NAME
|
|
ntpa - NTP Analyzer daemon program
|
|
|
|
SYNOPSIS
|
|
ntpa --config file [--temp path] [--writepid file] [--daemon name]
|
|
|
|
DESCRIPTION
|
|
The ntpa daemon is the core process in the NTP Analyzer system.
|
|
ntpa(8) is responsible for collecting data from NTP daemons. Data are
|
|
collected using ntpq(8) and ntpctl(8). The ntpa daemon also generates
|
|
graphs and web pages and perform other tasks like sending status mails.
|
|
|
|
The graphs and HTML files generated by ntpa are placed in the ntpa www
|
|
directory and can be presented by any web server. Additional JavaScript
|
|
and CSS files are also located in the ntpa www directory.
|
|
|
|
NTP Analyzer uses the Twitter Bootstrap and the jQuery framework to
|
|
make web pages responsive. Pages can not only be viewed on traditional
|
|
PC screens but also on mobile devices.
|
|
|
|

|
received since reset are signed 32 bit and overflows are not handled.
|
|
Values above 2,147,483,647 are shown as 0.
|
|
|
|
When a host page is configured to be shown in UTC but data was recorded
|
|
in local time graphs and time stamps mismatch. The same applies for
|
|
host pages shown in local time but data is recorded in UTC.
|
