2.1 Change Monitoring Dashboard Performance

The Chart view might take about 25 seconds to load events up to 500,000, while the Grid view might load in five seconds with a similar number of event. Any operation, such as grouping and sorting, with events upto 500,000 events on the Grid view might take about 40 seconds to process and display.

If there are around 500,000 to 1,000,000 events, the Chart view loads in a minute, and the Grid view loads in half a minute. Any operation on the Grid view with around 50,00,00 and 10,00,000 events might take one and a half minute to process and display.

Similarly, if there are 1,000,000 to 1,500,000 events, the Chart view takes about a minute and a half to load, the Grid view takes about half a minute to load, and operations on the Grid view takes about two minutes to process and display.

2.2 Performance of Single Change Guardian Agent

Following are observations about the events generated per second from Change Guardian Agent for Windows and Security Agent for UNIX:

The EPS count might vary with an increase in time interval and increase in the number of events generated in one burst.
EPS count depends upon the number of files present in the folder if the folder is monitored for file integrity.
EPS count might vary with the hardware configuration of the agent machine.
EPS count might vary when the agent is monitoring a combination of assets, such as Microsoft Windows and Active Directory, or Active Directory and Group Policy, or Active Directory and file integrity.
