第3章 自動生成模版文件

1.自動生成腳本

[root@m01 /etc/ansible/zabbix/auto_template]# cat auto_template.sh
#!/bin/bash

#1.定義變量
TIME=$(date +%FT%H:%M:%SZ)
DIR=/etc/ansible/roles/zabbix/import_template/files

#2.清空文件內容

${DIR}/zabbix_template.xml

#3.生成第一段固定內容
cat >${DIR}/zabbix_template.xml<<EOF

<?xml version="1.0" encoding="UTF-8"?>

<zabbix_export>
4.0
${TIME}


db

新的應用集

#4.循環生成監控項內容
for i in $(cat item_list.txt) do cat >>${DIR}/zabbix_template.xml<<EOF

$(echo ${i}|awk -F"," '{print KaTeX parse error: Expected 'EOF', got '}' at position 2: 1}̲')</name> …(echo ${i}|awk -F"," '{print KaTeX parse error: Expected 'EOF', got '}' at position 2: 2}̲')</key> …(echo ${i}|awk -F"," ‘{print $3}’)

3.觸發器清單

[root@m01 ~]# cat /etc/ansible/zabbix/auto_template/trigger_list.txt
{TCP:TCP_STATUS[LISTEN].last()}=100,LISTEN連接數過多,2
{TCP:TCP_STATUS[ESTABLISHED].last()}=100,ESTABLISHED連接數過多,3
