Environment variables are created and/or set by all Seon binaries, which values are based on the configuration of Seon. These variables are:
Seon_CFGFILE: Seon main configuration file (absolute path information)Seon_IN_DIR: incoming data directorySeon_OUT_DIR: outgoing data directorySeon_TMP_DIR: temporary data directorySeon_BIN_DIR: binary program directorySeon_SCRIPT_DIR: script installation directorySeon_BACKUP_DIR: backup directoryRAND_FILE: entropy file for OFTP2 needsOPENSSL_BIN: absolute path to openSSL binaryRRDTOOL_BIN: absolute path to RRDtools binaryRRDB_DATAPATH: RRD data pathSeon_WEBGUI_DIR: web interface installation directoryCA_FILE: configured absolute path to the root certificate fileCA_PATH: configured absolute path to the root certificate directory
The following environment variables are extracted form the global Seon configuration file (default: /etc/seon.conf):
Seon_DB_HOSTSeon_DB_USERSeon_DB_PWDSeon_DB_NAMESeon_DB_SOCKETSeon_DB_PORTSeon_DB_TYPE: either "mysql", "DB2" or "sqlite3"
All processes started by Seon (event scripts, plugins, etc.) have access to these environment variables.
The environment variable "Seon_CFGFILE" points to the absolute path to the Seon main configuration file. This has two effects:
- you may start Seon programs in a shell where this variable is set without using the parameter "
-C" for all binaries (because the environment variable points to the correct position of the configfile) - all subsequent processes started by Seon (like event scripts) don't have to bother about the given configfile (like plugins of Seon Enterprise).
Database performance benchmarking
Available in Seon 3 Core, an environment variable can be set to log all database access timing information into that given file:
Seon_DB_BENCHMARKLOG
You can set this variable to an absolute filename where Seon logs all innformation (example: "ksh" or "bash"):
export Seon_DB_BENCHMARKLOG=/tmp/db2perf.log
This file logs the connect and query time for every single database access, resulting in a fast growing file. The content if this file looks like this (using DB2 database abstraction layer, others like MySQL start with "MySQL"):
DB2 connect: 0.052482 seconds DB2 SQL query: 0.126631 seconds DB2 connect: 0.032447 seconds DB2 SQL query: 0.004983 seconds DB2 connect: 0.029555 seconds DB2 SQL query: 0.004500 seconds DB2 connect: 0.031012 seconds DB2 SQL query: 0.001324 seconds
