These packages will be placed into an environment using
`backendsToPackages`. This function explicitly maps backends to
`pkgs.nodePackages.${type}` unless it's a builtin. This ensures that only
valid backends that work on NixOS are used (if not, the build already
breaks at evaluation time).
The log will be redirected to `stdout` to be able to watch the entire
output using `journalctl`.
Configuration parameters for the backends need to be set using
`services.statsd.extraConfig` as each backend has its own options and
all of them shouldn't be validated and checked explicitly and manually.
The munin-node service used wrapProgram to inject environment variables.
This doesn't work because munin plugins depend on argv[0], which is
overwritten when the executable is a script with a shebang line (example
below).
This commit removes the wrappers and instead passes the required
environment variables to munin-node.
Eliminating the wrappers resulted in some broken plugins, e.g., meminfo
and hddtemp_smartctl. That was fixed with the per-plugin configuration.
Example:
The plugin if_eth0 is a symlink to /.../plugins/if_, which uses $0
to determine that it should monitor traffic on the eth0 interface.
if_ is a wrapped program, and runs `exec -a "$0" .if_-wrapped`
.if_-wrapped has a "#!/nix/.../bash" line, which results in bash
changing $0, and as a result the plugin thinks my interface
is called "-wrapped".
The behaviour have changed again. Listed collectors are now enabled in
addition to the default one.
Also run as DynmicUser instead of user nobody as the exporter doesn't need
any state.
* prometheus-collectd-exporter service: init module
Supports JSON and binary (optional) protocol
of collectd.
* nixos/prometheus-collectd-exporter: submodule is not needed for collectdBinary
"Builder called die: Cannot wrap
/nix/store/XXX-munin-available-plugins/plugin.sh because it is not an
executable file"
[Bjørn: Keep DRY, quote "$file".]
* removed pid-file support, it is needless to run collectd as systemd service
* removed static user id, as all the files reowned on the service start
* added ambient capabilities for ping and smart (hdd health) functions
While systemd suggests using the pre-defined graphical-session user
target, I found that this interface is difficult to use. Additionally,
no other major distribution, even in their unstable versions, currently
use this mechanism.
The window or desktop manager is supposed to run in a systemd user service
which activates graphical-session.target and the user services that are
binding to this target. The issue is that we can't elegantly pass the
xsession environment to the window manager session, in particular
whereas the PassEnvironment option does work for DISPLAY, it for some
mysterious reason won't for PATH.
This commit implements a new graphical user target that works just like
default.target. Services which should be run in a graphical session just
need to declare wantedBy graphical.target. The graphical target will be
activated in the xsession before executing the window or display manager.
Fixes#17858.
to /etc/dd-agent/conf.d by default, and make sure
/etc/dd-agent/conf.d is used.
Before NixOS 17.03, we were using dd-agent 5.5.X which
used configuration from /etc/dd-agent/conf.d
In NixOS 17.03 the default conf.d location is first used relative,
meaning that $out/agent/conf.d was used without NixOS overrides.
This change implements similar functionality as PR #25288, without
breaking backwards compatibility.
