This is 39th iteration of typo fixes
The naming issue on the argument called "unsued" instead of "unused"
in two functions from resolvers and stick-tables was put into a second
patch so that it can be omitted if it were to cause backport issues.
It is now possible to filter the metrics on their name, by listing
explicitly metrics to dump or on the opposite to exclude only some metrics
from the dump. To do so, a comma-separated list of metrics must be
specified. If a name is preceded by a minus (-), the metric is excluded from
the dump. If at least one metric is specified to be explicitly dumped, all
metrics are no longer dumped, but only those explicitly listed.
The list is specified via one or more "metrics" parameters in the uri
query-string. For insance:
# Dumped all metrics, except "haproxy_server_check_status"
/metrics?metrics=-haproxy_server_check_status
# Only dump frontends, backends and servers status
/metrics?metrics=haproxy_frontend_status,haproxy_backend_status,haproxy_server_status
Included and Excluded metrics can be mixed. Only the intersection will be
dumped.
This patch should fix the issue #770.
Just like for stick-tables, this patch adds a promex module to dump
resolvers metrics. It adds the "resolver" scope and for now, it dumps
folloowing metrics:
* haproxy_resolver_sent
* haproxy_resolver_send_error
* haproxy_resolver_valid
* haproxy_resolver_update
* haproxy_resolver_cname
* haproxy_resolver_cname_error
* haproxy_resolver_any_err
* haproxy_resolver_nx
* haproxy_resolver_timeout
* haproxy_resolver_refused
* haproxy_resolver_other
* haproxy_resolver_invalid
* haproxy_resolver_too_big
* haproxy_resolver_outdated
numbers of active and backup servers per backend were exported but the info
was not exported per-server. The main issue to do so was we were unable to
have a different name for the same metric in a different scope. Thanks to
the previous patch ("MINOR: promex: Add support for specialized
front/back/li/srv metric names") it is now possible. So the info is now
exported per-server.
This patch should fix the issue #2271.
"haproxy_backend_agg_server_status" and "haproxy_backend_agg_check_status"
were not referenced in promex README.
"haproxy_backend_agg_server_check_status" is also missing but it is a
deprecated metric. Thus, it is better to not reference it.
Let's start to better organize the addons by moving promex there (and
with an easier directory name). The makefile and maintainers files were
updated, as well as the CI's build matrix.
