losing data<br><br>Hello,<br><br>I recently setup mrtg to monitor firewall traffic, but am experiencing some difficulties.<br><br>My problem:<br>-----------------<br>My graphs seem to randomly lose all historical data at least once a day
(no errors in the mrtg.log file). The corresponding mrtg-logfile shows
all zeros except for the first few entries when this happens. Also, I noticed that my logfile goes missing on regular occasions and only the .old file remains.<br><br>My setup:<br>---------------<br>-Using mrtg version
2.15.1 on Fedora Core 7<br>-cronjob running every 5 minutes to pull data<br>-used cfgmaker to produce my config file and made a few small changes (added WithPeak[_]: ymw, XSize[_]: 600, and YSize[_]: 200)<br><br>I'm a new mrtg user, but I've scoured the FAQ and haven't found any resolutions to my problem.
<br><br>Any ideas on why I'm loosing data in the mrtg-logfile?<br><br clear="all">Thanks!<br><br>
