How to stop monitoring of servers at the time of reboot through shell scripting?
We have number of servers which belongs to platforms Solaris, AIX,HP-UX and LINUX. Monitoring tool 'Patrol Agent' process run on the servers to check for the server health and communicate with the Patrol server through the port 5181. During scheduled reboot and maintenance of servers we do receive alarms/alerts due to the 'Connection Closed' for the nodes. Patrol agent Stop & Start process is automated through shell script during rebooting of the server. Hence we started receiving multiple requests from the users to bring the monitoring of servers into Maintenance mode which is a repeated process and very much time consuming.
So I am just thinking of trying to implement some automation process for keeping the servers in Maintenance mode throughout the time span while server is DOWN. Is there any process that we can implement on the servers through SHELL scripting so that the communication (through the TCP port) between the Patrol Server & Agent can be stopped just before executing the shutdown command and again resuming it as soon as the server is up and running? If so then we can consolidate and execute the new scripts which will stop FALSE alarming .

bubbros-server
bubbros-server(6) Games Manual bubbros-server(6)
NAME
bubbros-server - the bub-n-bros server.
SYNOPSIS
bubbros-server [ level-file.bin ] [options]
DESCRIPTION
bubbros-server starts an http server that acts as a control panel for the server. The server listens on port 8000 by default. The url for
the control panel is http://server:port/0xN where 0xN is a random hex number (acts as minimal protection). This url is printed when the
server starts. You can start and view games and kill the server from this panel. The control panel also allows you to type in the address
of a server to connect to, the script will then open a client to that server. The http server also servers java applet clients for those
players who wish to use one.
When a game is started the script opens a port for the game server. This port can then be connected to by a client. Clients autodetect
servers running on the local network with UDP ping on port 8056.
Connection forming
The client forms a tcp connection to the server. Or, when using the metaserver, the server forms a connection to the client. If this fails,
the client and server try a simultaneous SYN connect. This sometimes works if the server and client are behind firewalls. The server then
tries to transmit the data over udp. If it gets no response from the client it will fall back to the existing tcp connection.
OPTIONS
-b N, --begin N, --start N
Start at board (level) number N. The default is 1. See also the -s option.
-h, --help
Display help.
-i, --infinite
Restart the server at the end of the game. Normally the server quits after a certain period of inactivity. This is useful when used
with the -m option to make a public server that is available for a long time.
-l N, --lives N
Limit number of lives to N. If this option is not specified the number of lives will be infinite.
-m, --metaserver
Register server with the Metaserver (currently) at codespeak.net:8050. This makes your server visible to everybody, and also facil-
itates joining through a fascistic firewall.
--port TYPE=N Sets default listening ports. If type is LISTEN , sets the game server port to N. The game server port is chosen randomly by
default. If the type is HTTP , sets the http server port to N. The http server port defaults to 8000. Another port will be chosen
if none was specified and 8000 is already in use. The server also listens to UDP ping on port 8056.
-s N, --step N
Increase board number with N when a board is completed. Defaults to 1. see also the -b option.
OUTPUT
The server outputs helpful debug information concerning the http and game servers.
