#actiontech zabbix mysql monitor

percona monitoring plugins zabbix的go语言版本

0. 版本下载使用1.0分支

1. item取值与percona版本差异

使用mysqld端口自动发现相关item（zabbix Low level discovery）

  • innodb_transactions
    取值方法：SHOW /\*!50000 ENGINE*/ INNODB STATUS,可得行Trx id counter 861144，取值861144
    percona将861144作为十六进制字符解析，actiontech版本将861144作为十进制字符解析
  • unpurged_txns：
    取值方法：SHOW /\*!50000 ENGINE*/ INNODB STATUS,可得行Purge done for trx's n:o < 861135 undo n:o < 0，取值861135
    percona将861135作为十六进制字符解析，actiontech版本将861135作为十进制字符解析
  • running_slave，slave_lag:
    取值方法：如果SHOW SLAVE STATUS为空，认为该mysql为master，设置running_slave=1，slave_lag=0；如果SHOW SLAVE STATUS不为空，与percona处理相同，依据slave_io_running及slave_sql_running等具体参数值设置
  • 增加mysqld_port_listen
    取值方法：netstat -ntlp |awk -F '[ :]+|/' '$4~/^port$/{print $8}'其中port为参数传入值
    若上述命令结果等于mysqld，则值为1，反之为0
  • 增加query_rt100s、query_rt10s、query_rt1s、query_rt100ms、query_rt10ms、query_rt1ms(默认关闭，设置get_qrt_mysql参数可开启)
    取值方法select 'query_rt100s' as rt ,count(*) as count from performance_schema.events_statements_summary_by_digest where AVG_TIMER_WAIT >= 100000000000000 union select 'query_rt10s',count(*) from performance_schema.events_statements_summary_by_digest where AVG_TIMER_WAIT between 10000000000000 and 10000000000000 union select 'query_rt1s',count(*) from performance_schema.events_statements_summary_by_digest where AVG_TIMER_WAIT between 1000000000000 and 10000000000000 union select 'query_rt100ms',count(*) from performance_schema.events_statements_summary_by_digest where AVG_TIMER_WAIT between 100000000000 and 1000000000000 union select 'query_rt10ms',count(*) from performance_schema.events_statements_summary_by_digest where AVG_TIMER_WAIT between 10000000000 and 100000000000 union select 'query_rt1ms',count(*) from performance_schema.events_statements_summary_by_digest where AVG_TIMER_WAIT <= 1000000000
  • 增加query_avgrt(默认关闭，设置get_qrt_mysql参数可开启)
    取值方法:select round(avg(AVG_TIMER_WAIT)/1000/1000/1000,2) as avgrt from performance_schema.events_statements_summary_by_digest
  • 去除SHOW /\*!50000 ENGINE*/ INNODB STATUS输出中INDIVIDUAL BUFFER POOL INFO段落的信息，避免重复计算
  • spin_rounds
    取值方法：SHOW /\*!50000 ENGINE*/ INNODB STATUS,可得行 Mutex spin waits 2537, rounds 28527, OS waits 789 RW-shared spins 535, rounds 7850, OS waits 251 RW-excl spins 172, rounds 2334, OS waits 62取值spin_rounds = 28527 + 7850 + 2334
    percona取值spin_rounds = 28527，actiontech版本增加RW-shared spins rounds以及RW-excl spin rounds

2. trigger与percona版本差异

  • 增加MySQL {#MYSQLPORT} max_connections less than 4999 on {HOST.NAME}
  • 增加MySQL {#MYSQLPORT} Open_files_limit less than 65534 on {HOST.NAME}
  • 增加MySQL {#MYSQLPORT} port is not in listen state on {HOST.NAME}
  • 增加{#MYSQLPORT} port is not mysqld on {HOST.NAME}
  • 删除原有的mysql active threads more than 40, mysql connections utilization more than 80%, mysql slave lag more than 300的trigger(zabbix 2.4 LLD下的trigger没有depend功能, 删除这些原本依赖depend的trigger以避免错误)

3. 限制

  • 暂不支持mysql ssl连接方式
  • 不完全支持Percona Server or MariaDB
  • 仅支持zabbix2.4.0及以上版本

4. 增加对mysql 5.7支持

针对SHOW /*!50000 ENGINE*/ INNODB STATUS输出
5.6与5.7的几句差异
mysql 5.6

  • SEMAPHORES输出
    Mutex spin waits 2537, rounds 28527, OS waits 789
    RW-shared spins 535, rounds 7850, OS waits 251
    RW-excl spins 172, rounds 2334, OS waits 62
    计算：
    spin_waits = 2537 + 535 + 172
    spin_rounds = 28527 + 7850 + 2334
    os_waits = 789 + 251 + 62

  • FILE I/O输出
    Pending normal aio reads: 0, aio writes: 0,
    ibuf aio reads: 0, log i/o's: 0, sync i/o's: 0
    计算：
    pending_normal_aio_reads = 0
    pending_normal_aio_writes = 0
    pending_ibuf_aio_reads = 0
    pending_aio_log_ios = 0
    pending_aio_sync_ios = 0

  • LOG输出
    0 pending log writes, 0 pending chkp writes
    计算：
    pending_log_writes = 0
    pending_chkp_writes = 0

  • BUFFER POOL AND MEMORY输出
    Total memory allocated 137363456; in additional pool allocated 0
    计算：
    total_mem_alloc = 137363456
    additional_pool_alloc = 0

mysql 5.7

  • SEMAPHORES输出（移除Mutex spin，新增RW-sx spins）
    RW-shared spins 500, rounds 132474, OS waits 100787
    RW-excl spins 0, rounds 200953, OS waits 6214
    RW-sx spins 28837, rounds 826250, OS waits 26397
    计算：
    spin_waits = 500 + 0 + 28837
    spin_rounds = 132474 + 200953 + 826250
    os_waits = 100787 + 6214 + 26397

  • FILE I/O输出（拆分为每个io thread的值）
    Pending normal aio reads: [1, 2, 3, 4] , aio writes: [5, 6, 7, 8] ,
    ibuf aio reads:, log i/o's:, sync i/o's:
    计算：
    数组全部元素相加， 空值为0
    pending_normal_aio_reads = 1 + 2 + 3 + 4
    pending_normal_aio_writes = 5 + 6 + 7 + 8
    pending_ibuf_aio_reads = 0
    pending_aio_log_ios = 0
    pending_aio_sync_ios = 0

  • LOG输出
    1 pending log flushes, 0 pending chkp writes
    log flushes 与 log writes意义相同，计算方式不变
    计算：
    pending_log_writes = 1
    pending_chkp_writes = 0

  • BUFFER POOL AND MEMORY输出（移除in additional pool allocated）
    Total large memory allocated 137428992
    计算：
    total_mem_alloc = 137428992
    additional_pool_alloc = 0

5. 安装

  1. 安装zabbix-agent
  2. 执行install.sh
    //请检查确保/etc/sudoers中包含#includedir /etc/sudoers.d //install.sh作用仅为拷贝文件至默认路径，可自行调整
  3. 创建采集mysql状态信息的用户
    mysql> grant process,select,replication client on *.* to zbx@’127.0.0.1’ identified by 'zabbix';
  4. 拷贝
    cp /var/lib/zabbix/actiontech/templates/userparameter_actiontech_mysql.conf /etc/zabbix/zabbix_agentd.d/
    //若改变登陆密码或默认路径，请相应调整userparameter_actiontech_mysql.conf
    重启agent
    service zabbix-agent restart
  5. 测试数据采集
    sudo -u zabbix -H /var/lib/zabbix/actiontech/scripts/actiontech_mysql_monitor --host 127.0.0.1 --user zbx --pass zabbix --items max_connections
    //被监控mysql最大连接数
    sudo -u zabbix -H /var/lib/zabbix/actiontech/scripts/actiontech_mysql_monitor --host 127.0.0.1 --user zbx --pass zabbix --items running_slave
    //主从复制状态
    sudo -u zabbix -H /var/lib/zabbix/actiontech/scripts/actiontech_mysql_monitor --discovery_port true
    //json格式的mysqld端口占用
    sudo -u zabbix -H /var/lib/zabbix/actiontech/scripts/actiontech_mysql_monitor --port 3306 --items mysqld_port_listen
    //3306端口是否被mysqld占用
  6. zabbix server导入配置模板actiontech_zabbix_agent_template_percona_mysql_server.xml， 添加主机、模板，开始监控
