# 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, ifnull(sum(COUNT_STAR),0) as cnt FROM performance_schema.events_statements_summary_by_digest WHERE AVG_TIMER_WAIT >= 100000000000000 UNION
SELECT 'query_rt10s', ifnull(sum(COUNT_STAR),0) as cnt FROM performance_schema.events_statements_summary_by_digest WHERE AVG_TIMER_WAIT BETWEEN 10000000000000 AND 10000000000000 UNION
SELECT 'query_rt1s', ifnull(sum(COUNT_STAR),0) as cnt FROM performance_schema.events_statements_summary_by_digest WHERE AVG_TIMER_WAIT BETWEEN 1000000000000 AND 10000000000000 UNION
SELECT 'query_rt100ms', ifnull(sum(COUNT_STAR),0) as cnt FROM performance_schema.events_statements_summary_by_digest WHERE AVG_TIMER_WAIT BETWEEN 100000000000 AND 1000000000000 UNION
SELECT 'query_rt10ms', ifnull(sum(COUNT_STAR),0) as cnt FROM performance_schema.events_statements_summary_by_digest WHERE AVG_TIMER_WAIT BETWEEN 10000000000 AND 100000000000 UNION
SELECT 'query_rt1ms', ifnull(sum(COUNT_STAR),0) as cnt FROM performance_schema.events_statements_summary_by_digest WHERE AVG_TIMER_WAIT BETWEEN 1000000000 AND 10000000000 UNION
SELECT 'query_rt100us', ifnull(sum(COUNT_STAR),0) as cnt 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 mysql is down on {HOST.NAME}
- 删除原有的使用proc num监控的MySQL is down trigger(多实例下结果不正确)
- 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
### 针对`SHOW SLAVE STATUS`输出，支持多源复制
slave_lag: 取多通道中seconds_behind_master的最大值
running_slave: 当所有通道的slave_io_running和slave_sql_running状态为Yes时, runing_slave值为1
relay_log_space: 取所有通道的relay_log_space的和
## 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_zbx_3.x_template_mysql_server.xml， 添加主机、模板，开始监控
