* 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>

* Expose /proc/pressure (#1261)Daniele Sluijters2019-04-18
| | | | | | | | | This enables the collection of pressure stall information as exposed by the `/proc/pressure` interface added in the 4.20 release of the Linux kernel. Closes #1174 Signed-off-by: Daniele Sluijters <daenney@users.noreply.github.com>
* collector/cpu: split cpu freq metrics into separate collector (#1253)Paul Gier2019-02-19
| | | | | | | | | | | The cpu frequency information is not always needed and/or available. This change allows the cpu frequency metrics to be enabled/disabled separately from the other cpu metrics, and also prevents a frequency metric failure (such as a parse error) from failing the main cpu collector. Fixes #1241 Signed-off-by: Paul Gier <pgier@redhat.com>

* Add bcache collector (#597)ideaship2017-07-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Add bcache collector for Linux This collector gathers metrics related to the Linux block cache (bcache) from sysfs. * Removed commented out code * Use project comment style * Add _sectors to metric name to indicate unit * Really use project comment style * Rename bcache.go to bcache_linux.go * Keep collector namespace clean Rename: - metric -> bcacheMetric - periodStatsToMetrics -> bcachePeriodStatsToMetric * Shorten slice initialization * Change label names to backing_device, cache_device * Remove five minute metrics (keep only total) * Include units in additional metric names * Enable bcache collector by default * Provide metrics in seconds, not nanoseconds * remove metrics with label "all" * Add fixtures, update end-to-end for bcache collector * Move fixtures/sys into tar.gz This changeset moves the collector/fixtures/sys directory into collector/fixtures/sys.tar.gz and tweaks the Makefile to unpack the tarball before tests are run. The reason for this change is that Windows does not allow colons in a path (colons are present in some of the bcache fixture files), nor can it (out of the box) deal with pathnames longer than 260 characters (which we would be increasingly likely to hit if we tried to replace colons with longer codes that are guaranteed not the turn up in regular file names). * Add ttar: plain text archive, replacement for tar This changeset adds ttar, a plain text replacement for tar, and uses it for the sysfs fixture archive. The syntax is loosely based on tar(1). Using a plain text archive makes it possible to review changes without downloading and extracting the archive. Also, when working on the repo, git diff and git log become useful again, allowing a committer to verify and track changes over time. The code is written in bash, because bash is available out of the box on all major flavors of Linux and on macOS. The feature set used is restricted to bash version 3.2 because that is what Apple is still shipping. The programm also works on Windows if bash is installed. Obviously, it does not solve the Windows limitations (path length limited to 260 characters, no symbolic links) that prompted the move to an archive format in the first place.

* Add a collector for NFS client statistics.Ed Schouten2016-12-09
| | | | | | | | | | | | | This change adds a new collector called "nfs" that parses the contents of /proc/net/rpc/nfs and turns it into metrics. It can be used to inspect the number of operations per type, but also to keep an eye on an extraneous number of retransmissions, which may indicate connectivity issues. I've picked the name "nfs", as most operating systems use "nfs" for the client component and "nfsd" as the server component. If we want to add stats for the NFS server as well, we'd better call such a collector "nfsd".
