Hi, I sent the following mail to nfsen-discuss a week ago, but it apparently did not make it through (probably because I wasn't subscribed). I was able to work around most problems by setting the (mostly undocumented) date.timezone=CET in php.ini. But today, with this setting, I saw a similar ugly behaviour:
I see a peak in the nfsen rrd graph at about 21:30 CET (was there at 21:30 CET, I see the flood in the monitoring). I want to see the destination, so I select the timespan between 21:20 and 21:45, select the router, do "Stat TopN", select "DST IP Address order by bytes" and say process and get ... nothing. Because nfsen did nfdump -R /usr/local/nfsen/profiles/live/backbone1/nfcapd.200701262020:nfcapd.200701262045 -n 10 -s dstip/bytes one hour off. So in fact I need to select 22:20 to 22:45 in the graph to get the correct data for the peak I see in my graphs. Original mail: I've just upgraded to the latest snapshots (but I think I have seen the error before) and have a slight problem with the timezone. It is now Jan. 18th 2006, 00:46. The server collecting the netflow records and running nfsen thinks so as well | teleport svr02% date | Thu Jan 18 00:46:40 CET 2007 The nfcapd-files are also obviously named in the CET timezone | -rw-r--r-- 1 www-data www-data 340368 Jan 18 00:45 nfcapd.200701180040 | -rw-r--r-- 1 www-data www-data 276 Jan 18 00:45 nfcapd.current.29895 but nfsen itself seems to be a little bit confused about it. The graphs on the detail page are showing the times in CET. The profile info is in GMT. The t_start and t_end values are CET again. It appears it tries to read the statistics for the timeslots and anything I try to get from the netflow processing in GMT, because when I select the latest available timeslot (0:40 now) and say "List Flows -> process", it tries to open the wrong file | nfdump -r | /usr/local/nfsen/profiles/./live/backbone16//nfcapd.200701172340 -o line | -c 10 | Can't stat | '/usr/local/nfsen/profiles/live/backbone16/nfcapd.200701172340': No such | file or directory and fails. I've made a screenshot of the details page available at http://users.birkenwald.de/~berni/temp/nfsen.png , if I just press "process" now I will get the error message mentioned above.
