Editing a probe

Hovering over the desired probe highlights it in blue. The probe <Edit> icon at the upper-right of the page opens with four options: <Probe>, <Streamer>, <NTP service> and <License>.

Edit probe: Probe section

The probe section is divided into three subsections: “General”, “Probe information” and “License information”.

General: Configurable probe fields

This subsection allows you to rename the probe, assign it to a different group and specify the LAN and WAN IP addresses of the probe server. Use the <Probe group> dropdown to assign the probe to a different group. If you want to assign the probe to a new group, you must first create an empty group using the dashboard.

The probe name was created by Volicon Media Intelligence service Support when the probe was initially created and cannot be changed by the customer. To change the probe name seen by users, edit the “Display name” entry.

The probe IP address is normally set statically, but, optionally, dynamic addressing may be used via DHCP.

Probe status information

This is a read-only status display.

Figure: Accessible probe information display

If the probe is not accessible, the date of the last keep-alive is displayed.

Level license info

The bottom-most section is also read-only and displays licensing information.

Edit probe: Streamer section

The “Streamer” section allows you to change the IP port values used to stream video. These should normally be left in their default settings.

Edit probe: NTP service section

Accurate timing is critical for successful Volicon Media Intelligence service operation. Many aspects of Volicon Media Intelligence service require millisecond-timing accuracy. This section allows you to change which network time protocol (NTP) time server Volicon Media Intelligence service uses and how often it is polled. Volicon Media Intelligence service defaults to the Microsoft NTP server defined in Windows.

In some cases, this setting is locked by Volicon Media Intelligence service. In that case, settings are read-only and appear to the right of the polling interval and server.

1. If you run an internal corporate time server, change the configuration to point to it.

2. Another option is to use an NTP server pool. This has the advantage of redundancy, in which you can select geographically nearby servers to minimize transit time latency. The NTP Pool Project is popular and can be found at http://www.pool.ntp.org/en/.

3. A third option is to use the Windows operating system as preconfigured, pointing to the public Microsoft NTP server: time.windows.com.

Poll interval: This setting is only active if the SpecialInterval flag is set.

Set the polling interval value to an integer and select the units from the <Interval> collection. Volicon Media Intelligence service recommends setting the polling interval to 3600 seconds.

NTP server

Enter the URL or IP address of the desired NTP server. Add additional servers for redundancy. If the active server throws an error or does not respond, Volicon Media Intelligence service will automatically switch to the next server on the list.

NTP flags

In general, use the system defaults when adding NTP servers, unless instructed otherwise by Volicon Media Intelligence service support.

Table: NTP flags

SpecialInterval	Normally W32Time (Windows Time service) will poll the remote NTP server on a floating interval based on the quality of the time samples being returned. Setting the SpecialInterval flag changes this behavior to a fixed static interval. Use the polling interval section to set the interval.
UseAsFallbackOnly	Setting this flag tells the time service to try the other time servers before using this one.
SymmatricActive	The host sends periodic messages regardless of the reachability state or stratum if its peer. The host announces its willingness to synchronize and be synchronized by the peer.
Client	The host sends a request to the NTP server and expects a reply at some future time. The host announces its willingness to be synchronized by, but not to synchronize, the peer.

Once the server and flags are selected, use the <Add server> button to add the new NTP server. To delete a server, use the <Delete> button.

Edit probe: License section

This read-only section displays each licensable feature and, where applicable, how many instances are allowed. Each feature consists of three entries: allowed, configured and running.

• Allowed indicates the maximum quantity authorized by the license. In instances where the feature is selectable to be either enabled or disabled, its corresponding value will be displayed as YES or NO.

• Configured indicates how many instances are currently configured.

• Running is a real-time display of the status of each feature.
