Sys
log
Watcher
Sys
log
Watcher is a Windows-based
sys
log
server for corporate networks. The
sys
log
server collects, stores, parses, displays and explains
sys
log
information to both new and professional network administrators, helping to improve the st
ab
ility and reli
ab
ility of the network.
Sys
log
Watcher installs a dedicated
sys
log
server, integrating
log
data from multiple network appliances into a single, easily manage
ab
le and accessible place. Collecting and analyzing
sys
log
s is essential for maintaining network st
ab
ility and auditing network security.
Sys
log
Watcher notifies system administrators
ab
out important
sys
log
messages, allowing you to fix network problems sooner and improving network reli
ab
ility. The
sys
log
server parses both standard-compliant and non-standard messages, easily processing corrupted and non-standard system
log
s without error.
Sys
log
Watcher is designed to work under heavy load, and is
ab
le to process millions of
sys
log
records without a problem.
erlang日志应用
log
4erl（非sasl）
用不惯sasl的，可以用
log
4xxx的erlang版，
log
4erl。
log
4erl Manual: =============== TOC: ==== 1. Features 2. Installation 3. Usage 4. API 5. Configuration 6. Known issues 7. Future development 8. License 1. FEATURES: ============ - Multiple
log
s - Currently, only size-based
log
rotation of files for file appender - Support default
log
ger if no
log
ger specified - 5 predifined
log
levels (debug, info, warn, error, fatal) - A
log
handler for error_
log
ger - Support for user-specified
log
levels - Support for a
log
formatter (similar to Layouts in
Log
4J) - Support for console
log
- Support for smtp formatter - Support for XML
log
s - Support for
sys
log
- Support for changing format and level of appender during run-time 2. INSTALLATION: ================ To compile & install
log
4erl, download source from google code's website (http://code.google.com/p/
log
4erl/) or from svn: $> svn checkout http://
log
4erl.googlecode.com/svn/trunk/
log
4erl or from github public repository (http://github.com/ahmednawras/
log
4erl/). $> cd
log
4erl $> make or you can run the below from erlang shell: $> cd src $> erl 1> make:all([{outdir, "../ebin"}]). 3. USAGE: ========= 1- In order to use
log
4erl, you need to first include it in the path. There are 2 ways to do this: a) include the "
log
4erl" directory in erlang's "lib" directory in the target machine (cp -Rf
log
4erl /where/erlang/is/lib). $> cp -Rf
log
4erl /usr/local/lib/erlang/lib/ b) include the "
log
4erl" ebin directory in the path when running you program $> erl -pz /path/to/
log
4erl ... 2- Once the
log
4erl directory is included, you can use its API as described in section "API". but before, you need to run: > application:start(
log
4erl). 3- Create a configuration file and load it using
log
4erl:conf(File) >
log
4erl:conf("priv/
log
4erl.conf"). 4- Alternatevly, you can create
log
gers & add appenders to them programmatically as appropriate. You can do this as per the API below. >
log
4erl:add_
log
ger(messages_
log
). >
log
4erl:add_console_appender(messages_
log
, cmd_
log
s, {warn, "[%L] %l%n"}). where Conf is the erlang term describing how the
log
is to be handled You can also add more types of appenders, which is explained in API.txt and Appneders_API.txt. 5- Now, you can
log
whatever messages you like as per
log
ging functions described in API. >
log
4erl:info("Information message"). Precedance of
log
levels are: all = debug < info < warn < error < fatal < none User defined levels are always written except when none level is specified in the
log
ger specification (See below). 4. API: ======= Please look at API.txt file for more information
ab
out the API. 5. CONFIGURATION: ================= Please look at CONFIGURATION.txt for more information
ab
out how to configure
log
4erl. 6. KNOWN ISSUES: ================ - Name of both
log
gers & appenders should be unique and not registered since
log
4erl will try and register their names. If the name is already registered, nothing will happen. This will be fixed soon. - If you run change_
log
_format/1,2 and appender crashed, a restart from the supervisor will not record the latest format used. It will only use either the default format or the format used in the argument is supplied. 7. FUTURE DEVELOPMENT: ====================== - Add support for different
log
persistance methods (e.g files, XML, console, DB, SNMP,
sys
log
...etc) - Add support for time-based
log
rotation - Multiple configuration format (Erlang terms, XML?, properties files?) - Add support for NDC & MDC ??? Please send your suggestion to ahmed.nawras
