[Xymon] Xymon server to monitor off-site cluster [private nodes]

[Root, Paul T]

Yes, you’ll be fine. The web server isn’t automatically turned on when you install the server.

Installed the client first on the head-node. It reports to my xymon server perfectly fine.

Now I installed an xymon server on the head-node, where can I disable the server daemon and enable xymonproxy? I also want to make sure that there is no xymon web server running, does disabling the xymon server daemon automatically take care of this or is there an extra step to shutting down the web server? I want everything displayed on my off-site central xymon server and nowhere else.

Thanks!

Xymon users & admins,

I write to you in seek of help for a problem that may be simple for some but I am having trouble tackling. I will try my best explain:

I wish to monitor a scientific computing cluster, these are the details:
There is a head node and 9 slave blade servers - 10 nodes total.
The slave servers are all connected to a private network, therefore
The head node has 2 active network devices - 1 for the private network, and 1 for the outer network to allow remote access to the cluster. This is the ONLY entry/outgoing point
If the slave nodes need to go out to the internet for updates, ect.. they connect through a proxy on the head node.

My xymon server is located off-site but firewall settings allow communication between the head node of the cluster and my xymon server. I am currently just probing network tests on the head node, I did NOT install a xymon client or server yet on any node of the cluster.

How can I get a report pushed / pulled to my xymon server so that I can monitor and test all aspects of EVERY NODE? I want to be able to receive hardware and custom tests as well. Do I need to setup some sort of relay xymon server on the head node, or can I just configure the xymon slave clients to use tinyproxy which is already set up on the head node?

Yes, install xymon onto the head node, make sure the xymon server is disabled, but xymonproxy is enabled, and xymon client is enabled.

Then install xymon client on the remaining 9 nodes, and set the "xymon server" as the head node internal/private IP.

Hope this helps.

Regards,
Adam
