Hello Don,

We only need to report in case of failures, if the process is running as expected then no need to report.

For all failures in servers list it should append to the file /var/tmp/failed.txt so that we can send out all in 1 email.

List of servers are different, so processes running on them differ. I can append wc -l at the end of script for string comparison if that can address the issue.

Due to large volume of servers its hard to manage/insert script on all servers, we need one host to check for errors and report through email on exact failure, so if new servers are added to list along with new processes then we can just edit/update script in 1 place rather than 1000+.

I will update the script to send email only incase of failures or /var/tmp/failed.txt is found.

Thanks,
Saikrishna

dhcp6relay

DHCP6RELAY(8)						    BSD System Manager's Manual 					     DHCP6RELAY(8)

NAME

     dhcp6relay -- DHCPv6 relay agent

SYNOPSIS

     dhcp6relay [-Ddf] [-b boundaddr] [-H hoplim] [-r relay-IF] [-s serveraddr] [-S script-file] [-p pid-file] interface ...

DESCRIPTION

     dhcp6relay acts as an intermediary to deliver DHCPv6 messages between clients and servers, and is on the same link as a client.  dhcp6relay
     needs command line arguments interface ..., which specifies the list of links accommodating clients.

     Options supported by dhcp6relay are:

     -d      Print debugging messages.

     -D      Even more debugging information is printed.

     -f      Foreground mode (useful when debugging).  Although dhcp6relay usually prints warning, debugging, or error messages to syslog(8), it
	     prints the messages to standard error if this option is specified.

     -b boundaddr
	     Specifies the source address to relay packets to servers (or other agents).

     -H hoplim
	     Specifies the hop limit of DHCPv6 Solicit messages forwarded to servers.

     -r relay-IF
	     Specifies the interface on which messages to servers are sent.  When omitted, the same interface as interface will be used.  When
	     multiple interface are specified, this option cannot be omitted.

     -s serveraddr
	     Specifies the DHCPv6 server address to relay packets to.  If not specified, packets are relayed to ff05::1:3 (All DHCPv6 servers).

     -S script-file
	     Specifies the script file to be executed when dhcp6relay receives a RELAY-REPLY message from a DHCPv6 server.  Further detail of the
	     script file syntax is available in dhcp6c(8)

     -p pid-file
	     Use pid-file to dump the process ID of dhcp6relay.

FILES

     /var/run/dhcp6relay.pid  is the default file that contains pid of the currently running dhcp6relay.

SEE ALSO

     dhcp6c(8), dhcp6s(8)

HISTORY

     The dhcp6relay command first appeared in WIDE/KAME IPv6 protocol stack kit.
