Asterisk and not only. Virtual file systems. Step back or two forward?

Describing participation in the project to upgrade VoIP carrier Part 1 and Part 2 , one of the tasks that fell out of sight was the creation of a unified tool for visualizing and monitoring the operation of the Asterisk server. In fact, after leaving this project, the obsession to bring the display of Asterisk information to a more convenient form resulted in a project to create a prototype of a unified virtual file system that combines the capabilities of all the disparate tools available in Asterisk.



I think that many of the administrators who dealt with Asterisk were often surprised at the number of different teams with which data could be obtained from Asterisk. The discussion will focus on user accounts for subscriber devices, users for authentication, channels, as well as non-standard use of virtual file systems.



Let us dwell on various methods of obtaining data.



The first is the most common.

Is not it familiar teams? And many use them almost daily. It's probably not a secret for anyone that Asterisk has a tree of objects. Access to it is provided through providers. The information in the tree is fuller than we have seen before.



 asterisk-macomnet*CLI> data show providers /asterisk/channel/iax2/peers (get) [chan_iax2.c] /asterisk/channel/iax2/users (get) [chan_iax2.c] /asterisk/channel/dahdi/version (get) [chan_dahdi.c] /asterisk/channel/dahdi/status (get) [chan_dahdi.c] /asterisk/channel/dahdi/channels (get) [chan_dahdi.c] /asterisk/channel/sip/peers (get) [chan_sip.c] /asterisk/core/hints (get) [pbx.c] /asterisk/core/channels (get) [channel.c] /asterisk/core/channeltypes (get) [channel.c] /asterisk/application/queue/list (get) [app_queue.c]


Access to the object tree allows you to have complete information about each of them.

Probably few people know, due to the lack of normal documentation for the "data get" command, but there is a search and grouping of fields in it.



Search by name or peer
 asterisk-macomnet*CLI> data get /asterisk/channel/sip/peers peers/peer/name=6001  asterisk-macomnet*CLI> data get /asterisk/channel/sip/peers peers/peer/secret=MegaPass12345 peers peer vmexten: "asterisk" is_realtime: False amaflags text: "Unknown" value: 0 transports: "UDP,WS" inuse: 0 timer_t1: 500 callingpres text: "Presentation Allowed, Not Screened" value: 0 unsolicited_mailbox: "" host_dynamic: True subscribecontext: "" useragent: "" rtptimeout: 0 cid_num: "6001" mohinterpret: "default" parkinglot: "" mwi_from: "" call_limit: 0 fullcontact: "" rtpholdtimeout: 0 qualifyfreq: 60000 maxms: 0 rtpkeepalive: 0 allowtransfer text: "open" value: 0 regexten: "" onhold: 0 ringing: 0 fromdomain: "" timer_b: 32000 fromuser: "" username: "" secret: "MegaPass12345" accountcode: "" t38_maxdatagram: -1 remotesecret: "" md5secret: "" maxcallbitrate: 384 mohsuggest: "" lastms: 0 sipoptions sec_agree: False histinfo: False join: False resource-priority: False precondition: False eventlist: False outbound: False recipient-list-invite: False early-session: False recipient-list-subscribe: False sdp-anat: False 100rel: False replaces: False from-change: False replace: False gruu: False tdialog: False privacy: False norefersub: False timer: False path: False pref: False tohost: "" autoframing: False name: "6001" cid_name: "6001" language: "ru" context: "web" description: "" type: "friend" engine: "asterisk" codecs codec frame_length: 33 samplespersecond: 8000 name: "gsm" description: "GSM" codec frame_length: 10 samplespersecond: 8000 name: "g729" description: "G.729A" codec frame_length: 80 samplespersecond: 8000 name: "ulaw" description: "G.711 u-law" codec frame_length: 80 samplespersecond: 8000 name: "alaw" description: "G.711 a-law"


Querying data from the tree supports filtering parameters. In this case, the search parameter must have the value "1 = 1"; any other search condition described above is ignored automatically.



 asterisk-macomnet*CLI> data get /asterisk/channel/sip/peers 1=1 peers/peer/cid_num,peers/peer/name,peers/peer/username,peers/peer/secret,peers/peer/lastms,peers/peer/fullcontact peers peer cid_num: "6001" fullcontact: "sip:6001@192.168.200.247:5060" username: "" secret: "MegaPass12345" lastms: 0 name: "6001" peer cid_num: "person" fullcontact: "" username: "person" secret: "E346fz8Vam" lastms: 0 name: "person"


Access to the tree is very convenient, but the default tree contains only entries that are hard-coded in the configuration files or entries of cached realtime connections. To get a full-fledged tree, you need to load all the parameters of all realtime connections from the database.



Displaying real-time peers is done with the command:



 asterisk-macomnet*CLI> sip show peer <name> load Usage: sip show peer <name> [load] Shows all details on one SIP peer and the current status. Option "load" forces lookup of peer in realtime storage.


Unfortunately, in order to download data, you need to know what to download.



 asterisk-macomnet*CLI> realtime load sippeers name zhecka Usage: realtime load <family> <colmatch> <value> Prints out a list of variables using the RealTime driver. You must supply a family name, a column to match on, and a value to match to.


As we see here, to download realtime connection data you also need to know what to load. But there is a dirty hack. The "colmatch" and "value" parameters are transferred to the sql provider "as is". Therefore, you can make a request of the form "realtime load sippeers 1 1" and get all the data in one request.



realtime load sippeers 1 1

This query will show all realtime peers that are available in the database.

Next, you need to execute the command by the name of each peer.



sip show peer zhecka load
 asterisk-macomnet*CLI> sip show peer zhecka load * Name : zhecka Description : Realtime peer: Yes, cached Secret : <Set> MD5Secret : <Not set> Remote Secret: <Not set> Context : web Record On feature : automon Record Off feature : automon Subscr.Cont. : <Not set> Language : ru Tonezone : <Not set> AMA flags : Unknown Transfer mode: open CallingPres : Presentation Allowed, Not Screened Callgroup : Pickupgroup : Named Callgr : Nam.

After these operations, the realtime entry "zhecka", currently in offline, appears in the internal data tree.



 asterisk-macomnet*CLI> data get /asterisk/channel/sip/peers 1=1 peers/peer/cid_num,peers/peer/name,peers/peer/username,peers/peer/secret,peers/peer/lastms,peers/peer/fullcontact peers peer cid_num: "" fullcontact: "" username: "zhecka" secret: "zhecka" lastms: 4294967295 name: "zhecka" peer cid_num: "6001" fullcontact: "" username: "" secret: "MegaPass12345" lastms: 0 name: "6001" peer cid_num: "person" fullcontact: "" username: "person" secret: "E346fz8Vam" lastms: 0 name: "person"


As can be seen from the presented sequence, in order to obtain data, it is necessary to perform several different operations for each base of the peer available in realtime.



Probably many of you will say: "There is REST! ​​Use it!"

I will answer: "Yes. REST is. But it is weak and does not give the necessary information"

Output REST request http: // localhost: 8088 / ari / endpoints / SIP



 [ { "technology": "SIP", "resource": "person", "state": "unknown", "channel_ids": [] }, { "technology": "SIP", "resource": "mtrf", "state": "unknown", "channel_ids": [] }, { "technology": "SIP", "resource": "6001", "state": "unknown", "channel_ids": [] } ]


Unfortunately, the required fields are missing in the output and you need to rewrite or add the REST module to add them.



So what is offered? And it is proposed to transfer the Asterisk tree to the file system in the manner of devfs / procfs and track all settings in one place.



It looks like this.



 # tree /mnt /mnt ├── config -> /usr/local/etc/asterisk ├── peers │  ├── iax2 │  │  ├── corbina │  │  │  └── full │  │  └── msm │  │  └── full │  └── sip │  ├── _offline │  │  └── mtrf -> ../mtrf │  ├── _online │  └── mtrf │  ├── codecs │  ├── contexts │  ├── credentials │  ├── full │  └── huntgroups └── users ├── iax2 │  └── macomnet │  └── full ├── sipfriends │  ├── 6001 │  │  ├── codecs │  │  ├── contexts │  │  ├── credentials │  │  ├── full │  │  └── huntgroups │  ├── _offline │  │  ├── 6001 -> ../6001 │  │  └── person -> ../person │  ├── _online │  │  └── zhecka -> ../zhecka │  ├── person │  │  ├── codecs │  │  ├── contexts │  │  ├── credentials │  │  ├── full │  │  └── huntgroups │  └── zhecka │  ├── codecs │  ├── contexts │  ├── credentials │  ├── full │  └── huntgroups └── sipusers ├── _offline │  └── zhecka1 -> ../zhecka1 ├── _online └── zhecka1 ├── codecs ├── contexts ├── credentials ├── full └── huntgroups


This is a real cast of the Asterisk test server file system. Since we are not limited in formatting the output data, the output of the parameters for the connection will look like this.



 # cat /mnt/users/sipfriends/_online/zhecka/credentials name=zhecka username=zhecka secret=zhecka md5secret= fromuser= fromdomain= cid_name= remotesecret= fullcontact=sip:zhecka@10.6.207.135:64802;transport=udp;rinstance=d42eec40501a7c4d useragent=Bria release 2.5 RC4 stamp 47242 regexten= transports=UDP,TCP


Or contexts



 # cat /mnt/users/sipfriends/_online/zhecka/contexts context=web subscribecontext=


All this data is obtained in real time, well, or with minimal delay in the processing of Asterisk Events, during the disconnection / connection of the device.



How it works? AstFS is written in Python and uses the Fuse library.



The Fuse library allows for each corresponding event (open, readdir, getattr, close, etc.) coming from the file system, to call the procedure that processes the incoming and generates the end user data.



Since the Fuse library, like most event-based libraries, has an internal loop, it is rather difficult to transfer data from an external program to it. You need a common object or pipe to work.



From the point of view of using a TCP / UDP socket pipe or something similar, in the event of a server or daemon failure providing data delivery, the request to the file system will hang uncontrollably. Again, because of its own internal loop, the library cannot be correctly implemented in asynchronous twisted frameworks (I did not succeed at least). Attempt to start everything through Threading caused a lot of different problems and had to abandon this idea. Calling the connection from the procedures directly to Asterisk caused the wildest overhead, since for each "sneeze" it was necessary to open a new connection to AMI.



The only more or less normal solution was the separation of the process serving requests to the file system and the process receiving data from Asterisk using multiprocessing . This component has the ability to control generated processes, as well as there are objects that can be "fumbled" between processes.



Thus, the system consists of three processes:





Between them, a common dictionary is "fumbled" packed in JSON. The fact is that common objects have a structure different from python structures and are not compatible with them. When updating data from Asterisk, this dictionary is unpacked, updated and packed back.



Accordingly, the process serving requests from the file system, if necessary, unpacks the dictionary and generates final data for the user.



The AstFS source code contains all the necessary classes and an example for creating a virtual file system. The code is certainly far from ideal, but will be modified for the better if possible (there are comments in Russian).



The focus was on the flexibility of the file system structure.



By flexibility is meant that either a class or a function or just static data can be used as a handler for a branch of a tree or file.



The definition of a tree is quite simple:



  root = { 'helpfilefunc': [fsstruct.stat_info['file'], fusefscore.returnhelp], 'link_to_tmp': [fsstruct.stat_info['link'], '/tmp'], 'staticfile': [fsstruct.stat_info['file'], 'contents of staticfile'], 'customchmodfile': [{'st_mode': 0x8000 | int('0600', 8), 'st_uid': 0, 'st_gid': 0}, 'contents of customchmodfile'], 'nulldir': {}, 'nullfile': [{}, ''], 'demotreeclass': fsstruct.BasicTree('/demotreeclass', mpd, ''), 'tree': {'peer': [{'st_mode': 0x8000 | int('0644', 8)}, 'contents of peer'], 'friend': {}, 'user': {}} } 


 # tree -ghpu /mnt/ /mnt/ ├── [-rw------- root wheel 27] customchmodfile ├── [drwxr-xr-x asterisk asterisk 512] demotreeclass │ ├── [-rw-r--r-- asterisk asterisk 12] help │ └── [-rw-r--r-- asterisk asterisk 12] info ├── [-rw-r--r-- asterisk asterisk 33] helpfilefunc ├── [lrwxr-xr-x asterisk asterisk 4] link_to_tmp -> /tmp ├── [drwxr-xr-x asterisk asterisk 512] nulldir ├── [-rw-r--r-- asterisk asterisk 0] nullfile ├── [-rw-r--r-- asterisk asterisk 22] staticfile └── [drwxr-xr-x asterisk asterisk 512] tree ├── [drwxr-xr-x asterisk asterisk 512] friend ├── [-rw-r--r-- asterisk asterisk 16] peer └── [drwxr-xr-x asterisk asterisk 512] user 6 directories, 7 files


If you need to define a file, then simply set the array (list) consisting of two parameters. The first is the type of file and access rights to it, the second is either the static content of the file, or the name of the function returning the contents of the file. If you need to define a directory, then simply define a dictionary (dict) containing in turn either a list of files or a list of directories. When determining the directory in which the dynamically changeable structure is located, you can specify a subclass that will handle all file system requests.



In fact, for a basic functional in a class, it suffices to describe 4 methods:





Let us dwell on the implementation features.



getattr is called to determine the type of file or directory, returns only attributes! No other information from this method is obtained.



readdir is called when opening a directory and requesting files, returns only a list of files located in a directory with no attributes!



With the usual call of the file list



 # ls /mnt customchmodfile demotreeclass helpfilefunc link_to_tmp nulldir nullfile staticfile tree


the following sequence occurs
