Q330 SeisNetWatch Agent Released

 March, 3^rd 2005

ISTI announces the availability of a Quanterra Q330 agent for their SeisNetWatch (SNW) state of health monitoring system. The Q330 agent compliments the existing suite of state of health (SOH) agents previously released.

This new agent monitors the Q330 via the Ping Status packets, allowing one to monitor the devices without the need to register directly with the Q330.

Once the applet loads and connects to the server, you can view the station details.

To view the instruments being monitorred via the Q330 agent, The easiest thing is to subset the display for the Transportable Array. Click on the "Subset" tab, and then click on the dropdown selectors for "Network equals ZZ" and hit the submit button. (ISTI is using ZZ internally as our own network ID).

a new subset view for ZZ will be created. Click on either of the 2 stations to view the details.


The agent can display information in either a normal or verbose mode. The display updates from the server every 5-6 seconds. The agent queries the Q330s and updates the server at a rate configurable by the administrator on a station by station basis.


Each station has the following information that is currently being used for voting.

• Seconds since last packet received
• minutes since loss of GPS signal
• Input 1 (used by USArray to sense water in the vault, should always be 0)
• Mass Position 1
• Mass Position 2
• Mass Position 3
• Ethernet Checksum errors

This test server is configured so that you can only view the history information for the parameters that are voting (ones with a colored circle to their left). If you click on the tiny plot icon, the program queries the server for available historical information, and once it returns, just click on "plot" to see the graph for the default amount of time.

In general I can modify the information reported and how it is reported. Most users want certain parameters to be voting and specially configured voting levels for each station. That is a central server function and is part of our normal installation for the end users.
