Hi there, I am trying to understand a specific configuration of MRTG used to monitor jitter and packet loss of various endpoints (videoconference codecs) on the network. In fact, I would like to retrieve the output data, used by MRTG to create the png files, to calculate the Mean Opinion Score of videoconference sessions. The actual configuration produces two log files for the jitter and packet loss values (and also png, png.meta, html.meta, html files...Etc) which are organized as explained in the 'mrtg-logfile' documentation (5 columns, the first one is the timestamp I guess).
Now, I would like to use these files to produce another file containing the MOS for a specific endpoint but I do not understand the section that explains how to convert the timestamp on open office or MS Excel (is Y the 300 seconds interval between each values ?), and do not see how to get a jitter value or packet loss value for each time T interval. The config file of mrtg is as shown below (do not know if it helps): WriteExpires: Yes WorkDir: /mrtg/data/poly/xxx #IconDir: //nms.ucsc.edu/images/ Target[poly-201-loss]: `/mrtg/config/xxx/get_poly-loss` Maxbytes[poly-201-loss]: 10000 XSize[poly-201-loss]: 600 YSize[poly-201-loss]: 300 Ylegend[poly-201-loss]: Drops per hour LegendI[poly-201-loss]: Transmit Loss LegendO[poly-201-loss]: Receive Loss Legend1[poly-201-loss]: Audio + Video transmit drops/hour Legend2[poly-201-loss]: Audio + Video receive drops/hour Title[poly-201-loss]: Packet loss ShortLegend[poly-201-loss]: Packeteer PageTop[poly-201-loss]: <H1>Loss reports from RTCP</H1> <TABLE> <TR><TD>System:</TD><TD>Polycom VSX 8000</TD></TR> / Can be changed to codec's name / <TR><TD>Location:</TD><TD>UK</TD></TR> <TR><TD>Software:</TD><TD>HF 9.0.1</TD></TR> <TR><TD>Command:</TD><TD>advnetstats</TD></TR> </TABLE> Options[poly-201-loss]: growright, nopercent, perhour Target[poly-201-jit]: `/mrtg/config/xxx/get_poly-jitter` Maxbytes[poly-201-jit]: 400 XSize[poly-201-jit]: 600 YSize[poly-201-jit]: 150 Ylegend[poly-201-jit]: mS LegendI[poly-201-jit]: Transmit jitter LegendO[poly-201-jit]: Receive jitter Legend1[poly-201-jit]: Video transmit jitter Legend2[poly-201-jit]: Video receive jitter Title[poly-201-jit]: jitter ShortLegend[poly-201-jit]: Jitter PageTop[poly-201-jit]: <H1>Jitter reports from RTCP</H1> <TABLE> <TR><TD>System:</TD><TD>Polycom VSX 8000</TD></TR> <TR><TD>Location:</TD><TD>UK</TD></TR> <TR><TD>Software:</TD><TD>HF 9.0.1</TD></TR> <TR><TD>Command:</TD><TD>advnetstats</TD></TR> </TABLE> Options[poly-201-jit]: growright, gauge, nopercent By advance thank you for your help.
