Fixes#30891
* Upgrade `graphite-web`, `carbon` and `whisper` from 1.0.2 -> 1.1.3.
* Replaced the deprecated `pythonPackages.graphite_influxdb` with
`pythonPackages.influxgraph.`
* Renamed `pythonPackages.graphite_web` to `pythonPackages.graphite-web`
to be consistent with the Python package name.
* Replaced the unmaintained `pythonPackages.graphite_pager` with
`pythonPackages.graphitepager`
* Moved all new packages from `python-packages.nix` to
`pkgs/development/python-modules`
The Datadog agent requires `gohai` to be available on its `$PATH` in
order to collect certain metrics.
It would previously start up and collect certain types of metrics, but
log errors related to the missing gohai binary.
This commit configures the systemd-unit to make gohai available at
runtime.
This fixes#39810.
- prometheus exporters are now configured with
`services.prometheus.exporters.<name>`
- the exporters are now defined by attribute sets
from which the options for each exporter are generated
- most of the exporter definitions are used unchanged,
except for some changes that should't have any impact
on the functionality.
Alertmanager 0.13.0 doesn't support single dash long options, so '-config.file'
for example is parsed as '-c', which leads to the service not starting.
apps.plugin requires capabilities for full process monitoring. with
1.9.0, netdata allows multiple directories to search for plugins and the
setuid directory can be specified here.
the module is backwards compatible with older configs. a test is
included that verifies data gathering for the elevated privileges. one
additional attribute is added to make configuration more generic than
including configuration in string form.
These packages will be placed into an environment using
`backendsToPackages`. This function explicitly maps backends to
`pkgs.nodePackages.${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.
