Notes on Each Graph:
System HTTP/S Throughput. This graph shows all the HTTP or HTTPS (e.g., HLS)
traffic that is going through the caching engine. These numbers are 5 minute averages and
samples. Snapshots of additional current measures are provided on the right hand side.
There are three controls related to this graph:
•
Services View / Hardware View . This will switch the view of the graph to display
either the streaming services bandwidth, or to view bandwidth by NIC (network
Control Description
Clicking the
Gear
icon toggles the display of the bottom axis
for each graph as well as the legend (which are both off by
default.) Once displayed, clicking on the Data set names
within the Legend will toggle its display within the graph.
The
Show
drop-down allows you to pick the number of days
to display. This displays today or up to the last N days. In this
way, smaller more pinpointed views can be generated.
The
Display Timezone
button displays the current timezone in
UTC. It will be of the format UTC+#### or UTC-####,
where #### is the displacement in hours off UTC. Clicking
this button toggles between the DME's native timezone and
UTC+0000. Only the dates on the graph will change if
displayed. Toggling the timezone is handy when comparing
graphs from multiple DMEs in different timezones, as all can
be normalized to UTC+0000 and provide direct time
comparisons. This relieves the need for the addition and
subtraction previously necessary.
The
Download CSV
button is for advanced users who wish to
chart or investigate information offline. This downloads a file
(named DMEStats-<<DATE>>to<<DATE>.csv) of all the
measurements within a comma-separated-values format –
easily imported into common spreadsheet programs. This may
take a moment for the DME to generate and download, so
please be patient. Each of the columns is labeled and
represents a 5 minute average measurement. Note: cpu_time is
not an average, but a snapshot measurement. Definitions of
the included data can be found in
"Squid: The Definitive Guide"
at https://www.amazon.com/Squid-Definitive-Guide-Duane-
Wessels/dp/0596001622 or via PDF off the Internet. Again,
remember that the data is only kept for two weeks, so please
download accordingly.
