+Telemetrics-client
+==================
+
+This package provides the front end component of a complete telemetrics
+solution for Linux-based operating systems. Specifically, the front end
+component includes:
+
+- telemetrics probes that collect specific types of data from the operating
+  system. For more info on probes go [here](./src/probes).
+
+- a library, libtelemetry, that telemetrics probes use to create telemetrics
+  records and send them to the daemon for further processing.
+
+- telemprobd, a daemon that handles communication with probes and forwards records
+  to a second daemon.
+
+- telempostd, this daemon sends telemetry records to a telemetrics server
+  (not included in this source tree), or spools the records on disk in case
+  it's unable to successfully deliver them.
+
+A telemetrics server implementation that works with this component is available
+from
+[clearlinux/telemetrics-backend](https://github.com/clearlinux/telemetrics-backend).
+
+
+Build dependencies
+---------------------
+
+- libcheck
+
+- libcurl
+
+- elfutils, which provides libelf and libdwfl libraries..
+
+- (optional) libsystemd, for syslog-style logging to the systemd journal, and
+  socket/path activation of telemprobd and telempostd by systemd.
+
+
+Build and installation
+---------------------
+
+```{r, engine='bash', count_lines}
+$ ./autogen.sh
+$ ./configure
+$ make
+```
+
+Set up
+---------------------
+
+There is a config file installed at
+
+```{r, engine='bash', count_lines}
+/usr/share/defaults/telemetrics/telemetrics.conf
+```
+
+To make modifications, copy that file to
+
+```{r, engine='bash', count_lines}
+/etc/telemetrics/telemetrics.conf
+```
+and modify the /etc version.
+
+Descriptions of config options are listed below in the Usage section.
+
+Starting the client
+---------------------
+To use the telemetrics client a one time explicit ```opt-in``` is required (this is
+also true when the contents of the directory ```/etc/telemetrics/``` are removed).
+To opt-in to telemetrics-client use the command:
+
+```{r, engine='bash', count_lines}
+ telemctl opt-in
+```
+
+**Note** this is a change from previous versions, before 2.3.0 installation of
+telemetrics client was enough to enable the client and if needed the client could
+be disabled with ```telemctl opt-out```. This command in previous versions created
+```/etc/telemetrics/opt-out``` file (after telemetrics-client version 2.3.0 this
+file can be safely removed).
+
+If the client was compiled with systemd support the respective activation units
+should be already in place (after a ```make install``` invocation). In this case
+the client wil start automatically when data is made available to it. i.e. when
+executing an ```/usr/bin/hprobe``` command. Otherwise use the following command:
+
+```{r, engine='bash', count_lines}
+ telemctl start
+```
+Note: the above invocation technically readies the service for both socket and
+path activation, so you may not see an "active" status. To check the status of
+telemetrics-client use:
+
+```{r, engine='bash', count_lines}
+ telemctl is-active
+   telemprobd : active
+   telempostd : active
+```
+
+Starting individual service units ```telempostd.service``` or ```telemeprobd.service```
+is discouraged.
+
+Configure the client to autostart at boot
+---------------------
+
+As longs as the first time ```opt-in``` was performed, the following methods are valid:
+
+
+Method 1 (recommended):
+
+Enable the socket-activated service and path unit:
+
+```{r, engine='bash', count_lines}
+systemctl enable telemprobd.socket telempostd.path
+```
+
+Method 2:
+
+Enable services, which automatically enables the socket and path
+units as well:
+
+```{r, engine='bash', count_lines}
+systemctl enable telemprobd.service
+systemctl enable telempostd.service
+```
+
+Usage
+---------------------
+
+Once the client is running, the telemetrics probes will be ready to use.
+
+Available probes:
+
+* hprobe: A test program that utilizes libtelemetry to ensure
+that telemetrics-client works. It sends a "hello world" record to the server.
+
+* crash probe: A handler for core files that sends the corresponding backtraces
+to the server.
+
+The client uses the following configuration options from the configuration file:
+
+* server: This specifies the web server that the telempostd sends the telemetry records to
+* socket_path: This specifies the path of the unix domain socket that the
+  telemprobd listens on for connections from the probes
+* spool_dir: This config option is related to spooling. If the daemon is not
+  able to send the telemetry records to the backend server due to reasons such
+  as the network availability, then it stores the records in a spool directory.
+  This option specifies that path of the spool directory. This directory should
+  be owned by the same user that the daemon is running as.
+
+```{r, engine='bash', count_lines}
+    mkdir -p /var/spool/telemetry
+    chown -R telemetry:telemetry /var/spool/telemetry
+    systemctl restart telemprobd.service
+```
+
+* record_expiry: This is the time in minutes after which the records in the
+  spool directory are deleted by the daemon.
+* spool_max_size: This specifies the maximum size of the spool directory. When
+  the size of the spool directory reaches this limit, new telemetry records are
+  dropped by the daemon.
+* spool_process_time: This specifies the time interval in seconds that the
+  daemon waits for before checking the spool directory for records. The daemon
+  picks up the records in the order of modification date and tries to send the
+  record to the server. It sends a maximum of 10 records at a time. If it was
+  able to send a record successfully, it deletes the record from the spool.  If
+  the daemon finds a record older than the "record_expiry" time, then it
+  deletes that record. The daemon looks at a maximum of 20 records in a single
+  spool run loop.
+* rate_limit_enabled: This determines whether rate-limiting is enabled or
+  disabled. When enabled, there is a threshold on both records sent within a
+  window of time, and record bytes sent within a window a time.
+* record_burst_limit: This is the maximum amount of records allowed to be
+  passed by the daemon within the record_window_length of time. If set to -1,
+  the rate-limiting for record bursts is disabled.
+* record_window_length: This is the time, in minutes (0-59), that establishes
+  the window length for the record_burst_limit. EX: if record_burst_window=1000
+  and record_window_length=15, then no more than 1000 records can be passed
+  within any given fifteen minute window.
+* byte_burst_limit: This is the maximum amount of bytes that can be passed by
+  the daemon within the byte_window_length of time. If set to -1, the
+  rate-limiting for byte bursts is disabled.
+* byte_window_length: This is the time, in minutes (0-59), that establishes the
+  window length for the byte_burst_limit.
+* rate_limit_strategy: This is the strategy chosen once the rate-limiting
+  threshold has been reached. Currently the options are 'drop' or 'spool', with
+  spool being the default. If spool is chosen, records will be spooled and sent
+  at a later time.
+* record_retention_enabled: When this key is enabled (true) the daemon saves a
+  copy of the payload on disk from all valid records. To avoid the excessive use
+  of disk space only the latest 100 records are kept. The default value for this
+  configuration key is false.
+* record_server_delivery_enabled: This key controls the delivery of records to
+  ```server```, when enabled (default value) the record will be posted to the
+  address in the configuration file. If this configuration key is disabled (false)
+  records will not be spooled or posted to backend. This configuration key can
+  be used in combination with ```record_retention_enabled``` to keep copies of
+  telemetry records locally only.
+
+
+Data reported
+---------------------
+
+The data reported by the telemetry client could be understood as two main sets:
+metadata and a payload.
+
+The metadata is used to report details of a machine's architecture. The
+following are the metadata values currently collected (Record Format Version 4):
+
+* record_format_version: version of the record, currently is 'Version 4'. This
+  value changes when new metadata is added.
+* classification: this field is used to identify the type of record sent by a
+  specific client probe; classifications use the format DOMAIN/PROBE/REST, where
+  DOMAIN is the vendor of the probe, PROBE is the probe name, and REST is a
+  probe-defined field to classify what is contained in the payload.
+* severity: this is an integer value between 1 and 4 where 1 is "low" and 4 is
+  "critical"
+* machine_id: a machine identifier that is rotate every 3 days for privacy reasons.
+* creation_timestamp: timestamp when the record was collected.
+* arch: a string describing machine architecture i.e. 'x86_64'.
+* host_type: a string with the combination of 'System Vendor', 'Product Name', and
+  'Product Version' read from dmi file system.
+* build: OS build number.
+* kernel_version: Kernel version.
+* payload_format_version: version of the payload, currently is 'Version 1'.
+* system_name: the value after 'ID=' from '/etc/os-release' (or distribution
+  provided folder)
+* board_name: a string read from dmi file system that combines 'Board Name' and
+  'Board Vendor'.
+* cpu_model: cpu model name extracted from '/proc/cpuinfo'.
+* bios_version: BIOS version.
+* event_id: an id to group multiple records if these were generated by a single
+  event occurrence.
+
+The payload as mentioned above is reported by probes. The telemetry library adds
+the metadata to the payload (done programatically when using library API) for
+more information about probes go [here](./src/probes).
+
+
+Machine id
+---------------------
+
+The machine id reported by the telemetry client is rotated every 3 days for
+privacy reasons. If you wish to have a static machine id for testing purposes,
+you can opt in by creating a static machine id file named
+"opt-in-static-machine-id" under the directory  "/etc/telemetrics/". Where
+"unique machine ID" is your desired static machine ID:
+
+```{r, engine='bash', count_lines}
+# mkdir -p /etc/telemetrics
+# echo "unique machine ID" > /etc/telemetrics/opt-in-static-machine-id
+```
+
+The telemetry client reads, at most, the first 32 characters from this file
+uses it for the machine id. You can put a string like 'my-machine-name' in this
+file to easily identify your machine.  Restart telemprobd for the machine id
+changes to take effect by running:
+
+```{r, engine='bash', count_lines}
+# systemctl restart telemprobd.service
+```
+
+You can switch back to the rotating machine id by deleting the override file
+and restarting the client.  You can do a quick test to check that your
+machine-id has changed by running "hprobe" and verifying that a record has
+landed on your backend telemetrics server, with the specified machine id.
+
+Event Id
+----------------------
+
+This is a 32 character lowercase hexadecimal string i.e. '5de9de8d5f3c6a7d445d75ba01cc3322'.
+This header is used to group multiple records by an event id. Before this header
+every single record could have been thought of an event, however this is not always
+the case. There are "events" that trigger the creation of multiple records (i.e.
+updates). The ```event_id``` header was added for probes with the capability to
+detect events and group records based on such events. This header was added to
+```telem-record-gen``` and can be specified using the ```-e``` (```--event-id```
+long form) switch.
+
+```{r, engine=bash, count_lines}
+  -e, --event-id        Event id to use in the record
+```
+
+Debugging locally with telemetrics-client
+-----------------------------------------------
+
+The function of the telemetrics-client is to handle the transport of information
+reported by a probe to a backend (see ```server``` key in configuration). This
+information is helpful for developers to debug and fix reported crashes, however
+developers not always have access to the backend in these case users can leverage
+features added for local debugging. The following is a list of steps to enable
+local debug:
+
+* *Enabling record retention*: this step configures telempostd to keep
+copies of telemetry records locally. To enable record retention set the value of
+```record_retention_enabled``` from ```false``` to ```true```. Optionally set
+```record_server_delivery_enabled`` to ```false``` to keep records local only.
+Remember to restart the client after configuration values are updated
+(```telemctl restart```).
+
+* *Creating a record*: run ```hprobe``` command to create a record for the purposes
+of this step by step guide. Once we have the record or records that you need to
+capture locally you can display the data.
+
+* *Displaying record metadata*: telempostd keeps metadata of any valid record,
+to display this data a new option to telemctl was added ```telemctl journal```.
+Assuming that the last record created was the record from previous step `hprobe` we
+can use `tail -n 1` to print the last created record only, i.e.
+
+```
+$ sudo telemctl journal | tail -n 1
+$ org.clearlinux/hello/world     Mon 2018-04-02 17:48:01 UTC a19a0d41ba16788881e274b19b8a1be4 5de9de8d5f3c6a7d445d75ba01cc3322 60c014cd-4693-40f1-b334-548cd932949b
+```
+
+The headers for the metadata (along with other information) can be printed using the
+```-V``` switch with ```telemctl journal``` command, i.e.
+
+```
+$ sudo telemctl journal -V | head -n 1
+$ Classification             Time stamp              Record ID                    Event ID                     Boot ID
+```
+
+* *Displaying record payload*: to print the content of a record payload you can use
+the ```-i``` (```--include_record``` long format) option to ```telemctl journal```
+command. To print the specific record you created you can use the option ```-r```
+(```--record_id``` long format) with the Record Id of the generated record, i.e.
+
+```
+$ sudo telemctl journal --record_id a19a0d41ba16788881e274b19b8a1be4 --include_record
+$ org.clearlinux/hello/world     Mon 2018-04-02 17:48:01 UTC a19a0d41ba16788881e274b19b8a1be4 5de9de8d5f3c6a7d445d75ba01cc3322 60c014cd-4693-40f1-b334-548cd932949b

+/**
+ * The Nica INI Parser focuses on simplicity and ease of use, therefore it
+ * currently only supports a read-only parse operation.
+ *
+ * The parse functions are used to return a _root_ @NcHashmap which contains
+ * name to section mappings. Each section is in turn an @NcHashmap with string
+ * to string mappings.
+ *
+ * Consider the following example:
+ *
+ *      [Person]
+ *      alive = true
+ *      ; This person is alive
+ *
+ * The returned @NcHashmap will contain the key "Person", which corresponds to
+ * another @NcHashmap. This @NcHashmap will contain the key "alive", which has
+ * the value "true". Therefore we can access this variable using the @NcHashmap
+ * API:
+ *
+ *      char *alive = nc_hashmap_get(nc_hashmap_get(ini, "Person"), "alive");
+ *
+ * Conversely, we can use the API to determine whether a section or key is set:
+ *
+ *      if (nc_hashmap_contains(ini, "Person"))
+ *
+ * As @NcHashmap returns NULL in nc_hashmap_get, you can happily pass NULL
+ * keys, allowing quick key fetches without checking if the section exists.
+ *
+ * In our INI file, lines beginning with ";" or "#" are considered as comments
+ * and are not processed. A line following the "key = value" notation is an
+ * _assignment_. "[Section]" is considered to be a section in the INI file, and
+ * all INI files must have at least one section.
+ *
+ * We do allow duplication section definitions, by following a merge policy. If
+ * a key is redefined then the original key->value mapping is freed and the new
+ * key->value mapping is inserted.
+ *
+ * The parser will return a correctly configured @NcHashmap, the only cleanup
+ * required is to call nc_hashmap_free on it. Alternatively, use the autofree
+ * helper, for a RAII approach:
+ *
+ *      autofree(NcHashmap) *map = nc_ini_file_parse("myfile.ini");

+# Probes
+
+The default probes provided along the telemetry client code are:
+
+* crashprobe: This probe processes core dump files. It can be registered as
+  the kernel core file handler in /proc/sys/kernel/core_pattern.
+
+* hprobe: a simple probe that sends a keep alive message. This probe can also
+  be useful for testing
+
+* journalprobe: a probe that monitors the systemd journal for log messages
+  from failed services.
+
+* klogscanner: a probe to collect 'oops messages' when the kernel detects a
+  problem. Also reports errors in the Boot Error Region Table if detected.
+
+* pstoreprobe: probe to collect messages left on pstore filesystem.
+
+* telem-record-gen: this is a "general-purpose probe" for sending custom
+  records on-the-fly. This tool can be used stand alone or as a part of a
+  script to implement a probe.
+
+For example to generate an hprobe like message we can execute the following
+command:
+
+```
+$ telem-record-gen --class org.example/hello/world --payload hello
+```
+
+for more options use the ```--help``` switch i.e.:
+
+```
+$ telem-record-gen --help
+Usage:
+  telem-record-gen [OPTIONS] - create and send a custom telemetry record
+
+Help Options:
+  -h, --help            Show help options
+
+Application Options:
+  -f, --config-file     Path to configuration file (not implemented yet)
+  -V, --version         Print the program version
+  -s, --severity        Severity level (1-4) - (default 1)
+  -c, --class           Classification level_1/level_2/level_3
+  -p, --payload         Record body (max size = 8k)
+  -P, --payload-file    File to read payload from
+  -R, --record-version  Version number for format of payload (default 1)
+  -e, --event-id        Event id to use in the record
+
+```
