## vproc
脚本说明见文档中vproc章节。
进入vproc目录，有单独的说明文档
在设备上运行时将vproc.py改名vproc， 应用程序中会执行vproc脚本
vproc_testcase.py是简单的单元测试
## zabbix_addhost.py
批量添加zabbix主机的脚本。如果有没暴露的参数，请自己修改脚本。页面上能操作的，api都能操作。 zabbix api参考：https://www.zabbix.com/documentation/3.4/manual/api 。有这个脚本为基础，参考文档增加其他功能并不难。
脚本有help命令:
```
useage: zabbix_addhost.py [options]
[+]--baseurl=[any] | zabbix web url | default: http://192.168.9.133:9210
[+]--ipstart=[any] | ip range start | default: 192.168.66.2
[+]--ipend=[any] | ip range end | default: 192.168.66.41
[+]--user=[any] | zabbix web login user | default: Admin
[+]--passwd=[any] | zabbix web login password | default: zabbix
[+]--hostgroup=[any] | host group name | default: tx1
[+]--proxyname=[any] | porxy name | default: ""
[+]--template1=[any] | template name 1 | default: "starnet_tx1_slave_tp"
[+]--template2=[any] | template name 2 | default: "Template OS Linux"
```
- ipstart和ipend，会用ip最后一位数字生成集合。 比如ipstart=192.168.66.2，ipend=192.168.66.41，会添加66.2 66.3 66.4...66.41共40个主机
- proxyname，template1、2默认是有值的，如果想为空，需指定，比如 --proxyname="" --template2=""

# vproc
## 概述
类似linux proc系统，以文件为媒介。应用程序可以定义多个状态值（key/value），在程序运行过程中持续更新到文件中。外部可随时读取文件查询状态值。程序开发者或运维者可以更好的掌控程序的运行状态。
所有key值均采用 app.[group1.gourp2...groupn].item方式组织。末端item为文件，记录监测项的值，前面是多级目录。比如key值vaserver.va0.cameraname，记录状态值的文件为VPORC_ROOT/vaserver/va0/cameraname。 一个监测项对应一个文件
vproc是实现上述功能的命令行工具，python编写
## vproc提供的功能
1. 应用程序调用vproc脚本写状态值。
2. 查询指定key的value值，输出到屏幕。利用此功能，实现了zabbix查询监测项的值。汇总起来统一在zabbix web上展示
3. 提供类似top命令的状态查看功能，不联动zabbix，也能实时掌控自己应用程序的运行状态。
## 使用方法
vproc工具有4个命令。
- 写：
```
# 此命令将创建文件 ROOT_VPROC/app/group1/group2/item，文件内容为value1
./vproc write --key=app.group1.gourp2.item --value=value1
```
- 读：
```
# 将ROOT_VPROC/app/group1/group2/item文件内容打印出来
./vproc read --key=app.group1.gourp2.item
```
- 重置：
```
# 删除ROOT_VPROC/app/group1/目录。相当于重置状态值
./vproc clean --path=app.group1
```
- 查看：
```
# 类似top，每隔1秒刷新输出一次状态值。参数path可以是任意级别，输出的监测项是path下的所有监测项。
./vproc watch --path=app.group1
```
## 注意事项
- 应用程序中单个监测项更新状态频率不宜过快。建议间隔时间1分钟以上
**注意**： 建议在程序（以及能代表一组的流程）启动时、关闭时重置状态，**避免旧的状态值干扰**。
## vproc 典型使用流程，拿vaserver举例:
定义监测项：
- vaserver.license
- vaserver.event_count（发出了多少事件）
- vaserver.va0.taskname（分析通道0的任务名称）
- vaserver.va0.playok （分析通道0视频是否点播成功）
### 应用程序写值
vaserver启动和退出时应调用
```
# 清理旧状态
./vproc clean --path=vaserver
```
vaserver启动、关闭一个va时（假设是编号0）应调用
```
# 清理旧状态
./vproc clean --path=vaserver.va0
```
license校验状态时
```
# 成功写1 失败写0
./vproc write --key=vaserver.license --value=1
```
执行一个任务，打开了一个通道
```
# 然后将任务信息状态更新
./vproc write --key=vaserver.va0.taskname --value=taskname1
```
视频第一帧图像回调到va0
```
./vproc write --key=vaserver.va0.playok --value=1
```
xx秒没有图像回调到va0
```
./vproc write --key=vaserver.va0.playok --value=0
```
### 调试阶段在命令行查看状态
开启一个命令行，运行
```
./vproc watch --key=vaserver
```
类似top命令，每隔1秒更新一次各状态值
### 衔接zabbix
zabbix_agentd会调用
```
./vproc read --key=vaserver.license
# 其他值
...
```
所有状态值汇总到zabbix server中，在web上统一显示所有被检测主机的状态值。vproc是集群监测的一个基石
