Cacti 自己写模板监控，

jiangyi_hust

自己添加模板，使用 snmpwalk可以得到数据
#snmpwalk -v 1 192.168.119.10 -c public .1.3.6.1.4.1.2021.53
UCD-SNMP-MIB::ucdavis.53.1.1 = INTEGER: 1
UCD-SNMP-MIB::ucdavis.53.2.1 = STRING: "UP_Time"
UCD-SNMP-MIB::ucdavis.53.3.1 = STRING: "/bin/sh /usr/local/UP_Time.sh"
UCD-SNMP-MIB::ucdavis.53.100.1 = INTEGER: 0
UCD-SNMP-MIB::ucdavis.53.101.1 = STRING: "527.835"
UCD-SNMP-MIB::ucdavis.53.102.1 = INTEGER: 0
UCD-SNMP-MIB::ucdavis.53.103.1 = ""

但是无法cacti无法作图。rra里面的.rrd文件无法读出数据。用rrdtool fetch XXX.rrd AVERAGE取出的数据都是nan！
cacti自带的图如Load Average可以正常出图。

# crontab -l
*/5 * * * * /usr/bin/php /var/www/html/cacti/poller.php > /dev/null 2>&1

rra目录的情况
drwxr-xr-x  2 cactiuser root   4096 Jun 24 18:54 rra


请教cacti高手，如何解决该问题？

用了一个脚本，用snmp去抓。

cacti的日志报错，似乎是snmp的数据无效：

什么原因导致的

cacti论坛上有现成的，干嘛非得自己写呢，去找squid stats
