【5】nagios从零学习使用 - centreon使用check_centreon_命令

centreon已定义了非常多常用的snmp命令，对一些服务器若是不想安装nsclient++插件的，可以使用snmp协议。

centreon已定义snmp命令：

/usr/local/nagios/libexec
[root@centreon libexec]# ls check_centreon_*
check_centreon_dummy                 check_centreon_snmp_multiple_process  check_centreon_snmp_TcpConn
check_centreon_MS_multiple_services  check_centreon_snmp_packetErrors      check_centreon_snmp_traffic
check_centreon_ping                  check_centreon_snmp_process           check_centreon_snmp_uptime
check_centreon_snmp_cpu              check_centreon_snmp_process_detailed  check_centreon_snmp_value
check_centreon_snmp_loadaverage      check_centreon_snmp_remote_storage    check_centreon_snmp_value_table.pl
check_centreon_snmp_memory           check_centreon_snmp_string

一般的监控基本上可以满足

windows安装snmp并设置：

在安全中添加public只读，以及填写centreon所在的服务器IP地址。

Linux安装snmp并设置：

[root@centreon libexec]# rpm -qa | grep snmp

net-snmp-libs-5.5-49.el6_5.1.x86_64

net-snmp-perl-5.5-49.el6_5.1.x86_64

net-snmp-utils-5.5-49.el6_5.1.x86_64

net-snmp-5.5-49.el6_5.1.x86_64

php-snmp-5.3.3-27.el6_5.x86_64

设置如下：

[root@centreon log]# cat /etc/snmp/snmpd.conf | grep -v '^#'|sed /^$/d

com2sec notConfigUser  127.0.0.1       public

com2sec notConfigUser  192.168.198.250       public

syslocation Unknown (edit /etc/snmp/snmpd.conf)

syscontact Root (configure /etc/snmp/snmp.local.conf)

dontLogTCPWrappersConnects yes

以check_centreon_snmp_remote_storage为例：

[root@centreon libexec]# ./check_centreon_snmp_remote_storage  --help

##############################################
Usage:
./check_centreon_snmp_remote_storage
   -H (--hostname)   Hostname to query (required)
   -C (--community)  SNMP read community (defaults to public)
                     used with SNMP v1 and v2c
   -v (--snmp-version)  1 for SNMP v1 (default)
                        2 for SNMP v2c
                        3 for SNMP v3
   -P (--snmp-port)  SNMP port (default: 161)
   -k (--authkey)    snmp V3 key
   -u (--username)   snmp V3 username
   -p (--password)   snmp V3 password
   --authprotocol    protocol MD5/SHA  (v3)
   --privprotocol    encryption system (DES/AES)(v3)
   --privpassword    passphrase (v3)
   --64-bits         Use 64 bits OID
   --maxrepetitions  To use when you have the error: 'Message size exceeded buffer maxMsgSize'
                     Work only with SNMP v2c and v3 (Example: --maxrepetitions=1)
   --snmp-timeout    SNMP Timeout
   -d (--disk)       Set the disk (number expected) ex: 1, 2,... (default: 2 )
   -n (--name)       Allows to use disk name with option -d instead of disk oid index
                     (ex: -d "C:" -n, -d "E:" -n, -d "Swap Memory" -n, -d "Real Memory" -n
                     (choose an unique expression for each disk)
   -s (--show)       Lists all disks (debug mode)
   -w (--warn)       Minimum fill level at which a warning message will be generated
                     (default 80)
                     By using the optional suffixes MB/GB the argument is interpreted as absolute size
                     and it becomes a threshold for free space. (ex. 100MB; 3GB)
   -c (--crit)       Minimum fill level at which a critical message will be generated
                     (default 95)
                     By using the optional suffixes MB/GB the argument is interpreted as absolute size

                     ex.: -w 1GB -c 256MB generates a warning when free space reaches 1GB
                          and critical when there are less than 256MB left
   -V (--version)    Plugin version
   -L                add Windows drive label to output
   -M                Shows the size in output in MB instead of GB

centreon里面的设置如下：

检测命令定义之后，可以定义服务模板，这个模板可以给主机模板引用。

主机模板中的关系中可以引用服务，这样常用的模板可以把一些常用的监控添加来。
