# As shipped, the snmpd demon will only respond to queries on the
8a419f
# system mib group until this file is replaced or modified for
8a419f
# security purposes.  Examples are shown below about how to increase the
8a419f
# level of access.
8a419f
8a419f
# By far, the most common question I get about the agent is "why won't
8a419f
# it work?", when really it should be "how do I configure the agent to
8a419f
# allow me to access it?"
8a419f
#
8a419f
# By default, the agent responds to the "public" community for read
8a419f
# only access, if run out of the box without any configuration file in 
8a419f
# place.  The following examples show you other ways of configuring
8a419f
# the agent so that you can change the community names, and give
8a419f
# yourself write access to the mib tree as well.
8a419f

# Process checks.
8a419f
#
8a419f
#  The following are examples of how to use the agent to check for
8a419f
#  processes running on the host.  The syntax looks something like:
8a419f
#
8a419f
#  proc NAME [MAX=0] [MIN=0]
8a419f
#
8a419f
#  NAME:  the name of the process to check for.  It must match
8a419f
#         exactly (ie, http will not find httpd processes).
8a419f
#  MAX:   the maximum number allowed to be running.  Defaults to 0.
8a419f
#  MIN:   the minimum number to be running.  Defaults to 0.
8a419f
8a419f
#
8a419f
#  Examples (commented out by default):
8a419f
#
8a419f
8a419f
#  Make sure mountd is running
8a419f
#proc mountd
8a419f
8a419f
#  Make sure there are no more than 4 ntalkds running, but 0 is ok too.
8a419f
#proc ntalkd 4
8a419f
8a419f
#  Make sure at least one sendmail, but less than or equal to 10 are running.
8a419f
#proc sendmail 10 1
8a419f
8a419f
#  A snmpwalk of the process mib tree would look something like this:
