Monitoring Snapshot and Replication Tasks in TrueNAS

[DoItAgainSteelyDan]

Hello, looking for someone familiar with monitoring replication tasks in TrueNAS.

I enabled SNMP/SSH.

I set up SSH key authentication from zabbix to truenas

ssh- keygen - t rsa - f ~/.ssh/truenas_key - N " "
ssh- copy- id - i ~/.ssh/truenas_key.pub
USER@TRUENAS_IP

A script was created to check replication status on truenas

sudo nano /usr/lib/zabbix/externalscripts/check_replication_status.sh
#!/bin/bash
ssh - i /home/zabbix/.ssh/truenas_key - o StrictHostKeyChecking=no
USER@TRUENAS_IP \
' midclt call replication.list | jq " [.[] | select(.status != " FINISHED" )] | length" '

I made the script executable

sudo chmod +x /usr/lib/zabbix/externalscripts/check_replication_status.sh

I moved the key so zabbix can access it

sudo mkdir - p /home/zab/.ssh
sudo cp /home/zbtest/.ssh/truenas_key /home/zab/.ssh/
sudo chown zabbix:zabbix /home/zab/.ssh/truenas_key
sudo chmod 600 /home/zab/.ssh/truenas_key

Edited the sudoers file manually from truenas shell so that sudo is working for root.

I then create a snapshot and replicaiton task in TrueNAS

I test the replication by querying it with midclt call replication.query in TrueNAS shell which works perfectly.

I created a zabbix item as SSH agent with public and private key. Zabbix tells me this is not supported.


I also made sure the ownership and permissions were correct

sudo chown - R zabbix:zabbix /etc/zab/ssh_keys
sudo chmod 700 /etc/zab/ssh_keys
sudo chmod 600 /etc/zab/ssh_keys/truenas_id_rsa
sudo chmod 644 /etc/zab/ssh_keys/truenas_id_rsa.pub

I am able to SSH into the truenas server via Zabbix terminal, and run the command for an output of 0 or 1 (1 meaning success, 0 meaning fail)

However, it does not give this output when checking Monitoring --> Latest Data


Any help would be greatly appreciated.

Hi,

You did set the SSHKeyLocation parameter in the server config ?
