Probably your simplest option would be to write a small script.

To monitor the processes use the "ps" command, like in the following script sketch:

Code:
while : ; do
     if [ $(ps -fe | grep "<processname>" | wc -l) -le <minimum_nr_plus_1> ] ; then
          show_error "Not all processes seem to run."
     fi
     sleep <nr_of_seconds>
done

To monitor the memory is more tricky: (almost) all otherwise unused memory is used by the OS for caching purposes, so monitoring "free memory" is completely useless - you get constantly "nearly all memory used" as a result, regardless of how much memory is in fact used by applications.


If you are not interested in exact memory consumption, but only in avoiding paging you could monitor the utilization of the paging space(s) by "lsps -a":

Code:
while : ; do
     if [ $(lsps -s | sed '1d;s/^.*\([0-9][0-9]*\)%.*$/\1/') -gt <threshold_value>] ; then
          show_error "Paging space utilization exceeded."
     sleep <nr_of_seconds>
done

Tomcat is an application and could be monitored like any other process (see above)

Monitoring network connectivity is relatively easy, but with a catch: if the network connection goes down the machine has usually no way of advertising this fact. The best solution is to monitor the system from another host, like in the following sketch:

Code:
while : ; do
     if [ $(ping -c1 <host_to_monitor1>; echo $?) -gt 0 ] ; then
          show_error "Cannot reach <host_to_monitor1>"
     fi
     if [ $(ping -c1 <host_to_monitor2>; echo $?) -gt 0 ] ; then
          show_error "Cannot reach <host_to_monitor2>"
     fi
     [ ...]
     sleep <nr_of_seconds>
done

I hope this helps.

HOBBITWEB(5)							File Formats Manual						      HOBBITWEB(5)

NAME

       Xymon web page headers, footers and forms.

DESCRIPTION

       The  Xymon  webpages  are  somewhat  customizable, by modifying the header- and footer-templates found in the ~xymon/server/web/ directory.
       There are usually two or more files for a webpage: A template_header file which is the header for this webpage, and a template_footer  file
       which is the footer.  Webpages where entry forms are used have a template_form file which is the data-entry form.

       With  the  exception of the bulletin files, the header files are inserted into the HTML code at the very beginning and the footer files are
       inserted at the bottom.

       The following templates are available:

       bulletin
	      A bulletin_header and bulletin_footer is not shipped with Xymon, but if they exist then the content of these files will be  inserted
	      in  all  HTML  documents generated by Xymon. The "bulletin_header" contents will appear after the normal header for the webpage, and
	      the "bulletin_footer" will appear just before the normal footer for the webpage. These files can be used to post important  informa-
	      tion about the Xymon system, e.g. to notify users of current operational or monitoring problems.
