- Move every collector into its own file
- Move FreeIPMI code into own package
- Allow more customization of commands executed by collectors
- Split up documentation, so README is a little less overwhelming
A single commit message does not do justice to the amount of changes
here, but hey... :)
There are systems that do not make this available, so don't make the
entire collector fail if only this metric can not be read. Instead, set
it to "N/A" if it cannot be determined.
This fixes#57.
It exposes two metrics about the IPMI system event log (SEL), the
current number of entries stored in it and the free space for new
records. The collector is not enabled by default, it has to be
explicitly enabled in the config.
Related to #41.
Specifically, allow definition of a set of settings as module in the
configuration file, and the ability to use these settings by setting the
`module` URL parameter to the respective module name when scraping.
THIS COMMIT CHANGES THE CONFIG FORMAT IN A NON-BACKWARDS-COMPATIBLE WAY!
Based on this, the following "side effects" are noteworthy:
- the exporter no longer requires a config file
- the IPMI "privilege level" can be set in the config file
- collectors can be enabled/disabled in the config file
- anonymous IPMI access is now theoretically possible
- there are now two example configurations (local & remote)
This fixes#10 by allowing to set the privilege level.
Unfortunately this is a breaking change, as this means going from
`-config.file` to `--config.file` syntax, but it needs to happen
eventually. It better aligns the IPMI exporter with the rest of the
Prometheus eco-system.
As a first benefit, expose the command line parameters that control the
logging library.
This enables the standard `/metrics` endpoint. A scrape will trigger the
collection of IPMI metrics from the local machine (that the exporter is
running on).
Instead of failing hard and not returning any metrics at all if just one
(or two) of the three calls to IPMI tools fail, return whatever data was
properly received and add a `collector` label to the `ipmi_up` metric
indicating which tools failed.
This is only a small step towards the concept of "collectors" like they
exist e.g. in the node exporter, but it should help solve #1. Additional
functionality, like disabling certain collectors, can be built on top of
this.
Currently, an error in the `ipmi` collector is always logged as an error,
In the `dcmi` and `bmc` collectors, an error retrieving the data is only
logged as debug output, but an error processing retrieved data is logged
as an error. This should cover most use cases and will be improved upon
once more work is done to make the collectors selectable per scrape.
