Use the offset calculation that includes round trip time in the ntp collector Previously the raw time difference was used which includes the network trip time between the node and the ntp server. This makes setting alerts off the value troublesome as it depends on the latency as well as the clock offset. 2016-06-01 00:56:20 -07:00			`Brett Vickers (beevik)`

Add metrics from SNTPv4 packet to ntp collector & add ntpd sanity check (#655) * Add metrics from SNTPv4 packet to ntp collector & add ntpd sanity check 1. Checking local clock against remote NTP daemon is bad idea, local ntpd acting as a client should do it better and avoid excessive load on remote NTP server so the collector is refactored to query local NTP server. 2. Checking local clock against remote one does not check local ntpd itself. Local ntpd may be down or out of sync due to network issues, but clock will be OK. 3. Checking NTP server using sanity of it's response is tricky and depends on ntpd implementation, that's why common `node_ntp_sanity` variable is exported. * `govendor add golang.org/x/net/ipv4`, it is dependency of github.com/beevik/ntp * Update github.com/beevik/ntp to include boring SNTP fix * Use variable name from RFC5905 * ntp: move code to make export of raw metrics more explicit * Move NTP math to `github.com/beevik/ntp` * Make `golint` happy * Add some brief docs explaining `ntp` #655 and `timex` #664 modules * ntp: drop XXX comment that got its decision * ntp: add `_seconds` suffix to relevant metrics * Better `node_ntp_leap` comment * s/node_ntp_reftime/node_ntp_reference_timestamp_seconds/ as requested by @discordianfish * Extract subsystem name to const as suggested by @SuperQ 2017-09-19 01:36:14 -07:00			`Meng Zhuo (mengzhuo)`
