get haproxy stats/informations via socat

You can configure a stat socket for haproxy in the global section of the configuration file:

Copy
global
  daemon
  maxconn 999
  user foobar
  stats socket /var/run/haproxy.stat  # this is the line you want to configure

You need socat to query data from this socket.

After installing socat and reconfiguring haproxy you can use this socket to query data from it:

show informations like haproxy version, PID, current connections, session rates, tasks, etc..
```
Copy
echo "show info" | socat unix-connect:/var/run/haproxy.stat stdio
```
prints the stats about all frontents and backends (connection statistics etc) in a csv format
```
Copy
echo "show stat" | socat unix-connect:/var/run/haproxy.stat stdio
```

indeed the following prints informations about errors if there are any

Copy
echo "show errors" | socat unix-connect:/var/run/haproxy.stat stdio

show open sessions with the used backend/frontend, the source, etc..

Copy
echo "show sess" | socat unix-connect:/var/run/haproxy.stat stdio
