A common task for every SNIP operator is to check on who may be using your machine. This information is provided in a simple report you can access from a button on the Clients and Caster tab. This article describes the general topic area of managing your users.
The report which SNIP provides of your currently connected users has been enhanced in a few simple ways. These were requested by operators who allow multiple connections from the same account.
- You will now see a list of all the current mountPts that any user account is connected to.
This is of value to see what accounts are using your services the most.
- You will also see the last NMEA-183 $GPGGA message the client has sent (if any).
This is of value to some operators who wish to track their user’s locations.
- The $GPGGA message is translated into LLH and the distance to the Base station is shown.
The textual report will still show how much data has been sent to each user and for how long it has been connected. When operating in the autonomous mode (no user ID required) the report shows the IP:port used for the connection.
The report itself has been slightly restructured to present this information in a more readable way. Here is an example of a report of connected users:
The following registered users (of 3 total users) are connected at this time: User: User1 with 4 connections. [ gisar30, RTCM3EPH, SCSC02, SCSC02 ] User: User2 with 4 connections. [ gisar30, RTCM3EPH, SCSC02, RTCM3EPH ] User: user with 1 connections. [ SCSC02 ] There are 11 users in the Table of Registered Users. There are currently 9 connections which are feeding data to these remote points: MountPt: RTCM3EPH 188.8.131.52 : 55949 User2 Sent: 1.030 MB Over: 16:06.617 minutes MountPt: RTCM3EPH 184.108.40.206 : 63193 User1 Sent: 1.459 MB Over: 22:48.490 minutes MountPt: RTCM3EPH 220.127.116.11 : 59917 User2 Sent: 1.427 MB Over: 22:15.018 minutes MountPt: SCSC02 18.104.22.168 : 55948 User2 Sent: 314.01 KB Over: 16:06.620 minutes MountPt: SCSC02 22.214.171.124 : 63195 User1 Sent: 443.89 KB Over: 22:47.190 minutes MountPt: SCSC02 126.96.36.199 : 64017 user Sent: 451.17 KB Over: 23:07.109 minutes MountPt: SCSC02 188.8.131.52 : 59915 User1 Sent: 433.51 KB Over: 22:15.019 minutes MountPt: gisar30 184.108.40.206 : 63180 User1 Sent: 674.29 KB Over: 22:58.981 minutes At location: $GPGGA,195314.13,3407.6618442,N,11749.5264569,W,1,00,1.0,284.697,M,-33.512,M,0.0,*7B MountPt: gisar30 220.127.116.11 : 59916 User2 Sent: 650.98 KB Over: 22:15.018 minutes Regarding the counts shown for data sent to a connection, keep in mind that any given user may have connected more than once.
Note that in the above connection from User1 originating from xx.xx.31.227, the NTRIP Client is periodically sending $GPGGA sentences, and the last sentence received is being displayed.
- Use the “List Current Users…” button (found on the Caster and Clients tab) to see information about your current users. This data is sorted by mountPt (streams) and the users which are connected to each.
Useful to learn which mountPts and users access your SNIP node the most often.
- Use the “List Recent IPs…” button (found on the Caster and Clients tab) to see information about what IPs have been used to access your system. This data is sorted by IP used and user account (if any) and provides data on the number and length of the connections. The most frequent connections are then summarized, often these are NTRIP Clients who are experiencing connection issues.
Useful to learn who attempts to access your SNIP node the most often.
- Use the “List MountPts” tab (found on several tabs) to see information about your current data streams.
Useful to learn the current connection state of all data streams offered by your SNIP node.
You can also use SNIP‘s map graphical display style to see where any connected users are located. This feature will plot the last $GPGGA sentence from all users and, if the display is left open, update these values as new NTRIP Client data is sent in (producing a breadcrumbs trace o the Rovers movements). Those users who do not send $GPGGA sentences are plotted at zero/zero.
