1、畫圖代碼
一、收集處理數據html
class GraphGenerator(object):
'''
generate graphs
'''
def __init__(self,request,redis_obj):
self.request = request
self.host_id = self.request.GET.get('host_id')

print("sub service key:", self.sub_service_name)
def get_graph_data(self):
#data_store_key = "StatusData_%s_%s_latest" %(self.host_id,self.service_name)
data_store_key = "StatusData_%s_%s_%s" %(self.host_id,self.service_name,self.time_range)
data_set = self.redis.lrange(data_store_key,0,-1)
print("data store key:", data_store_key)
print("data point nums:", len(data_set))
#print("data points:", data_set)

val,timestamp = json.loads(data_point)
if val:
for k,v in val.items():

二、生成流量圖python
from monitor import models
import json
from CrazyMonitor import settings
class GraphGenerator2(object):
'''
產生流量圖
'''
def __init__(self,request,redis_obj):
self.request = request
self.redis = redis_obj
self.host_id = self.request.GET.get('host_id')
self.time_range = self.request.GET.get('time_range')
def get_host_graph(self):
'''
生成此主機關聯的全部圖
:return:
'''
host_obj = models.Host.objects.get(id=self.host_id)
service_data_dic = {}
template_list = list(host_obj.templates.select_related())
for g in host_obj.host_groups.select_related():
template_list.extend(list(g.templates.select_related()))
template_list = set(template_list)
for template in template_list:
for service in template.services.select_related():
service_data_dic[service.id] = {
'name':service.name,
'index_data':{},

'raw_data':[],
'items': [item.key for item in service.items.select_related() ]
}
'''if not service.has_sub_service:
for index in service.items.select_related():
service_data_dic[service.id]['index_data'][index.key] = {
'id': index.id,
'name':index.name,
'data':[]
}
#else: #like nic service
'''
print(service_data_dic)
#service_data_dic
#開始取數據
for service_id,val_dic in service_data_dic.items():

service_redis_key = "StatusData_%s_%s_%s" %(self.host_id,val_dic['name'],self.time_range)

return service_data_dic
