OVH Guides

What are the IP addresses of the OVH monitoring ?

Find here the IP addresses to fill in when setting up a firewall so that OVH monitoring will continue to work on your server.

Requirements

The monitoring service allows OVH to monitor the status of your machine and automatically trigger the intervention of a technician in the datacenter.

All the servers of our customers and the entire network are monitored 24/7 by OVH technical teams.

OVH intervenes as soon as an alert (non-response to the pings) is triggered in order to minimize the downtime of the servers and the network.

To implement a restrictive firewall, especially on ICMP, and continue to benefit from OVH monitoring, it is necessary to authorize the IPs that you will find below.

To do this, you must have :

  • An OVH product on which you have installed a Firewall.
  • Have access to the Firewall rules.

Communication between the RTM service and your server also requires that you allow inbound and outbound connections on UDP ports 6100 through 6200.

If your server is located in Roubaix 3, you have to retrieve the last IP via tcpdump.

 root@nsXXXX:# tcpdump host server.ip | grep ICMP 

Enable/Disable Monitoring

First, log in to the OVH Control Panel. On the left-hand tab select the Dedicated Server in question from the Dedicated servers drop-down menu.

Service_Status

In the Server status tab, click the Enable or Disable button next to "Monitoring". Click Confirm on the popup window to confirm the changes.

Enable Monitoring of Specific Services

In addition to the standard Monitoring, you can enable OVH to monitor specific services such as HTTP, SSH, and other protocols in the OVH Manager. To do this, click Monitor my services under the "Service status" section on the Server status tab. Click Monitor a service and you will be taken to the following screen:

Monitoring

Enter the IP address, protocol, port number, server response, and the time interval between checks on your service and press the check mark to confirm the changes.

Conclusion

OVH Monitoring offers our customers a variety of ways in which OVH can provide information about the status of your Dedicated Servers. We highly recommend that you take advantage of these free services.
