Zabbix 6 监控 kingbase V8数据库(二)

zabbix 监控kingbase 单机库

Zabbix 6 监控 kingbase V8数据库(一) 完成元数据库的安装、数据导入以及zabbix server的配置。接下来我们使用zabbix 配置zabbix 监控项目。

配置zabbix agent

# egrep -v '$^|#' /etc/zabbix/zabbix_agentd.conf
PidFile=/run/zabbix/zabbix_agentd.pid
LogFile=/var/log/zabbix/zabbix_agentd.log
LogFileSize=0
Server=192.168.2.171 ##zabbix server ip
ServerActive=192.168.2.171 ##zabbix server ip
Hostname=kdb-192.168.2.152 ##zabbix host
Include=/etc/zabbix/zabbix_agentd.d/*.conf

启动zabbix agent

# systemctl start zabbix-agent.service

创建监控Host

创建Host groups

创建host，添加监控模板

添加监控模板Linux by Zabbix agent

监控模板下载地址：
https://git.zabbix.com/projects/ZBX/repos/zabbix/browse/templates/db/postgresql

Template DB KingbaseES 是导入下载的template_db_postgresql.xml

克隆监控模板

克隆模板

调试监控项

配置宏定义

监控kingbase

CREATE USER zbx_monitor WITH PASSWORD 'kingbase' INHERIT;
CREATE ROLE
GRANT pg_monitor TO zbx_monitor;
GRANT ROLE
-- To collect WAL metrics, the user must have a `superuser` role.
ALTER USER zbx_monitor WITH SUPERUSER;

修改数据库配置文件

# egrep -v "#|^$" /data/kingbase/data_R6/sys_hba.conf
local   all             all                                                trust
host    all             zbx_monitor     127.0.0.1/32                       trust
host    all             all                     0.0.0.0/0                  scram-sha-256
host    all             all                     ::1/128                    scram-sha-256
host    all             all                     ::0/0                      scram-sha-256
local   replication     all                                                trust
host    replication     all                 127.0.0.1/32                  scram-sha-256
host    replication     all                 ::1/128                       scram-sha-256

修改 /etc/zabbix/zabbix_agentd.d/template_db_postgresql.conf
注意 zabbix agent安装默认创建zabbix 用户，zabbix用户需要有ksql和sys_isready权限。
方法：复制1份数据库安装软件，授权zabbix用户权限，属主属组

重启zabbix agent

# systemctl restart zabbix-agent.service

查看监控项目数据

监控项的阈值需要根据实际业务调整。
