Nagios
將戴爾開放式管理外掛與 Nagios Core 一起使用；找不到伺服器
我正在嘗試使用 Dell OpenManage 外掛監控 Dell R730 伺服器（https://www.dell.com/support/article/uk/en/ukbsdt1/sln311076/dell-emc-openmanage-plug-in-for- nagios-core?lang=en）。我已經建構了它，它似乎可以在我用於 Nagios Core 安裝的 Raspberry Pi 上執行。我可以使用桌面上的 Openmanage 實用程序連接到伺服器，並且可以使用 rpi 中的 SNMPwalk 從伺服器（打開的埠 161）獲取資訊，使用命令
snmpwalk -v1 -cpublic <ip_address>它也適用於 -v2c 選項。但是，當我嘗試時，
python dellemc_nagios_discovery_service_utility.py --host=<ip_address> --snmp.version=2 --output.file=/usr/local/nagios/dell/config/objects/它無法找到伺服器，但似乎可以工作；
Dell EMC device discovery is in progress... Total no of Hosts / IPs provided :1 Total no of Hosts / IPs processed successfully :0 Total no of Hosts / IPs already discovered:0 Total no of Hosts / IPs processing unsuccessful:1Dell EMC 設備發現已完成。
我使用了此處的說明，但無法獲得適用於 Raspbian 的 Dell RACADM deb 版本。它們有點舊，但我完成了大部分工作。
該外掛建構良好，我使用 pip 安裝了 OMSDK。以上命令均未使用 sudo 執行，就像 pi 使用者而不是 nagiosadmin 一樣。這是安裝階段的輸出；

解決了這個問題，需要使用 OSMA 登錄伺服器，設置 iDrac 並在打開警報後使用上面命令中的地址和 snmp.version=2。
