* Add gauges for allocated memory for queued UDP and TCP packages (#1503)Peter Bueschel2020-03-31
| | | | | | | | | | | | | | | | * Two new states will be added to the tcpstat collector called rx_queued_bytes and tx_queued_bytes. For UDP datagrams an additional collector 'udp_queues' can be used to expose the total lengths of the tx_queue and rx_queue. @SuperQ and @discordianfish this changes gives us the option to check for overloaded UDP + TCP processing. The names of the new TCP states and the UDP metric can be discussed. The current reasons are just: I don't want to add another collector for the same exposed file, so I just added the new states to the tcpstat collector. I chose the name 'udp_queue' instead of 'udpstat' as UDP has no state. Signed-off-by: Peter Bueschel <peter.bueschel@logmein.com>

* Fix num cpu (#1561)Daniel Hodges2020-02-20
| | | | | | | | | | | | | | | | | | | | * add a map of profilers to CPUids `runtime.NumCPU()` returns the number of CPUs that the process can run on. This number does not necessarily correlate to CPU ids if the affinity mask of the process is set. This change maintains the current behavior as default, but also allows the user to specify a range of CPUids to use instead. The CPU id is stored as the value of a map keyed on the profiler object's address.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This collector is based on adjtimex(2) system call. The collector returns three values, status if time is synchronised, offset to remote reference, and local clock frequency adjustment. Values are taken from kernel time keeping data structures to avoid getting involved how the synchronisation is implemented. By that I mean one should not care if time is update using ntpd, systemd.timesyncd, ptpd, and so on. Since all time sync implementation will always end up telling to kernel what is the status with time one can simply omit the software in between, and look results of the syncing. As a positive side effect this makes collector very quick and conceptually specific, this does not monitor availability of NTP server, or network in between, or dns resolution, and other unrelated but necessary things. Minimum set of values to keep eye on are the following three: The node_timex_sync_status tells if local clock is in sync with a remote clock. Value is set to zero when synchronisation to a reliable server is lost, or a time sync software is misconfigured. The node_timex_offset_seconds tells how much local clock is off when compared to reference. In case of multiple time references this value is outcome of RFC 5905 adjustment algorithm. Ideally offset should be close to zero, and it depends about use case how large value is acceptable. For example a typical web server is probably fine if offset is about 0.1 or less, but that would not be good enough for mobile phone base station operator. The node_timex_freq tells amount of adjustment to local clock tick frequency. For example if offset is one second and growing the local clock will need instruction to tick quicker. Number value itself is not very important, and occasional small adjustments are fine. When frequency is unusually in stable one can assume quality of time stamps will not be accurate to very far in sub second range. Obviously explaining why local clock frequency behaves like a passenger in roller coaster is different matter. Explanations can vary from system load, to environmental issues such as a machine being physically too hot. Rest of the measurements can help when debugging. If you run a clock server do probably want to collect and keep track of everything. Pull-request: https://github.com/prometheus/node_exporter/pull/664
* Add metrics from SNTPv4 packet to ntp collector & add ntpd sanity check (#655)Leonid Evdokimov2017-09-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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
