[검증] zabbix-server4.0에서 zabbix2.2 계열의 zabbix-agent를 그대로 사용할 수 있습니까?

개요

zabbix2계의 agent를 그대로 사용해 zabbix-server4.0으로 값 취득할 수 있는지의 검증입니다.
이번에는 zabbix4.0의 디폴트인 템플릿 「Template OS Linux」를 사용하고 있습니다.

환경

OS: amazonlinux2
미들웨어
- nginx 1.16.1
- php 7.3
- mysql 8.0

결론

결론부터 말하면 문제없이 값을 얻을 수있었습니다!
- CPU
- RAM
- DISK(LLD)
- 네트워크(LLD)
아직 검증 도중이므로, 다른 검증했을 때에 갱신합니다.

이하 환경 구축에 쓰고 있습니다만, php7계라면 「zabbix-web-mysql」을 할 때 yum으로부터 인스톨을 할 수 없기 때문에 주의가 필요합니다.

■ 검증 결과

■agentバージョン
# zabbix_agent -V
Zabbix agent v2.2.23 (revision 83227) (30 July 2018)
Compilation time: Jul 30 2018 10:34:32

■zabbix4.0의 GUI

환경 구축

zabbix-web-mysqlをyumでインストールすると依存関係でphp-mysqlをインストールしようとするがphp7.3系では「php-mysql」は「php-mysqlnd」になったためconflictsしてしまう。
解決策「zabbix-web-mysql」パッケージは別でインストールする。「php-mysqlnd」が入っていれば問題なし。

■zabbix-web-mysqlを別にインストールする。
yum install zabbix-server-mysql zabbix-web-japanese
