NetVoyant is an SNMP poller that provides information about the infrastructure between the servers and the end user. The most important feature that will be used is the tracking of interface statistics on routers and switches comprising the network between the servers and the users. NetVoyant also has the ability to retrieve IP SLA test results.
See this document for practices that should be implemented when deploying any of the NetQoS products.
The appliance can be run in a virtual environment as it does not require any specialized hardware. CA has only recently begun supporting NV installed in a virtual environment; as such, there are no specific recommendations for installation in a virtual environment. The following are the hardware specifications of the hardware CA usually sells with this appliance:
- 2.5 GHz Quad Core processor
- 3 GB RAM
- 300 GB hard drive space, partitioned into a C: (system) drive of at least 20 GB, the remainder into a D: (data) drive.
- 1 Ethernet LAN port
- Windows Server 2008 R2 or Windows Server 2003 64-bit or Windows Server 2003 Web Edition or Windows Server 2003 Standard Edition
- Internet Explorer 7 or 8 (32-bit version recommended) or Mozilla Firefox version 3.5 (later versions not supported)
- IIS v6.0
- ASP.Net v3.0
Tips and Tricks
Build Datasets Setup Auto-Discovery rules in favor of Auto-Enable rules (why discover something if you're not going to poll it. In most cases, Discovery rules are better since they prevent undesirable poll instances from taking resources on the server.)
Build Custom Views
Tweak Discovery - Make sure you disable any classes you don't want to monitor and that you have setup your discovery rules.
Ports to open (firewall rules)
- NetVoyant uses ICMP and SNMP to communicate with devices it monitors. As such, bidirectional ICMP and bidirectional SNMP should be allowed between the appliance and the device(s) to be monitored. The device(s) must also be configured to allow SNMP polling by the appliance. Configuring traps to be sent from the device(s) and the appliance are optional and not required.
- NV 7.1:
- TCP 80 - Web service (default)
- TCP 900 - Names service
- TCP 3308 - MySQL
- TCP 9601 - mibs.exe
- TCP 9602 - topology.exe
- TCP 9603 - polls.exe
- TCP 9604 - pingsvc.exe
- TCP 9605 - traps.exe
- TCP 9606 - notify.exe
- TCP 9607 - Serviced.exe
- TCP 9608 - Names service
- These are the same across all versions:
- Each Server Outbound: TCP 25 - SMTP Email Reports
- Each Server In and Outbound (bidirectional to/from all monitored devices)
- UDP 162 - SNMP Traps
- UDP 161 - SNMP to monitored devices
- Administrator to Each Server (Optional):
- TCP 5800 (VNC)
- TCP 5801 (VNC)
- TCP 5900 (VNC)
- TCP 5901 (VNC)
- TCP 3389 (Remote Desktop)
Default MySQL Database Passwords:
The appliance should have DNS servers and an NTP server configured. DNS name resolution assists in the analysis and interpretation of reports. Internet access on the appliance is preferable to facilitate installation of the NetQoS components.
