1) Why are we specifying max bytes when we are using MRTG to monitor rtt, packetloss,cpuload etc?
Historical reasons. Originally, MRTG was designed to monitor just network traffic. 2)options [:]:integer.......what does this option....The mrtg website says "Print summary lines below graph as integers without commas" Below graphs, you get text summaries like 'Max In: ... Avg In: ... Last In: ...' giving the Max, Avg and Last values for the data. If the 'integer' option is given, these values are printed as integers. This is useful if you are graphing (for example) number of active data lines. Then 0.5 line doesnt make sense. 3) I can monitor rtt and packet loss with MRTG by making use of mrtg-ping-probe.... what does these two values represent...... These are the two values given to MRTG to store for graphing. In the case of mrtg-ping-probe, they are the highest and lowest RTT from the set of ping probes. So, if you send 5 probes, you'll get a range. The routers2 frontend spots this and graphs it as a floating bar to display the range of ping response times. Steve
