Zabbix monitoring system practice

This article shares zabbix’s specific operation and practical objectives of system software and hardware monitoring, but does not describe the specific application construction of secondary development. In fact, after reading this article and knowing their own skilled operation, ordinary programmers will have specific implementation plans for secondary development.

1. Prepare documents

2. Install and compile zabbix server.

CD /usr/local/src/zabbix /** Start MySql**/ mkdir.. RPM -bundle.tar -c /usr/local/ SRC /MySql/ CD.. /MySql/ Chmod a+x MySql -* /* All mysql server first preinstallation relevant delete * * / RPM - aq | grep mysql Yum - remove mysql - libs * y/install their own version of * * * * / RPM - the ivh RPM RPM -ivh mysql-client-5.1.1.glibc23.x86_64.

Or (when the above operation encounters error obstruction)

cd  /usr/local/src/zabbix/tools/net-snmp-devel
rpm -Uvh --force --nodeps *.rpm
cd /usr/local/src/zabbix/tools/libevent-devel

SNMP Third-party hardware device monitoring.

CD/usr/local/SRC/zabbix/tools/SNMP - 5.7.3. Tar ZXVF.net - tar. Gz - C/usr/local/SRC/CD. /.. /./configure --prefix=/usr/local/ SNMP Make && Make install vim /etc/profileCopy the code

Source /etc/profile
Copy the code

Note: SNMP monitors the common OID of third-party devices.

Here, IKuai soft routing is used to simulate third-party switch devices. Open the switch configuration page and enable the SNMP function.

The SNMP parameter values of the device model are obtained from the official website.

Add a host group.

Enter the host group name.

Added monitoring templates.

Enter the name of the monitoring template and the bound host group.

Find the newly added template and click in to configure monitoring items.

Go to Items -> Create Item.

Test several memory OID in IKuai with SNMPWalk to confirm that the server SNMP is ok.

Continue to configure monitoring parameters and confirm that the Settings are saved.

Configure the OID to be monitored based on the preceding figure. Four NEW OID monitoring items are added here.

Click Graphs -> Create GRAPs.

Select the monitoring item that you want to draw a diagram for and save it.

Click to select a monitoring server.

Configure the SNMP device address.

Bind templates to monitored hosts.

Confirm, add templates, update.

Wait a few minutes and check that SNMP is green.

Click Monitoring -> Graphs -> IKuai MemoryStatus to see switch usage information.

Note: SNMP monitors the private OID of a third-party device

1. Prepare the official private MIB file.

net-snmp-config --default-mibdirs
Copy the code

cd /usr/local/snmp/share/snmp/mibs/
cp /usr/local/src/zabbix/conf/ikuai-mib.txt /usr/local/snmp/share/snmp/mibs/
Vim ./ikuai-mib.txt
Copy the code

snmptranslate -Tz -m IKUAI-MIB | column -t | head
Copy the code

Snmpwalk -v 2c -p public 192.168.77.1 1.3.6.1.4

Disk I/O Monitoring

yum install sysstat cp /usr/local/src/zabbix/zabbix_scripts/chk_disk_status.sh /usr/local/zabbix/scripts/ cd /usr/local/zabbix/scripts/ chmod a+x chk_disk_status.sh vim .. /etc/zabbix_agentd.confCopy the code

killall zabbix_agentd
service zabbix-agent start
Copy the code

Added a monitoring template.

Enter the template name and host group.

Click the newly created monitoring template.

Go to Items -> Create Item.

Configure Name and Key.

Configure all monitoring items based on the preceding picture. Dist. Status [1,1,1,2] 1= disks,1 = disks,1 = disks,2 = monitoring items.

Create a chart.

Enter a chart name, select all monitoring items, and finish.

Select a monitor host, click Template, Link new Template and select the newly created Template.

Key script code

The following is the shell script code needed to complete the monitoring work in the process of the above operation, posted below, together with the reference, if you need my directory structure full package file, you can private letter myself, see the letter, will be private letter sharing.
