A second very important upgrade principle is that any modifications and customizations to the system made by the local staff must be extracted and moved into the new version. These monitors provide a way for forecasters and technicians to track data ingest and restart subsystems if necessary, in most cases without having to call on outside help. Using World Wide Web technology, a script runs every ten minutes on the data ingest machines to collect information on the timeliness and completeness of some 40 datasets, and then to build a set of Web pages to present this information to the viewer. In the example here, a caution symbol is seen on the Point Data link. This may be due to a problem with a decoder or a data ingest process at the local site, a failure somewhere in the data distribution system, or lack of data at the source.
Data monitor summary page.
Since there are over two dozen ingest processes, distributed among three processors, a summary mechanism is used, just as for the product monitor. Note also that a similar appearance is used, with both color and icon indicating the process state. Ingest process monitor. Users can also review an on-line log from this monitor. Information from the monitors is automatically forwarded to the NCF, where operators are able to perform more extensive trouble-shooting of the ingest and data storage systems.
