Centreon不出图

Centreon不出图

Centreon 出图主要看centstorage进程。

不出图现象：

有图无数据，无图无数据。

主要排查方法

看是否有Performance Data：

 

看是否有图形

 

排查办法：

查看日志，主要在/usr/local/centreon/log/ 以及/var/log/ 里面

 

/usr/local/centreon/log/centstorage.log

/usr/local/centreon/log/rrdtool.log

/var/log/httpd/error_log

/var/local/nagios/var/nagios.log

一般都在这4个日志文件中。查看不到图形，目录权限的可能性比较大。查看日志报错，一般都是文件少，或者文件权限问题，再分析数据。

 

分布式后，节点无法出图。nagios日志报错

[1452774398] wproc:   stderr line 01: chmod: changing permissions of `/usr/local/nagios/var/service-perfdata': Operation not permitted

[1452772832] wproc:   stderr line 01: execvp(/usr/local/nagios/libexec/process-service-perfdata, ...) failed. errno is 2: No such file or directory

注意这两个文件权限，777未必能解决问题
