How to check HAProxy stats?

How to check if HAProxy is working or not?

I have a HAProxy running on my server and I am trying to check if it is working or not.

I have an IP that goes through the HAProxy to a server. When the server is up, the IP should be redirected to a page on a server which I own. But when the IP is not redirected to the page, I can't see the error message in the console.

I need to check if HAProxy is working or not. Is there a way to check it? It is easy. In your HAProxy configuration file, just add a virtual server with an error message. Something like this. Http-request deny if. Also make sure to set a timeout so that the connection will be dropped after 30 seconds. Http-request timeout 30. I hope this helps you.

What is the default port for HAProxy stats?

I configured my HAProxy server to collect stats, and then tried to go to a webpage to check the server stats and got a 404 not found.

The port that I configured for stats is port 8080, but when I enter the IP of the server I think it's sending this port along with it. However, when I send a request for HTTP stats it seems the default port is 80.

Also, I have another question. If I enable stats for another server, does that change the other default stat port? If your service has no public-facing IP address (as opposed to just one IP address), I would guess that port 8080 (or whatever it is) is being used by some kind of firewall or load-balancing service that the HAProxy is acting as a client/server. So, the default port on a HAProxy server is most likely just port 80 on that same address.

AFAIK, HAProxy doesn't have a configuration option for specifying a different port, so you'll probably have to adjust it with ifconfig.

How to check HAProxy stats?

I am trying to check HAProxy stats (like total connections, time outs, etc.) for each node in our cluster. If I ssh to a server and type:
Root@web01:/opt/haproxy/1.4/bin# haproxy -s it will display the stats for ALL nodes (which is what I would expect). If I look at the top level of my logs (/var/log/haproxy/) I see: The 12898 shows up for each node, and it's listed as a single instance, meaning there's one stat per node, but when I try to see the number of servers (Total Connections), it seems to display all the stats again (12898) as if it's doing the math on a single stat total, rather than on a single node. How can I tell which stats are per node? (Total Traffic and Total Connections is what I am most concerned with.) Thanks! For each machine, you need to run the command separately as a different machine. For example, on machine 2 of the cluster (say, web2), run the command on machine 1 of the cluster (web1).
