Startup Telegraf

systemctl start telegraf
systemctl enable telegraf

Configure InfluxDB

Set the retention policy

influx -execute 'alter retention policy "autogen" on "vmware" duration 200d shard duration 1d'

Deploy the OVA to vCenter/ESXi

部署到 ESXi 6.5 時失敗，錯誤訊息

Line 163: Unable to parse 'tools.syncTime' for attribute 'key' on element 'Config'.

解決方法: 使用 OVF-Tool 先解開 OVA 檔，編輯 OVF 檔的內容

# Before
<vmw:Config ovf:required="true"  vmw:key="tools.syncTime" vmw:value="true"/>

# After
<vmw:Config ovf:required="false"  vmw:key="tools.syncTime" vmw:value="true"/>

存檔後，重新再部署一次。

First to Start the VM

1. SSH Credential: root / Sex!Gr@f

2. Need to manually configure the IP, Edit the /etc/network/interfaces .

3. Configure the hostname

hostnamectl set-hostname esx-mon

4. Configure the timezone and time server

timedatectl set-timezone Asia/Taipei

vi /etc/ntp.conf

#pool 0.ubuntu.pool.ntp.org iburst
#pool 1.ubuntu.pool.ntp.org iburst
#pool 2.ubuntu.pool.ntp.org iburst
#pool 3.ubuntu.pool.ntp.org iburst

# Use Ubuntu's ntp server as a fallback.
#pool ntp.ubuntu.com

# Added the local time server
server 192.168.21.86 prefer iburst

Restart the ntpd

systemctl stop ntp
systemctl start ntp

# Check the timeserver
ntpq -p
