PNP配置完成后，经常由于各种原因导致无法正确地显示图片，下面推荐一个验证配置的工具


工具：verify_pnp_config.pl

Download

wget http://verify.pnp4nagios.org/verify_pnp_config

Option：

  • --mode One of the modes described on modes

  • --config Location of nagios.cfg or icinga.cfg

  • --pnpcfg Path to PNPs etc directory

Command

perl verify_pnp_config --mode npcdmod --config=/usr/local/nagios/etc/nagios.cfg --pnpcfg=/usr/local/pnp4nagios/etc

bulk模式

 perl verify_pnp_config --mode bulk --config=/usr/local/nagios/etc/nagios.cfg --pnpcfg=/usr/local/pnp4nagios/etc


运行如下：

[root@localhost ~]# perl verify_pnp_config --mode bulk --config=/usr/local/nagios/etc/nagios.cfg --pnpcfg=/usr/local/pnp4nagios/etc
