The following parameters on the Siebel Server and environment variables on the Web server enable and configure the Siebel ARM feature. The Siebel ARM parameters and environment variables are equivalent in function and similar in naming convention.
See Table 7 for a listing of each Siebel ARM parameter and its equivalent environment variable. Descriptions of each parameter and environment variable follow the table.
For details on enabling Siebel ARM using these parameters and variables, see Enabling and Configuring Siebel ARM.
Specifies the amount of response measurement detail logged to Siebel ARM files and effectively enables or disables the Siebel ARM feature. This parameter or environment variable has the following settings:
The Siebel ARM framework uses a buffered data generation mechanism. Siebel ARM collects data and stores it in memory. After the in-memory data size reaches a threshold defined by SARM Buffer Size Siebel ARM outputs the stored data to file on a physical disk. The SARM Buffer Size parameter or environment variable is specified in bytes. The default value is 5,000,000 bytes (approximately 5 MB). The valid settings range from 100,000 bytes to 50,000,000 bytes.
NOTE: Siebel ARM also outputs stored data to file based on elapsed time, which is defined by the parameter or environment variable SARM Period. The setting of this parameter may determine the size of the data saved to file rather than the threshold value defined by SARM Buffer Size.
Siebel ARM collects data and stores it in memory. The time period specified by the SARM Period parameter or environment variable determines when Siebel ARM outputs the stored data to file on a physical disk regardless of the value set for SARM Buffer Size. The parameter is specified in minutes, and has a default value of 3 minutes. The valid settings for this parameter range from 1 minute to 60 minutes.
Specifies the maximum number of Siebel ARM files created per component instance. The default value is four, and there is no Siebel-specified upper limit to the number of files Siebel ARM creates. (The parameter or environment variable SARM Data File Size configures how large a file becomes before a new file is stored on the physical disk.)
The number of active Siebel ARM files per component process is 1 plus the value of SARM Max Number of Files. That is, Siebel ARM removes the oldest file for that process only after the SARM Max Number of Files-plus-1 file reaches SARM Data File Size.
Specifies how large a file becomes before Siebel ARM stores data in a new file on the physical disk. The parameter is specified in bytes. The default value is 15000000 bytes (15 MB), and there is no Siebel-specified upper limit to file size.
Until the specified size is reached, Siebel ARM continues to append file segments to the current file. When the file limit is reached, Siebel ARM creates a new file. (The parameter or environment variable SARM Max Number of files configures the number of files maintained by Siebel ARM.)
When Siebel ARM reaches the file number specified by SARM Max Number of Files (that is, there are SARM Max Number of Files of size SARM Data File Size), Siebel ARM removes the first (that is, the oldest) file when the next file reaches the SARM Data File Size limit. Therefore, the maximum amount of disk space used is approximately SARM Max Number of Files + 1 times SARM Data File Size bytes. This amount of memory is per-process (per component instance).
For example, if SARM Data File Size is 15 MB, SARM Max Number of Files is 4, and there are 5 instances (processes) of the component, then the maximum amount of disk space consumed is approximately 375 MB—that is, 15MB per file, times 5 files per process, times 5 processes (instances of component).
