httpcollector rrd and graph

[Chong Zhang]

Hi all,

I followed the http collector example and have a few basic questions:
. How/where I can look at the graph?
. Does it create one jrb file per attribute? Can I create one with multiple DS?
. In the snmp-graph.properties, how are those {rrd1}, {rrd2}, {rrd3} defined?

TIA,
Chong

you have to define a graph definition to make it viewable in the WebUI.

I guess the example from the OpenNMS Wiki

        http://www.opennms.org/wiki/Monitoring_Apache_with_the_HTTP_collector

can clearify some things. I hope it helps

The {rrdx} thing threw me off, too.  The explanations are in the middle
of the snmp-graph.properties file although it is not terribly clear:

# values available to prefab reports:
# {rrd1}, {rrd2}, {rrd3}, ...  must match the datasources exactly
# {startTime}, {endTime}
# any external values specified per report
