Store Wowza Streaming Engine logs in a PostgreSQL database (legacy)

This article describes how to set up Wowza Streaming Engine™ media server software logging to a PostgreSQL database using the Apache log4j logging utility.

  1. Download the PostgreSQL JDBC Driver to the Wowza Streaming Engine installation folder [install-dir]/lib.
  2. In PostgreSQL admin, create a database named "wowzalogs", then open a SQL window and create the following table:
CREATE TABLE accesslog
  logid serial NOT NULL,
  date character varying(100),
  "time" character varying(100),
  tz character varying(100),
  xevent character varying(20),
  xcategory character varying(20),
  xseverity character varying(100),
  xstatus character varying(100),
  xctx character varying(100),
  xcomment character varying(255),
  xvhost character varying(100),
  xapp character varying(100),
  xappinst character varying(100),
  xduration character varying(100),
  sip character varying(100),
  sport character varying(100),
  suri character varying(255),
  cip character varying(100),
  cproto character varying(100),
  creferrer character varying(255),
  cuseragent character varying(100),
  cclientid character varying(25),
  csbytes character varying(20),
  scbytes character varying(20),
  xstreamid character varying(20),
  xspos character varying(20),
  csstreambytes character varying(20),
  scstreambytes character varying(20),
  xsname character varying(100),
  xsnamequery character varying(100),
  xfilename character varying(100),
  xfileext character varying(100),
  xfilesize character varying(100),
  xfilelength character varying(100),
  xsuri character varying(255),
  xsuristem character varying(255),
  xsuriquery character varying(255),
  csuristem character varying(255),
  csuriquery character varying(255),
  CONSTRAINT "PK_accesslog" PRIMARY KEY (logid)
ALTER TABLE accesslog OWNER TO postgres;
  1. Open the Wowza Streaming Engine file [install-dir]/conf/ in a text editor.
  2. In the first line, add a new root category "SQ":
log4j.rootCategory=INFO, stdout, serverAccess, serverError, <b>SQ</b>
  1. In the same file, copy in the following appender. You will have to modify the password and possibly the URL for the location of the database and the user as necessary:
log4j.appender.SQ.sql=INSERT INTO accesslog (date, time, tz, xevent, xcategory, xseverity,xstatus,xctx,xcomment,xvhost,xapp,xappinst,xduration,sip,sport,suri,cip,cproto,creferrer,cuseragent,cclientid,csbytes,scbytes,xstreamid, xspos,csstreambytes,scstreambytes,xsname,xsnamequery,xfilename,xfileext,xfilesize,xfilelength,xsuri, xsuristem,xsuriquery,csuristem,csuriquery) VALUES ('%X{date}', '%X{time}', '%X{tz}', '%X{x-event}', '%X{x-category}', '%X{x-severity}', '%X{x-status}', '%X{x-ctx}', '%X{x-comment}', '%X{x-vhost}', '%X{x-app}', '%X{x-appinst}', '%X{x-duration}', '%X{s-ip}', '%X{sport}', '%X{s-uri}', '%X{c-ip}', '%X{c-proto}', '%X{c-referrer}', '%X{c-user-agent}', '%X{c-client-id}', '%X{cs-bytes}', '%X{scbytes}', '%X{x-stream-id}', '%X{x-spos}','%X{cs-stream-bytes}', '%X{sc-stream-bytes}', '%X{x-sname}', '%X{x-sname-query}', '%X{x-file-name}', '%X{x-file-ext}', '%X{x-file-size}', '%X{x-file-length}','%X{x-suri}','%X{x-suri-stem}', '%X{x-suri-query}', '%X{c-suri-stem}', '%X{c-suri-query}');
  1. Restart Wowza Streaming Engine and check the table:
select * from accesslog;
  • Start Wowza Streaming Engine in the console or IDE to see any errors that occur.
  • Some fields might need to be longer to accommodate all possible values.
