6 pmdahaproxy - HAProxy PMDA
7
9 pmdahaproxy is a Performance Metrics Domain Agent (PMDA) which extracts
10 live performance data from HAProxy statistics socket or URL.
11
12 By default the HAProxy stats socket is used to retrieve the metric but
13 if the optional URL option is set (see below), then the HAProxy URL is
14 used instead.
15
16 See the HAProxy documentation for detailed description of each metric.
17
19 pmdahaproxy reads an optional ini-style configuration file
20
21 · $PCP_PMDAS_DIR/haproxy/haproxy.conf
22
23 This file can contain in its [pmda] section overriding values for the
24 following PMDA options:
25
26 · user
27 · socket
28
29 By default, root and /var/lib/haproxy/stats, are used as values for
30 these options, respectively.
31
32 The section can also contain the following parameters:
33
34 · url
35 · auth
36 · pass
37
38 When the url option is defined, URL connection to HAProxy is used.
39 pmdahaproxy expects CSV data from the HAProxy URL; an example of a com‐
40 patible URL is http://127.0.0.1:9000/?stats;csv.
41
42 Note that the HAProxy statistics socket and/or URL need to be sepa‐
43 rately enabled in the HAProxy configuration file; please refer to the
44 HAProxy configuration documentation for details. Depending on system
45 and HAProxy configuration, using non-root user may also be possible,
46 especially with URL based connections.
47
48 Once the needed setup is ready, you can test the connection and install
49 the PMDA to enable access to the names and values for the HAProxy per‐
50 formance metrics. To install, do the following as root:
51
52 # cd $PCP_PMDAS_DIR/haproxy
53 # ./connect
54 # ./Install
55
56 To uninstall, do the following as root:
57
58 # cd $PCP_PMDAS_DIR/haproxy
59 # ./Remove
60
61 pmdahaproxy is launched by pmcd(1) and should never be executed
62 directly. The Install and Remove scripts notify pmcd(1) when the agent
63 is installed or removed.

82 Environment variables with the prefix PCP_ are used to parameterize the
83 file and directory names used by PCP. On each installation, the file
84 /etc/pcp.conf contains the local values for these variables. The
85 $PCP_CONF variable may be used to specify an alternative configuration
86 file, as described in pcp.conf(5).
