Bas van Dijk 285fd3c05a nixos/prometheus: abstract over optional option creation 2019-04-18 11:55:43 +02:00
Bas van Dijk 55ef5d4246 nixos/prometheus: set optional attributes to type types.nullOr
This makes sure that when a user hasn't set a Prometheus option it
won't show up in the prometheus.yml configuration file. This results
in smaller and easier to understand configuration files.

Bas van Dijk 57e5b75f9c nixos/prometheus: filter out the _module attr in a central place
We previously filtered out the `_module` attribute in a NixOS
configuration by filtering it using the option's `apply` function.

This meant that every option that had a submodule type needed to have
this apply function. Adding this function is easy to forget thus this
mechanism is error prone.

We now recursively filter out the `_module` attributes at the place we
construct the Prometheus configuration file. Since we now do the filtering
centrally we don't have to do it per option making it less prone to errors.

Bas van Dijk a913d0891c nixos/prometheus: filter out empty srcape_configs attributes
This results in a smaller prometheus.yml config file.

It also allows us to use the same options for both prometheus-1 and
prometheus-2 since the new options for prometheus-2 default to null
and will be filtered out if they are not set.

Bas van Dijk c95179b52f nixos/prometheus: add back the option services.prometheus.dataDir
This is to ensure more backwards compatibility. Note this is not 100%
backwards compatible because we now require dataDir to begin with /var/lib/.

nixos/prometheus: get rid of empty arguments
Previously the prometheus.service file looked like:

  ExecStart=/nix/store/wjkhfw3xgkmavz1akkqir99w4lbqhak7-prometheus-1.8.2-bin/bin/prometheus -storage.local.path=/var/lib/prometheus/metrics \
    -config.file=/nix/store/zsnvzw51mk3n1cxjd0351bj39k1j6j27-prometheus.yml-check-config-checked \
    -web.listen-address=0.0.0.0:9090 \
    -alertmanager.notification-queue-capacity=10000 \
    -alertmanager.timeout=10s \
     \

  Restart=always

Now it's:

  ExecStart=/nix/store/wjkhfw3xgkmavz1akkqir99w4lbqhak7-prometheus-1.8.2-bin/bin/prometheus \
    -storage.local.path=/var/lib/prometheus/metrics \
    -config.file=/nix/store/zsnvzw51mk3n1cxjd0351bj39k1j6j27-prometheus.yml-check-config-checked \
    -web.listen-address=0.0.0.0:9090 \
    -alertmanager.notification-queue-capacity=10000 \
    -alertmanager.timeout=10s
  Restart=always

nixos/prometheus: use ExecStart instead of a shell script
This uses fewer lines of code and one less process.

Add prometheus2 configuration to the prometheus modules
As the configuration for the exporters and alertmanager is unchanged
between the two major versions this patch tries to minimize
duplication while at the same time as there's no upgrade path from 1.x
to 2.x, it allows running the two services in parallel. See also #56037

nixos/prometheus: make source_labels optional
It's possible to skip `source_labels` entirely, an example for this is
the blackbox exporter configuration:

Andreas Rammhold 6795bdd58c nixos/prometheus: check configuration before starting service
With `promtool` we can check the validity of a configuration before
deploying it. This avoids situations where you would end up with a
broken monitoring system without noticing it - since the monitoring
broke down. :-)

Andreas Rammhold 0de150e0f2 nixos/prometheus: add package option
With a package option we can let the user decide what package to use for
prometheus without requiring an overlay.

Tanner Doshier b846ce5243 prometheus service: fix basic auth option
If some configuration is provided, we need to filter out the `_module` key or
else it breaks prometheus.

Bjørn Forsman b20fdff521 nixos/prometheus: make scrapeConfigs.*.static_configs.*.labels optional
...by providing a default value of "no labels" (an empty attrset).

Without this change we get

  $ nixos-rebuild test -I nixpkgs=.
  building Nix...
  building the system configuration...
  error: The option `services.prometheus.scrapeConfigs.[definition 1-entry 1].static_configs.[definition 1-entry 1].labels' is used but not defined.

which is unneeded, because labels _are_ optional.

Bjørn Forsman caa476b357 nixos/prometheus: add services.prometheus.configText option
The structured options are incomplete compared to upstream and I think
it will be a maintenance burden to try to keep up. Instead, provide an
option for the raw config file contents (prometheus.yml).
