Devmst is a program that generates the HTML code that displays the most
current graphs for each monitored interface for that device but without any
statistics. devmst takes one parameter, the sysName. Devmst reads the
sysName.mst file and generates a graph for each instance or group it finds in
the file. If needed, the RRDs are updated from NetView's snmpCollect directory
and then the most recent detailed graphs are generated for each
interface/instance or group. The lines within sysName.mst then determine what y
legend, labels, titles and threshold values are used.
devmst generates HTML that is dependant on the environment it is run
within. I.E. if it is run from a web server or not. If run from within the web
server by the user selecting a hyperlink, then the resulting page will contain
further hyperlinks that will cause devdtl to execute for detailed views of the
interface. If devmst is not run from within the web server, devmst generates
HTML that has static links to other HTML pages that the user can generate by
running devdtl and saving the output. Using this combination allows HTML and
graphic files to be exported or moved to other systems for later display. The
graphic images are stored in separate files within the web server's OverTime
directory under another directory that is also called the same as the sysName.
