Asura Monitoring is used in combination with grafana

Environmental preparation

First, install grafana

Create the installation directory as you are used to, and this article is in the current directory

# cd # wget https://s3-us-west-2.amazonaws.com/grafana-releases/release/grafana-4.3.2.linux-x64.tar.gz-- no-check-certificate # tar xzvf grafana-4.3.2.linux-x64.tar.gz # cd grafana-4.3.2/conf/ # vim defaults.ini Major changes to the database where the configuration database information is consistent with the Asura system database information

[database]

Type = mysql

Host =

Name =

User =

Password =

Url = mysql://monitor:aZkl299feM@os.dbm.com:3306/cmdb

Asura configuration information is available in

# cat / home/runtime/tomcat_8081/webapps/ROOT/WEB-INF/classes/jdbc.properties

Please pay attention to the information.

Jdbc.mysql.monitor.url.master=jdbc:mysql://os.dbm.com:3306/cmdb?useUnicode=true&characterEncoding=UTF-8

Jdbc.mysql.monitor.username.master=monitor

Jdbc.mysql.monitor.password.master=aZkl299feM

Start grafana

When cd grafana-4.3.2/bin/# starts in this way, the foreground starts, and the process is gone after the terminal shuts down. / grafana-server # you can use nohup to run nohup. / grafana-server & in the background

Then the installation of grafana is complete.

Visit grafana

Http:// your server address: 3000 will be able to access grafana

Like http://10.10.10.10:3000.

The default username and password are all admin

Configure Asura to access the url of grafana

Modify the Asura configuration file or add environment variables

Modify Asura configuration file

Vim / home/runtime/tomcat_8081/webapps/ROOT/WEB-INF/classes/system.properties

Add the following configuration to the file to save and restart the Asura tomcat service

GrafanaServer= http://10.16.35.193:3000/

# write the following configuration to / etc/profile using environment variable access

Export grafanaServer= http://10.16.35.193:3000/

Source / etc/profile

# restart the Asura tomcat service

Query data supported by Asura

Query condition support is used when making templates

Query Options

Query:

1. Multi-conditional query

The operation and maintenance group is used to query the business line. The ip address is 10.16.35.*, and the hostname contains the machine of os_.

[{"groups": "Application Operations Group"}, {"ip": "10.16.35?"}, {"hostname": "os_"}]

2. Specify an IP address

{"ip": "10.16.35.100"}

3. Check the value at the beginning of an IP address

{"ip": "10.16.35?"}

{"ip": "10.16.35.1?"}

{"ip": "10.16.?"}

4. Check the line of business

{"groups": "Application Operation and maintenance Group"}

5. Check the hostname of

{"hostname": "os_"}

Query syntax for metric

Indicator group | in the metric name, $host, (data acquisition type)

Example:

Loadavg | system.load.1,10.16.35.100 queried 10.16.35.100 metric data named system.load.1

In the grafana configuration template, add the host variable

Loadavg | system.load.1,$host then you can use variables to pass the ip address

Query the most recent piece of data

Loadavg | system.load.1,$host,last returns the result of the most recent metric in system.load.1

Loadavg | system.load.1,$host,max returns the maximum value within the specified query period

Loadavg | system.load.1,$host,min returns the minimum value within the specified query period

Loadavg | system.load.1,$host,count returns the number of data entries within the specified time period

Loadavg | system.load.1,$host,sum returns the summation result of the data within the specified time period

Loadavg | system.load.1,$host,avg returns the aPCge result of the data within a specified time period
