Add ARP collector for Linux (#540) * 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' 2017-04-11 08:45:19 -07:00			`IP address HW type Flags HW address Mask Device`

Add device filter flags to arp collector Allow filtering APR entries based on device. Useful for ignoring entries for network namespaces (containers). Signed-off-by: Ben Kochie <superq@gmail.com> 2021-12-16 05:13:20 -08:00			`10.0.0.1 0x1 0x2 de:ad:be:ef:00:00 * nope`
