Actually, I think this is probably it - thank you. There is an option "unknaszero" (which I assume means to put any unknown response as a zero, and I should have a "unknown as last" instead. I'd rather not artificially put that max at 26, so do you happen to know what the correct option is for unknown as last value? Maybe 'unknaslast'? ----- Original Message ----- From: "Craig Gittens" <cgittens@sunbeach.net> To: <usr-tc@mailman.xmission.com> Sent: Wednesday, August 28, 2002 9:10 AM Subject: RE: [USR-TC] MRTG Help
I would try changing the MAX users setting to 26 or 28. It can be found in the MRTG config file. I have had problems where if the max threshhold is surpassed (could it be counting a telnet as a user?) my MRTG doesn't read it as zero and just repeats the last reading. (Using it for traffic not user count tho) There are other causes. Do you have a firewall between the MRTG box and the 3Com? What type of box are you running MRTG from? I have found that running MRTG from an NT box is flaky sometimes.
This is my first post. yay! We bought a TC unit a while ago..not even sure what model it is..and I haven't set it up yet...hoping to get it done pretty soon...so I will have lots of stupid questions. I did notice that there is a lot of helpful stuff in the headers of the list email so I will try those links first....

Thanks Lewis. I'm not certain it's a timeout at all - I was just guessing that there were actually people online during that time, just that MRTG didn't know it. I'm basically guessing that it didn't get a response quickly enough and records this as zero.
I'm not aware of any network problems, but frankly that's using the 'everything seems fast and seems to work correctly' diagnostic tool. We've been running this modem pool for a couple month's and haven't had any substantial problems reported by users, and I'm pretty sure if we were offline for 45 minutes or so, 4 or 5 times yesterday, we'd have heard about it. :-)
So, that means there really is no Modem Pool problem, just a MRTG problem - or at least some sort of reporting problem. The other reports on that same pool...

don't seem to have any gaps in the data, so it doesn't seem that MRTG has a hard time talking to it in other cases....
So, basically, I'm a newbie on MRTG and I don't really know what to ask, other than 'help.' :-)

Hi. My MRTG graph (http://www.inet2000.com/mrtg/3comtc.modem.html) shows period with no modem use, however we've had no complaints of the system dying for any period of time and the call durations on some of our currently online users are as high as 47 hours for this call (Yes, that's a camper and another issue....) One of the options mrtg has is to reflect a null response as zero rather than the same as the last non-null response mrtg received. Maybe this is something to look into. More to the point would be to fix any network issues that are causing this timeout. -- Lewis Bergman Texas Communications 4309 Maple St. Abilene, TX 79602-8044 915-695-6962 ext 115
