Zenoss学习杂记（五）

使用zenoss用户登陆后，让我们看看目录下面都是些什么：

 

[zenoss@localhost ~]$ ls -l

drwxrwxr-x   2 zenoss zenoss  4096 Mar 27 22:34 var

 

先看看README.txt

 

[zenoss@localhost ~]$ vi README.txt  

This directory contains an "instance home" for the Zope application
server.  It contains the following directories:

  bin/         Scripts used to control the Zope instance <==Zope脚本
  etc/         Configuration files <==配置文件
  Extensions/  Python sources for External Methods <==Python源码 
  log/         Log files <== 日志文件
  lib/python/  Installed Python packages specific to the instance <== Python库
  Products/    Installed Zope Products specific to the instance <== Zope设备
  var/         Run-time data files, including the object database <==缓存文件

 

对我来说比较重要的目录是/etc，/log，/perf和/var

 

先来看看/etc目录下面，这个目录下面我用到最多的是sysconfig子目录：

 

[zenoss@localhost /]$ cd /etc/sysconfig/
[zenoss@localhost sysconfig]$ ls -l
total 96
-rw-r--r--  1 root root   13 Mar 21 13:06 appliance-group

-rw-r--r--  1 root root  454 Jul  8  2004 syslog
-rwxr-xr-x  1 root root  115 Feb 16  2005 system-config-securitylevel

 

这里的network文件就是配置主机名的地方，而network-scripts目录下面则包含了Zope的网络信息，主要是看ifcfg-eth0文件，这是网卡的第一个接口，如果需要配置固定IP，除了Zenoss自带的管理界面，就是到这里来配置了（记得先给zenoss用户权限）

 

[zenoss@localhost network-scripts]$ vi ifcfg-eth0  

# Device file installed by rBuilder
DEVICE=eth0
BOOTPROTO=dhcp
#BOARDCAST=xxx.xxx.xxx.xxx
#IPADDR=xxx.xxx.xxx.xxx
#NETMASK=xxx.xxx.xxx.xxx
#NETWORK=xxx.xxx.xxx.xxx
#HWADDR=XX:XX:XX:XX:XX:XX
#GATEWAY=xxx.xxx.xxx.xxx
NETWORKING=yes
ONBOOT=yes
TYPE=Ethernet

 

可以看到BOOTPROTO中目前配置的是dhcp，如果这里换成static，并将后面的条目激活，即可配置成静态IP地址。最后重启network服务

 

[root@localhost ~]# service network restart
Shutting down interface eth0:  [  OK  ]
Shutting down loopback interface:  [  OK  ]
Bringing up loopback interface:  [  OK  ]
Bringing up interface eth0:  
Determining IP information for eth0... done.
[  OK  ]

 

看完了/etc目录来看/log目录，这里存放着Zenoss-Core所有的日志文件，也是做Troubleshooting最常来的地方：

最常看的日志是zenactions.log，这个日志里记录了Zenoss-Core处理信息

 

[zenoss@localhost log]# vi +100000 zenactions.log

 

2008-03-31 18:41:30 INFO zen.ZenActions: sent email:[zenoss] CLEAR: DeviceName xxx ip xxx.xxx.xxx.xxx is up to:[' [email protected]']
2008-03-31 18:41:30 INFO zen.ZenActions: processed 2 rules in 0.49 secs

2008-03-31 18:44:30 INFO zen.ZenActions: processed 2 rules in 0.01 secs

2008-03-31 18:45:30 INFO zen.ZenActions: processed 2 rules in 0.02 secs

 

其次要看的是zencommand.log，这里记录了Zenoss-core每个命令的反馈信息：

 

[zenoss@localhost log]# vi +100000 zencommand.log

2008-03-30 04:34:42 INFO zen.zencommand: ---------- - schedule has 0 commands
2008-03-30 10:34:42 INFO zen.zencommand: ---------- - schedule has 0 commands
2008-03-30 16:34:42 INFO zen.zencommand: ---------- - schedule has 0 commands
2008-03-30 22:34:43 INFO zen.zencommand: ---------- - schedule has 0 commands
2008-03-31 04:34:43 INFO zen.zencommand: ---------- - schedule has 0 commands
2008-03-31 10:34:43 INFO zen.zencommand: ---------- - schedule has 0 commands
2008-03-31 16:34:43 INFO zen.zencommand: ---------- - schedule has 0 commands

 

然后是zenperfsnmp，记录了snmp的反馈信息，如果SNMP工作不正常或采集不到数据可以到这里来找原因

 

[root@localhost log]# vi +100000 zenperfsnmp.log

2008-03-31 18:25:13 INFO zen.zenperfsnmp: Count 7 good 6 bad 0 time 0.136089
2008-03-31 18:25:13 INFO zen.zenperfsnmp: sent 196 OID requests

2008-03-31 18:30:13 INFO zen.zenperfsnmp: Count 7 good 2 bad 0 time 0.096148
2008-03-31 18:30:13 INFO zen.zenperfsnmp: Count 7 good 3 bad 0 time 0.112122
2008-03-31 18:30:13 INFO zen.zenperfsnmp: Count 7 good 4 bad 0 time 0.136160
2008-03-31 18:30:13 INFO zen.zenperfsnmp: Count 7 good 5 bad 0 time 0.159661
2008-03-31 18:30:13 INFO zen.zenperfsnmp: Count 7 good 6 bad 0 time 0.175987

 

看过了/log目录，再接下来是/perf目录，这里存放的是Zenoss-Core的ZenPack信息以及设备的信息：

 

[zenoss@localhost ~]$ cd perf/Devices

 

所有设备的信息都被保存在这里，如果需要单独Troubleshooting某一个设备，可以直接到这里来找。

 

最后看的是/var目录，这里的缓存文件很重要，很多时候Zenoss不能正常工作就是因为缓存文件没有及时清理，所有的缓存文件都是以.zec结尾的：

 

[root@localhost var]# ls -l

如果遇到不能正常打开Zenoss Web界面，请尝试以下方法：

 

[root@localhost var]# zpoectl stop
[root@localhost var]# rm zeo1-1.zec
[root@localhost var]# zpoectl start

 

下一篇会讲如何解决RRD不能正常更新的问题以及如何使用Nagios Plugin
