The Metacat servlet provides an 'action' for retrieving a log of the
|
|
32
|
events that have occurred, including document insertions, updates,
|
|
33
|
deletes, and reads. This allows a simple reporting facility where
|
|
34
|
event reports can be output in XML format. The report can be subset to
|
|
35
|
only include events from a particular IP address, user, event type,
|
|
36
|
after a start date, or before an end date.
|
|
37
|
</p>
|
|
38
|
<p>
|
|

|
The basic log can be viewed using the <code>getlog</code> servlet
|
|
40
|
action, as in the following URL:<br>
|
|
41
|
<code>http://some.metacat.host/context/metacat?action=getlog</code>
|
|
42
|
</p>
|
|
43
|
<p>
|
|
44
|
This will return an XML formatted log of all events since the log was
|
|
45
|
initiated, which can be quite extensive. To subset the report, provide
|
|
46
|
parameters to restrict the set of matching events:
|
|
47
|
<ul>
|
|
48
|
<li>ipAddress -- restrict the report to this ipAddress (repeatable)</li>
|
|
49
|
<li>principal -- restrict the report to this principal (repeatable)</li>
|
|
50
|
<li>docid -- restrict the report to this docid (repeatable)</li>
|
|
51
|
<li>event -- restrict the report to this event type (repeatable)
|
|
52
|
<ul>
|
|
53
|
<li><code>insert</code></li>
|
|
54
|
<li><code>update</code></li>
|
|
55
|
<li><code>delete</code></li>
|
|
56
|
<li><code>read</code></li>
|
|
57
|
</ul>
|
|
58
|
</li>
|
|
59
|
<li>start -- restrict the report to events after this date
|
|
60
|
<ul>
|
|
61
|
<li><code>YYYY-MM-DD+hh:mm:ss</code></li>
|
|
62
|
</ul>
|
|
63
|
</li>
|
|
64
|
<li>end -- restrict the report to events before this date
|
|
65
|
<ul>
|
|
66
|
<li><code>YYYY-MM-DD+hh:mm:ss</code></li>
|
|
67
|
</ul>
|
|
68
|
</li>
|
|

|
</ul>

Some example queries follow. To view only the 'read' events, use a url like:<br>
|
|
73
|
<code>http://some.metacat.host/context/metacat?action=getlog&event=read</code>
|
|
74
|
</p>
|
|
75
|
<p>
|
|
76
|
To view only the events for a particular IP address, use a url like:<br>
|
|
77
|
<code>http://some.metacat.host/context/metacat?action=getlog&ipaddress=107.9.1.31</code>
|
|
78
|
</p>
|
|
79
|
<p>
|
|
80
|
To view only the events for a given user, use a url like:<br>
|
|
81
|
<code>http://some.metacat.host/context/metacat?action=getlog&principal=uid=johndoe,o=NCEAS,dc=ecoinformatics,dc=org</code>
|
|
82
|
</p>
|
|
83
|
<p>
|
|
84
|
To view only the events for a particular document, use a url like:<br>
|
|
85
|
<code>http://some.metacat.host/context/metacat?action=getlog&docid=knb.5.1</code>
|
|
86
|
</p>
|
|
87
|
<p>
|
|
88
|
To view only the events after a given date, use a url like:<br>
|
|
89
|
<code>http://some.metacat.host/context/metacat?action=getlog&start=2004-09-15+12:00:00</code>
|
|
90
|
</p>
|
|
91
|
<p>
|
|
92
|
To view only the events before a given date, use a url like:<br>
|
|
93
|
<code>http://some.metacat.host/context/metacat?action=getlog&end=2004-09-15+12:00:00</code>
|
|
94
|
</p>
|
|
95
|
<p>
|
|
96
|
Query parameters can be combined, so to view the 'insert' events for September 2004 use a url like:<br>
|
|
97
|
<code>http://some.metacat.host/context/metacat?action=getlog&event=insert&start=2004-09-01+12:00:00&end=2004-09-30+23:59:59</code>
|
|
98
|
</p>
|
|

The log is returned in XML format. Here is an example log format:<br>
|
|

|
