Release v1.12.0

This release introduces a new feature for the crash probe. It will now collect source file and line number information for each frame in a backtrace if the data is available. Also, this release saw the beginning of migrating the code base to use libnica instead of glib, with the goal of reducing memory footprint of the telemetry daemon and probes. Future releases will convert more existing glib usage to libnica. Signed-off-by: Patrick McCarty <patrick.mccarty@intel.com>

+Telemetry service configuration file
+------------------------------------
+

+
+
+SYNOPSIS
+========
+
+``/etc/telemetrics/telemetrics.conf``
+
+``/usr/share/defaults/telemetrics/telemetrics.conf``
+
+
+DESCRIPTION
+===========
+
+This file contains configuration parameters for the ``telemd``\(1) telemetry
+service daemon. The daemon reads this file at startup if it exists.
+
+
+SYNTAX
+======
+
+The configuration file contains ``key=value`` pairs, formatted as plain
+text, one option per line. Comments can be added by preceding them with the
+``#`` character. All configuration options should be in a section marked
+with ``[settings]``.
+
+
+OPTIONS
+=======
+
+-  ``server=<url>``
+
+   Server URL including protocol designator.
+
+-  ``socket_path=<path>``
+
+   Path to the socket that `telemd` will listen on.
+
+-  ``cainfo=<path>``
+
+   Certificate file to use for validation of SSL endpoint.
+
+-  ``tidheader=<header>``
+
+   Telemetry ID in header format, usually ``tidheader=X-Telemetry-TID:<uuid>``
+   post header used to group records in ingestion service, which may be
+   ingesting for more than one set of clients. Can be set to any string.
+
+-  ``record_expiry=<minutes>``
+
+   Record expiry time in minutes.
+
+-  ``spool_dir=<dir>``
+
+   Local spool directory used to store records being processed.
+
+-  ``spool_max_size=<kB>``
+
+   maximum size of the spool directory in kB. A value of ``-1`` indicates
+   no limit. The block size of the files in this directory is considered,
+   and not the actual size of the record itself.
+
+-  ``spool_process_time=<seconds>``
+
+   Time in seconds for processing spool. Valid range: 120..3600. Values
+   outside this range are clamped.
+
+-  ``rate_limit_enabled=<true|false>``
+
+   Enable rate limiting. If this is set to false then all rate-limiting
+   disabled. It is possible to disable each rate-limit individually below.
+
+-  ``record_burst_limit=<limit>``
+
+   Rate limiting record burst limit. Valid Range:  0..``INT_MAX``, -1 = disabled.
+
+-  ``record_window_length=<minutes>``
+
+   Rate limiting record window length in minutes. Valid Range: 0..59.
+
+-  ``byte_burst_limit=<limit>``
+
+   Rate limiting byte burst limit. Valid Range:  0..`INT_MAX`, -1 = disabled.

Author	SHA1	Message	Date
Patrick McCarty	7d3a9d2834	Release v1.12.0 This release introduces a new feature for the crash probe. It will now collect source file and line number information for each frame in a backtrace if the data is available. Also, this release saw the beginning of migrating the code base to use libnica instead of glib, with the goal of reducing memory footprint of the telemetry daemon and probes. Future releases will convert more existing glib usage to libnica. Signed-off-by: Patrick McCarty <patrick.mccarty@intel.com>	2017-05-11 13:19:41 -07:00
Patrick McCarty	0af684e94e	Fix bug in is_banned_path(); group conditionals The checks in is_banned_path() for a path prefix not under /usr needed to be connected with a logical AND, not OR, as implied by the recent changes. Also, use an explicit logical OR for the other two groups of conditionals so that they are grouped similarly to the checks that required an AND.

Patrick McCarty	b7619e1a1c	Remove glib dependency for ASCII string check As far as I can tell, the standard library doesn't have a function to check for an ASCII string. Equivalently, we can iterate over each character in the string, byte by byte, and verify that only 7-bit characters are present.

Patrick McCarty	e699fd34e2	oops parser: support oops stack traces for Linux 4.10+ Linux 4.10 introduced some format changes for oopses; one of the changes was removing memory addresses from each stack frame.

Patrick McCarty	3d24527096	Release v1.11.0 This release reworks the journal probe to send records for log messages with higher log levels (LOG_EMERG, LOG_ALERT, LOG_CRIT, LOG_ERR), and also for messages that match EXIT_CODE="exited", which is set for systemd services that have exited with an error code. Also, a new opt-in feature has been added to disable certain privacy filters in the probes. With the filters disabled, the crash probe will collect backtraces for any crashing binary on the system, regardless of where the binary is installed. Also, the oops probe will collect real register values from kernel oopses instead of using "zero" or "non-zero". The opt in feature described above can be enabled by creating a file at: /etc/telemetrics/opt-in-no-privacy-filters Signed-off-by: Patrick McCarty <patrick.mccarty@intel.com>	2017-02-17 11:39:33 -08:00

Patrick McCarty	e375fe6825	journal probe: send records for every log message The previous logic concatenates log messages on initial startup, when the entire journal is read to process existing messages. But doing so might run into the payload size limit (8KB), and thus fail to create a record. Sending one record per log message will ensure that the payload size remains relatively small, almost always below the 8KB size limit.

Patrick McCarty	3aeb31ee3d	Add opt-in feature to disable privacy filters There are some filters in place that prevent probes from collecting specific types of data. In particular, the oops probe will report "zero" or "non-zero" for register values in oopses instead of the actual values. And the crash probe does not send backtraces if binaries live outside of /usr or under /usr/local. This commit keeps these filters in place but offers the capability to disable the filters by creating a file named /etc/telemetrics/opt-in-no-privacy-filters Any future telemetry privacy filters can check for this file to alter the reporting level.

Patrick McCarty	b671e770c9	Release v1.10.2 This release improves reliability of both the crash and oops probes. * The crash probe will now reprocess a core file if it encounters missing symbols when creating backtraces the first time. This improves telemetry when run on Clear Linux OS, which downloads debuginfo on-the-fly as needed. * The oops parsing will now capture "unreliable" stack frames for kernel oopses using the same notation as the kernel ("? "). Previously, the parsing code ignored the unreliable flag, so those frames appeared to be trustworthy frames. Signed-off-by: Patrick McCarty <patrick.mccarty@intel.com>	2017-02-06 14:50:43 -08:00
Patrick McCarty	2409452740	crash probe: retry processing when missing symbols Missing symbols in backtraces might indicate missing debuginfo from the crashed program, but another possibility is that on-the-fly debuginfo has not finished downloading. The Clear Linux OS uses an on-the-fly debuginfo setup, so this condition is likely for the first instance of a program crashing on the system. To decrease likelihood of missing symbols appearing, scan the backtrace for a frame with incomplete data after first processing, and if found, reprocess the core file after a 10 second pause.

Patrick McCarty	003928f52e	Preserve unreliable frames for kernel oopses When frame addresses detected during the stack scan were not previously found by unwinding, the string "? " is added as a prefix to the function name. However, the current oops parsing code strips "? " if encountered, so the backtraces from kernel oopses are missing vital information; the presence of "? " provides a hint for debugging a stack trace and indicates that the frame info is "unreliable". This commit removes the "? " strip code, ensuring the prefix is retained by the function name, and updates unit tests that check for oops lines that should contain the prefix.

Auke Kok	3e4360e2cb	Docs: Add manual pages using `ronn`. This adds several new manual pages to the project, ships them using `dist` and has a simple target to recreate the new roff files using the `ronn` utility: `make manpages`. These man pages are still very crude and contain the absolute minimum amount of information. I've attempted to cross link them as much as is reasonable. The telemetry API is documented in `telemetry(3)`. The important functions themselves are `linked` with a ref link that should make `man tm_create_record` (etc.) link to telemetry(3). I attempted to make this pass `make distcheck` and `make install` properly, but this should still be checked.	2016-12-08 17:47:25 -08:00
