Troubleshooting Steps if the Monitoring Data is not visible
===========================================================================

All E2E Nodes are Pre-configured for Monitoring by default, This data are available to you on the Monitoring section In Manage Node page. Post Launching your Nodes, You will be able to view this data within 5 to 10 Minutes.

Sometimes, This data might not be visible to you or might stop seeing the data completely from the Monitoring Dashboard. In this article, we will share with you some of the common steps to troubleshoot the issue to fix this issue from your end.

Step1: Make sure Zabbix-agent is running
````````````````````````````````````````````
E2E Nodes by default are configured for Monitoring via Zabbix-agent. This agent will be running on your server when you Launch your Nodes, You need to make sure this agent is running all the time so that your servers are being monitored continuously

You can check the status and Verify it by running below command

::

        service zabbix-agent status

If you see service has been stopped for some reason, Please start the service with below command

::
        
        service zabbix-agent start

Step2: Zabbix Port should be opened on your server

Even if the Zabbix-agent is running fine on your server, the E2E Cloud Monitoring server should be able to Fetch the data from your server to display in Myaccount Portal. You need to verify and Keep Open the Zabbix-agent Port 10050 to E2E Cloud Monitoring server (172.16.103.23)

To open the Zabbix port **10050** to the E2E Cloud Monitoring server, Please use the below command.

::

        sudo iptables -A INPUT -p tcp -s 172.16.103.23 --dport 10050 -j ACCEPT

Here we use Iptables which by default installed and configured on E2E Nodes, If you have configured some other firewall you need to open the port accordingly.

Once the above command is run, You need to reload IPtables rule, Please refer below and use the appropriate command as per your OS.

On Ubuntu 14.04 use the following commands to save/reload the iptables rules

::

        sudo /etc/init.d/iptables-persistent save

        sudo /etc/init.d/iptables-persistent reload

On Ubuntu 16.04 and Ubuntu 18.04 use the following commands

::

        sudo netfilter-persistent save

        sudo netfilter-persistent reload

If you are using centos, Use Below command

::

        service iptables save

Apart from Above steps, You will also not be able to view the Zabbix data on the below scenarios

- Custom Image
- Your Node is powered off
- Your Node is Unreachable
- Zabbix-agent service has been uninstalled on your node
- Manual Changes made on Zabbix Configuration from your end.
