EventLog Analyzer Performance Optimization Guide

 

System resources calculation

Hosting EventLog Analyzer without adequate system resources may affect its ability to perform necessary tasks. Use the calculator below to approximately determine the hardware you’ll need for EventLog Analyzer to perform smoothly.

System resources optimization 

 

Disk space 

(a) Log volume-based optimization

The hard disk space required depends on the log volume generated in your environment. For a high log flow rate, you need to have a larger disk space to store and process the logs. However, if the need for disk space is growing at an alarmingly rapid rate, you should check if only the required logs are being collected. Making the changes below can reduce the need for disk space without compromising security.

  • Disable auditing of irrelevant Windows events.
  • Ensure that only the necessary syslogs are forwarded to the server. 
  • Employ log collection filters to remove noise.

(b) Retention-based optimization

The log archive and index folders are the main contributors to the growing size of stored logs. The total disk space required at any time to store the logs generated by your network is the combined size of the archive and index folders.

  • Archived data: The archived index slows down the search function but occupies less disk space.
  •     
  • Indexed data: The raw index speeds up the search function but occupies more disk space.

The archive and index sizes for a specific time period depend on the total volume of raw logs generated during that time period. 

  Default location Default retention Retention settings Compression
Indexed data <Installation folder>/EventLog Analyzer/ES/ 32 days To update or change the retention period, navigate to Settings → Admin → Database Retention Settings. Data which is older than 32 days will be automatically compressed in the ratio of 1:10.
Archived data <Installation folder>/EventLog Analyzer/Archive/ Forever To update or change the retention period, navigate to Settings → Admin → Archive Settings. Data which is older than a day will be automatically compressed in the ratio of 1:20.
 

CPU and RAM

CPU: The need for CPU power depends on the log volume, existing alert profiles, and correlation rules in place. If CPU usage is abnormal, do the following:

  • Set up policies to forward only the required logs. 
  • Review and ensure that only the required alert profiles and correlation rules are in place.

RAM: Correlation is a RAM-intensive process, so make sure that only the necessary correlation rules are in use.

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.
    Benjamin Shumaker
    Vice President of IT / ISO
    Credit Union of Denver
  • 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.
    Joseph Graziano, MCSE CCA VCP
    Senior Network Engineer
    Citadel
  • 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.

  • 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.
