cacti监控tomcat8遇到问题

cheng029

cacti---> console --> Data Input Methods ---> Tomcat Status-->Input String
执行命令填写的是：
/usr/bin/perl <path_cacti>/scripts/tomcatstats.pl <hostname>:8086 test test "http-nio-8086"

手动执行命令：
[iyunv@osa scripts]# /usr/bin/perl /home/wwwroot/default/cacti/scripts/tomcatstats.pl 192.168.0.86:8086 test test \"http-nio-8086\"
jvm_memory_free:1355911000 jvm_memory_max:22543335424 jvm_memory_total:2905604096 connector_max_time:47117 connector_error_count:35 connector_bytes_sent:28009534 connector_processing_time:360250 connector_request_count:69399 connector_bytes_received:14892 connector_current_thread_count:25 connector_min_spare_threads: connector_max_threads:2000 connector_max_spare_threads: connector_current_threads_busy:1                                       
完全没有问题。
但cacti确报错抓不到数据，日志如下：
[iyunv@osa scripts]# tailf ../log/cacti.log

^C
纠结好几天了，有没有人知道怎么回事的？附件是使用的脚本和模板，处理改成监控8086端口其他没改。
使用的是http://forums.cacti.net/download.php?id=12310 这个模板
百度云附件：tomcatstats.pl等
