Cloud Monitoring Agent Guide-linux Edition

Attention:

1, in the server monitoring cloud monitoring services do not need to access your server, only need your server to access the 42.120.78.0/24 section of the 80 port can!

2, what is the agent authentication string? The agent authentication string is a string of 32-bit encrypted authentication keys that you need to enter when you install the Cloud Monitoring agent on the server, and the monitoring service takes effect only if you enter the correct string when you install the agent to ensure that the agent can connect to the server.

First, the Installation Agent

1, download the installation package

Select the appropriate cloud Monitoring Agent RPM installation package to download the installation according to the operating system version (32-bit or 64-bit). (Cloud Monitoring Agent installation package download)

The getconf long_bit command can be used to see if the operating system is 32-bit or 64-bit, as follows:

[root@aliyun]# getconf Long_bit64

Observing the above results, the test system is 64-bit, so choose the 64-bit RPM installation package to install. For 32-bit, select the 32-bit RPM installation package.

2. Installation Agent

1, the installation under the Debian,ubuntu system

[root@aliyun]# rpm-ivh jiankongagent.x86_64.rpmPrepareing ... ############################### [100%]1:jiankongagent ############################### [100%]

The execution jiankongagent.x86_64.rpm does not have an error indicating that the installation was successful, as above.
