[FAQ-1155] Status page - 'Senders' report on feed site / scanner performance



The status page for a hub includes a detailed report on the performance of scanners and other audio sources. This document provides information describing the information presented in this report.


Key information is written in bold, and information rarely significant is written in gray.
The senders page itself lists information for all Rangecast feed site senders connected to the hub. For more compact information about a single sender, the Overview page rectangle representing each sender links to a version of this page showing only information about a single sender.


The first section of the Senders status page is the "Senders List", which summarizes the operation of each Rangecast sender within the hub. Here is a description of each field in this table:


The second section of the Senders status page is "Sender Alerts", which lists each error currently being reported by a Rangecast feed site.An error in this list may not mean that there is a current problem. In many cases, a transient error condition will be reported for up to 24 hours, so intermittent issues may be recognized and corrected. This section is omitted if there are no errors. For each error, three pieces of information are provided:


The third section of the Senders status page is "Sender Metrics", which provides data about the performance of each scanner or audio source. The default presentation is sorted by time and reports information from all senders over the past two hours. An alternate format sorts by sender ID and allows for direct comparison of data from the same sender in different hours.

At the end of the page, there is a link to a "full sender report" that expands this table to show data over the past several days.


The fourth section of the Senders status page is "Cluster Metrics", which uses the information from the previous table (performance metrics) to calculate overall performance of each group of scanners operating co-operatively through Multisync.


The fifth section of the Senders status page is usually suppressed, but is visible if pressing the "full sender report" link. This is a table showing when Rangecast feed site senders were launched and when they were last active, in effect documenting the extent of each application session. This table is useful for observing when a sender has been active, when it has launched, and when it has been offline.


In the first table (Rangecast sender list), the LAN address may be a link to a report about the configuration and environment of the feed site PC. If clicked, this information is shown between the first and second tables, in a special section titled "File View from Feed Site PC" (and identifying the PC by WAN/LAN internet address.) The report is broken into four sections:

The fourth section is a log of PC operational history and lists recent events in the operation of the Rangecast watchdog process. All clock times are reported in the PCs local time zone while status page reports are in Eastern Time, so be aware of the possible time zone difference. These entries do not relate to specific scanners, but the PC as an element in Rangecast. Each time the Rangecast software is launched, the watchdog is given a pseudorandom identifier which is shown on these lines, so it is possible to identify when the software was restarted. Line types include:

The watchdog ID (reported on config/launch lines), in the last field, record how the watchdog was launched. These codes:
