If -f argument is a directory add all the files (and only files) it
containes to the config files list.
These files are added in lexical order (respecting LC_COLLATE).
Only files with ".cfg" extension are added.
Only non hidden files (not prefixed with ".") are added.
Symlink are followed.
The -f order is still respected:
$ tree -a rootdir
rootdir
|-- dir1
| |-- .6.cfg
| |-- 1.cfg
| |-- 2
| |-- 3.cfg
| |-- 4.cfg -> 1.cfg
| |-- 5 -> 1.cfg
| |-- 7.cfg -> .
| `-- dir4
| `-- 8.cfg
|-- dir2
| |-- 10.cfg
| `-- 9.cfg
|-- dir3
| `-- 11.cfg
|-- link -> dir3/
|-- root1
|-- root2
`-- root3
$ ./haproxy -C rootdir -f root2 -f dir2 -f root3 -f dir1 \
-f link -f root1
root2
dir2/10.cfg
dir2/9.cfg
root3
dir1/1.cfg
dir1/3.cfg
dir1/4.cfg
link/11.cfg
root1
This can be useful on systemd where you can't change the haproxy
commande line options on service reload.

This was reported in HTML dumps already but not CSV. It reports the
number of monitor and stats requests. Ideally use-service and redirs
should be accounted for as well.
Frontends have extra information compared to other entities, they can
report some statistics at the connection level while the other ones
are limited to the session level. This patch adds 3 more fields for
this :
- conn_rate
- conn_rate_max
- conn_tot
It's worth noting that listeners theorically have such statistics, except
that the distinction between connections and sessions is not clearly made
in the code, so that will have to be improved later.
The server's cookie value is now reported in the "cookie" column and
used as-is from the HTML dump. It was the last reference to the sv
pointer from this place.
The same was done for the backend's dump.
This new field "addr" presents the server's address:port if the client
is either enabled via "stats show legends" in case of HTTP dumps, or
has at least level operator on the CLI. The address formats might be :
- ipv4:port
- [ipv6]:port
- unix
- (error message)
This adds the following fields :
- check_rise [...S]: server's "rise" parameter used by checks
- check_fall [...S]: server's "fall" parameter used by checks
- check_health [...S]: server's health check value between 0 and rise+fall-1
- agent_rise [...S]: agent's "rise" parameter, normally 1
- agent_fall [...S]: agent's "fall" parameter, normally 1
- agent_health [...S]: agent's health parameter, between 0 and rise+fall-1
Added these two new fields to the CSV output :
- check_desc : short human-readable description of check_status
- agent_desc : short human-readable description of agent_status
Also factor two tests for enabled checks.
The agent check status is now reported :
- agent_status : status of last agent check
- agent_code : numeric code reported by agent if any (unused for now)
- agent_duration : time in ms taken to finish last check
Using environment variables in configuration files can make troubleshooting
complicated because there's no easy way to verify that the variables are
correct. This patch introduces a new "show env" command which displays the
whole environment on the CLI, one variable per line.
The socket must at least have level operator to display the environment.
When memmax is forced using "-m", the per-process memory limit is enforced
using setrlimit(), but this value is not used to compute the automatic
maxconn limit. In addition, the per-process memory limit didn't consider
the fact that the shared SSL cache only needs to be accounted once.
The doc was also fixed to clearly state that "-m" is global and not per
process. It makes sense because people who use -m want to protect the
system's resources regardless of whatever appears in the configuration.
This commit adds support for setting a per-server maxconn from the stats
socket. The only really notable part of this commit is that we need to
check if maxconn == minconn before changing things, as this indicates
that we are NOT using dynamic maxconn. When we are not using dynamic
maxconn, we should update maxconn/minconn in lockstep.
This doc explains how to start/stop haproxy, what signals are used
and a few debugging tricks. It's far from being complete but should
already help a number of users.
The stats part will be taken from the config doc.
