<td>10.1.1.2</td>
<td>10.1.1.3</td>
Matching treatment is carried out with regular expression, each take out is appended in list, list is finally obtained
[‘10.1.1.1’,’10.1.1.2’,’10.1.1.3’…..]
IP in list is the IP address of the server in current parsing pond.This list is saved, for detecting module
Fixed IP is detected.
Detecting module is used for after receiving the IP address list that IP address generation module is sent, first by the more of python
Threading models create a sub thread, this sub thread is detected using two ways:
The first: call python pycurl module (this module dedicated for HTTP request detection, detection can be collected
The links response time in the process, such as DNS time, TCP build connection time, download time), main thread first with
For circulation is that each sub thread takes out detection IP, pycurl a sending probe requests thereby in IP list, detection process is obtained
To the corresponding temporal information of each link be stored in predefined variable；
Second: ping test being carried out to the IP address of network node, probe command ping-f-c 1000 is quickly sent out
1000 ping tests out obtain packet loss with packet loss number/1000.
Detecting module is also used to the alarm decision to network node, specifically, if the total duration of this probe requests thereby is not
More than 10 seconds and the packet loss of ping was less than 10%, then terminated the detection process of the sub thread；In case of probe requests thereby 10
Whether second time-out or packet loss are more than any situation in 10%, then " frequency of failure "+1, judge " frequency of failure " more than 3
Secondary, if being also less than 3 times, this exception is " doubtful alarm ", the suspend mode of this thread 10 seconds, is detected again；If " failure time
Number " is more than 3 times, then this exception is " true alarm ", and detecting module is surveyed with the last time that pycurl test process retains
Information variable, the ping packet loss of examination, generate a dictionary, and the format of dictionary is exemplified below:
{ ' IP ': ' 10.1.1.1 ', ' CDN ': ' chinacache ', ' ping_lost ': ' 0% ', ' time_totle ': '
11s’,’time_dns’:’1s’,’time_connect’:’10s’…}
Most contents can be used to generate the detection details content in warning message in next step in the dictionary.
Alarm module is then IP service performance the case where having IP address detection continuous 3 times more than 10 seconds when being triggered
There may be exception, need to report first to be read out the dictionary that previous step generates to website operator, obtain alarm IP, CDN
Then title, detection time details call " nali " tool to detect this IP ownership place in shell, next start to arrange lattice
The exquisiteness that identification module and detecting module obtain is organized into one section of bell character(BEL) string, character string citing by formula:
[IP:10.1.1.1 state: alarm]
Ownership place: China-Beijing
CDN service quotient: chinacache
Detect details:
time_totle:11s
time_dns:1s
time_connect:10s
time_download:0s
Ping_lost:0%
Service calls: 010-******
Alarm module calls monitored module in shell, this character string is sent to monitor terminal, which exists
It is configurable in configuration file.
