It's pretty easy if you are using RRDtool. It's not yet in JRobin.
RRDtool 1.2 introduced the VDEF tag. JRobin, based on 1.0, has an
SDEF class which is similar, but we have not written the proper
translation to get this to work.
However, if you want, say, a bits in/out graph with 95th percentile
and you are using RRDtool, try this:
report.mib2.HCbits.name=Bits In/Out
report.mib2.HCbits.columns=ifHCInOctets,ifHCOutOctets
report.mib2.HCbits.type=interfaceSnmp
report.mib2.HCbits.command=--title="Bits In/Out" \
DEF:octIn={rrd1}:ifHCInOctets:AVERAGE \
DEF:octOut={rrd2}:ifHCOutOctets:AVERAGE \
CDEF:rawbitsIn=octIn,8,* \
CDEF:rawbitsOut=octOut,8,* \
CDEF:rawtotBits=octIn,octOut,+,8,* \
CDEF:bitsIn=rawbitsIn,UN,0,rawbitsIn,IF \
CDEF:bitsOut=rawbitsOut,UN,0,rawbitsOut,IF \
CDEF:bitsOutNeg=0,bitsOut,- \
CDEF:totBits=rawtotBits,UN,0,rawtotBits,IF \
CDEF:outSum=bitsOut,{diffTime},* \
CDEF:inSum=bitsIn,{diffTime},* \
CDEF:totSum=totBits,{diffTime},* \
VDEF:outpct=bitsOut,95,PERCENT \
VDEF:inpct=bitsIn,95,PERCENT \
GPRINT:totBits:AVERAGE:" Avg \\: %8.2lf %s\\n" \
LINE2:rawbitsIn#00ff00:"Bits In" \
GPRINT:rawbitsIn:AVERAGE:" Avg \\: %8.2lf %s" \
GPRINT:rawbitsIn:MIN:"Min \\: %8.2lf %s" \
GPRINT:rawbitsIn:MAX:"Max \\: %8.2lf %s\\n" \
LINE2:rawbitsOut#0000ff:"Bits Out" \
GPRINT:rawbitsOut:AVERAGE:"Avg \\: %8.2lf %s" \
GPRINT:rawbitsOut:MIN:"Min \\: %8.2lf %s" \
GPRINT:rawbitsOut:MAX:"Max \\: %8.2lf %s\\n" \
LINE2:outpct#000077:"95 pct out" \
GPRINT:outpct:" \\: %8.2lf %s\\n" \
LINE2:inpct#007700:"95 pct in" \
GPRINT:inpct:" \\: %8.2lf %s\\n" \
GPRINT:inSum:AVERAGE:" Tot In \\: %8.2lf %s" \
GPRINT:outSum:AVERAGE:" Tot Out \\: %8.2lf %s" \
GPRINT:totSum:AVERAGE:" Tot \\: %8.2lf %s\\n"
Note that this is for HCbits (the 64 bit SNMPv2 counters). For 32 bit
counters:
report.mib2.bits.name=Bits In/Out
report.mib2.bits.columns=ifInOctets,ifOutOctets
report.mib2.bits.type=interfaceSnmp
report.mib2.bits.command=--title="Bits In/Out" \
DEF:octIn={rrd1}:ifInOctets:AVERAGE \
DEF:octOut={rrd2}:ifOutOctets:AVERAGE \
CDEF:rawbitsIn=octIn,8,* \
CDEF:rawbitsOut=octOut,8,* \
CDEF:rawtotBits=octIn,octOut,+,8,* \
CDEF:bitsIn=rawbitsIn,UN,0,rawbitsIn,IF \
CDEF:bitsOut=rawbitsOut,UN,0,rawbitsOut,IF \
CDEF:bitsOutNeg=0,bitsOut,- \
CDEF:totBits=rawtotBits,UN,0,rawtotBits,IF \
CDEF:outSum=bitsOut,{diffTime},* \
CDEF:inSum=bitsIn,{diffTime},* \
CDEF:totSum=totBits,{diffTime},* \
VDEF:outpct=bitsOut,95,PERCENT \
VDEF:inpct=bitsIn,95,PERCENT \
GPRINT:totBits:AVERAGE:" Avg \\: %8.2lf %s\\n" \

LINE2:rawbitsOut#0000ff:"Bits Out" \
GPRINT:rawbitsOut:AVERAGE:"Avg \\: %8.2lf %s" \
GPRINT:rawbitsOut:MIN:"Min \\: %8.2lf %s" \
GPRINT:rawbitsOut:MAX:"Max \\: %8.2lf %s\\n" \
LINE2:outpct#000077:"95 pct out" \
GPRINT:outpct:" \\: %8.2lf %s\\n" \
LINE2:inpct#007700:"95 pct in" \
GPRINT:inpct:" \\: %8.2lf %s\\n" \
GPRINT:inSum:AVERAGE:" Tot In \\: %8.2lf %s" \
GPRINT:outSum:AVERAGE:" Tot Out \\: %8.2lf %s" \
GPRINT:totSum:AVERAGE:" Tot \\: %8.2lf %s\\n"
Final note: this is for OpenNMS 1.3.x. It is possible to do this on
1.2.x if you have compiled it against RRDtool 1.2. Replace the
"interface" type with "interfaceSnmp".
