Monitoring (1): (cactizabbix)

Prerequisite: cacti configuration is complete

Cacti monitors other hosts (collecting data: crontab timing call (poller.php) snmp collects and stores data: rrdtool-- > rrd database under rra (fixed size, cyclic recording data, will not increase Continue to update the data later) draw the chart: http (80)-- > php-- > mysql (premise: initialize the data)-> web (php dynamically goes to the mysql database to get the information, but the real collected data is saved in the rrd mysql is the information of all nodes (except the collected information is saved in the mysql)) when the image is actually drawn Defect of calling rrdtool command cacti: no alarm, no monitoring of hardware (eg: temperature sensor, etc., but plug-ins can be installed)

Installation of monitored host: net-snmp net-snmp-utils

Vim/etc/snmp/snmpd.conf

Test:

Snmpwalk-v 1-c public localhost.1.3.6.1.4.1.2021.10.1.3

Snmpwalk-v 1-c public 172.25.42.250.1.3.6.1.4.1.2021.10.1.3

The monitored host will join the cacti

Monitoring by second: crontab+sleep

Eg:* sleep 10 commit

Eg:* sleep 20 commit

Eg:* sleep 30 commit

Eg:* sleep 40 commit

Eg:* sleep 50 commit

Monitor the local machine:

Rpm-ivhzabbix-agent-2.4.5-1.el6.x86_64.rpm

Vim / etc/zabbix/zabbix_agent.conf

/ etc/init.d/zabbix-agent start

View:

Dd4:

Rpm-ivh zabbix-agent-2.4.5-1.el6.x86_64.rpm

Vim / etc/zabbix/zabbix_angent.conf

/ etc/init.d/zabbix-serverstart

Two modes: (both hosts can be discovered automatically)

Automatic detection: (suitable for batch processing)

Auto load: (higher availability)

Monitor mysql services on server

How zabbix agent gets mysql is specified in the / etc/zabbix/zabbix_agentd.d/userparameter_mysql.conf file

All kinds of information about the service, and create a new ".my.cnf" file in the / var/lib/zabbix directory to specify how zabbix agent logs into the database. By default, the zabbix user is used, and the password can be found in the zabbix_server.conf file.

# mkdir/var/lib/zabbix

# vim / var/lib/zabbix/.my.cnf

[mysql]

Host = localhost

User = zabbix

Password = westos

Socket = / var/lib/mysql/mysql.sock

[mysqladmin]

Host = localhost

User = zabbix

Password = westos

Socket = / var/lib/mysql/mysql.sock
