前面的文章我们已经讲过zabbix如何使用snmp监控服务器，但是他有一个很明显的局限性：只能监控定义好的OID项目，假如我们想知道nginx进程是否在运行？在没有zabbix agent的情况下，我们该怎么做呢？接下来就用这个实力来讲解自定义OID
首先我们需要找一个oid是否被系统暂用，比如.1.3.6.1.4.1.2021.5000
| # snmpwalk -v 2c -c public www.ttlsa.com .1.3.6.1.4.1.2021.5000 |
| UCD-SNMP-MIB::ucdavis.5000 = No Such Object available on this agent at this OID |
如上说明不存在
编写脚本
| # cat /root/scripts/check_nginx.sh |
| #!/bin/bash |
| nginxNum=`/bin/psaux | /bin/grepnginx |wc-l` |
| echo$nginxNum |
修改配置
| # vim /etc/snmp/snmpd.conf |
| extend .1.3.6.1.4.1.2021.5000 check_nginx /root/scripts/check_nginx.sh // 增加这一行 |
以下获取自定义的oid的所有数据，第一行便是我们需要获取的数据，那么在zabbix中写oid .1.3.6.1.4.1.2021.5000.4.1.2.11.99.104.101.99.107.95.110.103.105.110.120.1
| # snmpwalk -v 1 -c public 173.219.255.122 .1.3.6.1.4.1.2021.5000 |
| UCD-SNMP-MIB::ucdavis.5000.1.0 = INTEGER: 1 |
| UCD-SNMP-MIB::ucdavis.5000.2.1.2.11.99.104.101.99.107.95.110.103.105.110.120 = STRING:"/root/scripts/check_nginx.sh" |
| UCD-SNMP-MIB::ucdavis.5000.2.1.3.11.99.104.101.99.107.95.110.103.105.110.120 ="" |

snmp-oid
snmp获取nginx数据
接下来创建触发器以及报警，我就不多说了，大家可以参考《zabbix触发器》
zabbix snmp自定义OID nginx监控实例（55）
