Hi,

You can use scur metric like this: haproxytool server -D <dir_path> -m scur <server>

From HAproxy documentation:

4. scur [LFBS]: current sessions

tnx @unixsurfer

when i use of nbproc in haproxy , better use of one single socket file for all cpu cores ? or use of separate files for each cpu core?

[unixsurfer]

You need to bind each HAProxy process to a different UNIX stats socket, and then use -D argument to point to the directory with all UNIX stats socket files.

@unixsurfer hi again

I bind each HAProxy process to a different UNIX stats socket, and then use -D argument to point to the directory with all UNIX stats socket files.But when run this command :

haproxytool server -D /var/lib/haproxy -m scur nginx-b-dev

It does not display anything! below is output :

But when I run this command it's working :

https://paste.fedoraproject.org/paste/PXBpnxFW31G-T2nDocNn2F5M1UNdIGYhyRLivL9gydE=

Is something wrong?

tnx

Hi @hos7ein,

In the first case you gave the server name and you got back the current sessions only of that server. In the second case you didn't pass a server name and therefore the tool return the requests served by all servers.

So, the tool worked as expected.

Could you please read the help of server ( haproxytool server --help) command and let me know which part isn't clear to you?

Cheers, Pavlos

tnx @unixsurfer for response

Imaging “nginx-b-dev” is server name in “nginx-dev” backend. How can I see real time request on “nginx-b-dev” server?

Thank you

[unixsurfer]

you can do it with: haproxytool server -r --backend=nginx-dev nginx-b-dev

Please read the help message from information.
