I added CRC with the DS value DERIVE since I wanted to see the number of increase in every 5 mins....i.e. I should get spikes when the CRC increases.... My graph shows the spikes but the y axis values are not correct.... they are in the form of 1m, 2m , 3m .... i.e. in mili and another one if of the form of k.... I thought I should have got exact numbers....Why am I getting incorrect values.... One more thing.... does the snmp values differ with the model number....My router of series 2600 is giving me correct values ( exactly as what is there when I log into the router and find out) but 36xx and 72xx is giving me incorrect values.....Is my observation incorrect or is it that there is some difference when the model number changes.... I really need help on this.... Thanks Janet Post <[EMAIL PROTECTED]> wrote: I monitor everything but the Reliablility of the router, (what is the OID? I think I would like to watch this!) I use the Gauge option like Alex van den Bogaerdt suggested. I have my MAX set to some ridiculously low number: like 50 or 100. But then I set the ABSMAX to some ridiculously high number like 500,000. This means that you will see activity on the graph right away, and the graph will scale nicely if the errors start piling up. The graph will continue to rise until you reset your routers.
I've thought about using THRESHOLD to alert me when one of these counters goes above 5 or 10, but I haven't played with it yet. If anyone out there has done this, please let me know.

I have got the OIDs and its getting the data but the problem is that I am not getting wether to give them as GAUGE, COUNTER or DERIVE and what to give as MIN and MAX ....... GAUGE: read the number from the device and use this as the rate. COUNTER: read the number, subtract the previous number, divide by time, use this as the rate. The difference between COUNTER and DERIVE is that DERIVE can show a negative rate whereas COUNTER will only show positive rates. Example: a 5-digit counter will go from 99999 to 99998. DERIVE will see a counter that counted back by 1, COUNTER will see a counter that increased 99999 (and wrapped). In both cases the resulting change is then divided by the time lapsed. (Note: COUNTER will work with 32 bit and 64 bit counters only. The example won't work, this was just to explain the mechanism). Reliability will be a number, meaning something like "in the past five minutes, the reliability was 255 out of 255". Use GAUGE for this. This will make MRTG show "255" (when all is right). The number of Resets will be low. One reset every five minutes is highly unlikely. OTOH using a GAUGE here isn't good as well. _If_ visible at all, you will have to spot the line going up by one. Probably the best you can do is to use COUNTER together with the PerHour option. The number of CRC errors _should_ be low. Low enough so that the same behaviour is seen as with Resets. This means you should use the same approach. If the number is higher, you may want to change PerHour into PerMinute, or maybe drop the option altogether.
