Hi,
We are using XML collector for datacollection from hitachi devices.
Collection interval is 5 minutes. Device generates xml file every 5 minute.
Opennms uses SFTP to load xml files from device and parse those files for
counter values, store in JRB/RRD files every 5 minutes.
But the problem is opennms is taking more than 5 minutes to parse the data
if the data is huge ...and missing some polling intervals.
say datacollection starts at 10:00 AM
and completes at 10:08 so the next poll interval will be at 10:10 in this
10:05 poll cycle is missed that means file generated at 10:05 in device is
not collected in that case opennms writes value collected at 10:10 in JRB
file. If opennms miss 2 poll cycles it writes NaN in JRB files.
But our requirement is to collect file(from device) at every 5 minutes and
store value?
How to overcome this problem?
If it miss 2 or more than poll cycles Is it possible for opennms to write
next collected value for those intervals. what is the RRD configuration for
that?
we r using the following RRD configuration
<rrd step="300">
<rra>RRA:AVERAGE:0.5:1:2016</rra>
<rra>RRA:AVERAGE:0.5:12:1488</rra>
<rra>RRA:AVERAGE:0.5:288:366</rra>
<rra>RRA:MAX:0.5:288:366</rra>
<rra>RRA:MIN:0.5:288:366</rra>
</rrd>
Thanks
