Monitor the CPU temperature of raspberry pie 4B installed with esxi on ARM

In traditional x86 Server ,ESXi You can monitor the server cpu temperature , Pictured ：

cpu Temperature display

We usually play raspberry pie , You can get cpu temperature , And you can start and stop the fan through the program .( There are many tutorials on the Internet )

When ESXi on Arm Installed in raspberry pie 4b in the future , By default, the temperature cannot be obtained .

A few days ago, a netizen was https://github.com/thebel1/thpimon Provided in thpimon-0.1.0-1OEM.701.1.0.40650718.aarch64.vib This drive , stay ESXi on Arm Install this vib After driving , You can go through python Script to get the corresponding data . The specific steps have been included in the description of the above project . I won't demonstrate the steps here . look down python The display result of the script ：

Running results

Although the problem of data collection is solved here , However, time series data cannot be formed , Then we need to continue to transform python Script to achieve , There happens to be another https://github.com/fgrehl/esxi-raspi, Based on the former, the generation of time series data is realized .

Set up interval Grab ：

Set up interval, Default 10S, It can be modified through parameters

Just in Console Print time series data in , Obviously, it can't reach “ monitor ” Level , So we added sending data to Graphite The host CARBON port , So you can do it Graphite The front-end graphically displays time series data .

Set the sending host ：

Parameter setting

Because it involves from ESXi outward (CARBON) send data , You can try to turn off the firewall ：esxcli network firewall set --enabled false, In an important environment , Please set firewall rules for this behavior separately , Don't turn off the whole .

Look at the runtime Console Display of ：

send data

You can see that the format is index , data , Time

Graphite The construction of the host is not explained in detail , You can refer to https://graphite.readthedocs.io/en/latest/install.html adopt Docker Install and run , I am in a virtual machine Photon OS This Docker, Stop by Amway here Photon OS, It's great for playing Docker.

visit Graphite webui:

A tree structure

From the tree structure Metrics Next, find the data we sent .

double-click cputemp You can display the graph on the right , And can customize some attributes of graphics .

besides , We can still do that Dashboard Add this indicator , If there are multiple machines or multiple indicators , We can define what we want Dashboard：

After the save , This access address http://192.168.1.235/dashboard/ESXi-pi2%20cputemp%20Dashboard You can visit it at any time later .

Seen from the figure , This period of time should ESXi on Arm Run raspberry pie 4b Of cpu The temperature is basically 46-48.5 Between degrees .
