# Agent plugin to monitor DB/2 databases on Linux.
#
# Note: The script has to be accessible and executable by the DB/2
# instance users to function properly.
#
# The script is called in two different modes. Without arguments it:
#
# - outputs the db2_version section,
# - collects all db2 instances and databases, and
# - runs the script for each database as an instance user
#
# With arguments the script queries the information for each database and
# outputs the corresponding sections.
