Since Go 1.8 32bit MIPS Big/Little Endian are supported assuming the
target runs Linux and the kernel either emulates an FPU or can access
the CPU one.
This allows the node_collector to build for mips and mipsle opening up
the possibility of running it on things like home routers
(DD-|Open|ASUS-)Wrt firmware usually has the necessary bits in place.
* Implement commonalities and linux support for ARP collection
* Add ARP collector to fixtures and run as part of e2e tests
* Bubble up scanner errors
* Use single return values where it makes sense
* Add missing annotation
* Move arp_common into arp_linux
* Add license header to arp_linux.go
* Address initial feedback
* Use strings.Fields instead of strings.Split
* Deal with scanner.Err() rather than throwing away errors
* Check for scan errors in-line before interacting with the entries map
* Don't interact with potentially empty text from scan
* Check for scan errors outside the scan loop
* Add comment about moving procfs parsing
* Add more direct comment
* Update initialism style to match go style guide
* Put function args on the same line
* Add TODO in front of comment about procfs extraction
* Guard against strings.Fields returning an empty slice
* Be more defensive about ARP table format and use upcase more broadly
* Enable the ARP collector by default
* Add ARP collector to the README
* Remove 'entry'
There are crossbuild errors on netbsd/arm with go1.8. Assuming there is
only a small minority of people running netbsd on ARM processors,
disabling these builds is the fastest workaround.
If this is not desired, copy/symlink these binaries to a different path and
set the respective environment variables. For example:
ln -s "$(GOPATH)/bin/{promu,staticcheck}" /usr/local/bin/
PROMU=/usr/local/bin/promu STATICCHECK=/usr/local/bin/staticcheck make
Instead of maintaining a counter metric for device errors in memory,
this change exports a gauge and uses const metrics to avoid leaking
metrics for unmounted filesystems.
"%d" in awk will truncate values at 2^31. S.M.A.R.T. values can exceed that, thus use a floating point notation instead to encode larger values (at the possible cost of some precision).
Older versions of the OFED drivers contain 64-bit variants of the port counters and are located in a directory named 'counters_ext'. This patch includes these older metrics that have since been deprecated with OFED 4.0.
