Overview + + 1.1.1. Rotating Log Files + + 1.2. Parameters + + 1.2.1. flush (integer) + +1.1. Overview + + Flatstore is one of so-called SER database modules. It does not export + any functions executable from the configuration scripts, but it exports + a subset of functions from the database API and thus other module can + use it instead of, for example, mysql module. + + The module does not export all functions of the database API, it + supports only one function, insert. The module is limited but very + fast. It is especially suitable for storing accounting information on + sites with extremely high traffic. If MySQL is too slow or if you get a + huge amount of accounting data then you can consider using this module. + Note that the acc module is the only module that was tested with + flastore. + + The format of the files produced by this module is plain text. Each + line consists of several fields, fields are separated by | character. + New information is always appended at the end of the file, searching, + deleting and updating of existing data is not supported by the module. + + The acc module can be configured to use flatstore module as database + backend using the db_url_parameter: +modparam("acc", "db_url", "flatstore:/var/log/acc") + + This configuration options tells acc module that it should use the + flatstore module and the flatstore module should create all files in + /var/log/acc directory. The directory must exist and SER processes must + have permissions to create files in that directory. + + Name of files in that directory will follow the following pattern: +<table_name>_<process_name>.log + + For example, entries writen by SER process 8 into acc table would be + written in file acc_8.log. For each table there will be several files, + one file for every SER process that wrote some data into that table. + The main reason why there are several files for each table is that it + is much faster to have one file per process, because it does not + require any locking and thus SER processes will not block each other. + To get the complete data for a table you can simply concatenate the + contents of files with the same table name but different process id. + +1.1.1. Rotating Log Files + + There is a new SER FIFO interface command called flat_rotate. When SER + receives the command then it will close and reopen all files used by + flatstore module. The rotation itself has to be done by another + application (such as logrotate). Follow these steps to rotate files + generated by flatstore module: + * Rename the files that you want to rotate: +cd /var/log/acc +mv acc_1.log acc_1.log.20050605 +mv acc_2.log acc_2.log.20050605 +mv acc_4.log acc_3.log.20050605 +... + Note that at this point SER will still be writing all data into the + renamed files. + * Send SER the fifo command to close and reopen the renamed files: +serctl fifo flat_rotate + This will force SER to close the renamed files and open new ones + with original names, such as acc_1.log. New files will be open at + the point when SER has some data to write. It is normal that the + files will be not created immediately if there is no traffic on the + proxy server. + * Move the renamed files somewhere else and process them. + +1.2. Parameters + + Revision History + Revision $Revision$ $Date$ + +1.2.1. flush (integer) + + Enable or disable flushing after each write. + + Default value is 1.
