Is there a limit to the number of paths I can add to a device?
There is no hard limit to the number of paths you can add to a device.
We have seen minor performance degradation as the number of paths increase. However, this is unlikely to affect performance when probing up to 20 paths.
What is the resource impact on the device when running paths?
Current testing indicates that the NetPath agent uses 60MB of RAM, negligible network bandwidth and less than 300 MB drive space. CPU performance is dependent on the number of configured paths and is expected to run at less than 5-25% of available CPU resources.
How do I install the NetPath agent?
There is not a separate enable NetPath option. The NetPath agent automatically installs the first time a path is setup on a Device. Please see NetPath Agent Installation for further details.
Which version of .Net is required?
At least .Net 4.5 is required for NetPath. Where this version is not installed on the device, it is automatically deployed by the NetPath Agent.
What is the NetPath agent Windows service name?
The NetPath agent service is called AdvancedMonitoringNetpathAgent. This service starts automatically and restarts on a failure (2 times).
Where does NetPath install to?
By default installs to the following locations:
Which ports and protocols does NetPath use?
- ICMP over type 11 to discover network paths, must be allowed inbound to the device running the NetPath agent.
- TCP over the entered path port to discover the service status
- TCP over port 43 to query IP ownership and other information about the discovered IP addresses, must be allowed outbound from the device running the NetPath agent.
Is NetPath available for workstations?
NetPath is available for Windows servers and workstations running Advanced Monitoring Agent version 10.7.1 (or later).
Is there a particular library NetPath utilizes?
NetPath uses WinPcap, a Windows packet capture library.
Can I restrict who has access to NetPath on my Dashboard?
NetPath access is limited to those users with NetPath (Usage and/or View) Roles and Permissions enabled.
I cannot add identical paths to a device!
Paths must be unique. Identical, duplicate paths (including ports) on the same server are not supported.
Can I set my own status thresholds for the network path?
Although we recommend dynamically generate (which harnesses NetPath technologies to analyze the path statistics for each interval and set the appropriate threshold levels) we have included the ability to set your own status thresholds. Choose custom during path creation and enter the warning and critical levels for both the Endpoint Latency Threshold and Endpoint Packet Loss Threshold.
How long is the network path’s data stored for?
The last 30-days data is available (depending on when the path was added) and can be viewed in the Path History chart.
Are policies available for NetPath?
NetPath does not support polices, individual paths are added for each device.
Will I receive a notification when a problem is detected with the path?
By default, a NetPath Check is added for each path. Depending on your configuration, a notification (email, SMS, PSA ticket) is generated when the Check fails and subsequently passes.
I have a red 'No Data Found' message box displayed on a map. What causes this?
This indicates most current time interval is not populated with data. The probe may be actively running or there may be a gap in the data. Select one of the green bars in the bottom path history chart to display the most current, complete map.
If the NetPath agent network is down, is this displayed on the Monitoring and Management Dashboard?
Where the NetPath agent cannot communicate with the cloud service, this is only reported in the NetPath section (a gray tab in the Path History chart). It is not displayed on the Dashboard.
I probed a destination over a VPN connection, but it does not return all the expected hops. Is this expected?
Yes, paths executed over a VPN connection may show a small number of hops which is not representative of the true internet path.
Can I delete paths? How do I uninstall the NetPath agent?
Paths are removed from the NetPath section and when all paths are deleted for a device, its NetPath agent is uninstalled. Please note, deletion is a non-recoverable action that removes both the path, its associated history and NetPath Check. Please see: Remove a Network Path and Deactivate NetPath for further details.
