NAME

6       cupsd-logs - cupsd log files (access_log, error_log, and page_log)
7

DESCRIPTION

9       cupsd(8)  normally  maintains  three  log  files:  access_log  to track
10       requests that are  submitted  to  the  scheduler,  error_log  to  track
11       progress  and  errors,  and  page_log  to track pages that are printed.
12       Configuration directives in cupsd.conf(5) and  cups-files.conf(5)  con‐
13       trol what information is logged and where it is stored.
14
15   ACCESS LOG FILE FORMAT
16       The  access_log file lists each HTTP resource that is accessed by a web
17       browser or client.  Each line is in an  extended  version  of  the  so-
18       called  "Common  Log Format" used by many web servers and web reporting
19       tools:
20
21           host group user date-time "method resource version" status bytes
22             ipp-operation ipp-status
23
24       For example:
25
26           10.0.1.2 - - [01/Dec/2005:21:50:28 +0000] "POST / HTTP/1.1" 200 317
27             CUPS-Get-Printers successful-ok-ignored-or-substituted-attributes
28           localhost - - [01/Dec/2005:21:50:32 +0000] "GET /admin HTTP/1.1"
29             200 0 - -
30           localhost - - [01/Dec/2005:21:50:32 +0000] "POST / HTTP/1.1"
31             200 157 CUPS-Get-Printers
32             successful-ok-ignored-or-substituted-attributes
33           localhost - - [01/Dec/2005:21:50:32 +0000] "POST / HTTP/1.1"
34             200 1411 CUPS-Get-Devices -
35           localhost - - [01/Dec/2005:21:50:32 +0000] "GET /admin HTTP/1.1"
36             200 6667 - -
37
38       The host field will normally only be an  IP  address  unless  you  have
39       enabled  the HostNameLookups directive in the cupsd.conf file or if the
40       IP address corresponds to your local machine.
41
42       The group field always contains "-".
43
44       The user field is the authenticated username of  the  requesting  user.
45       If no username and password is supplied for the request then this field
46       contains "-".
47
48       The date-time field is the date and time of the request in  local  time
49       and is in the format "[DD/MON/YYYY:HH:MM:SS +ZZZZ]".
50
51       The  method  field  is  the HTTP method used: "GET", "HEAD", "OPTIONS",
52       "POST", or "PUT".  "GET" requests  are  used  to  get  files  from  the
53       server,  both  for  the  web interface and to get configuration and log
54       files.  "HEAD" requests are used to get information  about  a  resource
55       prior  to  a "GET".  "OPTIONS" requests are used to upgrade connections
56       to TLS encryption.  "POST" requests are used for  web  interface  forms
57       and  IPP  requests.   "PUT"  requests  are used to upload configuration
58       files.
59
60       The resource field is the filename of the requested resource.
61
62       The version field is the HTTP specification version used by the client.
63       For CUPS clients this will always be "HTTP/1.1".
64
65       The  status  field  contains  the HTTP result status of the request, as
66       follows:
67
68            200  Successful operation.
69
70            201  File created/modified successfully.
71
72            304  The requested file has not changed.
73
74            400  Bad HTTP request; typically this means that you have a  mali‐
75                 cious program trying to access your server.
76
77            401  Unauthorized,   authentication   (username   +  password)  is
78                 required.
79
80            403  Access is forbidden; typically this means that a client tried
81                 to  access  a file or resource they do not have permission to
82                 access.
83
84            404  The file or resource does not exist.
85
86            405  URL access method is not allowed; typically  this  means  you
87                 have a web browser using your server as a proxy.
88
89            413  Request  too  large; typically this means that a client tried
90                 to print a file larger than the MaxRequestSize allows.
91
92            426  Upgrading to TLS-encrypted connection.
93
94            500  Server error; typically  this  happens  when  the  server  is
95                 unable to open/create a file - consult the error_log file for
96                 details.
97
98            501  The client requested encryption but encryption support is not
99                 enabled/compiled in.
100
101            505  HTTP  version number not supported; typically this means that
102                 you have a malicious program trying to access your server.
103
104       The bytes field contains the number of bytes in the request.  For  POST
105       requests  the  bytes field contains the number of bytes of non-IPP data
106       that is received from the client.
107
108       The ipp-operation field contains either "-" for non-IPP requests or the
109       IPP operation name for POST requests containing an IPP request.
110
111       The  ipp-status  field  contains either "-" for non-IPP requests or the
112       IPP status code name for POST requests containing an IPP response.
113
114   ERROR LOG FILE FORMAT
115       The error_log file lists messages from the scheduler  -  errors,  warn‐
116       ings,  etc.  The  LogLevel directive in the cupsd.conf(5) file controls
117       which messages are logged:
118
119           level date-time message
120
121       For example:
122
123           I [20/May/1999:19:18:28 +0000] [Job 1] Queued on 'DeskJet' by 'mike'.
124           D [20/May/1999:19:18:28 +0000] [Job 1] argv[0]="DeskJet"
125           D [20/May/1999:19:18:28 +0000] [Job 1] argv[1]="1"
126           D [20/May/1999:19:18:28 +0000] [Job 1] argv[2]="mike"
127           D [20/May/1999:19:18:28 +0000] [Job 1] argv[3]="myjob"
128           D [20/May/1999:19:18:28 +0000] [Job 1] argv[4]="1"
129           D [20/May/1999:19:18:28 +0000] [Job 1] argv[5]="media=
130             na_letter_8.5x11in sides=one-sided"
131           D [20/May/1999:19:18:28 +0000] [Job 1] argv[6]="/var/spool/cups/
132             d000001-001"
133           I [20/May/1999:19:21:02 +0000] [Job 2] Queued on 'DeskJet' by 'mike'.
134           I [20/May/1999:19:22:24 +0000] [Job 2] Canceled by 'mike'.
135
136       The level field contains the type of message:
137
138       A    Alert message (LogLevel alert)
139
140       C    Critical error message (LogLevel crit)
141
142       D    Debugging message (LogLevel debug)
143
144       d    Detailed debugging message (LogLevel debug2)
145
146       E    Normal error message (LogLevel error)
147
148       I    Informational message (LogLevel info)
149
150       N    Notice message (LogLevel notice)
151
152       W    Warning message (LogLevel warn)
153
154       X    Emergency error message (LogLevel emerg)
155
156       The date-time field contains the date and time of when the page started
157       printing.  The format of this field is identical to the data-time field
158       in the access_log file.
159
160       The message field contains a free-form textual message.  Messages  from
161       job filters are prefixed with "[Job NNN]" where "NNN" is the job ID.
162
163   PAGE LOG FILE FORMAT
164       The  page_log file lists each page or group of pages that are sent to a
165       printer.  By default, each line contains the following information:
166
167           printer user job-id date-time page-number num-copies job-billing
168             job-originating-host-name job-name media sides
169
170           printer user job-id date-time total num-impressions job-billing
171             job-originating-host-name job-name media sides
172
173       For example the entries for a two page job called  "myjob"  might  look
174       like:
175
176           DeskJet root 1 [20/May/1999:19:21:05 +0000] 1 1 acme-123
177             localhost myjob na_letter_8.5x11in one-sided
178           DeskJet root 1 [20/May/1999:19:21:05 +0000] 2 1 acme-123
179             localhost myjob na_letter_8.5x11in one-sided
180
181           DeskJet root 1 [20/May/1999:19:21:06 +0000] total 2 acme-123
182             localhost myjob na_letter_8.5x11in one-sided
183
184       The  PageLogFormat  directive  in the cupsd.conf(5) file can be used to
185       change this information.
186
187       The printer field contains the name of the  printer  that  printed  the
188       page.   If  you  send a job to a printer class, this field will contain
189       the name of the printer that was assigned the job.
190
191       The user field contains the name of the user (the IPP  requesting-user-
192       name attribute) that submitted this file for printing.
193
194       The job-id field contains the job number of the page being printed.
195
196       The date-time field contains the date and time of when the page started
197       printing.  The format of this field is identical to the data-time field
198       in the access_log file.
199
200       The  page-number and num-copies fields contain the page number and num‐
201       ber of copies being printed of that page.   For  printers  that  cannot
202       produce copies on their own, the num-copies field will always be 1.
203
204       Lines  containing  the  keyword  "total"  have  a num-impressions field
205       instead which provides the total number  of  impressions  (sides)  that
206       have been printed on for the job.
207
208       The  job-billing  field  contains  a  copy  of  the job-billing or job-
209       account-id attributes provided with the  IPP  Create-Job  or  Print-Job
210       requests or "-" if neither was provided.
211
212       The job-originating-host-name field contains the hostname or IP address
213       of the client that printed the job.
214
215       The job-name field contains a copy of the job-name  attribute  provided
216       with  the  IPP Create-Job or Print-Job requests or "-" if none was pro‐
217       vided.
218
219       The media field contains a copy of the  media  or  media-col/media-size
220       attribute provided with the IPP Create-Job or Print-Job requests or "-"
221       if none was provided.
222
223       The sides field contains a copy of the sides  attribute  provided  with
224       the IPP Create-Job or Print-Job requests or "-" if none was provided.
