Hi, I am having some problems with unexpected NaN values in one of my rrd files. First, a little background. I have been using rrd to monitor four of our firewall complexes for about a month, after moving over from MRTG. It has been working great. Yesterday, I added six more complexes to the data collection and graphing (BTW, I am using one rrd file per firewall). All but one of these is working as expected.
The file I was having some problems with was producing all NaN values, which seemed odd to me since I am logging all the updates to the rrd, and can see the values that are being sent via the update. I compared the create statement that I used to create this database with the others that were working fine, but could find no difference. Thinking that possibly the file somehow became corrupt, I renamed it and created a new one. This time the DS's defined as GAUGE were reporting the expected values, but all other DS's, which are COUNTER, were still NaN. To try to show what is happening, here is an excerpt from my log file logging the updates: blh-ebiz-int-fw-1: 2006-11-02 11:00:01 1162483201: 274020059,449740761,48821, # columns are: time: accepted, dropped, numconnections, and are COUNTER, COUNTER, GAUGE blh-ebiz-int-fw-1: 2006-11-02 11:05:00 1162483500: 274294130,450001999,49216, blh-ebiz-int-fw-1: 2006-11-02 11:10:00 1162483800: 274574808,450261670,48413, The delta between the first two entries is 274071 for accepted, 261238 for dropped. The delta between the next two is 280678 for accepted , 259671 for dropped. If I do a fetch for that time period: # ../bin/rrdtool fetch fwstats_blhint1.rrd -s 1162483000 -e 1162483800 AVERAGE accepted dropped numcon acceptpcktsin acceptpcktsout inspectpckts requestedbytes allocatedbytes usedbytes 1162483200: NaN NaN NaN NaN NaN NaN NaN NaN NaN 1162483500: NaN NaN NaN NaN NaN NaN NaN NaN NaN 1162483800: NaN NaN NaN NaN NaN NaN NaN NaN NaN 1162484100: NaN NaN NaN NaN NaN NaN NaN NaN NaN Here is the command used to create the file: ../bin/rrdtool create fwstats_blhint1.rrd DS:accepted:COUNTER:600:U:U DS:dropped:COUNTER:600:U:U DS:numcon:GAUGE:600:U:U DS:acceptpcktsin:COUNTER:600:U:U DS:acceptpcktsout:COUNTER:600:U:U DS:inspectpckts:COUNTER:600:U:U DS:requestedbytes:GAUGE:600:U:U DS:allocatedbytes:GAUGE:600:U:U DS:usedbytes:GAUGE:600:U:U RRA:AVERAGE:0.5:1:600 RRA:AVERAGE:0.5:6:700 RRA:AVERAGE:0.5:24:775 RRA:AVERAGE:0.5:288:797 It is probably something very simple, but I cannot for the life of me find out what is wrong, or why. I would greatly appreciate it if someone could help me find out where I went wrong, so I can get this corrected.
