Centos and oraclelinux repositories for prometheus include bespoke headers
in the environment files (e.g. Debian: ARGS=, Centos: PROMETHEUS_OPTS=
ALERTMANAGER_OPTS=). This has been added as a default pillar with osmap
variances.
Additionally archlinux repo install was failing so added basic support -
an issue still remains for the prometheus app itself due to the service
file included in the arch repo hardcoding some config options - resulting
in the possibility to duplicate arguments resulting in a service error.
The prometheus service currently does not start due to permissions not being
applied to a data folder. The added config.storage begins to solve this and
ensures alignment on all platforms but would result in a duplicate config
entry as above. Prometheus on arch therefore needs more work but the exporter
installs now work.
Resolves: #59
The --collector.systemd config argument is unavailable in the
older packages.
The formula handles either scenario so switching the check out from the
test pillar for --log.level=debug instead
Resolved issue identified in pull request check for debian
Added inspec checks for environment files and specifically prometheus
and node_exporter args. Provided comments throughout the key reference
points for users to signpost the differing approaches to args used along
with more clearly identifying the difference between archive and repo
approach. Tests appear to be working on both approaches though updates
have been focused at repo install method.
Fixes: #59
this commit makes `service name` to consider pillar provided values,
fallback to a consistent `service name` when {archive|package} is available
for the component, or to `service name == name` when no other value
is provided
