I increased the AbsMax value in mrtg yesterday but today it was still generating the same graphs. (traffic doesn't decrease at the same time or interval either) I thought maybe the .log file would have literally "NaN" in it but it didn't. For example, the value of avg incoming traffic was 1254295 during the interval of loss....the normal is almost 7 times as many bytes. Still searching....

However, here is something that you can check. MRTG probably has MaxBytes set for your targets. It will put a NaN value if it is exceeded. This may show up as drops in your graph. Check the log files to verify. If so, you can set a AbsMax or set the MaxBytes higher. Or set an if-speed in cricket equal to the MaxBytes in MRTG. This may resolve the discrepancies. Check cricket documentation for details on setting up something like MaxBytes in MRTG. --------------sample in Defaults file for cricket-------------------- graph --default-- y-max = %if-speed% rrd-graph-args = "HRULE:%if-speed%#FF0000:Bandwidth(100%)" --------------sample in config file for cricket-------------------- target-type = sub-interface if-speed = 1572864 fmt-speed = "1.544 Mbits/sec" -----Original Message----- From: Tavaris Thomas [mailto:[EMAIL PROTECTED] Sent: Wednesday, December 18, 2002 8:27 AM To: RRD List (E-mail) Subject: [rrd-users] mrtg please help I sent this out 2 days ago and no one responded. If I am being too vague in my email then please let me know and I will provide as much info as I can. Hi everyone, I am using cricket and mrtg (running on separate boxes but on the same segment) to poll various routers. Cricket is using rrdtool but mrtg is not. My question is that recently one of the routers I poll is showing drops in bandwidth on mrtg but not on cricket. When I log onto the router itself and check, it shows no drops in traffic either. There is something wrong with MRTG but I can't for the life of figure out what it could be. I have checked log files and error messages but they are not coming up with anything. I also checked the routers_name.log file in the httpd/mrtg dir and it clearly shows a drop in avg incoming traffic for a couple of 5 minute intervals (so I assume that mrtg is working correctly) but I am stumped. Have I overlooked anything?? Can anyone provide me with any insight? -Thanks and Regards Tavaris Thomas - Internetworking Support Group (FIRN) Department of Education/ Florida Information Resource Network 325 W.
