Django顯示服務器性能監(jiān)控
- 監(jiān)控系統(tǒng)CPU、內(nèi)存和進程信息
- 一、運行環(huán)境與項目目錄
- 二、配置文檔：Setting
- 二、創(chuàng)建 Models，操作數(shù)據(jù)
- 三、創(chuàng)建數(shù)據(jù)庫
- 四、 views.py
- 五、創(chuàng)建html模版
- 六、urls.py添加路由
- 七、運行程序，顯示結(jié)果
監(jiān)控系統(tǒng)CPU、內(nèi)存和進程信息
一、運行環(huán)境與項目目錄
- Django 2.0.7
- python 3.7
- pymysql 0.9.3
二、配置文檔：Setting
1.mysql 數(shù)據(jù)庫
# Author: Allan
# Datetime: 2019-05-21
import pymysql
pymysql.install_as_MySQLdb()
DATABASES = {
'default': {
# 注釋sqlite3
# 'ENGINE': 'django.db.backends.sqlite3',
# 'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
# mysql
'ENGINE': 'django.db.backends.mysql',
'NAME': 'database',
'USER': 'username',
'PASSWORD': 'password',
'HOST': 'ip',
'PORT': 3306,
}
}
2.Application definition
INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'web' #添加App，下面python3 mkmigrations web使用
]
MIDDLEWARE = [
'django.middleware.security.SecurityMiddleware',
'django.contrib.sessions.middleware.SessionMiddleware',
'django.middleware.common.CommonMiddleware',
# 'django.middleware.csrf.CsrfViewMiddleware', 注釋這一行，防止403錯誤
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.contrib.messages.middleware.MessageMiddleware',
'django.middleware.clickjacking.XFrameOptionsMiddleware',
]
ROOT_URLCONF = 'monitor.urls'
TEMPLATES = [
{
'BACKEND': 'django.template.backends.django.DjangoTemplates',
'DIRS': [os.path.join(BASE_DIR, 'templates')], #修改模版目錄
'APP_DIRS': True,
'OPTIONS': {
'context_processors': [
'django.template.context_processors.debug',
'django.template.context_processors.request',
'django.contrib.auth.context_processors.auth',
'django.contrib.messages.context_processors.messages',
],
},
},
]
3.Security
# SECURITY WARNING: don't run with debug turned on in production!
DEBUG = True
ALLOWED_HOSTS = ['*']
4.Internationalization
LANGUAGE_CODE = 'en-us'
# 修改時區(qū)
TIME_ZONE = 'Asia/Shanghai'
USE_I18N = True
USE_L10N = True
# 修改時區(qū)
USE_TZ = False
二、創(chuàng)建 Models，操作數(shù)據(jù)
from django.db import models
# Create your models here.
class CpuInfo(models.Model):
# CPU信息
time = models.DateTimeField()
host = models.CharField(max_length=40)
usage_system = models.FloatField(null=True)
usage_user = models.FloatField(null=True)
usage_softirq = models.FloatField(null=True)
usage_iowait = models.FloatField(null=True)
class MemoryInfo(models.Model):
#內(nèi)存信息
time = models.DateTimeField()
host = models.CharField(max_length=40)
used_percent = models.FloatField(null=True)
class ProcstatInfo(models.Model):
# 進程信息
time = models.DateTimeField()
host = models.CharField(max_length=100)
exe = models.CharField(max_length=40)
pid = models.FloatField()
cpu_usage = models.FloatField(null=True)
memory_rss = models.FloatField(null=True)
三、創(chuàng)建數(shù)據(jù)庫
1.Terminal?下運行manager.py
# python3 manager.py mkmigrations web
# python3 manager.py migrate
2.查詢mysql
mysql> show tables;
ERROR 2006 (HY000): MySQL server has gone away

四、?views.py
創(chuàng)建兩個views，一個顯示CPU和內(nèi)存信息；另一個現(xiàn)實進程信息
# Author: Allan
# Datetime: 2019-05-21
import time
import json
from django.shortcuts import render
from web import models
# Create your views here.
def show_procstat(request):
servers = ['rotestZone01', 'rotestZone02']
procstat_ret = {}
for server in servers:
procstat_info = models.ProcstatInfo.objects.filter(host=server)
procstat_exe = {}
for row in procstat_info:
temp_time = int(time.mktime(row.time.timetuple())) * 1000
key = str(row.exe) + '_' + str(int(row.pid))
if key not in procstat_exe:
procstat_exe[key] = {}
procstat_exe[key]['cpu_usage'] = []
procstat_exe[key]['memory_rss'] = []
procstat_exe[key]['cpu_usage'].append([temp_time, row.cpu_usage])
procstat_exe[key]['memory_rss'].append([temp_time, row.memory_rss])
procstat_ret[server] = procstat_exe
return render(request, 'show_procstat.html', {"procstat_ret": json.dumps(procstat_ret)})
def show_servers(request):
servers = ['rotestZone01', 'rotestZone02']
server_res = {}
cpu_res = {}
mem_res = {}
for server in servers:
cpu_info = models.CpuInfo.objects.filter(host=server)
cpu_ret = {}
usage_system = []
usage_user = []
usage_softirq = []
usage_iowait = []
for row in cpu_info:
temp_time = int(time.mktime(row.time.timetuple())) * 1000
usage_system.append([temp_time, row.usage_system])
usage_user.append([temp_time, row.usage_user])
usage_softirq.append([temp_time, row.usage_softirq])
usage_iowait.append([temp_time, row.usage_iowait])
cpu_ret['usage_system'] = usage_system
cpu_ret['usage_user'] = usage_user
cpu_ret['usage_softirq'] = usage_softirq
cpu_ret['usage_iowait'] = usage_iowait
cpu_res[server] = cpu_ret
mem_info = models.MemoryInfo.objects.filter(host=server)
mem_ret = []
for row in mem_info:
temp_time = int(time.mktime(row.time.timetuple()))*1000
mem_ret.append([temp_time, row.used_percent])
mem_res[server] = mem_ret
server_res['cpu_res'] = cpu_res
server_res['mem_res'] = mem_res
return render(request, 'show_servers.html', {"server_res": json.dumps(server_res)})
五、創(chuàng)建html模版
創(chuàng)建兩個html模版，一個顯示CPU和內(nèi)存信息；另一個現(xiàn)實進程信息

六、urls.py添加路由
# Author: Allan
# Datetime: 2019-05-21
from django.contrib import admin
from django.urls import path
from web import views
urlpatterns = [
# path('admin/', admin.site.urls),
path('show_servers', views.show_servers),
path('show_procstat', views.show_procstat),
]
七、運行程序，顯示結(jié)果
# python3 manager.py runserver
CPU和內(nèi)存信息
進程信息
?
