Notification if server unreachable?
Is it possible for a group of servers to monitor each other and then send an alert if one of them is no longer 'alive'?
Or if its easier have one server that monitors the other five and then sends an alert.
If so how would this be done?
Thanks

globus-rls-admin
globus-rls-admin(8) System Manager's Manual globus-rls-admin(8)
NAME
globus-rls-admin - Replica Location Service Administration
SYNOPSIS
globus-rls-admin -A|-a|-C option value|-c option|-D|-d|-e|-p|-q|-r|-S|-s|-t timeout|-u|-v [ rli ] [ pattern ] [ server ]
DESCRIPTION
The program globus-rls-admin performs administrative operations on a RLS server (see globus-rls-server(8)).
OPTIONS
-A Add rli to list of RLI servers updated by an LRC server using Bloom filters. Note that partitions are not supported with Bloom fil-
ters, the LRC server maintains one Bloom filter for all LFNs in its database, which is sent to all RLI servers configured to receive
Bloom filter updates with this option.
-a Add rli and optionally pattern to the list of RLI servers that the LRC server sends updates to (using a list of LFNs). If pattern
is specified then only LFNs matching it will be sent to rli. If rli is added with no patterns, then it is sent all updates. Pat-
tern matching is done using standard Unix file globbing (see fnmatch(3) or sh(1)).
-C option value
Set server option to value. Note this does not update the configuration file, the next time the server is restarted the configura-
tion change will be lost.
-c option
Retrieve configuration value for specified option from server. If option is "all" then all options are retrieved.
-D Remove rli and pattern from list of RLI servers that the RLI server sends updates to. If pattern is not specified then all entries
for rli are removed. Note if all patterns are removed separately then rli is sent all updates. To stop any updates from being sent
to rli do not specify pattern
-d Remove rli and pattern from list of RLI servers that the LRC server sends updates to. If pattern is not specified then all entries
for rli are removed. Note if all patterns are removed separately then rli is sent all updates. To stop any updates from being sent
to rli do not specify pattern
-e Clear LRC database. Removes all lfn,pfn mappings.
-p Verifies that the server is responding.
-q Cause RLS server to exit.
-r Add rli and optionally pattern to the list of RLI servers that the RLI server sends updates to. If pattern is specified then only
LFNs matching it will be sent to rli. If rli is added with no patterns, then it is sent all updates. Pattern matching is done
using standard Unix file globbing (see fnmatch(3) or sh(1)).
-S Show statistics and other information gathered by RLS server. Intended to be input into GRIS.
-s Show list of RLI servers and patterns being sent updates by the LRC server. If rli or pattern are not specified they are considered
wildcards.
-t timeout
Set timeout (in seconds) for RLS server requests. Default is 30 seconds.
-u Cause LRC server to immediately start full softstate updates to any RLI servers previously added with the -a option.
-v Show version and exit.
