If this is a problem which just started recently, and your scripts were working fine before January 10, then I suspect you need the fix to IY52758, a very recent APAR which is being tested as I write. It seems that these negative values are the result of a buffer overflow which occurred when the time values grew so large that they could no longer be considered as simple signed integers. The individual values are fine. The problem occurs when the are added together and then divided by 2 to find an average over the interval.
Hi all, I'm having a really annoying problem with xnmgraph. I'm trying to watch the CPU & Bandwidth of a router, so i created the following scripts: #!/usr/bin/ksh # /usr/OV/bin/xnmgraph -title "Router CPU" \ -geometry 600x400 -hidename True -poll 5s \ -mib ".1.3.6.1.4.1.9.9.109.1.1.1.1.3:CPU5sec:1::::::xxx.xxx.xxx.xxx" #!/usr/bin/ksh # /usr/OV/bin/xnmgraph -title "Router Bandwidth" \ -geometry 600x400 -hidename True -poll 5s \ -mib ".1.3.6.1.2.1.2.2.1.10:ifInOctets_s1:7::::::xxx.xxx.xxx.xxx, \ .1.3.6.1.2.1.2.2.1.16:ifOutOctets_s1:7::::::xxx.xxx.xxx.xxx, \ .1.3.6.1.2.1.2.2.1.10:ifInOctets_s0:2::::::xxx.xxx.xxx.xxx, \ .1.3.6.1.2.1.2.2.1.16:ifOutOctets_s0:2::::::xxx.xxx.xxx.xxx" where xxx.xxx.xxx.xxx the loopback address of the router. When i run the scripts everything is fine for the first 4-5 minutes, but then i get some irrelevant values (such as 22000000000 or -34000000000) with no reason and the graphs go crazy! And here is the funniest part. When i saved the graphs, i didn't find any "strange" values inside. So i recreated the graph. When i zoomed in the "strange" values were there!! When i tried to see the statistics the values seemed to be ok. Am I missing something here? Is it something known that i overlooked? Any ideas?
