二、postgres的监控设置
1、目的
postgres的版本号;
是否存活;
连接数;
每秒处理数 (tps) .
2、简略实施步骤
zabbix的自定义脚本采集数据;
自定义模板文件
自定义screen显示
3、zabbix_agentd.conf 配置增加
#20130104 for postgres
#Get the PostgreSQL version
UserParameter=psql.version,psql -U postgres --version|head -n1
#Get the total number of Server Processes that are active
UserParameter=psql.server_processes,psql -U postgres -t -c "select sum(numbackends) from pg_stat_database"
#Get the total number of commited transactions
UserParameter=psql.tx_commited,psql -U postgres -t -c "select sum(xact_commit) from pg_stat_database"
#Get the total number of rolled back transactions
#UserParameter=psql.tx_rolledback,psql -U postgres -t -c "select sum(xact_rollback) from pg_stat_database"
#Get postgres alive status,1=alived,others dead
UserParameter=psql.alive,psql -U postgres -p 5432 -Atqc "select '1'"
4、zabbix_server 设置
增加postgres组;
增加db01和db02为组成员,并增加postgres模板文件;
增加北京机房postgres状态的screen。
5、postgres模板文件内容
