This one is not finished but this is a first draft

In agent configuration on the node add this:
[ExternalTable/PBSBackup]
Command = proxmox-backup-manager task list --all --output-format json-pretty | jq -r '(map(keys) | add | unique) as $cols | map(. as $row | $cols | map($row[.])) as $rows | $cols, $rows[] | @tsv'
Separator = \t
InstanceColumns = Index
Description = Proxmox backup server status
PollingInterval = 320

Do a restart agent and then a config poll.

After that you should be able to go to Data Collection Configuration on that node and add a new Table.

Thank you for the Draft !
If this is your first time 

You will need to install on your Proxmox Backup Server

apt install jq

ELSE you will get this in the Last Value on PBSBackup

If you try the command on the command line
PVE-PBS-Server# proxmox-backup-manager task list --all --output-format json-pretty | jq -r '(map(keys) | add | unique) as $cols | map(. as $row | $cols | map($row[.])) as $rows | $cols, $rows[] | @tsv'

-bash: jq: command not found
