@AreaScout, Just started using your LCD Info and Monitoring Tool on Ubuntu 18.04 minimal. Very nice indeed! Thanks for sharing your wonderful work!
Thank you :)

@all

New version 1.0.12-1 is online:

cloudshell2 LCD display and monitoring tool 1.0.12

New config file ! before installing please remove any older version with sudo dpkg -r cloudshell2-monitoring don't forget to backup your current config before
  • Add possibility to use unique table names for grafana datasource, so multible cloudshell's can be monitored at once
  • Fix rebuild value positioning, moved it more to the right
Have fun :)

Hi awesome monitoring tool!
Installed it and works like a charm.

3 questions:

1. How did you get both HDMI and the LCD working to nice without issues?
Using the default lcd tool supplied by odroid it is a hassle to have dual screen needing to work on Xorf.conf etc.

2. I am using 2 separate drives. So not in RAID mode. Would it be possible to change the GUI to show 2 times free space?

3. Is it possible to change the poll interval for the different metrics somewhere? Can't see anything in the conf file for it.


Thanks!

  1. Those are two different devices with two different input buffers, so one Application writes on HDMI and the other Application on the LCD, it's just that easy, no xorg.conf where a xserver tries to write on two devices at the same time
  2. The space is limited on the LCD so no there will be no free space showed for the second disk, why you guy's are not using the RAID controller, it's like buying a car and use it as bicycle ???
  3. Nope you can't change that and why you would ? The app takes only 0.45% CPU usage in AVG, although the next release will contain documentation how long this intervals are, i.e for asking the RAID status each ~1min
P.S.: The RAID controller is monitoring your hard disks for health and it will keep you informed if something is not working, also it provides a fail save and data recovery process while you still can access your data so why not using it ? It let's you read SMART data from both disk in a RAID configuration. :?:

@AreaScout: you're going to hate me, but you can display individual disk parameters one at a time... One polling cycle display disk 1, the next cycle disk 2.

No I do not hate you, the Idea is good, but I don't want to loop through a mass of hard disk partitions, because one disk can have of course multible partition, instead you can choose that partition which is the important one for you and configure this to show it by the tool, I think this is better and LVM device naming would make it even more difficult.

hey Areascout,

In the past I have had issues with drives on hardware raid, where none of the disk where readable anymore. Hotswapping and stuff which didnt work as advertised.

Also when enabling the jmicron Raid, I am afraid that if not the disk, but the XU4/CloudShell hardware fails, for example cpu issue of whatever, then I can no longer just remove the HD from the box and connect it to another pc to get access to my data.

When just using plain drives I can still hook them up to other hardware and read them.

General rule on RAID stages based on capability of the CloudShell2 RAID controller:
RAID0: no data recovery is possible, if a hard disk is defective you will lose all your data, but it's fast, for example if you have a database running on your CS2 the write/read speed will increase
RAID1: this is with data recovery and utilizes mirroring technique, increases read speed in some cases, and provides fault tolerance in the loss of no more than one member disk. You can limit the chance that both hard disk fail at the same time if you order i.e one WD red from Amazone.com and the second one from Jet.com so you can be sure that the hard disk's are not from the same production batch

If the CPU is defektive just exchange the XU4 -> no data lost
If the RAID controller fails just exchange the RAID controller -> no data lost

Only with RAID0 you can't hook them up to anther hardware, with RAID1 you can, just set the DIP switch to PM before booting, then boot and hold the RAID config button until the board is up and running and you have two identical disk's with the same contains running on any other hardware

P.S.: To secure your data even more against data lose you can connect a third disk via USB and make a backup once in a week or so
