Grafana, COLLECTD and InfluxDB create cool surveillance Systems (iv) Introduction to common plug-ins and custom data articles

First, the introduction of common plug-ins

Gets the connection status of the specified port established, close_wait, listen, etc.

Tcpconns:

<plugin tcpconns>

Listeningports false

LocalPort "80"

RemotePort "80"

</Plugin>

Get the status of Nginx

Nginx:

<plugin nginx>

URL "Http://test.tt.com/NginxStatus"

</Plugin>

Ping:

<plugin ping>

Host "172.18.2.125"

Interval 10.0

Timeout 1.0

</Plugin>

Get the traffic for the NIC

Interface

<plugin interface>

Interface "Eth0"

</Plugin>

The following plugin directly cancels the comment

Cpu

Load

Memory

Processes

Ii. operating the database via the HTTP API of INFLUXDB
1. Create a database
#curl-G http://172.18.1.113:8086/query--data-urlencode "Q=create DATABASE mydb"

2. Inserting data
#插入单条数据
#curl-I-xpost ' http://172.18.1.113:8086/write?db=mydb '--data-binary ' cpu_load_short,host=server01,region=us-west value=0.66 '

#一次插入多条数据提高效率
#curl-I-xpost ' http://172.18.1.113:8086/write?db=mydb '--data-binary ' Cpu_load_short,host=server02 value=0.67
Cpu_load_short,host=server02,region=us-west value=0.55
Cpu_load_short,direction=in,host=server01,region=us-west value=2.0 '

#将数据写入文件一次性插入
#curl-I-xpost ' http://172.18.1.113:8086/write?db=mydb '--data-binary @test. txt
#cat Test.txt
Cpu_load_short,host=server02 value=0.67
Cpu_load_short,host=server02,region=us-west value=0.75
Cpu_load_short,direction=in,host=server01,region=us-west value=7.0

3. Querying data
#curl-G ' http://172.18.1.113:8086/query?pretty=true '--data-urlencode "Db=mydb"--data-urlencode "Q=select value from Cpu_load_short WHERE region= ' us-west ' "

Querying using the command line

#influx > Show databases;name:databases---------------name_internalcollectdgrafanamydb> use COLLECTD; Using database collectd> SELECT * From/load/where host= ' t125 ' limit 2;name:load_longterm-------------------timehost Typevalue1456453923000000000t125load01456453933000000000t125load0name:load_ Midterm------------------Timehosttypevalue1456453923000000000t125load01456453933000000000t125load0name:load_ ShortTerm--------------------timehosttypevalue1456453923000000000t125load01456453933000000000t125load0

Third, custom monitoring data

Example: Monitoring the response time of a site

#!bin/bashtime= ' Curl-o/dev/null-s-w%{time_connect}:%{time_starttransfer}:%{http_code}--connect-timeout http:/ /www.baidu.comtime_connect= ' echo $time |cut-d ': '-f1 ' time_starttransfer= ' echo $time |cut-d ': '-f2 ' http_code= ' echo $ Time|cut-d ': '-f3 ' response_time= ($ (echo $time _starttransfer-$time _connect|bc)) curl-i-xpost ' http://127.0.0.1:8086 /write?db=collectd '--data-binary ' oss_web,url=$1,type=response_time value= $response _timeoss_web,url=$1,type=time _connect value= $time _connectoss_web,url=$1,type=time_starttransfer value= $time _starttransfeross_web,url=$1,type= Http_code value= $http _code "

Join the scheduled task one minute to execute. Then go to the Grafana drawing
