rrdtool 插入数据都是NAN

liduan

我现在已经正常安装了RRDTOOL  想抓取我们机房的dlink 交换机的端口流量


这是我网上找的脚本

#!/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}


这是的rrd文件

我不管是把脚本设置成5分钟插入一次 还是手动插入 数据都是NAN

这是我执行脚本返回的结果

[root@localhost soft]# ./ifindex.sh
3702695729
3001957961
return_value = 0
[1341662700]RRA[AVERAGE][1]DS[eth0_in] = NaN
[1341662700]RRA[AVERAGE][1]DS[eth0_out] = NaN
[1341663300]RRA[AVERAGE][1]DS[eth0_in] = NaN
[1341663300]RRA[AVERAGE][1]DS[eth0_out] = NaN
[1341663600]RRA[AVERAGE][1]DS[eth0_in] = NaN
[1341663600]RRA[AVERAGE][1]DS[eth0_out] = NaN

交换机端口肯定是有流量的 但是我为什么插入进去的都是NAN呢 求大侠讲下吧 我已经折腾了1天了
