the amount of time we spent on filtering through event logs and provides almost near real-time notification of administratively defined alerts.

  • I love the alerts feature of the product. We are able to send immediate alerts based on pretty much anything we can think of. We send alerts when certain accounts login, or when groups are changed, etc. That has been very helpful. Also the automatic archive of the log files has been very helpful and has taken the worry out of keeping old logs. The “Ask Me” function is very nice as well. It is great to have some natural language queries built in where you can just click a button and get an answer.

  • Windows Event logs and device Syslogs are a real time synopsis of what is happening on a computer or network. EventLog Analyzer is an economical, functional and easy-to-utilize tool that allows me to know what is going on in the network by pushing alerts and reports, both in real time and scheduled. It is a premium software Intrusion Detection System application.
