System Requirements

Operating Systems and Admin Rights

The program is completely functional under the 32- and 64-bit operating systems Windows XP/2003/Vista/2008/7/8.1/2012/10/.

All services are available to users who have the domain administrator privilege.

The program requires the local administrator rights. It is not recommended to use admin accounts with empty password.

The following services are not available to users who have the local administrator and domain user privileges:

  • Retrieving information from remote computer.
  • Remote computer shutdown.

The following services are not available to users who have the local user and domain user privileges:

  • Remote computer shutdown.
  • Permitting and denying access to this computer's files and folders.
  • Monitoring and controlling shared resources usage by network users (active connections).
  • Getting information on remote computer's user, domain, server, OS, time.

Please note, that NetBios, ICMP, TCP, UDP should be enabled in your firewall.

Correct operation of the program is not guaranteed under Windows 95/98/ME.

When you use monitoring checks that connect to remote TCP ports, please remember about the TCP opened ports scanning limitation under Windows XP and some other versions of Windows. There is a limit of 10 allowed simultaneous outgoing half-open TCP connections. When you hit the limit, the system holds new connections. The program performance can suffer and monitoring results can become wrong. Learn more about the TCP limitations.

 

Hardware Requirements and Performance

The hardware requirements depend on the number of hosts you are going to place on the network map and monitor (the background program performance depends on the number of monitoring checks and the time interval between the check attempts).

The following characteristics are the minimal hardware requirements for the most popular checks for the ICMP, SNMP v1, 2c protocols:

  • CPU: x86/x64 1 GHz. Multiple core CPU is better for monitoring.
  • RAM: 2 GB.
  • Disk Space: 100 MB is bough for the program installation. Storing the monitoring statistics and check results in the program's internal file database requires more disk space. We recommend having at least 2 GB of disk space for it. Storing a result of one polling of one monitoring check takes 40 bytes of memory. If the check time interval is set to 1 minute, this check will generate 60 KB of statistics per day. Multiply this on your number of checks and days you want to store the results for analysis.
  • The Internet is required for the program activation and checking for updates.
  • Minimum screen resolution is 1200x800.
  • A web browser is required for the web UI operation. Google Chrome 40 or higher, Firefox 35 or higher, Internet Explorer 10 or 11 are recommended.

If you plan to work with big network maps, we recommend a more powerful PC. The minimum PC described above will work quite slow with the 1000-host map. This limit is also actual for virtual machines. We recommend to use a dedicated powerful server for working with big network maps and monitoring hosts placed on them. We also recommend you to spread hosts over several maps if you have too many hosts on your network. The recommended number of hosts for one map is 200.

The maximum number of monitoring checks the program can deal with depends on the computer hardware configuration and the check type. Some types of checks consume more resources than others.

  • ICMP, SNMP v1,2c, ARP, HTTP, file checks - these types take less resources. An average PC can handle up to 10,000 checks with the 30-second interval.
  • SNMP v3 checks can generate more than 40 network requests per second. An average PC can handle up to 5,000 such checks with intervals larger than 60 seconds. The CPU load will be more than 50% on the 2-core 1 GHz CPU.
  • WMI checks take a lot of system resources. We do not recommend you to create more than 200 WMI checks with intervals less than 30 seconds or 1,000 checks with intervals less than 150 seconds, etc.

We do not recommend adding more than 10,000 checks to one host.

For the successful network topology discovery and drawing connection links between switches and other devices, it is necessary that you have managed switches with SNMP or LLDP enabled on your network.
