rrdtool 插入數據都是NAN

rrdtool 插入數據都是NAN

我現在已經正常安裝了RRDTOOL  想抓取我們機房的dlink 交換機的埠流量


這是我網上找的腳本

#!/bin/bash

index=$(snmpwalk -v 2c -c public 192.168.1.1  RFC1213-MIB::ifDescr |grep -w IF-MIB::ifDescr.1 |cut -d '=' -f 1|cut -d '.' -f 2)

eth0_in=$(snmpget -v 2c -c public  -IR -Os 192.168.1.1 ifInOctets.${index}|cut -d ':' -f 2|tr -d '[:blank:]')
eth0_out=$(snmpget -v 2c -c public  -IR -Os 192.168.1.1 ifOutOctets.${index}|cut -d ':' -f 2 |tr -d '[:blank:]')
echo $eth0_in
echo $eth0_out
now=$(date +%s)
rrdtool updatev /var/soft/eth0.rrd ${now}:${eth0_in}:${eth0_out}


這是的rrd文件


# rrdtool info eth0.rrd
filename = "eth0.rrd"
rrd_version = "0003"
step = 300
last_update = 1341662539

rra.cdp_prep.unknown_datapoints = 144
rra.cdp_prep.value = 0.0000000000e+00
rra.cdp_prep.unknown_datapoints = 144


我不管是把腳本設置成5分鐘插入一次 還是手動插入 數據都是NAN

這是我執行腳本返回的結果

# ./ifindex.sh
3702695729
3001957961
return_value = 0
RRADS = NaN
RRADS = NaN
RRADS = NaN
RRADS = NaN
RRADS = NaN
RRADS = NaN

交換機埠肯定是有流量的 但是我為什麼插入進去的都是NAN呢 求大俠講下吧 我已經折騰了1天了
