1.mysql

1.1準備環境打包

go env   #檢視go的變數環境
mkdir -p $GOPATH/src/github.com/open-falcon
cd $GOPATH/src/github.com/open-falcon
git clone https://github.com/open-falcon/mymon.git
 
cd mymon
go get ./...
go build -o mymon

2.新增定時任務

#mysql monitoring
* * * * * cd /home/src/github.com/open-falcon/mymon && ./mymon -c etc/mon.cfg
 

3.環境配置詳解

[default]
    log_file=mymon.log # 日誌路徑和檔名
    # Panic 0
    # Fatal 1
    # Error 2
    # Warn 3
    # Info 4
    # Debug 5
    log_level=4 # 日誌級別
 
    falcon_client=http://127.0.0.1:1988/v1/push # falcon agent連線地址
 
    #自定義endpoint
    endpoint=127.0.0.1 #若不設定則使用OS的hostname
 
    [mysql]
    user=root # 資料庫使用者名稱
    password= # 資料庫密碼
    host=127.0.0.1 # 資料庫連線地址
    port=3306 # 資料庫埠
 

僅供參考,具體配置,根據自己環境修改

2.redis監控

2.1下載原始碼新增hosts

git clone https://github.com/ZhuoRoger/redismon.git
vim /etc/hosts
127.0.0.1 redis

2.2 修改配置檔案

[[email protected] /home/src/github.com/redismon/conf]# vim redismon.conf 
items:
- {cluster_name: redis, password: '', port: 6379}
#- {cluster_name: Redis_Cluster_Slave_82, password: '', port: 7379
修改redis_monitor.py
[
 
[email protected] /home/src/github.com/redismon/bin]# vim redis_monitor.py
redis_falcon_monitor = RedisFalconMonitor(redis_clusterName, redis_port,redis_password,redis_clusterName)  
redis_clusterName既是endpoint 
加入定時任務
#redis montions
*/1 * * * * python /home/src/github.com/redismon/bin/redis_monitor.py

2.3 可能的報錯及解決方法

import yaml ImportError: No module named yaml

解決:yum  install python-yaml

  File "/home/src/github.com/redismon/bin/redis_monitor.py", line 8, in <module>

  import requests

  ImportError: No module named requests    #缺少requests,直接安裝即可

解決: yum install python-requests -y

File "redis_monitor.py", line 9, in <module>
 import redis
ImportError: No module named redis

解決: yum install -y  python-redis

3.mongodb監控

3.1 準備環境下載原始碼

mkdir -p $GOPATH/src/github.com/open-falcon
cd $GOPATH/src/github.com/open-falcon

git clone https://github.com/ZhuoRoger/mongomon.git

3.2 修改配置

cd mongomon/conf

[[email protected] /home/src/github.com/open-falcon/mongomon/conf]# cat mongomon.conf 
items:

-  {port: 234567 , user: "flah",password: user: "123456"}

3.3 啟動

cd $GOPATH/src/github.com/open-falcon/mongomon/bin/  &&  python  mongodb_monitor.py

報錯：

[[email protected] /home/work/mongomon/bin]# python mongodb_monitor.py 
Traceback (most recent call last):
  File "mongodb_monitor.py", line 9, in <module>
    import yaml

ImportError: No module named yaml

解決：

4. LVS監控

4.1環境準備

rpm -qa |grep libnl3.x86_64

yum install -y libnl3.x86_64  #環境需要

mkdir -p $GOPATH/src/github.com/open-falcon/
cd $GOPATH/src/github.com/open-falcon/

git clone https://github.com/mesos-utility/lvs-metrics.git

cd $GOPATH/src/github.com/open-falcon/lvs-metrics
make bin
