OMW-Support Tip:How to modify the collection mechanism

If you want to modify the default collection mechanism, you must modify the settings in the parm.

The parm file is a text file containing the instructions that tell scope to log specific performance measurements.


During fresh installation, the HP Operations agent places the default parm file into two different directories:


On Windows:



**with the extension .mwc (parm.mwc).

On HP-UX, Solaris, and Linux:







The data collection mechanism of scope is controlled by the settings in the parm file located into the %ovdatadir% (for Windows) or /var/opt/perf (for UNIX or Linux) directory.

The parm file that is located into the %ovdatadir% (for Windows) or /var/opt/perf (for UNIX or Linux) directory is the file you want to modify.


When you upgrade the HP Operations agent on a node (from an older version of the HP Performance Agent), the upgrade process updates the copy of the parm file available in the newconfig directory. The parm file that resides into the other directory remains unaffected and continues to govern the data collection mechanism on the node. This method, in effect, enables you to retain the configured data collection mechanism even after upgrade of the product. You can, any time after the product upgrade, compare the existing configuration settings of the parm file with the new version of the parm file available in the newconfig directory, and then make necessary changes.


The parm file is set up to collect an average amount of log file data. The maximum amount depends on your system. See the description of the parameter size in Parameter Descriptions.


Remember that the block of text preceding the setting explains the usage of the command, example of the first command in the file including the file headings:


# @(#) HP Performance Agent parm file for Windows  11.00.000 


# parm file for performance software


# Edit this file as needed to correspond to the specific needs of your system.

# Changes to this configuration file will not take effect until the tools

# are restarted. See the <InstallDir>\examples\ovpaconfig\parm.examples file for

# additional application suggestions.


# This file is read by the  HP Performance Agent product. Refer to the

#  HP Performance Agent documentation for specific information about

# managing scopent data collection.


# The default for the following id parameter is to use the system's

# hostname. If you want to specify a different name for the metric

# GBL_SYSTEM_ID, other than the hostname, uncomment the following and

# replace "system-id" with a different name.


# id = system-id
