Alexei Gradinari	1b62781be0	res_fax: fix segfault on inactive "reserved" fax session The change #10017 "Handle fax gateway being started more than once" introdiced a bug which leads to segfault in res_fax_spandsp. The res_fax_spandsp module does not support reserving sessions, so fax_session_reserve returns a fax session with state AST_FAX_STATE_INACTIVE. The fax_gateway_start does not create a real fax session if the fax session is already present and the state is not AST_FAX_STATE_RESERVED. But the "reserved" session created for res_fax_spandsp has state AST_FAX_STATE_INACTIVE, so fax_gateway_start not starting. Then when fax_gateway_framehook is called and gateway T.38 state is NEGOTIATED the call of gateway->s->tech->write(gateway->s, f) leads to segfault, because session tech_pvt is not set, i.e. the tech session was not initialized/started. This patch adds check also on AST_FAX_STATE_INACTIVE to the "reserved" session created for res_fax_spandsp will start. This patch also adds extra check and log ERROR if tech_pvt is not set before call tech->write. ASTERISK-27981 #close Change-Id: Ife3e65e5f18c902db2ff0538fccf7d28f88fa803	7 years ago

Matt Jordan	0bb38796b7	res_prometheus: Add metrics for PJSIP outbound registrations When monitoring Asterisk instances, it's often useful to know when an outbound registration fails, as this often maps to the notion of a trunk and having a trunk fail is usually a "bad thing". As such, this patch adds monitoring metrics that track the state of PJSIP outbound registrations. It does this by looking for the Registry events coming across the Stasis system topic, and publishing those as metrics to Prometheus. Note that while this may support other outbound registration types (IAX2, SIP, etc.) those haven't been tested. Your mileage may vary. (And why are you still using IAX2 and SIP? It's 2019 folks. Get with the program.) This patch also adds Sorcery observers to handle modifications to the underlying PJSIP outbound registration objects. This is useful when a reload is triggered that modifies the properties of an outbound registration, or when ARI push configuration is used and an object is updated or deleted. Because we rely on properties of the registration object to define the metric (label key/value pairs), we delete the relevant metric when we notice that something has changed and wait for a new Stasis message to arrive to re-create the metric.

Matt Jordan	a2648b22eb	res_prometheus: Add CLI commands This patch adds a few CLI commands to the res_prometheus module to aid system administrators setting up and configuring the module. This includes: * prometheus show status: Display basic statistics about the Prometheus module, including its essential configuration, when it was last scraped, and how long the scrape took. The last two bits of information are useful when Prometheus isn't generating metrics appropriately, as it will at least tell you if Asterisk has had its HTTP route hit by the remote server. * prometheus show metrics: Dump the current metrics to the CLI. Useful for system administrators to see what metrics are currently available without having to cURL or go to Prometheus itself.

Friendly Automation	12cad5ec1a	Merge "Add core Prometheus support to Asterisk"	7 years ago
Matt Jordan	c50f29dfad	Add core Prometheus support to Asterisk Prometheus is the defacto monitoring tool for containerized applications. This patch adds native support to Asterisk for serving up Prometheus compatible metrics, such that a Prometheus server can scrape an Asterisk instance in the same fashion as it does other HTTP services. The core module in this patch provides an API that future work can build on top of. The API manages metrics in one of two ways: (1) Registered metrics. In this particular case, the API assumes that the metric (either allocated on the stack or on the heap) will have its value updated by the module registering it at will, and not just when Prometheus scrapes Asterisk. When a scrape does occur, the metrics are locked so that the current value can be retrieved. (2) Scrape callbacks. In this case, the API allows consumers to be called via a callback function when a Prometheus initiated scrape occurs. The consumers of the API are responsible for populating the response to Prometheus themselves, typically using stack allocated metrics that are then formatted properly into strings via this module's convenience functions. These two mechanisms balance the different ways in which information is generated within Asterisk: some information is generated in a fashion that makes it appropriate to update the relevant metrics immediately; some information is better to defer until a Prometheus server asks for it. Note that some care has been taken in how metrics are defined to minimize the impact on performance. Prometheus's metric definition and its support for nesting metrics based on labels - which are effectively key/value pairs - can make storage and managing of metrics somewhat tricky. While a naive approach, where we allow for any number of labels and perform a lot of heap allocations to manage the information, would absolutely have worked, this patch instead opts to try to place as much information in length limited arrays, stack allocations, and vectors to minimize the performance impacts of scrapes. The author of this patch has worked on enough systems that were driven to their knees by poor monitoring implementations to be a bit cautious. Additionally, this patch only adds support for gauges and counters. Additional work to add summaries, histograms, and other Prometheus metric types may add value in the future. This would be of particular interest if someone wanted to track SIP response types. Finally, this patch includes unit tests for the core APIs.

Joshua Colp	7a6fd83aca	res_rtp_asterisk: Fix sequence number cycling and packet loss count. This change fixes two bugs which both resulted in the packet loss count exceeding 65,000. The first issue is that the sequence number check to determine if cycling had occurred was using the wrong variable resulting in the check never seeing that cycling has occurred, throwing off the packet loss calculation. It now uses the correct variable. The second issue is that the packet loss calculation assumed that the received number of packets in an interval could never exceed the expected number. In practice this isn't true due to delayed or retransmitted packets. The expected will now be updated to the received number if the received exceeds it.

agupta	71040078a3	stasis: Only place stasis created and dialed channels into dial bridge. The dial bridge is meant to hold channels which have been created and dialed in stasis. It handles the frames coming from them and raises the appropriate events. It was possible for the code to mistakenly place calls which came from the dialplan into the dial bridge if they were not in an answered state. These channels are not outgoing channels and should not be placed into the dial bridge. The code now checks to ensure that only stasis created channels are placed into the dial bridge by checking that a PBX does not exist on the channel.

Joshua Colp	6bb70c93f1	rtp: Add support for transport-cc in receiver direction. The transport-cc draft is a mechanism by which additional information about packet reception can be provided to the sender of packets so they can do sender side bandwidth estimation. This is accomplished by having a transport specific sequence number and an RTCP feedback message. This change implements this in the receiver direction. For each received RTP packet where transport-cc is negotiated we store the time at which the RTP packet was received and its sequence number. At a 1 second interval we go through all packets in that period of time and use the stored time of each in comparison to its preceding packet to calculate its delta. This delta information is placed in the RTCP feedback message, along with indicators for any packets which were not received. The browser then uses this information to better estimate available bandwidth and adjust accordingly. This may result in it lowering the available send bandwidth or adjusting how "bursty" it can be.

Kevin Harwell	d1d0692858	bridge_softmix: use a float type to store the internal REMB bitrate REMB's exponent is 6-bits (0..63) and has a mantissa of 18-bits. We were using an unsigned integer to represent the bitrate. However, that type is not large enough to hold all potential bitrate values. If the bitrate is large enough bits were being shifted off the "front" of the mantissa, which caused the wrong value to be sent to the browser. This patch makes it so it now uses a float type to hold the bitrate. Using a float allows for all bitrate values to be correctly represented.

George Joseph	63d90c38eb	app.c: Remove deletion of pool topic on mwi state delete As part of an earlier voicemail refactor, ast_delete_mwi_state_full was modified to remove the pool topic for a mailbox when the state was deleted. This was an attempt to prevent stale topics from accumulating when app_voicemail was reloaded and a mailbox went away. Unfortunately because of the fact that when app_voicemail reloads, ALL mailboxes are deleted then only current ones recreated, topics were being removed from the pool that still had subscribers on them, then recreated as new topics of the same name. So now modules like res_pjsip_mwi are listening on a topic that will never receive any messages because app_voicemail is publishing on a different topic that happens to have the same name. The solutiuon to this is not easy and given that accumulating topics for deleted mailboxes is less evil that not sending NOTIFYs... * Removed the call to stasis_topic_pool_delete_topic in ast_delete_mwi_state_full.
