arm4_daemon – ARM 4 collection agent
Synopsis
arm4_daemon –help|-harm4_daemon –version|-V
arm4_daemon [–verbose|-v] [–debug|-d]
Description
The arm4_daemon program collects ARM 4 measurement data from the ARM 4 libraries and saves the measurements in a local database. While there will normally be many instances of the instrumented applications, there will typically be only one instance of the arm4_daemon running at a time.Configuration
Configuration options are set in the configuration file. The default configuration is /etc/arm4.conf, although this can be overridden using the –config command line option. See arm4.conf(5) for more information.Datafiles
The arm4_daemon program uses the Berkeley database to store transaction information. Rather than a single file, this database uses separate files fore each database table. For simplicity, all database files are stored in a single directory. Therefore specifying a database or database archive location is really specifying the directory in which the files are stored. The default location for the database files is /var/lib/arm4/data. For backup files, a time stamped directory is created under /var/lib/arm4/data/backup. Each of these directories can be changed using the arm4.conf configuration file.Options
- -h, –help
- display the command line options
- -V, –Version
- display the program version and exit
- -v, –verbose
- output diagnostic information as the program is run. This may not be suitable when running in the background as a true daemon but can be useful for debugging.
- -C, –Config config_file
- specifies a configuration file for this instance instead of using the default configuration file. The default configuration file /etc/arm4.conf is used if none is specified.
- -d, –debug
- run the daemon as a foreground process. This is primarily used for debugging.
- -s, –stats
- periodically display statistics on the message queues and database processes.
- -o, –off
- Start the agent as a "null" collector. Although the collector is active, no data is actually collected. This can be controlled using the arm4_control utility.
