* 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>

* Add model_name and stepping to node_cpu_info metricBenjamin Drung2020-03-20
| | | | | | | | | The `node_cpu_info` metric contains some information like the `model` (which is an integer), but not the human readable model name. Also the stepping of the processor might be interesting, since different stepping of a processor might behave differently. Signed-off-by: Benjamin Drung <benjamin.drung@cloud.ionos.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.

* Don't count empty collection as success (#1613)Ben Kochie2020-02-19
| | | | | | | | | | | | | | Many collectors depend on underlying features to be enabled. This causes confusion about what "success" means. This changes the behavior of the `node_scrape_collector_success` metric. * When a collector is unable to find data don't return success. * Catch the no data error and send to Debug log level to avoid log spam. * Update collectors to support this new functionality. * Fix copy-pasta mistake in infiband debug message.
