  • As of now we support Windows 2012 R2 and above.
  • For exceptional cases, we have kept backward compatibility for MS NetMon use case, which can be enabled at discover service windows level, to enable this mode a service restart is needed. detailed steps to enable this backward compatibility mode will be documented separately.
  • Benchmarking and load testing for ODWinNetMonNative.exe
    

  Users	Netwatch run Time in min	Request Per Sec or Min	Number of IPs from where the request are sent	RAM Utilization (MAX in MB)	CPU Utilization	ETL/CapExp_Ready Size	Windows Version	Memory	CPU
  500	10	~610 requests per seconds	715	less than 10 MB	between 5-50%	~500-512 MB	Windows 2016	8	2
  500	10	~649 requests per seconds	715	less than 10 MB	between 5-50%	~400-512 MB	Windows 2012 R2	8	2
  500	10	~619 requests per seconds	715	less than 10 MB	Between 1-20%	~512 MB	Windows 2019	8	2

  • Note: This benchmarking is only for ODWinNetMonNative.exe and not for supporting utilities used in the background from Microsoft.

• Linux NetWatch

  • Using native linux capabililties monitor the network IO (No additional installation required)
  • This will also co-relate the data with process performing the network IO
  • Official benchmarking is to be done, thus this feature should be used under supervision, not recommendded to be run on production setups.

• NetWatch Limitations

  • This feature monitors the network IO, and will have additional overhead on the system.
  • it is recommended to run this setup under supervision with a conscise choice
  • It is recommended to avoid running netwach on domain controllers, citrix servers, API Gateways, Firewalls, etc.
  • The intended use case of netwatch is to identify the network relationships of Hosts and Applications on those hosts. Thus it should be run on expected hosts under supervision.

Upgrades

• It is recommended that any version of ch-rel-2.0.0-* or less should be upgraded to this version.
