This article mainly introduces how to achieve client-side monitoring in nagios. The article is very detailed and has certain reference value. Interested friends must read it!

Client monitoring:

In this demonstration, the three ways to monitor clients mentioned earlier are:

Method 1: SNMP

Server IP: 192.168.100.133

Client IP: 192.168.100.132

Restart client snmpd

The server-side snmp command gets client-side correlation values

Take the client's load value of 1 minute, 5 minutes and 15 minutes as an example

On this basis, we can use nagios plugins

Method 2: nrpe(here, the disk command is detected as an example)

In order to pass parameters to this method, we have added argument when compiling before; so we can make parameters on the server side,

For example:

Modify client nrpe.conf

Turn on Allow Transfer Parameters

vim /usr/local/nagios/etc/nrpe.cfgdont_blame_nrpe=1

Edit files to allow remote operations on the server side;

vim /usr/local/nagios/etc/nrpe.cfg

allowed_hosts=192.168.100.190command[check_disk]=/usr/local/nagios/libexec/check_disk -w $ARG1$ -c $ARG2$ -p $ARG3$

Initiate nrpe

/usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d

Testing on the server side:

[nagios@masterlibexec]$ ./ check_nrpe -H 192.168.100.134 -c check_disk -a "20%" "10%""/boot"

You can see that the server controls our target requirements at will

Method 3: SSH

Write your own script to get;

Method 4: Write an agent. socket fetch;

The main way to obtain is the above four ways
